  1. Non-European facilities for elementary particle physics research

    International Nuclear Information System (INIS)

    Mann, A.K.

    1983-01-01

    The facilities we now employ in high energy physics cover a broad spectrum of particle energies and intensities and provide therefore a multiplicity of probes with which to study the behavior of elementary particles. In general, the goal has been to achieve ever higher particle energies and intensities, with emphasis on energy, and to develop more versatile and more sensitive detectors with which to study the resultant particle-particle interactions. Most energy regimes that have been explored have yielded new, fundamental information which often becomes clearer and more easily developed when particle energies are further increased. In this talk I shall try to delineate the nature of those facilities in Canada, Japan and the U.S.A. It is useful, I believe, to begin with a brief discussion of the funding and management of facilities in those countries and a short summary of recent history. The main body of the talk concentrates on the present, planned and contemplated facilities of the major non-European accelerator laboratories, and address briefly the status of accelerator development. The concluding section will summarize the salient features of the discussion. (author)

  6. A Word from the DG: Preparing the strategy for European particle physics

    CERN Multimedia

    2006-01-01

    Particle physics is an increasingly globalized field, with the LHC marking the turning point from regional to world-wide organization. Although still a European-led project, the LHC is the first accelerator that CERN has built with help from non-Member States, and its experiments are the most international collaboration that particle physics has ever known. For Europe to engage in this process of globalization for future projects, and to maintain a leading position in the field, we need a European strategy. The European Commission is considering introducing basic research in possible actions during its R&D framework programme (2007-2013). It is with this in mind that the CERN Council established a strategy group in 2005. The group was asked to define and prioritize technical options in preparing a long-term vision for European particle physics for presentation to Council at a special meeting in Lisbon on 14 July this year. CERN Council's decision to establish the strategy group recognizes the distinctio...

  7. A word from the DG: The European strategy for particle physics

    CERN Multimedia

    2006-01-01

    The CERN Council took the bold and important decision of unanimously approving a European strategy for particle physics at a dedicated meeting held in Lisbon on 14 July. The consequences for particle physics and for this Laboratory are profound. The full strategy statement is available through the CERN Council web pages at the address http://www.cern.ch/council-strategygroup, but I would like to underline some of the key points here. In endorsing the strategy, the Council has agreed to act as a council for European particle physics, and not only as a council for CERN. The Council has accepted the considerable responsibility of defining and updating Europe's strategy for particle physics, and of representing Europe on the world stage. The general issues of the strategy recognize Europe's strength and depth in the field, at strong national institutes, at universities and laboratories, and at CERN. The scientific issues place the LHC firmly on top of the list, both in terms of its initial exploitation and possi...

    The high energy physics group at the University of South Carolina, under the leadership of Profs. S.R. Mishra, R. Petti, M.V. Purohit, J.R. Wilson (co-PI's), and C. Rosenfeld (PI), engaged in studies in "Experimental Particle Physics." The group collaborated with similar groups at other universities and at national laboratories to conduct experimental studies of elementary particle properties. We utilized the particle accelerators at the Fermi National Accelerator Laboratory (Fermilab) in Illinois, the Stanford Linear Accelerator Center (SLAC) in California, and the European Center for Nuclear Research (CERN) in Switzerland. Mishra, Rosenfeld, and Petti worked predominantly on neutrino experiments. Experiments conducted in the last fifteen years that used cosmic rays and the core of the sun as a source of neutrinos showed conclusively that, contrary to the former conventional wisdom, the "flavor" of a neutrino is not immutable. A neutrino of flavor "e," "mu," or "tau," as determined from its provenance, may swap its identity with one of the other flavors -- in our jargon, they "oscillate." The oscillation phenomenon is extraordinarily difficult to study because neutrino interactions with our instruments are exceedingly rare -- they travel through the earth mostly unimpeded -- and because they must travel great distances before a substantial proportion have made the identity swap. Three of the experiments that we worked on, MINOS, NOvA, and LBNE utilize a beam of neutrinos from an accelerator at Fermilab to determine the parameters governing the oscillation. Two other experiments that we worked on, NOMAD and MIPP, provide measurements supportive of the oscillation experiments. Good measurements of the neutrino oscillation parameters may constitute a "low energy window" on related phenomena that are otherwise unobservable because they would occur only at energies way above the reach of conceivable accelerators. Purohit and Wilson participated in the Ba

    The cosmic connections between physics on the very largest and very smallest scales are reviewed with an emphasis on the symbiotic relation between elementary particle physics and cosmology. After a review of the early Universe as a cosmic accelerator, various cosmological and astrophysical constraints on models of particle physics are outlined. To illustrate this approach to particle physics via cosmology, reference is made to several areas of current research: baryon non-conservation and baryon asymmetry; free quarks, heavy hadrons and other exotic relics; primordial nucleosynthesis and neutrino masses.

    This series of lectures is about the role of particle physics in physical processes that occurred in the very early stages of the bug gang. Of particular interest is the role of particle physics in determining the evolution of the early Universe, and the effect of particle physics on the present structure of the Universe. The use of the big bang as a laboratory for placing limits on new particle physics theories will also be discussed. Section 1 reviews the standard cosmology, including primordial nucleosynthesis. Section 2 reviews the decoupling of weakly interacting particles in the early Universe, and discusses neutrino cosmology and the resulting limits that may be placed on the mass and lifetime of massive neutrinos. Section 3 discusses the evolution of the vacuum through phase transitions in the early Universe and the formation of topological defects in the transitions. Section 4 covers recent work on the generation of the baryon asymmetry by baryon-number violating reactions in Grand Unified Theories, and mentions some recent work on baryon number violation effects at the electroweak transition. Section 5 is devoted to theories of cosmic inflation. Finally, Section 6 is a discussion of the role of extra spatial dimensions in the evolution of the early Universe. 78 refs., 32 figs., 6 tabs

    Green, Dan

    1994-01-01

    The aim of this book on particle physics is to present the theory in a simple way. The style and organization of the material is unique in that intuition is employed, not formal theory or the Monte Carlo method. This volume attempts to be more physical and less abstract than other texts without degenerating into a presentation of data without interpretation.This book is based on four courses of lectures conducted at Fermilab. It should prove very useful to advanced undergraduates and graduate students.

  15. Cosmology and particle physics

    International Nuclear Information System (INIS)

    Salati, P.

    1986-01-01

    If the hot Big Bang model is correct, the very early universe provides us with a good laboratory to test our ideas on particle physics. The temperature and the density at that time are so high that each known particle must exist in chemical and in thermal equilibrium with the others. When the universe cools, the particles freeze out, leaving us today with a cosmic background. Such a kind of relic is of great interest because we can probe the Big Bang Model by studying the fossilized gas of a known particle. Conversely we can use that model to derive information about a hypothetical particle. Basically the freezing of a gas occurs a temperature T o and may be thermal or chemical. Studying the decoupling of a stable neutrino brings information on its mass: if the mass M ν lies in the forbidden range, the neutrino has to be unstable and its lifetime is constrained by cosmology. As for the G.U.T. Monopole, cosmology tells us that its present mass density is either to big or to small (1 monopole/observable universe) owing to a predicted flux far from the Parker Limit. Finally, the super red-giant star life time constrains the axion or the Higgs to be more massive than .2 MeV [fr

  17. Prospects of particle physics

    International Nuclear Information System (INIS)

    Meyer-Berkhout, U.

    1986-01-01

    Remarkable progress has been achieved in the last two decades in the field of particle physics. From the insight gained by the many experimental data, physicists derive a framework picture of matter on the sub-nuclear level, consisting of fundamental components which interact with each other in a defined and quantitatively detectable manner. The data now available allowed a quantum field theory of strong interactions to be set up for the first time, and a unified theory of electromagnetic and weak interaction. Particle physicists today take particular interest in the problem of whether the strong interaction might fit into an extended unified theory. Such a grand unified theory would have a far-reaching impact on the conceptual models both of the cosmic and sub-nuclear dimensions, and possibly lead to observable effects in domains of energy and mass which will be opened up for experiments by the new accelerator generation underway. Current activities throughout the world for constructing or projecting the new high-energy particle accelerators are outlined in the article, together with the prospects expected by particle physicists, and a look back on the history and achievements of this field of science.

  18. Elementary particle physics: Experimental

    International Nuclear Information System (INIS)

    Lord, J.J.; Burnett, T.H.; Wilkes, R.J.

    1989-01-01

    We are carrying out a research program in high energy experimental particle physics. Studies of high energy hadronic interactions and leptoproduction processes continue using several experimental techniques. Progress has been made on the study of multiparticle production processes in nuclei. Ultra-high energy cosmic ray nucleus-nucleus interactions have been investigated by the Japanese American Cosmic Emulsion Experiment (JACEE) using balloon-borne emulsion chamber detectors. In the area of particle astrophysics, our studies of cosmic ray nuclear interactions have enabled use to make the world's most accurate determination of the comparison of the cosmic rays above 10 13 eV. We have only the detector that can observe interaction vertices and identify particles at energies up to 10**15 eV. Our observations are getting close to placing limits on the acceleration mechanisms postulated for pulsars in which the spin and magnetic moment axes are at different angles. In June, 1989 approval was given by NASA for our participation in the Space Station program. The SCINATT experiment will make use of emulsion chamber detectors, similar to the planned JACEE hybrid balloon flight detectors. These detector will permit precise determination of secondary particle charges, momenta and rapidities, and the accumulation of data will be at least a factor of 10 to 100 greater than in balloon experiments. Emulsion chamber techniques ate also employed in an experiment using accelerator heavy ion beams at CERN and Brookhaven National Laboratory to investigate particle production processes in central collisions of nuclei in the energy range 15 -- 200A GeV. Our study of hadroproduction in lepton interactions is continuing with approval of another 8 months run for deep inelastic muon scattering experiment E665 at Fermilab

    2012-01-01

    CERN physicists, take out your smartphones! Two new particle physics applications for Android phones have been developed by a physicist from the University of Bern: “Particle Properties” and “Particle Physics Booklet 2010”.   “When I'm on shift, I enjoy looking at the online event displays,” says Igor Kreslo from the Laboratory for High Energy Physics at the University of Bern, the physicist who has developed the two particle physics applications for Android. “Sometimes very beautiful events appear, with many different particles. I like to discuss these displays with my students, just to develop their ability to identify particles. We try to find out which particle is which and how it might decay… I think that's the best way to teach students the phenomenology of particle physics.” When scientists study particle physics, they require some vital information, such as the decay branching ...

    2015-02-02

    This report details the accomplishments and research results for the High Energy Physics Group at the University of Texas at Arlington at the Energy and Intensity Frontiers. For the Energy Frontier we have made fundamental contributions in the search for supersymmetric particles, proposed to explain the stabilization of the mass of the Higgs Boson – the agent giving mass to all known particles. We have also made major contributions to the search for additional Higgs Bosons and to the planning for future searches. This work has been carried out in the context of the ATLAS Experiment at CERN (European Nuclear Research Laboratory) and for which we have made major contributions to computing and data distribution and processing, and have worked to calibrate the detector and prepare upgraded electronics for the future. Our other contribution to the Energy Frontier has been to the International Linear Collider (ILC) project, potentially hosted by Japan, and to the Silicon Detector Concept (SiD) in particular. We have lead the development of the SiD Concept and have worked on a new form of precise energy measurement for particles from the high energy collisions of electrons and positrons at the ILC. For the Intensity Frontier, we have worked to develop the concept of Long Baseline Neutrino Experiment(s) (LBNE) at the Fermi National Accelerator Laboratory. Our contributions to detector development, neutrino beam studies, particle identification, software development will facilitate future studies of the oscillation of one type of neutrino into other type(s), establish the order of the neutrino masses, and, through an innovative new idea, allow us to create a beam of dark matter particles.

  11. Overview of particle physics

    International Nuclear Information System (INIS)

    Salam, A.

    1986-02-01

    An overview of the situation of particle physics at the end of 1985 is given. It includes the following topics: ideas which have been tested or will soon be tested such as the standard model based on the symmetry group SUsub(C)(3)xSUsub(L)(2)xU(1), light Higgs and preons; theoretical ideas whose time has not yet come (basically because no accelerators are being constructed to test them) such as N=1 supersymmetry and N=1 supergravity right-handed weak currents, extended supergravities and superstring models; ideas for which non-accelerator and passive experiments have been mounted such as proton decay, nn-bar oscillations, neutrino masses and oscillations, monopoles and dark matter

  12. Cosmology and particle physics

    International Nuclear Information System (INIS)

    Turner, M.S.

    1986-01-01

    Progress in cosmology has become linked to progress in elementary particle physics. In these six lectures, the author illustrates the two-way nature of the interplay between these fields by focusing on a few selected topics. In the next section the author reviews the standard cosmology, especially concentrating on primordial nucleosynthesis and discusses how the standard cosmology has been used to place constraints on the properties of various particles. Grand Unification makes two striking predictions: (i) B non-conservation; (ii) the existence of stable, superheavy magnetic monopoles. Both have had great cosmological impact. In the following section the author discusses baryogenesis, the very attractive scenario in which the B,C,CP violating interactions in GUTs provide a dynamical explanation for the predominance of matter over antimatter and the present baryon-to-photon ratio. Monopoles are a cosmological disaster and an astrophysicist's delight. In Section 4 discusses monopoles, cosmology, and astrophysics. In the fourth lecture the author discusses how a very early (t≤10/sup -34/ sec) phase transition associated with spontaneous symmetry breaking (SSB) has the potential to explain a handful of very fundamental cosmological facts, facts which can be accommodated by the standard cosmology, but which are not ''explained'' by it. The fifth lecture is devoted to a discussion of structure formation in the universe

    1991-01-01

    We are continuing a research program in particle astrophysics and high energy experimental particle physics. We have joined the DUMAND Collaboration, which is constructing a deep undersea astrophysical neutrino detector near Hawaii. Studies of high energy hadronic interactions using emulsion chamber techniques were also continued, using balloon flight exposures to ultra-high cosmic ray nuclei (JACEE) and accelerator beams. As members of the DUMAND Collaboration, we have responsibility for development a construction of critical components for the deep undersea neutrino detector facility. We have designed and developed the acoustical positioning system required to permit reconstruction of muon tracks with sufficient precision to meet the astrophysical goals of the experiment. In addition, we are making significant contributions to the design of the database and triggering system to be used. Work has been continuing in other aspects of the study of multiparticle production processes in nuclei. We are participants in a joint US/Japan program to study nuclear interactions at energies two orders of magnitude greater than those of existing accelerators, using balloon-borne emulsion chambers. On one of the flights we found two nuclear interactions of multiplicity over 1000 -- one with a multiplicity of over 2000 and pseudorapidity density ∼ 800 in the central region. At the statistical level of the JACEE experiment, the frequency of occurrence of such events is orders of magnitude too large. We have continued our ongoing program to study hadronic interactions in emulsions exposed to high energy accelerator beams

    Wiener, Gerfried

    2017-01-01

    Current physics education research is faced with the important question of how best to introduce elementary particle physics in the classroom early on. Therefore, a learning unit on the subatomic structure of matter was developed, which aims to introduce 12-year-olds to elementary particles and fundamental interactions. This unit was iteratively evaluated and developed by means of a design-based research project with grade-6 students. In addition, dedicated professional development programmes were set up to instruct high school teachers about the learning unit and enable them to investigate its didactical feasibility. Overall, the doctoral research project led to successful results and showed the topic of elementary particle physics to be a viable candidate for introducing modern physics in the classroom. Furthermore, thanks to the design-based research methodology, the respective findings have implications for both physics education and physics education research, which will be presented during the PhD defen...

    White, Martin

    2017-10-01

    Following the discovery of the Higgs boson in 2012, particle physics has entered its most exciting and crucial period for over 50 years. In this book, I first summarise our current understanding of particle physics, and why this knowledge is almost certainly incomplete. We will then see that the Large Hadron Collider provides the means to search for the next theory of particle physics by performing precise measurements of the Higgs boson, and by looking directly for particles that can solve current cosmic mysteries such as the nature of dark matter. Finally, I will anticipate the next decade of particle physics by placing the Large Hadron Collider within the wider context of other experiments. The results expected over the next ten years promise to transform our understanding of what the Universe is made of and how it came to be.

  13. Dark matter and particle physics

    International Nuclear Information System (INIS)

    Peskin, Michael E.

    2007-01-01

    Astrophysicists now know that 80% of the matter in the universe is 'dark matter', composed of neutral and weakly interacting elementary particles that are not part of the Standard Model of particle physics. I will summarize the evidence for dark matter. I will explain why I expect dark matter particles to be produced at the CERN LHC. We will then need to characterize the new weakly interacting particles and demonstrate that they the same particles that are found in the cosmos. I will describe how this might be done. (author)

    MacGregor, I.J.D.; Doyle, A.T.

    1993-01-01

    This item documents the International Conference on Nuclear and Particle Physics held at the University of Glasgow, UK, from 30th March to 1st April 1993. It was organised by the Department of Physics and Astronomy at Glasgow University on behalf of the Nuclear and Particle Physics Division of the Institute of Physics. The scientific programme covered many areas of current interest in nuclear and particle physics. Particle physics topics included up to the minute reports on the physics currently coming from CERN'S Low Energy Antiproton Ring (LEAR), Hadron-Elektron-Ring Analage (HERA) and Large Electron-Positron Storage Rings (LEP), and reviews of quantum chromodynamics (QCD) lattice gauge theory. Looking to the future the programme covered the search for the Higgs boson and a review of physics experiments planned for the new generation of accelerators at Large Hadron Collider (LHC) and Superconducting Supercollider (SSC). The conference coincided with the final closure of the world class Nuclear Structure Facility at Daresbury and marked the transition of United Kingdom (UK) nuclear physics research into a new era of international collaboration. Several talks described new international collaborative research programmes in nuclear physics initiated by UK scientists. The conference also heard of new areas of nuclear physics which will in future be opened up by high energy continuous beam electron accelerators and by radioactive ion beam accelerators. (author)

  17. Particle physics and gauge theories

    International Nuclear Information System (INIS)

    Morel, A.

    1985-01-01

    These notes are intended to help readers not familiar with particle physics in entering the domain of gauge field theory applied to the so-called standard model of strong and electroweak interactions. The introduction is considerably enlarged in order to give non specialists a general overview of present days ''elementary'' particle physics. The Glashow-Salam-Weinberg model is then treated, with the details which its unquestioned successes deserve, most probably for a long time. Finally SU(5) is presented as a prototype of these developments of particle physics which aim at a unification of all forces. Although its intrinsic theoretical difficulties and the non-observation of a sizable proton decay rate do not qualify this model as a realistic one, it has many of the properties expected from a ''good'' unified theory. In particular, it allows one to study interesting connections between particle physics and cosmology. 35 refs.

    These lectures are an introduction to the ideas of particle physics, aimed at students and teachers with little or on knowledge of the subject. They form a broad basis that will be developed in more detail by the subsequent lecturers in the school. These four lectures are meant to present an overview of particle physics based on its historical evolution over the past century. It will be shown how concepts have evolved following progress in instrumentation and in theoretical ideas, from atoms to the elementary particles and their interactions, as they are known today.

  1. Hard sell for particle physics?

    International Nuclear Information System (INIS)

    Brown, Julian.

    1994-01-01

    With particle physics experimental research becoming ever more expensive, the author considers whether the cost of such research is worthwhile. As costs escalated on the Superconducting Supercollider, the project has now been terminated. Particle physicists must now look for commercial imperatives to justify their work. Many of the important spin-offs from particle physics research are described in order to justify the subject's continued funding, albeit at very high levels, where funds might otherwise be directed to more mundane but very necessary causes such as health care or education.

    International Nuclear Information System (INIS)

    Roberts, B.A.

    1992-01-01

    Data taking for this experiment was completed in December 1983. The samples include approximately 19,000 (ν) and 11,000 (ν-bar) charged current events. These constitute the largest data set of interactions on free protons. Work published to date includes studies of inclusive structure functions and final state properties, exclusive final states, neutral current cross sections and production of strange and charmed particles. During the past year results have been published on the production of f 2 (1270) and ν 0 (770) mesons in ρp and ρ-barp charged current interactions. In the case of the f 2 this represents the first observation of such production. It is found that the multiplicities are 0.047±0.017 in ρp and 0.17±0.018 in ρ-barp. The f 2 mesons are mostly produced at large hadronic invariant mass W and in the forward hemisphere. The production of ν 0 mesons can be observed with high statistics in both ρp and ρ-barp interactions and the differential cross section studied. The observations are compared with LUND Monte Carlo predictions, which are generally found to be too high. However qualitative features of the data are reproduced. Work continues on a precise determination of the neutral current/charged current ratio, on the study of charged and neutral current structure functions and on the production of strange particles.

    Dark matter constitutes a key-problem at the interface between Particle Physics, Astrophysics and Cosmology. Indeed, the observational facts which have been accumulated in the last years on dark matter point to the existence of an amount of non-baryonic dark matter. Since the Standard Model of Particle Physics does not possess any candidate for such non-baryonic dark matter, this problem constitutes a major indication for new Physics beyond the Standard Model. We analyze the most important candidates for non-baryonic dark matter in the context of extensions of the Standard Model (in particular supersymmetric models). The recent hints for the presence of a large amount of unclustered 'vacuum' energy (cosmological constant?) is discussed from the Astrophysical and Particle Physics perspective. (author)

    The possibility of fundamental theories with very many ground states, each with different physical parameters, changes the way that we approach the major questions of particle physics. Most importantly, it raises the possibility that these different parameters could be realized in different domains in the larger universe. In this review, I survey the motivations for the multiverse and the impact of the idea of the multiverse on the search for new physics beyond the Standard Model.

  12. Elementary particle physics

    International Nuclear Information System (INIS)

    Kenyon, I.R.

    1987-01-01

    Intended for undergraduate and postgraduate students the book concentrates on the 'standard model' and the gauge symmetries. Leptons, quarks and forces are introduced at the beginning, followed by experimental techniques which have found them. Gauge theories are dealt with in order of increasing complexity - quantum electrodynamics and the gauge principle, symmetries and conservation laws, colour and quantum chromodynamics, the V - A theory of weak interactions and electroweak unification. Attention is then focussed on the hadrons. Deep inelastic scattering of hadrons is explained first, then hadron spectroscopy and then hadron interactions. Current developments beyond the Standard model - grand unification, supersymmetry, cosmology and gravitation -are discussed in the final chapter. The appendices cover kinematic, cross-section and decay-rate formulae, Breit-Wigner resonances, some Clebsch-Gordan coefficient tables, a table of particle properties, exercises and answers, and the Dirac equation. There is also an appendix on calculating scattering amplitudes for fermion + fermion going to fermion + fermion. A list of references is given. (U.K.)

  13. Ultraviolet extensions of particle physics

    DEFF Research Database (Denmark)

    Berthier, Laure Gaëlle

    The discovery of the Higgs boson in 2012 at the Large Hadron Collider completed the Standard Model field content. Many questions though remain unanswered by the Standard Model triggering a search for new physics. New physics could manifest itself at the Large Hadron Collider by the discovery of new...... particles. However, the lack of new resonances might suggest that these new particles are still out of reach which leaves us with few options. Two possibilities are explored in this thesis. The first is to study precision measurements which might indicate new physics as small deviations from the Standard...... are expressed as power series with missing higher order terms. We also show how to connect ultraviolet models of new physics to the Standard Model effective field theory and calculate bounds on them using the Standard Model effective field theory fit results. Finally, we study a nonrelativistic ultraviolet...

    Task A of this contract supports research in elementary particle physics using cryogenic particle detectors. We have developed superconducting aluminum tunnel-junction detectors sensitive to a variety of particle signals, and with potential application to a number of particle-physics problems. We have extended our range of technologies through a collaboration with Simon Labov, on niobium tri-layer junctions, and Jean-Paul Maneval, on high-T c superconducting bolometers. We have new data on response to low-energy X-rays and to alpha-particle signals from large-volume detectors. The theoretical work under this contract (Task B) is a continued investigation of nonperturbative aspects of quantum gravity. A Monte Carlo calculation is proposed for Euclidian quantum gravity, based on the ''fifth-time action'' stabilization procedure. Results from the last year include a set of seven papers, summarized below, addressing various aspects of nonperturbative quantum gravity and QCD. Among the issues- addressed is the so-called ''problem of time'' in canonical quantum gravity

The Second Edition brings the book fully up to date, including the discovery of the top quark and the search for the Higgs boson. A final short chapter is devoted to the continuing search for new physics beyond the standard model. Particle Physics, Second Edition features: * A carefully structured and written text to help students understand this exciting and demanding subject. * Many worked examples and problems to aid student learning. Hints for solving the problems are given in an Appendix. * Optional "starred" sections and appendices, containing more specialised and advanced material for the more ambitious reader.

  6. The unknowns in particles physics

    International Nuclear Information System (INIS)

    Spiro, M.

    1996-01-01

    The author presents the historical quest of particles since Democrite's time. Some particles are very difficult to identify as for instance neutrinos and antiparticles. Nine anti-hydrogen atoms have just being manufactured in the CERN. This successful result is the last episode of a long history. This achievement is the first step in the elaboration of antimatter too. The enigma of the antimatter created at the universe dawn is perennial. Why is the universe made of matter and not of antimatter? Is there any slight difference in the physical law of antimatter and matter? That's why the study of antimatter is so important. The question of the missing mass of our galaxy leads to another quest: the Higgs's particles. The graviton is another target. That could lead to the unification theory, may be another proof of the unreasonable efficiency of mathematics. (O.M.). 2 figs

We are currently engaged in construction of the MACRO detector, an Italian-American collaborative research instrument with a total particle acceptance of 10,000 m 2 sr, which will perform a sensitive search for magnetic monopoles using excitation-ionization methods. Other major objective of the MACRO experiment are to search for astrophysical high energy neutrinos expected to be emitted by such objects as Vela X-1, LMC X-4 and SN-1987A and to search for low energy neutrino bursts from gravitational stellar collapse. We are also working on BOREX, a liquid scintillation solar neutrino experiment and GRANDE, a proposed very large area surface detector for astrophysical neutrinos, and on the development of new techniques for liquid scintillation detection

    CERN Document Server

    Paetz gen Schieck, Hans

    2012-01-01

    The measurement of spin-polarization observables in reactions of nuclei and particles is of great utility and advantage when the effects of single-spin sub-states are to be investigated. Indeed, the unpolarized differential cross-section encompasses the averaging over the spin states of the particles, and thus loses details of the interaction process. This introductory text combines, in a single volume, course-based lecture notes on spin physics and on polarized-ion sources with the aim of providing a concise yet self-contained starting point for newcomers to the field, as well as for lecturers in search of suitable material for their courses and seminars. A significant part of the book is devoted to introducing the formal theory-a description of polarization and of nuclear reactions with polarized particles. The remainder of the text describes the physical basis of methods and devices necessary to perform experiments with polarized particles and to measure polarization and polarization effects in nuclear rea...

    Attributing keywords can assist in the classification and retrieval of documents in the particle physics literature. As information services face a future with less available manpower and more and more documents being written, the possibility of keyword attribution being assisted by automatic classification software is explored. A project being carried out at CERN (the European Laboratory for Particle Physics) for the development and integration of automatic keywording is described.

    Massive neutrinos reveal physics beyond the Standard Model, which could have deep consequences for our understanding of the Universe. Their study should therefore receive the highest level of priority in the European Strategy. The discovery and study of leptonic CP violation and precision studies of the transitions between neutrino flavours require high intensity, high precision, long baseline accelerator neutrino experiments. The community of European neutrino physicists involved in oscillation experiments is strong enough to support a major neutrino long baseline project in Europe, and has an ambitious, competitive and coherent vision to propose. Following the 2006 European Strategy for Particle Physics (ESPP) recommendations, two complementary design studies have been carried out: LAGUNA/LBNO, focused on deep underground detector sites, and EUROnu, focused on high intensity neutrino facilities. LAGUNA LBNO recommends, as first step, a conventional neutrino beam CN2PY from a CERN SPS North Area Neutrino Fac...

  6. Particle physics with cold neutrons

    International Nuclear Information System (INIS)

    Dubbers, D.

    1991-01-01

    Slow neutrons are used in a large number of experiments to study the physics of particles and their fundamental interactions. Some of these experiments search for manifestations of ''new physics'' like baryon- or lepton-number nonconservation, time reversal nonconservation, new particles, right-handed currents, nonzero neutron charge, nonlinear terms in the Schrodinger equation, exotic e + e - states, and others. Other slow neutron experiments test the present Standard Model. The parity nonconserving weak neutron-nucleon interaction is studied in a variety of experiments. Free neutron beta decay gives precise values for the weak vector and axialvector coupling constants, which allow precise tests of basic symmetries like the conservation of the weak vector current, the unitarity of the weak quark mixing matrix, SU(3) flavour symmetry, and right-handed currents. Neutron beta decay data are further needed to calculate weak cross-sections, for applications, in big bang cosmology, in astrophysics, in solar physics and the solar neutrino problem, and in such mundane things as neutrino detection efficiencies in neutrino oscillation or proton decay experiments. Neutron-nucleon, neutron-nucleus and neutron-electron scattering lengths are determined in high precision experiments, which use methods like neutron interferometry or neutron gravity spectrometry. The experiments give information on quantities like the neutron charge radius or the neutron electric polarizability. Precision measurements of other fundamental constants lead to a better, model-independent value of the fine structure constant. Finally, the fundamental experiments on quantum mechanics, like spinor 4π -rotation, Berry's phase, dressed neutrons, Aharanov - Casher effect, or gravitational effects on the neutron's phase will be briefly discussed.

  7. Physical Origin of Elementary Particle Masses

    2014-01-01

    In contemporary particle physics, the masses of fundamental particles are incalculable constants, being supplied by experimental values. Inspired by observation of the empirical particle mass spectrum, and their corresponding physical interaction couplings, we propose that the masses of elementary particles arise solely due to the self-interaction of the fields associated with the charges of a particle. A first application of this idea is seen to yield correct order of magnitude predictions f...

  8. Elementary particle physics with atoms

    International Nuclear Information System (INIS)

    Wieman, C.E.

    1993-01-01

    One of the unique aspects of atomic physics is the capacity to make measurements with extraordinarily high precision. In suitably chosen systems, precision measurements can reveal information about fundamental interactions in nature that is not available from other sources. Although elementary particle physics is often perceived as synonymous with open-quotes high energyclose quotes and open-quotes high cost,close quotes atomic physics has played, and can continue to play, a significant role in this area. A few illustrative examples of this include (1) the measurement of the Lamb shift in hydrogen and its, influence on the modern development of quantum field theory, (2) the severe limits placed on possible time reversal violating interactions by atomic (and neutron) searches for electric dipole moments, and (3) the measurement (and closely related atomic theory) of parity, nonconservation in atoms. This latter work has provides a precise confirmation of the Standard Model of the weak, electromagnetic, and strong interactions, and is a uniquely sensitive test for the validity of a variety of alternative models that have been put forth. I will also discuss some of the joys and frustrations of doggedly pursuing the open-quotes ultimateclose quotes measurement of ridiculously tiny effects

    Various information retrieval systems for elementary particle physics are introduced. Scientific information has been distributed in the form of books, periodicals or preprints. Some periodicals include the abstracts of information only. Recently, computer systems, by which the information retrieval can be easily done, have been developed. The construction of networks connecting various computer systems is in progress. It is possible to call the data base of Rutherford Laboratory from a telephone terminal of Laurence Berkeley Laboratory. The access to the Network by British Science Research Council can be made from DESY or CERN. The examples of on-line information retrieval in Japan are presented. Some of the periodicals of secondary information and data books are also introduced. (Kato, T.)

  12. Particle identification for beauty physics

    International Nuclear Information System (INIS)

    Ludlam, T.

    1987-01-01

    We look briefly at the requirements for particle identification for possible beauty experiments at the Tevatron, both in the fixed target and the collider mode. Techniques presently in use in high energy physics experiments, and under development, should make sensitive experiments feasible. However, in all cases the present state of the art must be advanced to meet the necessary requirements for segmentation andor rate capability. The most fundamentally difficult challenges appear to be the efficient tagging of soft electrons (for the collider experiment) and the need to handle interaction rates up to /approximately/ 10 9 HZ in the fixed target mode. In both cases we can find ''in principle'' demonstrations that the requirements can be met. We have considered only the most basic prooperties of detectors, however, and the real answers will come from careful studies of details. 20 refs., 10 figs

  1. Elementary particle physics---Experimental

    International Nuclear Information System (INIS)

    Lord, J.J.; Burnett, T.H.; Wilkes, R.J.

    1990-01-01

    We are continuing a research program in high energy experimental particle physics and particle astrophysics. Studies of high energy hadronic interactions were performed using several techniques, in addition, a high energy leptoproduction experiment was continued at the Fermi National Accelerator Laboratory. We are participants in a joint US/Japan program to study nuclear interactions at energies two orders of magnitude greater than those of existing accelerators. The data are being collected with ballon-borne emulsion chambers. The properties of nuclear interactions at these high energies will reveal whether new production mechanisms come into play due to the high nuclear densities and temperatures obtained. We carried out closely related studies of hadronic interactions in emulsions exposed to high energy accelerator beams. We are members of a large international collaboration which has exposed emulsion chamber detectors to beams of 32 S and 16 O with energy 60 and 200 GeV/n at CERN and 15 GeV/n at Brookhaven National Laboratory. The primary objectives of this program are to determine the existence and properties of the hypothesized quark-gluon phase of matter, and its possible relation to a variety of anomalous observations. Studies of leptoproduction processes at high energies involve two separate experiments, one using the Tevatron 500 GeV muon beam and the other exploring the >TeV regime. We are participants in Fermilab experiment E665 employing a comprehensive counter/streamer chamber detector system. During the past year we joined the DUMAND Collaboration, and have been assigned responsibility for development and construction of critical components for the deep undersea neutrino detector facility, to be deployed in 1991. In addition, we are making significant contributions to the design of the triggering system to be used

  2. Matter and Interactions: a particle physics perspective

    OpenAIRE

    Organtini, Giovanni

    2011-01-01

    In classical mechanics matter and fields are completely separated. Matter interacts with fields. For particle physicists this is not the case. Both matter and fields are represented by particles. Fundamental interactions are mediated by particles exchanged between matter particles. In this paper we explain why particle physicists believe in such a picture, introducing the technique of Feynman diagrams starting from very basic and popular analogies with classical mechanics, making the physics ...

  3. Studies in theoretical particle physics

    International Nuclear Information System (INIS)

    Kaplan, D.B.

    1991-01-01

    This proposal focuses on research on three distinct areas of particle physics: (1) Nonperturbative QCD. I tend to continue work on analytic modelling of nonperturbative effects in the strong interactions. I have been investigating the theoretical connection between the nonrelativistic quark model and QCD. The primary motivation has been to understand the experimental observation of nonzero matrix elements involving current strange quarks in ordinary matter -- which in the quark model has no strange quark component. This has led to my present work on understanding constituent (quark model) quarks as collective excitations of QCD degrees of freedom. (2) Weak Scale Baryogenesis. A continuation of work on baryogenesis in the early universe from weak interactions. In particular, an investigation of baryogenesis occurring during the weak phase transition through anomalous baryon violating processes in the standard model of weak interactions. (3) Flavor and Compositeness. Further investigation of a new mechanism that I recently discovered for dynamical mass generation for fermions, which naturally leads to a family hierarchy structure. A discussion of recent past work is found in the next section, followed by an outline of the proposed research. A recent publication from each of these three areas is attached to this proposal

    This is the LaTeX version of my book "Particle Physics and Inflationary Cosmology'' (Harwood, Chur, Switzerland, 1990). I decided to put it to hep-th, to make it easily available. Many things happened during the 15 years since the time when it was written. In particular, we have learned a lot about the high temperature behavior in the electroweak theory and about baryogenesis. A discovery of the acceleration of the universe has changed the way we are thinking about the problem of the vacuum energy: Instead of trying to explain why it is zero, we are trying to understand why it is anomalously small. Recent cosmological observations have shown that the universe is flat, or almost exactly flat, and confirmed many other predictions of inflationary theory. Many new versions of this theory have been developed, including hybrid inflation and inflationary models based on string theory. There was a substantial progress in the theory of reheating of the universe after inflation, and in the theory of eternal inflation. ...

    You may remember noticing a pop-up Big Bang on your way to Restaurant No. 1 last November, as part of the Library’s book fair. This was just one page from a rather original project to make a pop-up book about particle physics. The book – Voyage to the Heart of Matter, the ATLAS experiment at CERN - will be launched in the USA and Canada, in a new silver edition.   The book proved a popular Christmas gift in the UK when it was released last November - copies on sale there sold out in under two months. The new print run will go on sale in Australia and the UK, in addition to Canada and the US. It will be launched to the press during the week of the New York book fair and will befollowed by a public event at the New York Academy of Sciences on 25 May. You can purchase a copy at the ATLAS secretariat, the Library or the Building 33 shop for 30CHF. For more information about the launch event, see http://www.nyas.org/ATLAS.

  7. Topics in elementary particle physics

    Science.gov (United States)

    Jin, Xiang

    The author of this thesis discusses two topics in elementary particle physics: n-ary algebras and their applications to M-theory (Part I), and functional evolution and Renormalization Group flows (Part II). In part I, Lie algebra is extended to four different n-ary algebraic structure: generalized Lie algebra, Filippov algebra, Nambu algebra and Nambu-Poisson tensor; though there are still many other n-ary algebras. A natural property of Generalized Lie algebras — the Bremner identity, is studied, and proved with a totally different method from its original version. We extend Bremner identity to n-bracket cases, where n is an arbitrary odd integer. Filippov algebras do not focus on associativity, and are defined by the Fundamental identity. We add associativity to Filippov algebras, and give examples of how to construct Filippov algebras from su(2), bosonic oscillator, Virasoro algebra. We try to include fermionic charges into the ternary Virasoro-Witt algebra, but the attempt fails because fermionic charges keep generating new charges that make the algebra not closed. We also study the Bremner identity restriction on Nambu algebras and Nambu-Poisson tensors. So far, the only example 3-algebra being used in physics is the BLG model with 3-algebra A4, describing two M2-branes interactions. Its extension with Nambu algebra, BLG-NB model, is believed to describe infinite M2-branes condensation. Also, there is another propose for M2-brane interactions, the ABJM model, which is constructed by ordinary Lie algebra. We compare the symmetry properties between them, and discuss the possible approaches to include these three models into a grand unification theory. In Part II, we give an approximate solution for Schroeder's equations, based on series and conjugation methods. We use the logistic map as an example, and demonstrate that this approximate solution converges to known analytical solutions around the fixed point, around which the approximate solution is constructed

    CERN is the world's largest particle physics research laboratory. Since it was established in 1954, it has made an outstanding contribution to our understanding of the fundamental particles and their interactions, and also to the technologies needed to analyse their properties and behaviour. The experimental challenges have pushed the performance of particle accelerators and detectors to the limits of our technical capabilities, and these groundbreaking technologies can also have a significant impact in applications beyond particle physics. In particular, the detectors developed for particle physics have led to improved techniques for medical imaging, while accelerator technologies lie at the heart of the irradiation methods that are widely used for treating cancer. Indeed, many important diagnostic and therapeutic techniques used by healthcare professionals are based either on basic physics principles or the technologies developed to carry out physics research.

  10. Plasma physics via particle simulation

    International Nuclear Information System (INIS)

    Birdsall, C.K.

    1981-01-01

    Plasmas are studied by following the motion of many particles in applied and self fields, analytically, experimentally and computationally. Plasmas for magnetic fusion energy devices are very hot, nearly collisionless and magnetized, with scale lengths of many ion gyroradii and Debye lengths. The analytic studies of such plasmas are very difficult as the plasma is nonuniform, anisotropic and nonlinear. The experimental studies have become very expensive in time and money, as the size, density and temperature approach fusion reactor values. Computational studies using many particles and/or fluids have complemented both theories and experiments for many years and have progressed to fully three dimensional electromagnetic models, albeit with hours of running times on the fastest largest computers. Particle simulation methods are presented in some detail, showing particle advance from acceleration to velocity to position, followed by calculation of the fields from charge and current densities and then further particle advance, and so on. Limitations due to the time stepping and use of a spatial grid are given, to avoid inaccuracies and instabilities. Examples are given for an electrostatic program in one dimension of an orbit averaging program, and for a three dimensional electromagnetic program. Applications of particle simulations of plasmas in magnetic and inertial fusion devices continue to grow, as well as to plasmas and beams in peripheral devices, such as sources, accelerators, and converters.

  11. For a European physics of particles

    Baruch, J.O.; Aymar, R.

    2004-01-01

    This article reports an interview of R. Aymar the present head of the CERN since the first of january 2004. R.Aymar presents the progress made concerning different objectives of the CERN: 1) in summer 2007 the LHC (large hadron collider) will be operating, 2) the beam of neutrinos that will depart from CERN to reach Italy in order to be analysed in the Gran-Sasso tunnel will be running in 2006 as scheduled, 3) new projects: the feasibility studies of the CLIC (a compact linear collider that might reach 4 to 5 TeV) have to be more supported in order to get a clear answer on the feasibility by 2009. In this interview other topics such as the world-wide extension of the CERN (New-Zealand is a contributor to LHC) or the state of fundamental research in France are also tackled. (A.C.)

  12. Astro particle physics view on supersymmetry

    The particle physics interpretation of the missing-mass, or dark-matter, problem of cosmological and astrophysical nature is going to be posed under deep scrutiny in the next years. From the particle physics side, accelerator physics will deeply test theoretical ideas of new physics beyond the Standard Model, where a particle physics candidate to dark matter is often naturally obtained. From the astrophysical side, many probes are already providing a great deal of independent information on the signals which can be produced by the galactic or extra-galactic dark matter. The ultimate hope is in fact to be able to disentangle a dark matter signal from the various sources of backgrounds and to extract a coherent picture of new physics from the accelerator physics, astrophysics and cosmology side. A very ambitious and far-reaching project, indeed.

    CERN is the world's largest particle physics research laboratory. Since it was established in 1954, it has made an outstanding contribution to our understanding of the fundamental particles and their interactions, and also to the technologies needed to analyse their properties and behaviour. The experimental challenges have pushed the performance of particle accelerators and detectors to the limits of our technical capabilities, and these groundbreaking technologies can also have a significant impact in applications beyond particle physics. In particular, the detectors developed for particle physics have led to improved techniques for medical imaging, while accelerator technologies lie at the heart of the irradiation methods that are widely used for treating cancer. Indeed, many important diagnostic and therapeutic techniques used by healthcare professionals are based either on basic physics principles or the technologies developed to carry out physics research. Ever since the discovery of x-rays by Roentgen in 1895, physics has been instrumental in the development of technologies in the biomedical domain, including the use of ionizing radiation for medical imaging and therapy. Some key examples that are explored in detail in this book include scanners based on positron emission tomography, as well as radiation therapy for cancer treatment. Even the collaborative model of particle physics is proving to be effective in catalysing multidisciplinary research for medical applications, ensuring that pioneering physics research is exploited for the benefit of all.

  20. USA lays out strategic vision for particle physics

    CERN Multimedia

    2014-01-01

    Yesterday saw the publication of the latest P5 report in the United States. Shorthand for Particle Physics Project Prioritisation Panel, the P5 report is the US equivalent of the European Strategy update that was published last year, and it’s good to see that the two reports present a common vision of the direction our field should take over the coming years.   P5 was charged with developing a 10-year plan for US particle physics, identifying compelling scientific opportunities. Its approach was similar to the European one, based on a broad consultation among the particle physics community. For the energy frontier, the report is clear. The LHC will be the focus for the US particle physics community for the immediate and short-term future. The report goes on to lay out a bold vision for development of a unique world-class neutrino programme in the US, with the long-term focus being a reformulated Long Baseline Neutrino Facility (LBNF) hosted at Fermilab. This is a very positive deve...

    Melissinos, Adrian

    2013-01-01

    A personal recount in areas of particle physics and related fields as a research physicist for over 50 years, Adrian Melissinos' insights into the ways that general research was carried out, as well as the evolution of particle physics from 1958 to 2008 will prove valuable to science history enthusiasts, as well as particle physicists. Be it conventional accelerator experiments, the use of microwave techniques in search of cosmic axions, or taking advantage of high power lasers to observe light-by-light scattering, the excitement of searching for something new in the face of failures and then successes is enriching, and the collaboration with gifted and outstanding colleagues and students proves insightful. A hybrid of personal reminiscences and a professional journey, readers get to relive the joy and excitement of researching and teaching in small groups during those early years while gaining a partial historical perspective of particle physics since 1958 - all in "Reminiscences: A Journey through Particle ...

    The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as heavy neutrinos, supersymmetric and technicolor particles, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as Supersymmetry, Extra Dimensions, Particle Detectors, Probability, and Statistics. Among the 112 reviews are many that are new or heavily revised including those on: Dark Energy, Higgs Boson Physics, Electroweak Model, Neutrino Cross Section Measurements, Monte Carlo Neutrino Generators, Top Quark, Dark Matter, Dynamical Electroweak Symmetry Breaking, Accelerator Physics of Colliders, High-Energy Collider Parameters, Big Bang Nucleosyn...

    participants, and finally basic and astrophysical plasmas (BAP). New strategies are required to achieve a more balanced participation of these four areas of knowledge in future meetings, but the large number of participants and the overall high quality of the invited talks were particularly relevant this year. In the preparation of the Conference Programme we tried to present an updated view of plasma physics and to integrate suggestions coming from the scientific community, in particular through the use of the EPS PPD Open Forum. As mentioned, two evening sessions took place during the Conference. This year, the traditional evening on ITER was replaced by a session dedicated to inertial fusion, organized by D Batani, where the main installations and experiments on laser fusion around the world were presented and critically discussed. The other session, dedicated to plasma physics education, was organized by N Lopes-Cardoso, and discussed the specific educational issues of plasma physics and fusion, and presented the training programmes existing in Europe. As a concluding remark, we would like to thank our colleagues of the Programme Committee and, in particular, the coordinators of the subcommittees, Clarisse Bourdelle and Arthur Peters for MCF, Javier Honrubia for BPIF, Christoph Hollenstein for LTP, and Uli Stroth for BAP, for their generous help, suggestions and support. Due to the large number of participants, the smooth and efficient local organization, and the high overall quality of the plenary and invited presentations, the 37th EPS Conference on Plasma Physics can be considered an undeniable success. I hope you will find, in this special issue of Plasma Physics and Controlled Fusion, an interesting and useful account of this event. Outstanding scientists honoured at the 37th European Physical Society Conference on Plasma Physics During the Conference the EPS Plasma Physics Division rewarded researchers who have achieved outstanding scientific or technological results

    The EMODnet-Physics portal (www.emodnet-physics.eu) makes layers of physical data and their metadata available for use and contributes towards the definition of an operational European Marine Observation and Data Network (EMODnet). It is based on a strong collaboration between EuroGOOS associates and its regional operational systems (ROOSs), and it is bringing together two very different marine communities: the "real time" ocean observing institute/centers and the National Oceanographic Data Centres (NODCs) that are in charge of ocean data validation, quality check and update for marine environmental monitoring. The EMODnet-Physics is a Marine Observation and Data Information System that provides a single point of access to near real time and historical achieved data (www.emodnet-physics.eu/map) it is built on existing infrastructure by adding value and avoiding any unless complexity, it provides data access to users, it is aimed at attracting new data holders, better and more data. With a long-term vision for a pan European Ocean Observation System sustainability, the EMODnet-Physics is supporting the coordination of the EuroGOOS Regional components and the empowerment and improvement of their data management infrastructure. In turn, EMODnet-Physics already implemented high-level interoperability features (WMS, Web catalogue, web services, etc…) to facilitate connection and data exchange with the ROOS and the Institutes within the ROOSs (www.emodnet-physics.eu/services). The on-going EMODnet-Physics structure delivers environmental marine physical data from the whole Europe (wave height and period, temperature of the water column, wind speed and direction, salinity of the water column, horizontal velocity of the water column, light attenuation, and sea level) as monitored by fixed stations, ARGO floats, drifting buoys, gliders, and ferry-boxes. It does provide discovering of data sets (both NRT - near real time - and Historical data sets), visualization and free

    1988-09-01

    With the advent of the standard model of quarks, leptons and unified forces one has achieved an understanding of the wealth of data in particle physics and provided a new basis for the understanding of nuclei and hadrons. In particle physics one now seeks to improve the standard model and to go beyond it. In nuclear physics one enquires about the role of quarks and gluons in the dynamics of strongly interacting systems. To answer these new questions an impressive network of large accelerator facilities, including CEBAF, is under construction or in the proposal stage. A global view of this network and its physics is given. (Author) (3 figs.)

    International Nuclear Information System (INIS)

    Dover, C.B.

    1988-01-01

    Recent progress in the understanding of strange particle interactions with nuclear systems is reviewed. We discuss the relative merits of various reactions such as (K - , π/sup +-/), (π + , K + ), or (γ, K + ) for hypernuclear production. The structure of /sub Λ/ 13 C is analyzed in some detail, in order to illustrate the role of the ΛN residual interaction and approximate dynamical symmetries in hypernuclear structure. Recent results on the single particle states of a Λ in heavy systems, as revealed by (π + , K + ) reaction studies, are used to extract information on the density dependence and effective mass which characterize the Λ-nucleus mean field. Finally, we develop the idea the K + -nucleus scattering at low energies is sensitive to the subtle ''swelling'' effects for nucleons bound in nuclei. 64 refs., 13 figs

    What really happens at the most fundamental levels of nature? Introducing Particle Physics explores the very frontiers of our knowledge, even showing how particle physicists are now using theory and experiment to probe our very concept of what is real. From the earliest history of the atomic theory through to supersymmetry, micro-black holes, dark matter, the Higgs boson, and the possibly mythical graviton, practising physicist and CERN contributor Tom Whyntie gives us a mind-expanding tour of cutting-edge science. Featuring brilliant illustrations from Oliver Pugh, Introducing Particle Physics is a unique tour through the most astonishing and challenging science being undertaken today.

    Schrempp, F.

    1985-01-01

    In a first part, I review the general theoretical arguments leading to new physics and new particles beyond the Standard Model, either in terms of supersymmetry or compositeness. Speculations about new particles expected within these schemes are then discussed in the light of recent anomalous events from the panti p collider and from PETRA. In a second part, I specifically try to evaluate the potential of γγ and epsilonγ collisions at PETRA/PEP and LEP energies with respect to new particle searches. Some interesting possibilities, including searches for spinless composite bosons, non-standard enhanced Higgs particles, scalar electrons (e) and γγ ->'nothing' emerge. (orig.)

  4. Gauge theories in particle physics

    International Nuclear Information System (INIS)

    Aitchison, I.J.R.; Hey, A.J.G.

    1982-01-01

    The first theory, quantum electrodynamics (QED) is known to give a successful account of electromagnetic interactions. Weak and strong interactions are described by gauge theories which are generalisations of QED. The electro-weak gauge theory of Glashow Salam and Weinberg unites electromagnetic and weak interactions. Quantum chromodynamics (QCD) is the gauge theory of strong interactions. This approach to these theories, designed for the non-specialist, is based on a straightforward generalisation of non-relativistic quantum-mechanical perturbation theory to the relativistic case, leading to an intuitive introduction to Feynman graphs. Spontaneously broken-or 'hidden'-symmetries are given particular attention, with the physics of hidden gauge invariance and the role of the vacuum (essential to the unified theories) being illustrated by an extended but elementary discussion of the non-relativistic example of superconductivity. Throughout, emphasis is placed both on realistic calculations and on physical understanding. (author)

    The answer to the question in the title is: in search of new physics beyond the Standard Model, for which there are many motivations, including the likely instability of the electroweak vacuum, dark matter, the origin of matter, the masses of neutrinos, the naturalness of the hierarchy of mass scales, cosmological inflation and the search for quantum gravity. So far, however, there are no clear indications about the theoretical solutions to these problems, nor the experimental strategies to resolve them. It makes sense now to prepare various projects for possible future accelerators, so as to be ready for decisions when the physics outlook becomes clearer. Paraphrasing George Harrison, “If you don’t yet know where you’re going, any road may take you there.”

  7. Particle Physics at the LHC Start

    Altarelli, Guido

    2011-01-01

    I present a concise review of the major issues and challenges in particle physics at the start of the LHC era. After a brief overview of the Standard Model and of QCD, I will focus on the electroweak symmetry breaking problem which plays a central role in particle physics today. The Higgs sector of the minimal Standard Model is so far just a mere conjecture that needs to be verified or discarded by the LHC. Probably the reality is more complicated. I will summarize the motivation for new physics that should accompany or even replace the Higgs discovery and a number of its possible forms that could be revealed by the LHC.

    Masiero, A.; Senjanovic, G.; Smirnov, A.Yu.; Thompson, G.

    2002-01-01

    The aim of this school was to give a panoramic view on the field of particle physics with its achievements and problems, successes and failures. The standard model of the electroweak and strong interactions is in perfect shape. Physics of the standard model and its precision tests have been extensively discussed during the school. What is next? Do we have a 'standard model' of physics beyond the standard model? In this connection the status of low scale supersymmetry, supersymmetric Grand Unification and various flavor symmetries has been presented. Discovery of neutrino masses and mixing is probably the first experimental manifestation of new physics. Do we have a viable alternative of the (TeV scale) SUSY and GUT? Models with large, or infinite, or wrapped extra dimensions, the bulk-brane scenarios (widely discussed in series of lectures) may give some answers to this question. Is non-commutative field theory relevant for particle physics? Are the tools we have at hand enough to solve problems of particle physics? Is something fundamentally important missed in our approaches? These, and many other questions, were among the hot topics of the school. In this volume we publish four courses of lectures given by leading experts in the fields which represent two main areas of the research mentioned above: Physics of the standard model and Physics beyond the standard model. Both basic and advanced topics are presented in the lectures on nonperturbative QCD and quark-gluon plasma. First results from heavy ion collider RHIC are discussed. Important recent progress in particle physics is related to operation of the B-factories. This subject is covered in lectures on B-physics and CP-violation. Physics beyond the standard model is represented by lectures on Grand Unification with emphasis on explanation of fermion masses, in particular neutrino masses and mixing, and on predictions for proton decay. Another course is devoted to the fascinating subject: physics of non

    The Astroparticle Physics European Consortium (APPEC) invites you to a town meeting at the Grand Amphithéatre de Sorbonne in Paris on the 6th and 7th April 2016 to discuss an update of the 2011 APPEC Astroparticle Physics roadmap, to be published in September 2016. In 2014 APPEC decided to launch an update of the 2011 Roadmap, transforming it to a “resource aware” roadmap. The intention was to gauge the financial impact of the beginnings of operation of the large global scale observatories put forward in the previous roadmap and to examine the possibilities of international coordination of future global initiatives. The APPEC Scientific Advisory Committee examined the field and prepared a set of recommendations. Based on these recommendations, the APPEC General Assembly drafted a set of “considerations” to be published by end of February 2016 and be debated in an open dialogue with the community, through the web page but primarily at the town meeting of 6-7 April. Based on this debate the final re...

  17. Topics in particle physics phenomenology

    International Nuclear Information System (INIS)

    Pantaleone, J.T.

    1985-01-01

    This thesis consists of topics in field theory. In part A: (Chapter 1) A short review of heavy-quark physics, (Chapter 2) Spin-dependent forces in heavy-quark systems, (Chapter 3) Bound state effects in the Upsilon → γ + resonance, and in part B, The compatibility of free fractional charge and Dirac magnetic monopoles. In Chapter 2, using the results of the fourth-order quark-antiquark interactions in perturbative QCD, we show that the spin-dependent potentials in the formalism of Eichten and Feinberg and Gromes have to be generalized to include the quark mass dependence. The recently observed hyperfine and fine structure splittings in the J/psi and Upsilon systems are found to agree with the purely perturbative QCD results for the scale parameter Λ/sub MS/ = 0.30 +/- 0.06 GeV. With this value for Λ/sub MS/ we give some predictions on the T and toponium spectroscopies. In Chapter 3 we study the effect of b anti b bound state dynamics on the reaction Upsilon → γ + resonance. We argue from the results that the recently discovered sigma (8320) must have a scalar, rather than a pseudoscalar, coupling to the b quark

  18. Flavor Democracy in Particle Physics

    International Nuclear Information System (INIS)

    Sultansoy, Saleh

    2007-01-01

    The flavor democracy hypothesis (or, in other words, democratic mass matrix approach) was introduced in seventies taking in mind three Standard Model (SM) families. Later, this idea was disfavored by the large value of the t-quark mass. In nineties the hypothesis was revisited assuming that extra SM families exist. According to flavor democracy the fourth SM family should exist and there are serious arguments disfavoring the fifth SM family. The fourth SM family quarks lead to essential enhancement of the Higgs boson production cross-section at hadron colliders and the Tevatron can discover the Higgs boson before the LHC, if it mass is between 140 and 200 GeV. Then, one can handle 'massless' Dirac neutrinos without see-saw mechanism. Concerning BSM physics, flavor democracy leads to several consequences: tanβ ≅ mt/mb ≅ 40 if there are three MSSM families; super-partner of the right-handed neutrino can be the LSP; relatively light E(6)-inspired isosinglet quark etc. Finally, flavor democracy may give opportunity to handle ''massless'' composite objects within preonic models

    This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2658 new measurements from 644 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. Among the 112 reviews are many that are new or heavily revised including those on Heavy-Quark and Soft-Collinear Effective Theory, Neutrino Cross Section Measurements, Monte Carlo Event Generators, Lattice QCD, Heavy Quarkonium Spectroscopy, Top Quark, Dark Matter, Vcb & Vub, Quantum Chromodynamics, High-Energy Collider Parameters, Astrophysical Constants, Cosmological Parameters, and Dark Matter.

    The CMS Masterclass enables high school students to analyse authentic CMS data. Students can draw conclusions on key ratios and particle masses by combining their analyses. In particular, they can use the ratio of W^+ to W^- candidates to probe the structure of the proton, they can find the mass of the Z boson, and they can identify additional particles including, tentatively, the Higgs boson. In the United States, masterclasses are part of QuarkNet, a long-term program that enables students and teachers to use cosmic ray and particle physics data for learning with an emphasis on data from CMS.

    Barr, Giles; Walczak, Roman; Weidberg, Tony

    2016-01-01

    This text gives an introduction to particle physics at a level accessible to advanced undergraduate students. It is based on lectures given to 4th year physics students over a number of years, and reflects the feedback from the students. The aim is to explain the theoretical and experimental basis of the Standard Model (SM) of Particle Physics with the simplest mathematical treatment possible. All the experimental discoveries that led to the understanding of the SM relied on particle detectors and most of them required advanced particle accelerators. A unique feature of this book is that it gives a serious introduction to the fundamental accelerator and detector physics, which is currently only available in advanced graduate textbooks. The mathematical tools that are required such as group theory are covered in one chapter. A modern treatment of the Dirac equation is given in which the free particle Dirac equation is seen as being equivalent to the Lorentz transformation. The idea of generating the SM interac...

  7. Particle Physics in the LHC Era

    CERN Document Server

    Bunk, Don

    During the past 100 years experimental particle physicists have collected an impressive amount of data. Theorists have also come to understand this data extremely well. It was in the first half of the 20th century the efforts of the early pioneers of quantum mechanics laid the ground work for this understanding: quantum field theory. Through the tireless efforts of researchers during the later half of the 20th century many ideas came together to form what we now call the Standard Model (SM) of particle physics. Finally, it was through the ideas of the renormalization group and effective field theory that the understanding of how the SM fits into a larger framework of particle physics was crystallized. In the past four years the Large Hadron Collider (LHC) has made more precise measurements than ever before. Currently the SM of particle physics is known to have excellent agreement with these measurements. As a result of this agreement with data, the SM continues to play such a central role in modern particle p...

  12. Constraints on particle physics from cosmology

    International Nuclear Information System (INIS)

    Schramm, D.N.; Charlton, J.C.

    1986-01-01

    Cosmology and particle physics have become symbiotic in their relationship. In the past, developments in physics have been used to explain astrophysics problems. Recently, cosmology also has been able to place constraints on particle properties and these constraints can be tested by experiment. Thus, the flow of information at the interface of particle physics and cosmology is no longer just one-way. (Astronomy is no longer a parasite of physics.) Many examples of the interchange are described in this review. The timeline of cosmology is rapidly filling in as later events find their explanations in earlier events. In this review, the authors mention what is known about each epoch and show how it might constrain the particle models. Since a great deal of effort is devoted currently to the study of the dark matter problem, special emphasis will be placed on this issue. This study of dark matter and galaxy formation will allow us to draw upon much of what was discussed in earlier epochs. This review draws heavily on a previous review by the authors

  4. Particle physics 2009: licence to smile

    CERN Multimedia

    2009-01-01

    Julie Peasley is the keeper of a very unusual zoo, a colourful set of hand-made plushies that represent the particles of the Standard Model and beyond. Her passion for physics and her art degree combine to give particles their personalities. She visited CERN on 25 May and met the CERNois in the library. Scientists consider that they have ‘seen’ a particle when their detectors send an electronic signal and a spot appears on their computer screen. The American artist Julie Peasley has gone much further than that and has started sewing toys so that we can not just ‘see’ what particles look like but even play with them! "When I started," says Julie, "my plushies weren’t smiling, they were just a face. Later on, I realised that I wanted them to all be happy and to appear like they are having fun. Except for the neutron, which insists on remaining ne...

  5. Updating Europe’s strategy for particle physics

    CERN Multimedia

    2012-01-01

    These have been an important two weeks for particle physics in Europe and at CERN. From 10-12 September, some 500 physicists went to Krakow to discuss their wishes for the future of the field as input to the CERN Council’s strategy group.   The strategy group is tasked with updating the European Strategy for Particle Physics adopted by Council in 2006, taking into account developments in the field over the last six years. Discussions were wide ranging, and included input from the Americas and Asia. These were particularly important, since it’s vital for the field that Europe’s strategy is in synch with what’s happening elsewhere in the world. I hardly need to tell you that the years since 2006 have seen monumental changes in particle physics, notably the discovery by ATLAS and CMS of a particle consistent with the Higgs boson. But it’s not only the high-energy frontier of the LHC that has provided new results. There have been important advanc...

    2004-12-01

    This special issue of Plasma Physics and Controlled Fusion comprises refereed papers contributed by invited speakers at the 31st European Physical Society Conference on Plasma Physics. The conference was jointly hosted by the Rutherford Appleton Laboratory, by the EURATOM/UKAEA Fusion Association and by Imperial College London, where it took place from 28 June to 2 July 2004. The overall agenda for this conference was set by the Board of the Plasma Physics Division of the European Physical Society, chaired by Friedrich Wagner (MPIPP, Garching) and his successor Jo Lister (CRPP, Lausanne). It built on developments in recent years, by further increasing the scientific diversity of the conference programme, whilst maintaining its depth and quality. A correspondingly diverse Programme Committee was set up, whose members are listed below. The final task of the Programme Committee has been the preparation of this special issue. In carrying out this work, as in preparing the scientific programme of the conference, the Programme Committee formed specialist subcommittees representing the different fields of plasma science. The chairmen of these subcommittees, in particular, accepted a very heavy workload on behalf of their respective research communities. It is a great pleasure to take this opportunity to thank: Emilia R Solano (CIEMAT, Madrid), magnetic confinement fusion; Jürgen Meyer-ter-Vehn (MPQ, Garching), laser-plasma interaction and beam plasma physics; and Jean-Luc Dorier (CRPP, Lausanne), dusty plasmas. The relatively few papers in astrophysical and basic plasma physics were co-ordinated by a small subcommittee which I led. Together with Peter Norreys (RAL, Chilton), we five constitute the editorial team for this special issue. The extensive refereeing load, compressed into a short time interval, was borne by the Programme Committee members and by many other experts, to whom this special issue owes much. We are also grateful to the Local Organizing Committee

  10. Semiconductor detectors in nuclear and particle physics

    International Nuclear Information System (INIS)

    Rehak, P.; Gatti, E.

    1995-01-01

    Semiconductor detectors for elementary particle physics and nuclear physics in the energy range above 1 GeV are briefly reviewed. In these two fields semiconductor detectors are used mainly for the precise position sensing. In a typical experiment, the position of a fast charged particle crossing a relatively thin semiconductor detector is measured. The position resolution achievable by semiconductor detectors is compared with the resolution achievable by gas filled position sensing detectors. Semiconductor detectors are divided into two groups; (i) classical semiconductor diode detectors and (ii) semiconductor memory detectors. Principles of the signal formation and the signal read-out for both groups of detectors are described. New developments of silicon detectors of both groups are reported. copyright 1995 American Institute of Physics

    Heilbron, J.L.

    1989-01-01

    This paper considers the sociological and historical implications of early particle physics. The author explains the nature of historical research and its application to scientific developments and the limitations of personal recollections as research tools. Taking the Bevatron as an example, the paper asks a number of questions about the reasons it was built and why and who benefitted from its use. The article finishes by questioning the relevance of prizes to scientific research and considers the language that particle physicists have adopted in their work from the Greek derivations to the quark types, asking whether physicists' view of themselves has changed and been reflected in their use of language.

  13. Particle identification methods in High Energy Physics

    Energy Technology Data Exchange (ETDEWEB)

    Va' Vra, J.

    2000-01-27

    This paper deals with two major particle identification methods: dE/dx and Cherenkov detection. In the first method, the authors systematically compare existing dE/dx data with various predictions available in the literature, such as the Particle Data group recommendation, and judge the overall consistency. To my knowledge, such comparison was not done yet in a published form for the gaseous detectors used in High-Energy physics. As far as the second method, there are two major Cherenkov light detection techniques: the threshold and the Ring imaging methods. The authors discuss the recent trend in these techniques.

    Quantum theory and relativity theory are fundamental of relativistic quantum mechanics, quantum field theory, which is the base of elementary particle physics, gauge field theory and basic force unification models. After a short introduction of relativistic equations of the main fields, the free scalar field, the free vector field, the free electromagnetic field and the free spinor field, and of elementary particles and basic interactions, gauge invariance and electromagnetic gauge field are detailed. Then the presentation of internal degrees of freedom, especially isospin, introduces gauge field theory of Yang-Mills. At last weak interactions and strong interactions are presented and lead to grand unification theory in conclusion [fr

    The Kaon Factory at TRIUMF will produce beams of kaons, antiprotons, neutrinos and other particles with a hundred-fold increase in intensity over existing machines in the 30 GeV region. This will make possible new high precision experiments designed to test current ideas as well as high sensitivity measurements which could potentially reveal new effects. A sample of particle physics experiments involving rare kaon decays, CP and T violation studies, neutrino properties and reactions and light quark spectroscopy which might take advantage of the new opportunities presented by the Kaon Factory is discussed

    Antia, A N; Peinert, R

    1999-01-01

    Results are presented from particle flux studies using sediment trap and current meter moorings along a transect at the European continental margin at 49 degrees N within the Ocean Margin Exchange (OMEX) project. Two moorings were placed, at the mid- and outer slope in water depths of 1500 and 3660 m, with traps at 600 and 1050 m and at 580, 1440 and 3220 m, respectively. Residual currents at the mid- slope follow the slope contour, whereas seasonal off-slope flow was registered at the outer slope. At 600 m on the slope fluxes are similar to those in the abyssal North Atlantic. The flux of all components (bulk dry weight, particulate organic and inorganic carbon, lithogenic matter and opal) increased with water depth. Highest fluxes were recorded at 1440 m at the outer slope, where off- slope residual currents mediate particle export. The injection of biogenic and lithogenic particles below the depth of winter mixing results in the export of particles from shallower waters. Calculated lateral fluxes of partic...

  19. Introduction to particle and astroparticle physics multimessenger astronomy and its particle physics foundations

    CERN Document Server

    De Angelis, Alessandro

    2018-01-01

    This book introduces particle physics, astrophysics and cosmology. Starting from an experimental perspective, it provides a unified view of these fields that reflects the very rapid advances being made. This new edition has a number of improvements and has been updated to describe the recent discovery of gravitational waves and astrophysical neutrinos, which started the new era of multimessenger astrophysics; it also includes new results on the Higgs particle. Astroparticle and particle physics share a common problem: we still don’t have a description of the main ingredients of the Universe from the point of view of its energy budget. Addressing these fascinating issues, and offering a balanced introduction to particle and astroparticle physics that requires only a basic understanding of quantum and classical physics, this book is a valuable resource, particularly for advanced undergraduate students and for those embarking on graduate courses. It includes exercises that offer readers practical insights. It ...

  3. Applications of Particle Accelerators in Medical Physics

    CERN Document Server

    Cuttone, G

    2008-01-01

    Particle accelerators are often associated to high energy or nuclear physics. As well pointed out in literature [1] if we kindly analyse the number of installation worldwide we can easily note that about 50% is mainly devoted to medical applications (radiotherapy, medical radioisotopes production, biomedical research). Particle accelerators are also playing an important indirect role considering the improvement of the technical features of medical diagnostic. In fact the use of radionuclide for advanced medical imaging is strongly increasing either in conventional radiography (CT and MRI) and also in nuclear medicine for Spect an PET imaging. In this paper role of particle accelerators for medical applications will be presented together with the main solutions applied.

  4. Calorimetry energy measurement in particle physics

    CERN Document Server

    Wigmans, Richard

    2017-01-01

    Particle physics is the science that pursues the age-old quest for the innermost structure of matter and the fundamental interactions between its constituents. Modern experiments in this field rely increasingly on calorimetry, a detection technique in which the particles of interest are absorbed in the detector. Calorimeters are very intricate instruments. Their performance characteristics depend on subtle, sometimes counter-intuitive design details. This book, written by one of the world's foremost experts, is the first comprehensive text on this topic. It provides a fundamental and systematic introduction to calorimetry. It describes the state of the art in terms of both the fundamental understanding of calorimetric particle detection, and the actual detectors that have been or are being built and operated in experiments. The last chapter discusses landmark scientific discoveries in which calorimetry has played an important role. This book summarizes and puts into perspective the work described in some 900...

  5. The ideas of particle physics. 2. ed.

    International Nuclear Information System (INIS)

    Coughlan, G.D.; Dodd, J.E.

    1991-01-01

    Our main concern in writing this book has been to communicate the central ideas and concepts of elementary particle physics. We have attempted to present a comprehensive overview of the subject at a level which carries the reader beyond the simplifications and generalisations necessary in popular science books. Matter consists of just two types of elementary particles: quarks and leptons. These are the fundamental building blocks of the material world. The theory describing the microscopic behaviour of these particles has, over the past decade or so, become known as the 'standard model', providing as it does an accurate account of the force of electromagnetism, the weak nuclear force (responsible for radioactive decay), and the strong nuclear force (which holds atomic nuclei together). The standard model has been remarkably successful; all experimental tests have verified the detailed predictions of the theory. (author)

    We describe the multi-purpose Monte-Carlo event generator WHIZARD for the simulation of high-energy particle physics experiments. Besides the presentation of the general features of the program like SM physics, BSM physics, and QCD effects, special emphasis is given to the support of the most accurate simulation of the collider environments at hadron colliders and especially at future linear lepton colliders. On the more technical side, the very recent code refactoring towards a completely object-oriented software package to improve maintainability, flexibility and code development are discussed. Finally, we present ongoing work and future plans regarding higher-order corrections, more general model support including the setup to search for new physics in vector boson scattering at the LHC, as well as several lines of performance improvements.

    2018-01-01

    The most important discovery in particle physics in recent years was that of the Higgs boson, and much effort is continuing to measure its properties, which agree obstinately with the Standard Model, so far. However, there are many reasons to expect physics beyond the Standard Model, motivated by the stability of the electroweak vacuum, the existence of dark matter and the origin of the visible matter in the Universe, neutrino physics, the hierarchy of mass scales in physics, cosmological inflation and the need for a quantum theory for gravity. Most of these issues are being addressed by the experiments during Run 2 of the LHC, and supersymmetry could help resolve many of them. In addition to the prospects for the LHC, I also review briefly those for direct searches for dark matter and possible future colliders.

  10. Advanced analysis methods in particle physics

    Energy Technology Data Exchange (ETDEWEB)

    Bhat, Pushpalatha C.; /Fermilab

    2010-10-01

    Each generation of high energy physics experiments is grander in scale than the previous - more powerful, more complex and more demanding in terms of data handling and analysis. The spectacular performance of the Tevatron and the beginning of operations of the Large Hadron Collider, have placed us at the threshold of a new era in particle physics. The discovery of the Higgs boson or another agent of electroweak symmetry breaking and evidence of new physics may be just around the corner. The greatest challenge in these pursuits is to extract the extremely rare signals, if any, from huge backgrounds arising from known physics processes. The use of advanced analysis techniques is crucial in achieving this goal. In this review, I discuss the concepts of optimal analysis, some important advanced analysis methods and a few examples. The judicious use of these advanced methods should enable new discoveries and produce results with better precision, robustness and clarity.

    AUTHOR|(INSPIRE)INSPIRE-00452332

    The present dissertation describes design, qualification and operation of several electronic instrumentations for High Energy Particle Physics experiments (LHCb) and Neutrino Physics experiments (CUORE and CUPID). Starting from 2019, the LHCb experiment at the LHC accelerator will be upgraded to operate at higher luminosity and several of its detectors will be redesigned. The RICH detector will require a completely new optoelectronic readout system. The development of such system has already reached an advanced phase, and several tests at particle beam facilities allowed to qualify the performance of the entire system. In order to achieve a higher stability and a better power supply regulation for the front-end chip, a rad-hard low dropout linear regulator, named ALDO, has been developed. Design strategies, performance tests and results from the irradiation campaign are presented. In the Neutrino Physics field, large-scale bolometric detectors, like those adopted by CUORE and its future upgrade CUPID, offer u...

    Geant4 is a showcase example of technology transfer from particle physics to other fields such as space and medical science. Geant4 was first used for space applications by ESA in 1999, when ESA and NASA each launched an X-ray telescope. Geant4's extended set of physics models, which handle both electromagnetic and hadronic interactions, can be used to address a range of medical applications from conventional photon-beam radiotherapy to brachytherapy (using radioactive sources), hadron therapy and boron neutron capture therapy. The tools for describing geometries, materials and electromagnetic fields can precisely model diverse real-life configurations.

    "It was the best of times; it was the worst of times" is the way Dickens begins the Tale of Two Cities. The line is appropriate to our time in particle physics. It is the best of times because we are in the midst of a revolution in understanding, the third to occur during my career. It is the worst of times because accelerator facilities are shutting down before new ones are opening, restricting the opportunity for experiments, and because of great uncertainty about future funding. My task today is to give you a view of the most important opportunities for our field under a scenario that is constrained by a tight budget. It is a time when we cannot afford the merely good, but must give first priority to the really important. The defining theme of particle physics is to learn what the universe is made of and how it all works. This definition spans the full range of size from the largest things to the smallest things. This particle physics revolution has its origins in experiments that look at both.

    The paper presents the design process we followed to recast particle physics so as to make it conceptually relevant for secondary school students. In this design process, the concept of symmetry was assumed as core-idea because of its structural and foundational role in particle physics, its crosscutting character and its epistemological and philosophical value. The first draft of the materials was tested in a pilot-study which involved 19 students of a regular class (grade 13) of an Italian school. The data analysis showed that the students were in their 'regime of competence' for grasping subtle nuances of the materials and for providing important hints for revising them. In particular, students’ reactions brought into light the need of clarifying the 'foundational' character that symmetry attained in twentieth-century physics. The delicate step of re-thinking the materials required the researchers to articulate the complex relationship between researches on physics teaching, history and philosophy of physics. This analytic phase resulted in a version of the materials which implies the students to be guided to grasp the meaning of symmetry as normative principle in twentieth-century physics, throughout the exploration of the different meanings assumed by symmetry over time. The whole process led also to the production of an essential, on-line version, of the materials targeted to a wider audience.

  14. Impact of detector simulation in particle physics collider experiments

    Science.gov (United States)

    Daniel Elvira, V.

    2017-06-01

    Through the last three decades, accurate simulation of the interactions of particles with matter and modeling of detector geometries has proven to be of critical importance to the success of the international high-energy physics (HEP) experimental programs. For example, the detailed detector modeling and accurate physics of the Geant4-based simulation software of the CMS and ATLAS particle physics experiments at the European Center of Nuclear Research (CERN) Large Hadron Collider (LHC) was a determinant factor for these collaborations to deliver physics results of outstanding quality faster than any hadron collider experiment ever before. This review article highlights the impact of detector simulation on particle physics collider experiments. It presents numerous examples of the use of simulation, from detector design and optimization, through software and computing development and testing, to cases where the use of simulation samples made a difference in the precision of the physics results and publication turnaround, from data-taking to submission. It also presents estimates of the cost and economic impact of simulation in the CMS experiment. Future experiments will collect orders of magnitude more data with increasingly complex detectors, taxing heavily the performance of simulation and reconstruction software. Consequently, exploring solutions to speed up simulation and reconstruction software to satisfy the growing demand of computing resources in a time of flat budgets is a matter that deserves immediate attention. The article ends with a short discussion on the potential solutions that are being considered, based on leveraging core count growth in multicore machines, using new generation coprocessors, and re-engineering HEP code for concurrency and parallel computing.

    The research in the field of elementary particle physics concerns hadronic processes at high energies, using the facilities offered by CERN and Fermilab, USA. The teams carrying out experiments with bubble chambers are mainly working at the institute, whereas the tems utilizing counter techniques spend long periods at CERN. Experiments at CERN SPS and Fermilab are in progress. The equipment for bubble chamber physics at the institute consists of five scanning tables, one manual measuring machine and the Spiral Reader measuring machine. A computer CD 6400 is available at the institute. The research program comprises study of 100 GeV/c antiproton-deuterium reactions, 12 GeV/c antiproton-deuterium reactions, 9 and 12 GeV/c antiproton-proton reactions studying all annihilation and non-annihilation processes, a detailed study of amplitudes in 4 GeV/c π - p reactions with strange particles, strange particle production in 19 GeV/c pp and study of 19 GeV/c pd. The main emphasis in the future will be on experiments with the European Hybrid Spectrometer system and the Big European Bubble Chamber at SPS. The group participates in the design work and planning for the physics experiments. Research physicists from the group participate in counter experiments at SPS studying elastic scattering at high transverse momenta, elastic scattering of π, K and p sup(+-) at PS energies and study of line reversal invariance in πp and Kp reactions.

    The behavior of matter in physically extreme conditions is in focus of many high-energy-physics experiments. For this purpose, high energy charged particles (ions) are collided with each other and energy- or baryon densities are created similar to those at the beginning of the universe or to those which can be found in the center of neutron stars. In both cases a plasma of quarks and gluons (QGP) is present, which immediately decomposes to hadrons within a short period of time. At this process, particles are formed, which allow statements about the beginning of the universe when captured by large detectors, but which also lead to the massive occurance of hardware failures within the detector's electronic devices. This contribution is about methods to mitigate radiation susceptibility for Field Programmable Gate Arrays (FPGA), enabling them to be used within particle detector systems to directly gain valid data in the readout chain or to be used as detector-control-system.

  18. Electron cooling and elementary particle physics

    International Nuclear Information System (INIS)

    Budker, G.I.; Skrinskij, A.N.

    1978-01-01

    This review is devoted to a new method in experimental physics - the electron cooling. This method opens possibilities in storing the intense and highly monochromatic beams of heavy particles and allows to carry out a wide series of experiments of a high luminocity and resolution. The method is based on the beam cooling by an accompanying flux of electrons. The cooling is due to Coulomb collisions of the beam particles with electrons. In the first part the theoretical aspects of the method are considered shortly. The layout of the NAP-M installation with electron cooling and results of successful experiments on cooling the proton beam are given. In the second part the new possibilities are discussed which appear due to application of electron cooling: storing the intense antiproton beams and realization of the proton - antiproton colliding beams, carrying out experiments with the super fine targets in storage rings, experiments with particles and antiparticles at ultimately low energies, storing the polarized antiprotons and other particles, production of antiatoms, antideuton storing, experiments with ion beams

    2002-01-01

    Progress in particle physics has been tightly related to technological advances during the past half century. Progress in technologies has been driven in many cases by the needs of particle physics. Often, these advances have benefited fields beyond particle physics: other scientific fields, medicine, industrial development, and even found commercial applications. The particle physics and technology working group of Snowmass 2001 reviewed leading-edge technologies recently developed or in the need of development for particle physics. The group has identified key areas where technological advances are vital for progress in the field, areas of opportunities where particle physics may play a principle role in fostering progress, and areas where advances in other fields may directly benefit particle physics. The group has also surveyed the technologies specifically developed or enhanced by research in particle physics that benefit other fields and/or society at large

  2. Accelerators for elementary particle physics in Europe

    Schopper, H.

    1983-01-01

    The European accelerator programme provides for physicists from Europe and other continents facilities to carry out an exciting physics programme both in the medium- and long-term future. During the last decade a concentration of activities took place. The major high energy physics laboratory in Europe is CERN which, with its 13 Member States, is the only international laboratory in the field of high energy physics. About 2.500 physicists carry out their research there and they come not only from the Member States but also from the United States, USSR, Japan, China, Israel etc. Its attraction stems from the fact that most of its facilities are unique. The second laboratory for high energy physics is DESY in Hamburg. Although being a national laboratory it has always been open to physicists from other countries.In particular, since the operation of PETRA started, it has attracted many physicists from Europe and other regions. All high energy experiments at DESY are carried out in international collaborations: there are about 400 physicists involved, some 180 come from foreign universities and research institutes and about 150 from German universities and research laboratories.

  3. When cosmology and particle physics met

    International Nuclear Information System (INIS)

    Kaiser, D.

    2007-01-01

    Primordial cosmology describes the first moments of the universe when the interactions of elementary particles with one another determined its evolution. The mutual ignorance between the community of cosmologists with that of elementary physicists is well illustrated by the fact that both communities conceived distinct concepts of mass that 10 years later were found similar: Brans-Dicke gravitation and Higgs field. Now the collaboration between cosmology and particle physics appears necessary since the great unification theory that imposes the 3 basic forces: weak interaction, electromagnetic interaction and strong interaction to merge in a unique force at an energy scale of 10 24 eV, is supposed to have occurred just after the big-bang when the universe was dense and hot. (A.C.)

  4. Open Access Publishing in Particle Physics

    CERN Document Server

    2007-01-01

    Particle Physics, often referred to as High Energy Physics (HEP), spearheaded the Open Access dissemination of scientific results with the mass mailing of preprints in the pre-Web era and with the launch of the arXiv preprint system at the dawn of the '90s. The HEP community is now ready for a further push to Open Access while retaining all the advantages of the peerreview system and, at the same time, bring the spiralling cost of journal subscriptions under control. I will present a plan for the conversion to Open Access of HEP peer-reviewed journals, through a consortium of HEP funding agencies, laboratories and libraries: SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics). SCOAP3 will engage with scientific publishers towards building a sustainable model for Open Access publishing, which is as transparent as possible for HEP authors. The current system in which journals income comes from subscription fees is replaced with a scheme where SCOAP3 compensates publishers for the costs...

  5. Particle physics - Recent successes and future prospects

    International Nuclear Information System (INIS)

    Wojcicki, S.

    1985-01-01

    The situation in particle physics today is highly analogous to that which existed in chemistry towards the end of the 19th century. During the preceding two centuries, remarkable progress has been achieved in that discipline, progress that culminated in the periodic table of Mendeleyev. This paper summarized not only the realization that the everyday matter is composed of basic building blocks, called elements, but also that these different elements had certain similarities which could be used to properly arrange them in the periodic table. Thus the inert gases (helium, neon, argon, etc.) had very similar chemical properties, namely chemical inertness; the halogens (chlorine, iodine, florine) on the other hand were highly reactive. Other similarities were seen among the rare earth group of elements, alkaline earths, and alkali metals. In this paper the author attempts to summarize briefly the historical background that led us to the present level of understanding, or more specifically to the ''standard model'' of particle physics. He also describes several difficulties with this picture, continues with some possible indications of new physics, and finally end with the discussion of the prospects for the future

  6. The Particle Physics Data Grid. Final Report

    2002-01-01

    The main objective of the Particle Physics Data Grid (PPDG) project has been to implement and evaluate distributed (Grid-enabled) data access and management technology for current and future particle and nuclear physics experiments. The specific goals of PPDG have been to design, implement, and deploy a Grid-based software infrastructure capable of supporting the data generation, processing and analysis needs common to the physics experiments represented by the participants, and to adapt experiment-specific software to operate in the Grid environment and to exploit this infrastructure. To accomplish these goals, the PPDG focused on the implementation and deployment of several critical services: reliable and efficient file replication service, high-speed data transfer services, multisite file caching and staging service, and reliable and recoverable job management services. The focus of the activity was the job management services and the interplay between these services and distributed data access in a Grid environment. Software was developed to study the interaction between HENP applications and distributed data storage fabric. One key conclusion was the need for a reliable and recoverable tool for managing large collections of interdependent jobs. An attached document provides an overview of the current status of the Directed Acyclic Graph Manager (DAGMan) with its main features and capabilities

    This very long-running grant has supported many experiments in nuclear and particle physics by a group from the University of New Mexico. The gamut of these experiments runs from many aspects of Strangeness Nuclear Physics, to rare Kaon decays, to searches for exotic Hadrons such as Pentaquark or H-Dibaryon, and finally to Spin Physics within the PHENIX collaboration at RHIC. These experiments were performed at a number of laboratories worldwide: first and foremost at Brookhaven National Lab (BNL), but also at CERN, KEK, and most recently at J-PARC. In this Final Technical Report we summarize progress and achievements for this award since our last Progress Report, i.e. for the period of fall 2013 until the award’s termination on November 30, 2015. The report consists of two parts, representing our two most recent experimental efforts, participation in the Nucleon Spin Physics program of the PHENIX experiment at RHIC, the Relativistic Heavy Ion Collider at BNL – Task 1, led by Douglas Fields; and participation in several Strangeness Nuclear Physics experiments at J-PARC, the Japan Proton Accelerator Research Center in Tokai-mura, Japan – Task 2, led by Bernd Bassalleck.

    Reviews recent discoveries in the field of particle physics and places them in a theoretical framework. Then shows what is to be expected from the CERN SPS, and from the Fermi laboratory in America where a machine analogous to the SPS is already in service. Better secondary beams should improve our knowledge of lepton-hadron scattering processes, thus providing information about hadron structure and also, with v-scattering, on weak interactions. More should also be learned about proton-proton scattering. (0 refs).

  15. Particle physics in intense electromagnetic fields

    International Nuclear Information System (INIS)

    Kurilin, A.V.

    1999-01-01

    The quantum field theory in the presence of classical background electromagnetic field is reviewed giving a pedagogical introduction to the Feynman-Furry method of describing non-perturbative interactions with very strong electromagnetic fields. A particular emphasis is given to the case of the plane-wave electromagnetic field for which the charged particles' wave functions and propagators are presented. Some general features of quantum processes proceeding in the intense electromagnetic background are argued. The possibilities of searching new physics through the investigations of quantum phenomena induced by a strong electromagnetic environment are also discussed

  16. The experimental foundations of particle physics

    International Nuclear Information System (INIS)

    Cahn, R.N.; Goldhaber, G.

    1987-01-01

    This book describes the development of modern particle physics, emphasizing the role and significance of crucial experiments. This description is supported by a selection of reprints of notable experimental papers. Beginning at the turn of the century with the discovery of radioactivity, x-rays, and the Thomson model of the atom, the authors take the reader through the great developments of the twentieth century, culminating in a description of the electroweak theory and the discovery of the W and Z vector bosons. The bulk of this book is written in non-technical language, although more technical passages are included and extensive references to review articles and books are given

  17. The rising sun of particle physics

    International Nuclear Information System (INIS)

    Fraser, G.

    1985-01-01

    A new entrant is set to join the select league of big-time high energy Laboratories. Thanks to imaginative planning and hard work, the Japanese KEK (Ko Enerugi butsurigaku Kenkyusho) National Laboratory will soon become a new world focus for particle physics research. KEK's original research programme was (and still is) based on a modest 12 GeV Proton Synchrotron which began regular operation in 1977. But even before this got underway, plans were being prepared for a big new machine which would push the Laboratory to the forefront of physics. The TRISTAN project as initially proposed forsaw a variety of colliding beam options, hence the name 'TRi-ring Intersecting STorage Accelerators in Nippon'. Subsequent thinking focused on the electron-positron option, leaving other possibilities for the future. Hence the Tri-ring in the original name has been modified to 'TRansposable Ring'.

  19. Tests of the particle physics-physical cosmology interface

    International Nuclear Information System (INIS)

    Schramm, D.N.

    1993-01-01

    Three interrelated interfaces of particle physics and physical cosmology are discussed: (1) inflation and other phase transitions; (2) Big Bang Nucleosynthesis (and also the quark-hadron transition); and (3) structure formation (including dark matter). Recent observations that affect each of these topics are discussed. Topic number 1 is shown to be consistent with the COBE observations but not proven and it may be having problems with some age-expansion data. Topic number 2 has now been well-tested and is an established ''pillar'' of the Big Bang. Topic number 3 is the prime arena of current physical cosmological activity. Experiments to resolve the current exciting, but still ambiguous, situation following the COBE results are discussed

  20. Cosmology, physics of particles and nuclei

    International Nuclear Information System (INIS)

    2003-01-01

    A recent trend, already noted in the previous activity report, is the cross-fertilization between cosmology and high-energy physics, with some twenty research articles at this interface in the last 2 years. Results are presented along 3 main directions. 1) Cosmology and astro-particle physics. One may quote among others: the idea that dark matter may not be as weakly interacting as previously thought; a general study of the growth of small perturbations in the context of higher-dimensional theories; a possible explanation of the smallness of the cosmological constant through violation of Lorentz invariance in the gravity sector. In the field of observational cosmology, a 3-point correlation has been detected for the first time using gravitational lensing experiments. 2) Particle physics beyond the standard model. New developments in this field are triggered by progress on both experimental and theoretical sides. The first unambiguous observation of neutrino oscillations implies that neutrinos have non-zero masses. The constraints imposed by existing data on models based on the seesaw mechanism have been studied. The 'de-construction' of supersymmetric theories, inspired by recent advances in higher-dimensional theories, leads to a parameter-free prediction for the mass of the Higgs boson. 3) Strong interactions. Experiments at Hera have triggered new studies of hadronic interactions in the regime of high parton densities, which is also the high-energy limit for QCD: the phenomenon of 'parton saturation' is expected to occur. QCD calculations have been applied to various observables: jet physics, diffractive processes at Hera and in collider experiments, and multiplicity correlations in phase space. (A.C.)

    2012-01-01

    This year marks the 10th anniversary of the European Network for Light Ion Therapy (ENLIGHT), which is a good occasion a look back over the important contributions particle physics has made to medicine over the years. It’s hard to know exactly where to start, but since this year also marks the 20th anniversary of Georges Charpak’s Nobel Prize, that seems as good a place as any.   Charpak’s prize was a long time coming. It was awarded for “his invention and development of particle detectors, in particular the multiwire proportional chamber” in 1968. Over the following years, these devices transformed particle physics, allowing particle collisions to be recorded electronically instead of optically, and they led to a wide range of electronic particle detection techniques in use today. All this was duly noted by the Nobel committee, which also pointed out Charpak’s energy in applying the technology to medicine. Today, Charpak-like detec...

  7. Hot spots in nuclear and particle physics

    Stelte, N.

    1981-01-01

    The aim of the present thesis was the study of the phenomenon of the pre-equilibrium process in nuclear and particle physics in the framework of the HS picture. From the comparison of the HS model with inclusive experiments of nuclear physics it could be concluded, that HS's can have an important portion of the pre-equilibrium spectrum. In reactions of hadrons and lighter nuclei with heavy target nuclei the dependence of the HS-induced spectrum from the target mass, the detector angle, the kinetic energy, and as far as data were available, from the kind of the emitted particle as function of the drift parameter, the maximal temperature, and the velocity could be indicated. For forward angles a qualitative to quantitative agreement with the studied data could by shown. For backward angles a quantitative agreement resulted which suggests the conclusion that this angular range is determined by the HS effect even about three orders of magnitude of the incident energy.

  8. Interfaces between particle physics and cosmology

    International Nuclear Information System (INIS)

    1984-01-01

    Among the physicists' attempts to understand the fundamental structure of matter have been the attempts to: (i) find the ultimate constituents of matter; and (ii) to attain a unification of the forces responsible for the interactions among them. Recent progress in these attempts has led to energy scales which can not conceivably be attained in laboratory experiments, but which would not only be present, but would play an important role in the earliest stages of the big bang model of the Universe. We are talking here of an energy scale E about 10 15 GeV, the corresponding temperature, T, being about 10 28 K relevant to times t about 10 -35 sec. after the big bang. Also, many of the ideas of contemporary particle physics lead to dramatic consequences when applied to the very early universe. It is such interfaces between particle physics and cosmology which are reviewed in this lecture. I shall discuss three such interfaces: (i) the generation of the baryon number of the Universe; (ii) a limit on the number of kinds of neutrinos and therefore on the number of quarklepton generations (if we believe in quark-lepton symmetry); and (iii) the neutrino mass

    2014-01-01

    This publication - "Cosmology and Particle Physics beyond Standard Models" - is dedicated to the celebration of the tenth anniversary of the Southeastern European Network in Mathematical and Theoretical Physics (SEENET-MTP). As a Theme Collection, rather than a Monograph or Proceedings, this volume presents a number of reports and overviews, a few research papers and a short note. However, some of them are excellent examples of a nowadays increasingly deep interplay between particle physics and cosmology. Contributions span a wide range of topics in cosmology, particle physics, but also gravity, including the interface of these fields. The presented work is of both theoretical and experimental/ observational nature. The contributions represent recent progress in their respective fields: inflation, dark matter, neutrino physics, supersymmetry, collider physics, string theory, quantum gravity, black hole physics and massive gravity.

    The volume begins with a non-mathematical discussion of the motivation behind, and basic ideas of, elementary-particle physics theory and experiment. The progress over the past two decades with the quark model and unification of the electromagnetic and weak interactions is reviewed. Existing theoretical problems in the field, such as the origin of mass and the unification of the fundamental forces, are detailed, along with experimental programs to test the new theories. Accelerators, instrumentation, and detectors are described for both current and future facilities. Interactions with other areas of both theoretical and applied physics are presented. The sociology of the field is examined regarding the education of graduate students, the organization necessary in large-scale experiments, and the decision-making process involved in high-cost experiments. Finally, conclusions and recommendations for maintaining US excellence in theory and experiment are given. Appendices list both current and planned accelerators, and present statistical data on the US elementary-particle physics program. A glossary is included.

  12. Topics in particle physics and cosmology

    International Nuclear Information System (INIS)

    Hsu, S.D.H.

    1991-01-01

    The Standard Model of particle physics, together with the Big Bang model of the early universe, constitute a framework which encompasses our current understanding of fundamental laws and beginning of our universe. Despite recent speculative trends, quantum field theory remains the theoretical tool of choice for investigating new physics either at high energy colliders, or in the early universe. In this dissertation, several field theoretic phenomena relevant to cosmology or particle physics are explored. A common theme in these explorations is the structure of the vacuum state in quantum field theory. First, we discuss first-order phase transitions in the early universe, in which the effective vacuum state of the universe shifts discontinuously as the temperature drops below some critical point. We find that the dynamics of a certain type of first-order phase transition can lead to production of primordial black holes, which could constitute the dark matter of our universe. Alternatively, supercooled first-order phase transitions may be the cause of an extended inflationary epoch in the early universe, which is generally regarded as necessary to solve several cosmological puzzles. We derive limits on such scenarios based on nearly model-independent percolation properties of the transition. We also study some nonperturbative aspects of the field theory vacuum. We show that non-topological solitons of a single fermion and Higgs fields can only exist in strongly coupled theories. In particular, we find that at the lowest fermionic excitations in the Standard Model are single fermions, and not bound states of fermion plugs Higgs. Finally, we investigate the intriguing behavior of instanton-induced cross sections. We discover Higgs-Higgs cross sections which increase exponentially with center of mass energy due to the presence of instanton solutions related to vacuum instability

    Letić, Milorad; Popović, Gorjana

    2013-01-01

    Changes in dental education towards integration of sciences and convergence of curricula have affected instruction in physics. Earlier studies of undergraduate curricula make possible comparisons in physics instruction. For this study, the websites of 245 European dental schools were explored, and information about the curriculum was found on 213 sites. Physics instruction in the form of a separate course was found in 63 percent of these schools, with eighty-two hours and 5.9 European Credit Transfer and Accumulation System (ECTS) credits on average. Physics integrated with other subjects or into modules was found in 19 percent of these schools. Half of these schools had on average sixty-one hours and 6.9 ECTS credits devoted to physics. Eighteen percent of the schools had no noticeable obligatory physics instruction, but in half of them physics was found to be required or accepted on admission, included in other subjects, or appeared as an elective course. In 122 dental schools, the extent of physics instruction was found to be between forty and 120 contact hours. Physics instruction has been reduced by up to 14 percent in the last fourteen years in the group of eleven countries that were members of the European Union (EU) in 1997, but by approximately 30 percent in last five years in the group of ten Accession Countries to the EU.

    Understanding and controlling the physics of space charge effects in linear and circular proton and ion accelerators are essential to their operation, and to future high-intensity facilities. This book presents the status quo of this field from a theoretical perspective, compares analytical approaches with multi-particle computer simulations and – where available – with experiments. It discusses fundamental concepts of phase space motion, matched beams and modes of perturbation, along with mathematical models of analysis – from envelope to Vlasov-Poisson equations. The main emphasis is on providing a systematic description of incoherent and coherent resonance phenomena; parametric instabilities and sum modes; mismatch and halo; error driven resonances; and emittance exchange due to anisotropy, as well as the role of Landau damping. Their distinctive features are elaborated in the context of numerous sample simulations, and their potential impacts on beam quality degradation and beam loss are discussed....

  18. Magnetic monopoles in particle physics and cosmology

    International Nuclear Information System (INIS)

    Preskill, J.

    1986-01-01

    Hardly any topic better illustrates the connection between particle physics and cosmology than the topic of magnetic monopoles. While there is no persuasive evidence that a monopole has ever been detected, the existence of monopoles is implied by deeply cherished beliefs about the structure of matter at extremely short distances. And the fact that monopoles are so rare as to have escaped detection has profound implications concerning the very early history of the universe. This article gives a brief overview of the theory of magnetic monopoles and its relevance to cosmology. In Section II, the author explains the connection between monopoles and the unification of the fundamental interactions. In Section III, he describes how monopoles might have been produced in the very early universe. Theoretical limits on the abundance of monopoles derived from astrophysical considerations are the subject of Section IV. Section V contains conclusions

    The current research position is summarized, and what could be done in the future to clarify issues which were opened up by the research is indicated. Following on the discussion of the viability of catalyzed fusion, there is presented along with the key experimental results, a short account of the physics surrounding the subject. This is followed by a discussion of key research topics addressed. In consequence of the progress made, it appears that the feasibility of a small-scale fusion based on catalyzed reactions rests on either the remote chance that a yet undiscovered ultraheavy negatively charged elementary particle exists in Nature, or on the possible technical realization of a system based on muon-catalyzed fusion (MuCF) in high-density degenerate hydrogen plasma (density 1000 LHD, temperature O(100 eV)). The lattter is considered to have practical promise

    Study of muon catalysis of nuclear fusion and phenomena commonly referred to as cold fusion has been central to our effort. Muon catalyzed fusion research concentrated primarily on the identification of energy efficient production of muons, and the understanding and control of the density dependence of auto-poisoning (sticking) of the catalyst. We have also developed the in-flight fusion description of the tμ-d reaction, and work in progress shows promise in explaining the fusion cycle anomalies and smallness of sticking as a consequence of the dominant role of such reactions. Our cold fusion work involved the exploration of numerous environments for cold fusion reactions in materials used in the heavy water electrolysis, with emphasis on reactions consistent with the conventional knowledge of nuclear physics reactions. We then considered the possibility that a previously unobserved ultra-heavy particle X - is a catalyst of dd fusion, explaining the low intensity neutrons observed by Jones et. al. 29 refs

The author also introduces a basic algorithm, which enables readers to simulate samples from simple distribution, and describes useful cases for researchers in particle physics.The final chapter is devoted to the basic ideas of Information Theory, which are important in the Bayesian me...

  2. Exceptional quantum geometry and particle physics

    Directory of Open Access Journals (Sweden)

    Michel Dubois-Violette

    2016-11-01

    Full Text Available Based on an interpretation of the quark–lepton symmetry in terms of the unimodularity of the color group SU(3 and on the existence of 3 generations, we develop an argumentation suggesting that the “finite quantum space” corresponding to the exceptional real Jordan algebra of dimension 27 (the Euclidean Albert algebra is relevant for the description of internal spaces in the theory of particles. In particular, the triality which corresponds to the 3 off-diagonal octonionic elements of the exceptional algebra is associated to the 3 generations of the Standard Model while the representation of the octonions as a complex 4-dimensional space C⊕C3 is associated to the quark–lepton symmetry (one complex for the lepton and 3 for the corresponding quark. More generally it is suggested that the replacement of the algebra of real functions on spacetime by the algebra of functions on spacetime with values in a finite-dimensional Euclidean Jordan algebra which plays the role of “the algebra of real functions” on the corresponding almost classical quantum spacetime is relevant in particle physics. This leads us to study the theory of Jordan modules and to develop the differential calculus over Jordan algebras (i.e. to introduce the appropriate notion of differential forms. We formulate the corresponding definition of connections on Jordan modules.

    High energy particle physics experiments investigate the nature of matter through the identification of subatomic particles produced in collisions of protons, electrons, or heavy ions which have been accelerated to very high energies. Future experiments will have hundreds of millions of detector channels to observe the interaction region where collisions take place at a 40 MHz rate. This paper gives an overview of the electronics requirements for such experiments and explains how data reduction, timing distribution, and radiation tolerance in commercial CMOS circuits are achieved for these big systems. As a detailed example, the electronics for the innermost layers of the future tracking detector, the pixel vertex detector, is discussed with special attention to system aspects. A small-scale prototype (130 channels) implemented in standard 0.25 mu m CMOS remains fully functional after a 30 Mrad(SiO/sub 2/) irradiation.

    Simulation of transport and interaction of various particles in complex media and wide energy range (from 1 MeV up to 1 TeV) is very complicated problem that requires valid model of a real process in nature and appropriate solving tool - computer code and data library. A brief overview of computer codes based on Monte Carlo techniques for simulation of transport and interaction of hadrons and ions in wide energy range in three dimensional (3D) geometry is shown. Firstly, a short attention is paid to underline the approach to the solution of the problem - process in nature - by selection of the appropriate 3D model and corresponding tools - computer codes and cross sections data libraries. Process of data collection and evaluation from experimental measurements and theoretical approach to establishing reliable libraries of evaluated cross sections data is Ion g, difficult and not straightforward activity. For this reason, world reference data centers and specialized ones are acknowledged, together with the currently available, state of art evaluated nuclear data libraries, as the ENDF/B-VI, JEF, JENDL, CENDL, BROND, etc. Codes for experimental and theoretical data evaluations (e.g., SAMMY and GNASH) together with the codes for data processing (e.g., NJOY, PREPRO and GRUCON) are briefly described. Examples of data evaluation and data processing to generate computer usable data libraries are shown. Among numerous and various computer codes developed in transport physics of particles, the most general ones are described only: MCNPX, FLUKA and SHIELD. A short overview of basic application of these codes, physical models implemented with their limitations, energy ranges of particles and types of interactions, is given. General information about the codes covers also programming language, operation system, calculation speed and the code availability. An example of increasing computation speed of running MCNPX code using a MPI cluster compared to the code sequential option

    The DIRAC project is developing interware to build and operate distributed computing systems. It provides a development framework and a rich set of services for both Workload and Data Management tasks of large scientific communities. A number of High Energy Physics and Astrophysics collaborations have adopted DIRAC as the base for their computing models. DIRAC was initially developed for the LHCb experiment at LHC, CERN. Later, the Belle II, BES III and CTA experiments as well as the linear collider detector collaborations started using DIRAC for their computing systems. Some of the experiments built their DIRAC-based systems from scratch, others migrated from previous solutions, ad-hoc or based on different middlewares. Adaptation of DIRAC for a particular experiment was enabled through the creation of extensions to meet their specific requirements. Each experiment has a heterogeneous set of computing and storage resources at their disposal that were aggregated through DIRAC into a coherent pool. Users from different experiments can interact with the system in different ways depending on their specific tasks, expertise level and previous experience using command line tools, python APIs or Web Portals. In this contribution we will summarize the experience of using DIRAC in particle physics collaborations. The problems of migration to DIRAC from previous systems and their solutions will be presented. An overview of specific DIRAC extensions will be given. We hope that this review will be useful for experiments considering an update, or for those designing their computing models.

    A digest of the authors opening remarks at the 2011 Hadron Collider Physics Symposium. I have chosen my title to reflect the transitions we are living through, in particle physics overall and in hadron collider physics in particular. Data-taking has ended at the Tevatron, with {approx} 12 fb{sup -1} of {bar p}p interactions delivered to CDF and D0 at {radical}s = 1.96 TeV. The Large Hadron Collider has registered a spectacular first full-year run, with ATLAS and CMS seeing > 5 fb{sup -1}, LHCb recording {approx} 1 fb{sup -1}, and ALICE logging nearly 5 pb{sup -1} of pp data at {radical}s = 7 TeV, plus a healthy dose of Pb-Pb collisions. The transition to a new energy regime and new realms of instantaneous luminosity exceeding 3.5 x 10{sup 33} cm{sup -2} s{sup -1} has brought the advantage of enhanced physics reach and the challenge of pile-up reaching {approx} 15 interactions per beam crossing. I am happy to record that what the experiments have (not) found so far has roused some of my theoretical colleagues from years of complacency and stimulated them to think anew about what the TeV scale might hold. We theorists have had plenty of time to explore many proposals for electroweak symmetry breaking and for new physics that might lie beyond established knowledge. With so many different theoretical inventions in circulation, it is in the nature of things that most will be wrong. Keep in mind that we learn from what experiment tells us is not there, even if it is uncommon to throw a party for ruling something out. Some non-observations may be especially telling: the persistent absence of flavor-changing neutral currents, for example, seems to me more and more an important clue that we have not yet deciphered. It is natural that the search for the avatar of electroweak symmetry breaking preoccupies participants and spectators alike. But it is essential to conceive the physics opportunities before us in their full richness. I would advocate a three-fold approach

  17. Physical working conditions as covered in European monitoring questionnaires

    2017-06-01

    Full Text Available Abstract Background The prevalence of workers with demanding physical working conditions in the European work force remains high, and occupational physical exposures are considered important risk factors for musculoskeletal disorders (MSD, a major burden for both workers and society. Exposures to physical workloads are therefore part of the European nationwide surveys to monitor working conditions and health. An interesting question is to what extent the same domains, dimensions and items referring to the physical workloads are covered in the surveys. The purpose of this paper is to determine 1 which domains and dimensions of the physical workloads are monitored in surveys at the national level and the EU level and 2 the degree of European consensus among these surveys regarding coverage of individual domains and dimensions. Method Items on physical workloads used in one European wide/Spanish and five other European nationwide work environment surveys were classified into the domains and dimensions they cover, using a taxonomy agreed upon among all participating partners. Results The taxonomy reveals that there is a modest overlap between the domains covered in the surveys, but when considering dimensions, the results indicate a lower agreement. The phrasing of items and answering categories differs between the surveys. Among the domains, the three domains covered by all surveys are “lifting, holding & carrying of loads/pushing & pulling of loads”, “awkward body postures” and “vibrations”. The three domains covered less well, that is only by three surveys or less, are “physical work effort”, “working sitting”, and “mixed exposure”. Conclusions This is the fırst thorough overview to evaluate the coverage of domains and dimensions of self-reported physical workloads in a selection of European nationwide surveys. We hope the overview will provide input to the revisions and updates of the individual countries’ surveys in

    Seven calculator programs that do simple chores that arise in elementary particle physics are given. LEGENDRE evaluates the Legendre polynomial series Σa/sub n/P/sub n/(x) at a series of values of x. ASSOCIATED LEGENDRE evaluates the first-associated Legendre polynomial series Σb/sub n/P/sub n/ 1 (x) at a series of values of x. CONFIDENCE calculates confidence levels for chi 2 , Gaussian, or Poisson probability distributions. TWO BODY calculates the c.m. energy, the initial- and final-state c.m. momenta, and the extreme values of t and u for a 2-body reaction. ELLIPSE calculates coordinates of points for drawing an ellipse plot showing the kinematics of a 2-body reaction or decay. DALITZ RECTANGULAR calculates coordinates of points on the boundary of a rectangular Dalitz plot. DALITZ TRIANGULAR calculates coordinates of points on the boundary of a triangular Dalitz plot. There are short versions of CONFIDENCE (EVEN N and POISSON) that calculate confidence levels for the even-degree-of-freedom-chi 2 and the Poisson cases, and there is a short version of TWO BODY (CM) that calculates just the c.m. energy and initial-state momentum. The programs are written for the HP-97 calculator

  1. Effective Lagrangians in elementary particle physics

    International Nuclear Information System (INIS)

    Trahern, C.G.

    1982-01-01

    Non-linear effective Lagrangians are constructed to represent the low energy phenomenology of elementary particles. As approximate descriptions of the dynamics of hadrons, these models simulate the expected (but unproven) behavior of more complex theories such as quantum Chromo-dynamics [QCD]. A general formalism for non-linear models was developed in the late 1960's by Coleman, Wess and Zumino. This dissertation utilizes and extends their work by incorporating some of the advances that have been made in the understanding of quantum field theories in the last decade. In particular the significance of spatial boundary conditions for interpreting the ground state behavior of the non-linear models is investigated. In addition the existence of a dual theory for the non-linear model is discussed. For experimental purposes duality refers to the possibility that in different enrgy regimes there may be wholly distinct kinds of excitations in the physical spectrum. Corresponding to these phenomenological distinctions are mutually exclusive mathematical descriptions. A familiar example is the duality of electric and magnetic charge in electro-dynamics. If magnetic charges do exist, they are expected to be extremely massive states that are unobservable up to very high energies. The analysis of such states within electrodynamics shows that one cannot describe both electric and magnetic charges without admitting the presence of singularities in the electric potential. A completely analogous form of duality is found and discussed for the non-linear models

  2. Introduction to particle and astroparticle physics questions to the Universe

    CERN Document Server

    De Angelis, Alessandro

    2015-01-01

    This book, written by researchers who had been professionals in accelerator physics before becoming leaders of groups in astroparticle physics, introduces both fields in a balanced and elementary way, requiring only a basic knowledge of quantum mechanics on the part of the reader. The early history of particle physics cannot be distinguished from the history of cosmic rays. With the advent of accelerators, however, the importance of cosmic rays in particle physics was lost. This situation persisted until the 1990s, when novel techniques allowed breakthrough discoveries, and exploration of new physics scales now requires returning to cosmic rays. The new profile of scientists in fundamental physics ideally involves the merging of knowledge in astroparticle and particle physics, but the duration of modern experiments is such that people cannot simultaneously be practitioners in both. Introduction to Particle and Astroparticle Physics is designed to bridge the gap between the fields. It can be used...

    1979-01-01

    The idea of a Brownian quasi-particle and the associated differentiable flow (with nonselfadjoint forces) are used here in the context of a stochastic description of the approach towards statistical equilibrium. We show that this quasi-particle flow acquires, at equilibrium, the principal properties of a conservative Hamiltonian flow. Thus the model of Brownian quasi-particles permits us to establish a link between the stochastic description and the Gibbs description of statistical equilibrium

  5. Symmetries and groups in particle physics

    International Nuclear Information System (INIS)

    Scherer, Stefan

    2016-01-01

    The aim of this book consists of a didactic introduction to the group-theoretical considerations and methods, which have led to an ever deeper understanding of the interactions of the elementary particles. The first three chapters deal primarily with the foundations of the representation theory of primarily finite groups, whereby many results are also transferable to compact Lie groups. In the third chapter we discuss the concept of Lie groups and their connection with Lie algebras. In the remaining chapter it is mainly about the application of group theory in physics. Chapter 4 deals with the groups SO(3) and SU(2), which occur in connection with the description of the angular momentum in quantum mechanics. We discuss the Wigner-Eckar theorem together with some applications. In chapter 5 we are employed to the composition properties of strongly interacting systems, so called hadrons, and discuss extensively the transformation properties of quarks with relation to the special unitary groups. The Noether theorem is generally treated in connection to the conservation laws belonging to the Galilei group and the Poincare group. We confine us in chapter 6 to internal symmetries, but explain for that extensively the application to quantum field theory. Especially an outlook on the effect of symmetries in form of so called Ward identities is granted. In chapter 7 we turn towards the gauge principle and discuss first the construction of quantum electrodynamics. In the following we generalize the gauge principle to non-Abelian groups (Yang-Mills theories) and formulate the quantum chromodynamics (QCD). Especially we take a view of ''random'' global symmetries of QCD, especially the chiral symmetry. In chapter 8 we illuminate the phenomenon of spontaneous symmetry breaking both for global and for local symmetries. In the final chapter we work out the group-theoretical structure of the Standard Model. Finally by means of the group SU(5) we take a view to

    In a context of stagnation of the level of health-enhancing physical activity in Europe, this study examines the geographical stratification of sports participation and physical activity (PA) at the regional level in 28 European countries. While previous research has focused on the national approach, this study considers the regional level across 208 European regions. Individual survey data from the Eurobarometer 80.2 is combined with a regional-level approach to the 208 regions to quantify sports participation and PA at the regional level. The results show important differences and a geographical stratification of sports participation and PA among the European regions, albeit following different patterns. In particular, a north-south gap is identified in terms of PA rates and an east-west gap is detected in terms of sports participation levels. Applying the cluster technique, a taxonomy of four different European regions is developed considering both types of indicators. Finally, the existence of sports spatial spillovers among regions is verified, obtaining a positive autocorrelation among neighbouring regions for being involved in PA and sporting activities. The results may have significant implications in terms of policy measures to improve health through PA and sports participation at the regional level in Europe.

The main theme of this meeting was the interplay between edge and core processes in fusion devices. Radiative scenarios, confinement modes, particle exhaust efficiencies, impurity transport, operational limits and control issues have been considered in contributions from almost all European EURATOM associations. This was divided into three sessions: (1) Confinement Modes and Exhaust, (2) Confinement Scalings and Transport and (3) Interplay Edge-Core. A fourth session was devoted to Recent Results from JET and a fifth one to the Status of ITER. This report provides a concise summary of the results presented and gives a survey of the critical issues discussed during the workshop. (author)

  10. High-PT Physics with Identified Particles

    Energy Technology Data Exchange (ETDEWEB)

    Fries, R.; Liu, W.

    2009-11-09

    The suppression of high-P{sub T} particles in heavy ion collisions was one of the key discoveries at the Relativistic Heavy Ion Collider. This is usually parameterized by the average rate of momentum-transfer squared to this particle, {cflx q}. Here we argue that measurements of identified particles at high P{sub T} can lead to complementary information about the medium. The leading particle of a jet can change its identity through interactions with the medium. Tracing such flavor conversions could allow us to constrain the mean free path. Here we review the basic concepts of flavor conversions and discuss applications to particle ratios and elliptic flow. We make a prediction that strangeness is enhanced at high P{sub T} at RHIC energies while its elliptic flow is suppressed.

The anomaly is subtle, and physicists caution that it might still be a statistical fluke. If confirmed, however, it could mark the long-sought discovery of a whole zoo of new particles--and the end of a long-standing model of particle physics.

  13. Two decades of Mexican particle physics at Fermilab

    This report is a view from Fermilab of Mexican particle physics at the Laboratory since about 1980; it is not intended to be a history of Mexican particle physics: that topic is outside the expertise of the writer. The period 1980 to the present coincides with the growth of Mexican experimental particle physics from essentially no activity to its current state where Mexican groups take part in experiments at several of the world's major laboratories. Soon after becoming Fermilab director in 1979, Leon Lederman initiated a program to encourage experimental physics, especially experimental particle physics, in Latin America. At the time, Mexico had significant theoretical particle physics activity, but none in experiment. Following a visit by Lederman to UNAM in 1981, a conference ''Panamerican Symposium on Particle Physics and Technology'' was held in January 1982 at Cocoyoc, Mexico, with about 50 attendees from Europe, North America, and Latin America; these included Lederman, M. Moshinsky, J. Flores, S. Glashow, J. Bjorken, and G. Charpak. Among the conference outcomes were four subsequent similar symposia over the next decade, and a formal Fermilab program to aid Latin American physics (particularly particle physics); it also influenced a decision by Mexican physicist Clicerio Avilez to switch from theoretical to experimental particle physics. The first physics collaboration between Fermilab and Mexico was in particle theory. Post-docs Rodrigo Huerta and Jose Luis Lucio spent 1-2 years at Fermilab starting in 1981, and other theorists (including Augusto Garcia, Arnulfo Zepeda, Matias Moreno and Miguel Angel Perez) also spent time at the Laboratory in the 1980s

CERN physicists are invited to participate in next year’s Masterclass programme, to be held from 11 February to 23 March 2016.   The International Masterclasses in Particle Physics conclude with a video conference, where students from different countries connect with moderators at CERN to discuss their results.   During a Masterclass, high-school students work with recent data from the LHC experiments under the supervision of physicists. For example, students can rediscover the Z boson or the structure of the proton, reconstruct strange particles or measure the lifetime of the D0 particle. “Students get a taste of how modern physics research works by working directly with particle physicists and using real LHC data,” says Uta Bilow from TU Dresden, coordinator of the International Mas...

    Nuclear science and particle physics is an important subject in physics, and it is important to launch particle physics experiments in university to training students. We design an experiments platform based on particle physics experiments in university. By employing digitalization and reconfiguration techniques in our design, we achieve all kinds of device functions with only one device. With the customized software for particular experiments and a website for teaching assistance, the platform is easy to be employed in universities. Students can accomplish a classical particle physics experiment in a modern way with the help of the platform, and they can also try new ideals. The experiments platform is ready to be used, and some of the lab sessions in USTC have already begin to use our experiments platform. (authors)

  20. Symmetry and conservation laws in particle physics in the fifties

    International Nuclear Information System (INIS)

    Michel, L.

    1989-01-01

    This paper puzzles over why symmetry, so central to particle physics today, was so little attended to in the 1950s when the need for it was becoming profound, with the notion of parity violation and other break-downs in conservation laws, such as angular momentum and charge conjugation. Group theory, including Lie groups, would also have helped understanding of the particle physics discoveries of the 1950s such as strange particles, resonances, and associated production. They were adopted ten years too late by the physics community. (UK)

  1. A good week for global collaboration in particle physics

    CERN Multimedia

    2015-01-01

    This has been a good week for global collaboration in particle physics. On Wednesday, the CERN family grew by one Associate Member when we received official confirmation that the accession agreement signed last year had been ratified by the Turkish parliament, and on Thursday, we signed a new cooperation agreement with the US.   The signature of a new cooperation agreement between CERN and the US at the White House on Thursday, 7 May marks both a renewal of a long-standing friendship and a commitment to take the partnership further. Signed between CERN, the US Department of Energy and the US National Science Foundation, it is a framework agreement that paves the way for detailed accords on continued US participation in CERN’s scientific programme, and on European collaboration in projects hosted in the US, including prospective neutrino facilities. It is an agreement that is tacitly renewed every five years, unless one of the signatories signals a need to end or amend it. I am part...

    Existing results and some conjectures in the flat-space twistor approach to fundamental particles are reviewed. A consice introduction into the twistor description of dynamical systems with rest-mass is given (both classical and quantum). The Hamiltonian structure inherent to the angular momentum twistor is analyzed. The following discussion outlines the properties of n-twistor systems, the Penrose classification of particles, the Isup(10)SU(3) group and the problem of its twistor representations. Finally, speculative arguments are propounded as to the possible bearings of hadronic quark model to twistor theory. (Sz.N.Z.)

  5. Challenging particle physics as path to truth

    2001-01-01

    Particle physicist's ultimate goal is 'grand unification' - describing the four forces observed today - electromagnetism, weak and strong nuclear forces and gravity with just a single law, expressable as a few concise equations. But some solid state physicists are now contesting the validity of this approach, arguing that many forms of matter cannot be described solely in terms of fundamental particle interactions - when systems are very complex, new and independent laws emerge. They propose that there is no one theory of everything, just a lot of theories of things.

  12. Energetic particle physics with applications in fusion and space plasmas

    International Nuclear Information System (INIS)

    Cheng, C.Z.

    1997-01-01

    Energetic particle physics is the study of the effects of energetic particles on collective electromagnetic (EM) instabilities and energetic particle transport in plasmas. Anomalously large energetic particle transport is often caused by low frequency MHD instabilities, which are driven by these energetic particles in the presence of a much denser background of thermal particles. The theory of collective energetic particle phenomena studies complex wave-particle interactions in which particle kinetic physics involving small spatial and fast temporal scales can strongly affect the MHD structure and long-time behavior of plasmas. The difficulty of modeling kinetic-MHD multiscale coupling processes stems from the disparate scales which are traditionally analyzed separately: the macroscale MHD phenomena are studied using the fluid MHD framework, while microscale kinetic phenomena are best described by complicated kinetic theories. The authors have developed a kinetic-MHD model that properly incorporates major particle kinetic effects into the MHD fluid description. For tokamak plasmas a nonvariational kinetic-MHD stability code, the NOVA-K code, has been successfully developed and applied to study problems such as the excitation of fishbone and Toroidal Alfven Eigenmodes (TAE) and the sawtooth stabilization by energetic ions in tokamaks. In space plasmas the authors have employed the kinetic-MHD model to study the energetic particle effects on the ballooning-mirror instability which explains the multisatellite observation of the stability and field-aligned structure of compressional Pc 5 waves in the magnetospheric ring current plasma

    2011-01-01

    While elementary particle physics is an extraordinarily fascinating field, the huge amount of knowledge necessary to perform cutting-edge research poses a formidable challenge for students. The leap from the material contained in the standard graduate course sequence to the frontiers of M-theory, for example, is tremendous. To make substantial contributions to the field, students must first confront a long reading list of texts on quantum field theory, general relativity, gauge theory, particle interactions, conformal field theory, and string theory. Moreover, waves of new mathematics are required at each stage, spanning a broad set of topics including algebra, geometry, topology, and analysis. Symmetry and the Standard Model: Mathematics and Particle Physics, by Matthew Robinson, is the first volume of a series intended to teach math in a way that is catered to physicists. Following a brief review of classical physics at the undergraduate level and a preview of particle physics from an experimentalist's per...

    We discuss aspects of antihydrogen studies, that relate to particle physics ideas and techniques, within the context of the ALPHA experiment at CERN's Antiproton Decelerator facility. We review the fundamental physics motivations for antihydrogen studies, and their potential physics reach. We argue that initial spectroscopy measurements, once antihydrogen is trapped, could provide competitive tests of CPT, possibly probing physics at the Planck Scale. We discuss some of the particle detection techniques used in ALPHA. Preliminary results from commissioning studies of a partial system of the ALPHA Si vertex detector are presented, the results of which highlight the power of annihilation vertex detection capability in antihydrogen studies.

    The author describes the work of particle physicists in the 1950's and focuses on three broad characteristics of the era. Firstly rapid developments occurred. Experiments had timescales of a few months, rarely more than a year. Secondly, many new ideas were formulated, a good proportion of which were useful, and lastly, experimental discoveries were the driving force behind progress. Experimental advances, including accelerator and detector design, relied heavily on the substantial funding which was made available then. (UK)

  10. Particle modeling of plasmas computational plasma physics

    International Nuclear Information System (INIS)

    Dawson, J.M.

    1991-01-01

    Recently, through the development of supercomputers, a powerful new method for exploring plasmas has emerged; it is computer modeling of plasmas. Such modeling can duplicate many of the complex processes that go on in a plasma and allow scientists to understand what the important processes are. It helps scientists gain an intuition about this complex state of matter. It allows scientists and engineers to explore new ideas on how to use plasma before building costly experiments; it allows them to determine if they are on the right track. It can duplicate the operation of devices and thus reduce the need to build complex and expensive devices for research and development. This is an exciting new endeavor that is in its infancy, but which can play an important role in the scientific and technological competitiveness of the US. There are a wide range of plasma models that are in use. There are particle models, fluid models, hybrid particle fluid models. These can come in many forms, such as explicit models, implicit models, reduced dimensional models, electrostatic models, magnetostatic models, electromagnetic models, and almost an endless variety of other models. Here the author will only discuss particle models. He will give a few examples of the use of such models; these will be taken from work done by the Plasma Modeling Group at UCLA because he is most familiar with work. However, it only gives a small view of the wide range of work being done around the US, or for that matter around the world

    1991-01-01

    This Resource Letter provides a guide to literature on the history of modern elementary-particle physics. Histories that treat developments from the 1930s through the 1980s are focused on and a sampling is included of the historiography covering the period c. 1890--1930, the prehistory of elementary-particle physics as a discipline. Also included are collections of scientific papers, which might be especially valuable to individuals who wish to undertake historical research on particular scientists or subfields of elementary-particle physics. The introduction presents some statistical data and associated references for elementary-particle physics and surveys historiographical approaches and issues that are represented in historical accounts in the bibliography. All references are assigned a rating of E (Elementary), I (Intermediate), or A (Advanced) based on their technical or conceptual difficulty or their appropriateness for a person attempting a graduated study of the history of modern particle physics. That is, items labeled E are suitable for the layman or would be fundamental to a beginning exploration of the history of particle physics, whereas items labeled A are technically demanding (mathematically, historiographically, or philosophically) or would be most appropriate for specialized or advanced examinations of various topics

    Alpha particle physics experiments were done on TFTR during its DT run from 1993 to 1997. These experiments utilized several new alpha particle diagnostics and hundreds of DT discharges to characterize the alpha particle confinement and wave-particle interactions. In general, the results from the alpha particle diagnostics agreed with the classical single particle confinement model in MHD quiescent discharges. The alpha loss due to toroidal field ripple was identified in some cases, and the low radial diffusivity inferred for high energy alphas was consistent with orbit averaging over small scale turbulence. Finally, the observed alpha particle interactions with sawteeth, toroidal Alfven eigenmodes and ICRF waves were approximately consistent with theoretical modelling. What was learned is reviewed and what remains to be understood is identified. (author)

  13. Physical characterization of diesel exhaust nucleation mode particles

    Energy Technology Data Exchange (ETDEWEB)

    Lahde, T.

    2013-11-01

    An increasing concern of the adverse health effects of aerosol particles is forcing the combustion engine industry to develop engines with lower particle emissions. The industry has put most of their efforts into soot control and has achieved a significant reduction in diesel exhaust particle mass. Nevertheless, it is not clear that the large particles, dominating the mass, cause the harmfulness of the exhaust particles in the biological interaction. Nowadays, the harmful potential of diesel exhaust particles often connects with the particle surface area, and the view has turned to particle number below 100 nm size range. Unfortunately, the achieved low exhaust particle mass does not necessarily imply a low particle number. This text focuses on the physical characteristics of diesel exhaust nucleation model particles. The volatility characteristics and the electrical charge state of the particles are studied first. Second, the relation between the nonvolatile nucleation mode emissions and the soot, the nitrogen oxide (NO{sub x}) emissions and the engine parameters are covered. The nucleation mode particles had distinctively different physical characteristics with different after-treatment systems. The nucleation mode was volatile and electrically neutral with a diesel particle filter after-treatment system. Without an after-treatment system or with an after-treatment system with low particle removal efficiency, the nucleation mode was partly nonvolatile and included an electrical charge. The difference suggests different formation routes for the nucleation particles with different after-treatment systems. The existence of the nonvolatile nucleation mode particles also affected the soot mode charge state. The soot charge state was positively biased when the nonvolatile nucleation mode was detected but slightly negatively biased when the nonvolatile nucleation mode was absent. The nonvolatile nucleation mode was always negatively biased. This electrical charge

    Energy Technology Data Exchange (ETDEWEB)

    Gorelenkov, Nikolai N [PPPL

    2013-06-01

    The area of energetic particle (EP) physics of fusion research has been actively and extensively researched in recent decades. The progress achieved in advancing and understanding EP physics has been substantial since the last comprehensive review on this topic by W.W. Heidbrink and G.J. Sadler [1]. That review coincided with the start of deuterium-tritium (DT) experiments on Tokamak Fusion Test reactor (TFTR) and full scale fusion alphas physics studies. Fusion research in recent years has been influenced by EP physics in many ways including the limitations imposed by the "sea" of Alfven eigenmodes (AE) in particular by the toroidicityinduced AEs (TAE) modes and reversed shear Alfven (RSAE). In present paper we attempt a broad review of EP physics progress in tokamaks and spherical tori since the first DT experiments on TFTR and JET (Joint European Torus) including helical/stellarator devices. Introductory discussions on basic ingredients of EP physics, i.e. particle orbits in STs, fundamental diagnostic techniques of EPs and instabilities, wave particle resonances and others are given to help understanding the advanced topics of EP physics. At the end we cover important and interesting physics issues toward the burning plasma experiments such as ITER (International Thermonuclear Experimental Reactor).

  17. Pixel Detectors for Particle Physics and Imaging Applications

    CERN Document Server

    Wermes, N

    2003-01-01

    Semiconductor pixel detectors offer features for the detection of radiation which are interesting for particle physics detectors as well as for imaging e.g. in biomedical applications (radiography, autoradiography, protein crystallography) or in Xray astronomy. At the present time hybrid pixel detectors are technologically mastered to a large extent and large scale particle detectors are being built. Although the physical requirements are often quite different, imaging applications are emerging and interesting prototype results are available. Monolithic detectors, however, offer interesting features for both fields in future applications. The state of development of hybrid and monolithic pixel detectors, excluding CCDs, and their different suitability for particle detection and imaging, is reviewed.

  18. Fundamental concepts in Particle Physics course

    CERN Multimedia

    CERN. Geneva HR-RFA

    2006-01-01

    The course will provide an introduction to some of the basic theoretical techniques used to describe the fundamental particles and their interactions. Of central importance to our understanding of these forces are the underlying symmetries of nature and I will review the nature of these symmetries and how they are used to build a predictive theory. I discuss how the combination of quantum mechanics and relativity leads to the quantum field theory (QFT) description of the states of matter and their interactions. The Feynman rules used to determine the QFT predictions for experimentally measurable processes are derived and applied to the calculation of decay widths and cross sections.

  19. New developments in elementary-particle physics

    CERN Document Server

    Zichichi, A

    1979-01-01

    The modern attempt at unification of all the forces in nature is based on supersymmetry. To achieve the unification of strong and electroweak forces the distinction between leptons and hadrons (quarks) must go. The fundamental symmetry of nature is the SU(3)/sub c/ gauge symmetry, where c stands for colour. There are three colours which are the basic changes of nature and act between quarks and gluons. Elementary particles are now thought to be made of quarks and gluons. The fundamental forces of nature now appear to be the superstrong (which generates strong and semi-strong forces), electroweak (generating electromagnetic, weak and superweak) and gravitational forces.

  3. Cosmology and particle physics: A general review

    International Nuclear Information System (INIS)

    Olive, K.A.

    1986-01-01

    Cosmology today does not stop at t = 1 s. Indeed, ''reasonable'' statements begin at the Planck epoch or when t ≅ 10/sup -44/s. In this review, the author attempts to highlight the current understanding of the various stages in the evolution of the universe from -- 10/sup -4/s to the period of galaxy formation at t≅10/sup 5/ years. He tries to follow a chronological order for the discussion and begins with the Planck epoch. In the section entitled INFLATION, discusses the inflationary epoch. In the section, GUTs and COSMOLOGY, he reviews the present status of big bang baryosynthesis, i.e., the origin of the apparent slight excess of baryons over antibaryons. This is perhaps the third most reliable piece of evidence indicating a hot big bang. He also reviews the present status of big bang nucleosynthesis and discuss why he feels it is one of the greatest successes of the standard big bang model. Finally, in the last section, he reviews the present role of particles in the universe; that is, their effects on galaxy formation and constraints from present observations that can be placed on particle properties

    1985-01-01

    The possible role of space like objects in elementary particle physics (and in quantum mechanics) is reviewed and discussed, mainly by exploiting the explicit consequences of the peculiar relativistic mechanics of tachyons. Particular attention is paid : 1) to tachyons as the possible carriers of interactions (''internal lines''); e.g., to the links between ''virtual particles'' and superluminal objects; 2) to the possibility of ''vacuum decays'' at the classical level; 3) to a Lorentz-invariant bootstrap model; 4) to the apparent shape of the tachyonic elementary particles (''elementary tachyons'') and its possible connection with the de Broglie wave-particle dualism

    Mitselmakher, G.

    1996-01-01

    In 1995 the University of Florida started a major expansion of the High Energy Experimental Physics group (HEE) with the goal of adding four new faculty level positions to the group in two years. This proposal covers the second year of operation of the new group and gives a projection of the planned research program for the next five years, when the group expects their activities to be broader and well defined. The expansion of the HEE group started in the Fall of 1995 when Guenakh Mitselmakher was hired from Fermilab as a Full Professor. A search was then performed for two junior faculty positions. The first being a Research Scientist/Scholar position which is supported for 9 months by the University on a faculty line at the same level as Assistant Professor but without the teaching duties. The second position is that of an Assistant Professor. The search has been successfully completed and Jacobo Konigsberg from Harvard University has accepted the position of Research Scientist and Andrey Korytov from MIT has accepted the position of Assistant Professor. They will join the group in August 1996. The physics program for the new group is focused on hadron collider physics. G. Mitselmakher has been leading the CMS endcap muon project since 1994. A Korytov is the coordinator of the endcap muon chamber effort for CMS and a member of the CDF collaboration and J. Konigsberg is a member of CDF where he has participated in various physics analyses and has been coordinator of the gas calorimetry group. The group at the U. of Florida has recently been accepted as an official collaborating institution on CDF. They have been assigned the responsibility of determining the collider beam luminosity at CDF and they will also be an active participant in the design and operation of the muon detectors for the intermediate rapidity region. In addition they expect to continue their strong participation in the present and future physics analysis of the CDF data

  7. The low-energy frontier of particle physics

    International Nuclear Information System (INIS)

    Jaeckel, Joerg

    2010-02-01

    Most embeddings of the Standard Model into a more unified theory, in particular the ones based on supergravity or superstrings, predict the existence of a hidden sector of particles which have only very weak interactions with the visible sector Standard Model particles. Some of these exotic particle candidates (such as e.g. ''axions'', ''axion-like particles'' and ''hidden U(1) gauge bosons'') may be very light, with masses in the sub-eV range, and have very weak interactions with photons. Correspondingly, these very weakly interacting sub-eV particles (WISPs) may lead to observable effects in experiments (as well as in astrophysical and cosmological observations) searching for light shining through a wall, for changes in laser polarisation, for non-linear processes in large electromagnetic fields and for deviations from Coulomb's law. We present the physics case and a status report of this emerging low-energy frontier of fundamental physics. (orig.)

    1978-01-01

    Some new developments in elementary particle physics and interaction processes are reviewed. Recent advances in the field of particle physics including the observation of an anomalous behaviour of interaction cross section at high energy levels, the deep inelastic scattering of electrons from protons, the existence of neutral currents and the relative frequency of events with high transverse pulses are pointed out. A special development is the discovery and identification of a number of new particles and processes. New advances in understanding of the structure of subelementary particles, and the combination of electromagnetic and weak interactions are described. After a discussion of the technical and instrumental requirements and possibilities in the field of elementary particle research, the role and achievements of Hungarian scientists in high-energy facilities of the Soviet Union are emphasized.

    To discover what our world is made of and how it works at the most fundamental level is the challenge of particle physics. The tools of particle physics—experiments at particle accelerators and underground laboratories, together with observations of space—bring opportunities for discovery never before within reach. Thousands of scientists from universities and laboratories around the world collaborate to design, build and use unique detectors and accelerators to explore the fundamental physics of matter, energy, space and time. Together, in a common world-wide program of discovery, they provide a deep understanding of the world around us and countless benefits to society. Beacons of Discovery presents a vision of the global science of particle physics at the dawn of a new light on the mystery and beauty of the universe.

    The effect on mathematics of collaborations between high-energy theoretical physics and modern mathematics has been remarkable. Mirror symmetry has revolutionized enumerative geometry, and Seiberg-Witten invariants have greatly simplified the study of four manifolds. And because of their application to string theory, physicists now need to know cohomology theory, characteristic classes, index theory, K-theory, algebraic geometry, differential geometry, and non-commutative geometry. Much more is coming. We are experiencing a deeper contact between the two sciences, which will stimulate new mathematics essential to the physicists’ quest for the unification of quantum mechanics and relativity. Our grant, supported by the Department of Energy for twelve years, has been instrumental in promoting an effective interaction between geometry and string theory, by supporting the Mathematical Physics seminar, postdoc research, collaborations, graduate students and several research papers.

    The reason physicists have recently taken an intense interest in the statistical mechanics of certain lattice models is reviewed. Phase transitions in these systems are of direct relevance to whether the gauge theory of interacting quarks and gluons can prevent the quark as appearing as a free isolated object. Monte Carlo simulation techniques have given the strongest evidence for the confinement phenomenon and are beginning to make numerical predictions in strong interaction physics

    We study two arbitrary immiscible fuids where one phase contains small particles of the size of the interface and smaller. We primarily focus on charge-free particles with wetting characteristics described by the contact angle formed at the interface between the two phases and the particles. Based on the experimental observation that particles are adsorbed on the interface to reduce the interfacial energy and hence the surface tension as well, we formulate a free-energy functional that accounts for these physical effects. Using elements from calculus of variations and formal gradient flow theory, we derive partial differential equations describing the location of the interface and the density of the particles in the fluid phases. Via numerical experiments we analyse the time evolution of the surface tension, the particle concentration, and the free energy over time and reflect basic experimentally observed phenomena.

    To establish a common database on particle therapy for the evaluation of clinical studies integrating a large variety of voluminous datasets, different documentation styles, and various information systems, especially in the field of radiation oncology. We developed a web-based documentation system for transnational and multicenter clinical studies in particle therapy. 560 patients have been treated from November 2009 to September 2011. Protons, carbon ions or a combination of both, as well as a combination with photons were applied. To date, 12 studies have been initiated and more are in preparation. It is possible to immediately access all patient information and exchange, store, process, and visualize text data, any DICOM images and multimedia data. Accessing the system and submitting clinical data is possible for internal and external users. Integrated into the hospital environment, data is imported both manually and automatically. Security and privacy protection as well as data validation and verification are ensured. Studies can be designed to fit individual needs. The described database provides a basis for documentation of large patient groups with specific and specialized questions to be answered. Having recently begun electronic documentation, it has become apparent that the benefits lie in the user-friendly and timely workflow for documentation. The ultimate goal is a simplification of research work, better study analyses quality and eventually, the improvement of treatment concepts by evaluating the effectiveness of particle therapy

Some special highlights of this past year which are discusses in more detail in this report are: (1) The move onto beamline and start of ZEUS data taking. (2) The completion of the SDC technical proposal including a detailed long-term plan for construction. (3) Continuing publication of very detailed physics results from ALEPH concerning τ and b physics, and a precision measurement of electroweak and QCD parameters. (4) Completion of very successful data taking for E-791 at Fermilab, with nearly twice as many events recorded as initially proposed. (5) First measurement of beam polarization at the SLC. These efforts have led to about 15 physics publications this past year centered mainly on topics related to QCD, couplings of flavors to the Z degrees, and heavy flavor decays. Taken as a whole, the results in jets from LEP, the ratio of hadronic to leptonic decays of the τ the leptonic branching fraction of the J/ψ, and the charmonium mass spectrum provide a very consistent set of values of α s at a variety of scales. In particular, they show the running of α s by a factor of about three from m r to m z . Results from LEP also provide evidence of the triple gluon vertex. Similarly, the measurement of the b bar b fraction of Z degrees decays, from the MARK II as well as LEP, provide increasingly better measurements of the Z degree coupling to b quarks. Combined with earlier precision measurements of the Z degrees mass, width, and leptonic branching fractions, the Z degrees decays continue to provide a very precise verification of the Standard Model

    Following a suggestion by CERN Director General Herwig Schopper, this special issue of the CERN Courier covers the growing interplay between high energy physics and industrial high technology. Contributions from major Laboratories indicate the range of development partnerships now underway, but are by no means exhaustive - in particular work on cryogenics and superconductivity, on fast electronics, on photoelectronics, on computers, on ultra high vacuum, on data communications, ... is pushing ahead in parallel at several research centres, particularly at the major Laboratories such as CERN.

  12. Particle Physics at the Cosmic, Intensity, and Energy Frontiers

    2018-04-06

    Major efforts at the Intensity, Cosmic, and Energy frontiers of particle physics are rapidly furthering our understanding of the fundamental constituents of Nature and their interactions. The overall objectives of this research project are (1) to interpret and develop the theoretical implications of the data collected at these frontiers and (2) to provide the theoretical motivation, basis, and ideas for new experiments and for new analyses of experimental data. Within the Intensity Frontier, an experimental search for a new force mediated by a GeV-scale gauge boson will be carried out with the $A'$ Experiment (APEX) and the Heavy Photon Search (HPS), both at Jefferson Laboratory. Within the Cosmic Frontier, contributions are planned to the search for dark matter particles with the Fermi Gamma-ray Space Telescope and other instruments. A detailed exploration will also be performed of new direct detection strategies for dark matter particles with sub-GeV masses to facilitate the development of new experiments. In addition, the theoretical implications of existing and future dark matter-related anomalies will be examined. Within the Energy Frontier, the implications of the data from the Large Hadron Collider will be investigated. Novel search strategies will be developed to aid the search for new phenomena not described by the Standard Model of particle physics. By combining insights from all three particle physics frontiers, this research aims to increase our understanding of fundamental particle physics.

  13. Particle physics after the Higgs discovery: Philosophical perspectives

    Friederich, Simon; Lehmkuhl, Dennis

    2015-08-01

    The recent discovery at the LHC of a particle with properties matching those expected of the Higgs boson is a decisive event in the history of particle physics. The present special section combines three contributions that approach conceptual and methodological challenges related to this event and the current situation in particle physics from different angles. One contribution studies the experimental practices of contemporary particle physics by investigating the role of computer simulations in these practices; in particular, it focuses on the status of simulations as compared to experiments that in some circumstances have analogous functions. One contribution investigates the status of the controversial naturalness problem that many physicists see as the most severe shortcoming of the Standard Model of elementary particle physics. Finally, a third contribution critically assesses the impact of suggested no-go theorems concerning the interpretability of rigorous algebraic quantum field theory in terms of particles at the phenomenological level. In what follows we present a short overview of these contributions, highlighting some of their central ideas and arguments and putting them into context.

    2002-01-01

    Wigner's irreducible positive energy representations of the Poincare group are often used to give additional justifications for the Lagrangian quantization formalism of standard QFT. Here we study another more recent aspect. We explain in this paper modular concepts by which we are able to construct the local operator algebras for all standard positive energy representations directly without going through field coordinations. In this way the artificial emphasis on Lagrangian field coordinates is avoided from the very beginning. These new concepts allow to treat also those cases of 'exceptional' Wigner representations associated with anyons and the famous Wigner spin tower which have remained inaccessible to Lagrangian quantization. Together with the d=1+1 factorizing models (whose modular construction has been studied previously), they form an interesting family of theories with a rich vacuum-polarization structure (but no on shell real particle creation) to which the modular methods can be applied for their explicit construction. We explain and illustrate the algebraic strategy of this construction. We also comment on possibilities of formulating the Wigner theory in a setting of a noncommutativity. (author)

    urban areas of Finland, Sweden, Denmark, Germany, Italy, Spain, and Greece, between 1999 and 2013. We applied city-specific time-series Poisson regression models and pooled them with random-effects meta-analysis. RESULTS: We estimated a weak, delayed association between particle number concentration...... and particulate matter (PM) and daily mortality in eight European urban areas. METHODS: We collected daily data on non-accidental and cardio-respiratory mortality, particle number concentrations (as proxy for ultrafine particle number concentration), fine and coarse PM, gases and meteorologic parameters in eight...... and non-accidental mortality, with mortality increasing by approximately 0.35% per 10,000 particles/cm increases in particle number concentration occurring 5 to 7 days before death. A similar pattern was found for cause-specific mortality. Estimates decreased after adjustment for fine particles (PM2...

    A low fitness status during childhood and adolescence is associated with important health-related outcomes, such as increased future risk for obesity and cardiovascular diseases, impaired skeletal health, reduced quality of life and poor mental health. Fitness reference values for adolescents from different countries have been published, but there is a scarcity of reference values for pre-pubertal children in Europe, using harmonised measures of fitness in the literature. The IDEFICS study offers a good opportunity to establish normative values of a large set of fitness components from eight European countries using common and well-standardised methods in a large sample of children. Therefore, the aim of this study is to report sex- and age-specific fitness reference standards in European children. Children (10,302) aged 6-10.9 years (50.7% girls) were examined. The test battery included: the flamingo balance test, back-saver sit-and-reach test (flexibility), handgrip strength test, standing long jump test (lower-limb explosive strength) and 40-m sprint test (speed). Moreover, cardiorespiratory fitness was assessed by a 20-m shuttle run test. Percentile curves for the 1st, 3rd, 10th, 25th, 50th, 75th, 90th, 97th and 99th percentiles were calculated using the General Additive Model for Location Scale and Shape (GAMLSS). Our results show that boys performed better than girls in speed, lower- and upper-limb strength and cardiorespiratory fitness, and girls performed better in balance and flexibility. Older children performed better than younger children, except for cardiorespiratory fitness in boys and flexibility in girls. Our results provide for the first time sex- and age-specific physical fitness reference standards in European children aged 6-10.9 years.

    2018-01-01

    This textbook fills the gap between the very basic and the highly advanced volumes that are widely available on the subject. It offers a concise but comprehensive overview of a number of topics, like general relativity, fission and fusion, which are otherwise only available with much more detail in other textbooks. Providing a general introduction to the underlying concepts (relativity, fission and fusion, fundamental forces), it allows readers to develop an idea of what these two research fields really involve. The book uses real-world examples to make the subject more attractive and encourage the use of mathematical formulae. Besides short scientists' biographies, diagrams, end-of-chapter problems and worked solutions are also included. Intended mainly for students of scientific disciplines such as physics and chemistry who want to learn about the subject and/or the related techniques, it is also useful to high school teachers wanting to refresh or update their knowledge and to interested non-experts.

    The particle physics community has over the last 15 years achieved so-called full green open access through the wide dissemination ofpreprints via arXiv, a central subject repository managed by Cornell University. However, green open access does not alleviate the economical difficulties of libraries as these still are expected to offer access to versions of record of the peer-reviewed literature. For this reason the particle physics community is now addressing the issue of gold open access by converting a set of the existing core journals to open access. A working party works now to bring together funding agencies, laboratories and libraries into a single consortium, called SCOAP3 (Sponsoring Consortium for Open access Publishing in Particle Physics). This consortium will engage with publishers towards building a sustainable model for open access publishing. In this model, subscription fees from multiple institutions are replaced with contracts with publishers of open access journals where the SCOAP3 consort...

    Military and social restrictions imposed on Japanese scientific research following the second world war made nuclear or particle physics experiments almost impossible. However, the (Japanese) theoretical achievements of the 1940s considerably buoyed this group, namely two-meson theory, super-many-time theory and covariant renormalization theory. Economic conditions were also difficult with high inflation throughout the 1950s. Printing and distribution problems and paper shortages reduced the circulation of scientific journals, but theoretical work progressed well even in isolation. Within Japan, a circular called Soyrushiron Kenkyu (elementary particle theory research) became a valuable medium for exchange of new ideas and information. A Research Institute for Fundamental Physics, the first of several Japanese research institutes, was opened at Kyoto University in 1953, when a major international conference was held there. The second half of the 1950s was a time of expansion and consolidation for particle physics in Japan. (UK)

    1981-01-01

    For the first time, the micrometeoroid experiment on board of Helios allowed the measurement of physical and chemical characteristics of interplanetary dust particles between 0.3AU and 1AU solar distance. During the first 10 orbits of Helios 1,235 impacts of micrometeoroids have been detected. 83 particles have been registered by the ecliptic sensor and 152 by the south sensor. Most of the particles detected by the ecliptic sensor had masses 10 -13 g -10 g and impacted the sensor from the apex direction. The particles observed by the south sensor had masses 10 -15 g -9 g and impacted the sensor from all directions with a slightly enhanced flux from solar direction. The average impact speed of particles with masses 10 -13 g -10 g was 15km/s. From 1AU to.3AU, the observed paritcle flux increased by a factor 5-10. The orbits of the registered particles are highly eccentric, e approx. >= 0.6, and some are hyperbolic. The mass spectra measured upon impact allow the classification of chondritic and iron-rich particles. Approx. 20% of the particles had low densities rho 3 . On 4 particles, a positive electric charge has been observed. (orig.) [de

  18. Physical aspects of heavy charged particle beams for radiotherapy

    International Nuclear Information System (INIS)

    Kawashima, Katsuhiro

    1989-01-01

    Physical properties of heavy ion beams are discussed to improve the physical dose distributions in view of radiotherapy. Preservation of the structural and functional integrity of adjacent normal tissue is required to achieve great probability of tumor control. This will be accomplished with the reduction of irradiated volume of normal tissues and with greater relative biological effectiveness (RBE) on tumor cells than that on surrounding normal cells. This suggests the use of heavy ion beams as new source of radiation that increases the therapeutic ratio. The basis of the improvement in the physical dose distribution by use of heavy charged particles is due to the finite range of the beams and to the less multiple coulomb scattering of the particles having a heavier atomic mass than proton. The depth dose distributions and dose profiles of heavy particle beams are discussed in this article. The lateral sharpness of heavy charged particles is comparable to the penumbra of high energy photon and electron beams and is not of clinical concern due to less coulomb scattering of heavy ions to lateral direction in traversing a medium. The dose gradient at the end of range of primary beam is dependent upon the energy spread and range straggling of the particles. The magnitude of range straggling is nearly proportional to the range and inversely proportional to the inverse square root of the particle mass. Heavy ion beams also undergo nuclear interactions, in which the primary beam may produce lower atomic number particles. Therefore, the dose beyond the Bragg peak is due to those fragments. Fragmentation increases as a function of the atomic mass to the 2/3 power and with the energy of the particles. Thus, the production of fragments diminishes the depth dose advantages of heavy ions. The choice of ion for radiotherapy may depend on evaluation of important parameter for tumor control. (J.P.N.)

    2006-01-01

    A meeting has been called at CERN on November 3rd 2006 to work towards establishing a consortium of major particle physics funding agencies, aimed at guiding a transition of the current subscription model for journals to a more stable, more competitive and more affordable future for the dissemination of quality-assured scientific information adapted to the era of electronic publishing. The meeting will gather representatives of major European particle physics agencies and library consortia. In order to be successful it is vital that the stakeholders, representing as they do the funding bodies and academia, see themselves responsible for the financing and organization of the dissemination of scientific information and its quality assurance. In particular the transition to a wider availability of research results cannot afford to be held back due to a lack of concerted effort among the agencies financing the research.

  20. Scientific realism in particle physics a causal approach

    CERN Document Server

    Egg, Matthias

    2014-01-01

    Does particle physics really describe the basic constituents of the material world or is it just a useful tool for deriving empirical predictions? This book proposes a novel answer to that question, emphasizing the importance of causal reasoning for the justification of scientific claims. It thereby responds to general worries about scientific realism as well as to more specific challenges stemming from the interpretation of quantum physics.

  2. Quarks and gluons in nuclear and particle physics

    International Nuclear Information System (INIS)

    Van Hove, L.

    1988-01-01

    This paper provides a broad overview of strong interactions, or nuclear forces, as ones understanding has expanded over the past 25 years. The major particles and models are briefly touched upon. The author expands upon the field theories which have evolved to explain the experimental work, and the present model of quarks and gluons which form the components of hadrons. The standard model has been very successful in explaining much of the newly acquired experimental data. But the property of confinement, where the partons, (quarks and gluons), are not observed seperately has precluded observation of these particles. He touches on the manifestation of these particles in high energy physics, where they model the observed particles and resonances, and are responsible for the production of hadronic jets. However in nuclear physics, one does not need to postulate the existance of these particles to explain the properties of nuclei, until one deals with interaction energies in the range of GeV. The author then touches on the area of ultra-relativistic nuclear physics, where the partons must play a role in the effects which are observed. In particular he discusses deep inelastic lepton scattering on nuclei, the Drell-Yan process in nuclei, and ultra-relativistic nuclear collisions. Finally he gives a brief discussion of the quark-gluon plasma, which is postulated to form during very high energy collisions, manifesting itself as a brief deconfinement of the partons into an equilibrium plasma

    Particle therapy (PT) as cancer treatment, using protons or heavier ions, can provide a more favorable dose distribution compared to X-rays. While the physical characteristics of particle radiation have been the aim of intense research, less focus has been placed on the actual biological responses arising from particle irradiation. One of the biggest challenges for proton radiobiology is the RBE, with an increasing concern that the clinically-applied generic RBE-value of 1.1 is an approximation, as RBE is a complex quantity, depending on both biological and physical parameters, such as dose, LET, cellular and tissue radiobiological characteristics, as well as the endpoints being studied. Most of the available RBE data derive from in vitro experiments, with very limited in vivo data available, especially in late-reacting tissues, which provide the main constraints and influence the quality of life endpoints in radiotherapy. There is a need for systematic, large-scale studies to thoroughly establish the biology of particle radiation in a number of different experimental models in order to refine biophysical mathematical models that can potentially be used to guide PT. The overall objective of the European Particle Therapy Network (EPTN) WP6 is to form a network of research and therapy facilities in order to coordinate and standardize the radiobiological experiments, to obtain more accurate predictive parameters than in the past. Coordinated research is required in order to obtain the most appropriate experimental data. The aim in this paper is to describe the available radiobiology infrastructure of the centers involved in EPTN WP6. Copyright © 2018 Elsevier B.V. All rights reserved.

    The fourth international conference on Particle and Fundamental Physics in Space (SpacePart12) will take place at CERN from 5 to 7 November. The conference will bring together scientists working on particle and fundamental physics in space and on ground, as well as space policy makers from around the world.   One hundred years after Victor Hess discovered cosmic rays using hot air balloons, the experimental study of particle and fundamental physics is still being pursued today with extremely sophisticated techniques: on the ground, with state-of-the-art accelerators like the LHC; and in space, with powerful observatories that probe, with amazing accuracy, the various forms of cosmic radiation, charged and neutral, which are messengers of the most extreme conditions of matter and energy. SpacePart12 will be the opportunity for participants to exchange views on the progress of space-related science and technology programmes in the field of particle and fundamental physics in space.

    Peschanski, R.

    1991-01-01

    Some features and theoretical interpretations of the intermittency phenomenon observed in high-energy multi-particle production are recalled. One develops on the various connections found with fractal structuration of fluctuations in turbulence, spin-glass physics and aggregation phenomena described by the non-linear Smoluchowski equation. This may lead to a new approach to quantum field properties

  20. Particles and Nuclei an introduction to the physical concepts

    CERN Document Server

    Povh, B; Scholz, C; Zetsche, F

    2008-01-01

    This well-established textbook gives a uniform and unique presentation of both nuclear and particle physics. Analysis, Part 1, is devoted to disentangling the substructure of matter. This part shows that experiments designed to uncover the substructures of nuclei and nucleons have a similar conceptual basis, and lead to the present picture of all matter being built out of a small number of elementary building blocks and a small number of fundamental interactions. Synthesis, Part 2, shows how the elementary particles may be combined to build hadrons and nuclei. The fundamental interactions responsible for the forces in all systems become less and less evident in increasingly complex systems. A section on neutrino oscillations and one on nuclear matter at high temperatures bridge the field of "nuclear and particle physics" and "modern astrophysics and cosmology". The new edition incorporates a large amount of new experimental results on deep inelastic scattering (obtained at the Electron-Proton Collider HERA at...
