    We study the one-loop new physics effects to the CP even triple neutral gauge boson vertices γ * γZ, γ * ZZ, Z * Zγ and Z * ZZ in the context of Little Higgs models. We compute the contribution of the additional fermions in Little Higgs models in the framework of direct product groups where [SU(2) x U(1)] 2 gauge symmetry is embedded in SU(5) global symmetry and also in the framework of the simple group where SU(N) x U(1) gauge symmetry breaks down to SU(2) L x U(1). We calculate the contribution of the fermions to these couplings when T parity is invoked. In addition, we re-examine the MSSM contribution at the chosen point of SPS1a ' and compare with the SM and Little Higgs models. (orig.)

    2012-01-01

    A complete list of operators contributing at the lowest order to Quartic Neutral Gauge Boson Couplings involving photons and Z-bosons, is presented. We show that, for the couplings we consider, the lowest order contribution is from dimension 8 operators in the case when a light Higgs is present and from dimension 6 operators in the higgsless case where electroweak symmetry is non-linearly realized. We also show that these operators are generated by exchange of the Kaluza-Klein partners of the graviton in extra-dimensional models. We then explore the possibility of probing these couplings in the diffractive photon fusion processes pp(\\gamma\\gamma \\to \\gamma\\gamma)pp and pp(\\gamma\\gamma \\to ZZ)pp at the 14 TeV LHC. We find that the \\gamma \\gamma \\gamma \\gamma-coupling can be probed most sensitively and values as small as 1/(1.8 TeV)^{4} can be measured. For the \\gamma\\gamma ZZ-coupling, values as small as 1/(850 GeV)^{4} and 1/(1.9 TeV)^2 can be probed in the light Higgs and higgsless cases respectively, which ...

    2007-01-01

    This thesis reports on techniques and the corresponding phenomenology for distinguishing between models in the analysis of new neutral gauge boson production at the LHC. Specifically, third generation final states are reviewed and determined to be effective channels for analysis. Transverse momentum cuts of pxf > 0.3 Mz> to hadronic final states are employed to reduce QCD backgrounds and distinguish t and b signals. An analysis of the ratio of the t and b cross sections to the fi cross section, within an invariant mass window of 0.965 Mz> , is performed. For final state fermion detection efficiencies of = 0.96, et = 0.10, and e*, = 0.50, most models considered can be distinguished by at least one standard deviation for Mz> = 1500 GeV, with 10 fb_1 integrated luminosity. Furthermore, the ratio of the t to cross sections is analyzed and used to understand models with preferential couplings to third generation particles in the lepton family. Assuming an efficiency of er = 0.2, generation universality can be dete...

  8. Spectroscopy of family gauge bosons

    2014-09-01

    Full Text Available Spectroscopy of family gauge bosons is investigated based on a U(3 family gauge boson model proposed by Sumino. In his model, the family gauge bosons are in mass eigenstates in a diagonal basis of the charged lepton mass matrix. Therefore, the family numbers are defined by (e1,e2,e3=(e,μ,τ, while the assignment for quark sector are free. For possible family-number assignments (q1,q2,q3, under a constraint from K0–K¯0 mixing, we investigate possibilities of new physics, e.g. production of the lightest family gauge boson at the LHC, μ−N→e−N, rare K and B decays, and so on.

  9. Colored pseudo Goldstone bosons and gauge boson pairs

    If the electroweak symmetry breaking sector contains colored particles weighing a few hundred GeV, then they will be copiously produced at a hadron supercollider. Colored technipions can rescatter into pairs of gauge bosons. As proposed by Bagger, Dawson, and Valencia, this leads to gauge boson pair rates far larger than in the standard model. In this Letter we reconsider this mechanism, and illustrate it in a model in which the rates can be reliably calculated. The observation of both an enhanced rate of gauge-boson-pair events and colored particles would be a signal that the colored particles were pseudo Goldstone bosons of symmetry breaking

  11. Strong gauge boson scattering at the LHC

    CERN Document Server

    Rindani, S.D.

    2009-01-01

    In the standard model with electroweak symmetry breaking through the Higgs mechanism, electroweak gauge-boson scattering amplitudes are large if the Higgs boson is heavy, and electroweak gauge interactions become strong. In theories with electroweak symmetry breaking through alternative mechanisms, there could be a strongly interacting gauge sector, possibly with resonances in an accessible energy region. In general, the scattering of longitudinally polarized massive gauge bosons can give information on the mechanism of spontaneous symmetry breaking. At energies below the symmetry breaking scale, the equivalence theorem relates the scattering amplitudes to those of the "would-be" Goldstone modes. In the absence of Higgs bosons, unitarity would be restored by some new physics which can be studied through WW scattering. Some representatives models are discussed. Isolating WW scattering at a hadron collider from other contributions involving W emission from parton lines needs a good understanding of the backgrou...

    2014-01-01

    We overview the dark parity violation, which means the parity violation induced by a dark gauge boson of very small mass and coupling. When a dark gauge boson has an axial coupling, as in dark Z model, it can change the effective Weinberg angle in the low-energy experiments such as the atomic parity violation and the low-Q^2 polarized electron scatterings. Such low-energy parity tests are an excellent probe of the dark force.

  15. Search for new heavy charged gauge bosons

    Magass, Carsten Martin [RWTH Aachen Univ. (Germany)

    2007-11-02

    Additional gauge bosons are introduced in many theoretical extensions to the Standard Model. A search for a new heavy charged gauge boson W' decaying into an electron and a neutrino is presented. The data used in this analysis was taken with the D0 detector at the Fermilab proton-antiproton collider at a center-of-mass energy of 1.96 TeV and corresponds to an integrated luminosity of about 1 fb-1. Since no significant excess is observed in the data, an upper limit is set on the production cross section times branching fraction σW'xBr (W' → ev). Using this limit, a W' boson with mass below ~1 TeV can be excluded at the 95% confidence level assuming that the new boson has the same couplings to fermions as the Standard Model W boson.

    2006-01-01

    Interactions among the standard model gauge bosons and scalar fields in the framework of the SU(3) C xSU(3) L xU(1) X gauge model with minimal (economical) Higgs content are presented. From these couplings, all scalar fields including the neutral scalar h and the Goldstone bosons can be identified and their couplings with the usual gauge bosons such as the photon, the charged W ± , and the neutral Z, without any additional conditions, are recovered. In the effective approximation, the full content of the scalar sector can be recognized. The CP-odd part of the Goldstone associated with the neutral non-Hermitian bilepton gauge boson G X 0 is decoupled, while its CP-even counterpart has the mixing in the same way in the gauge boson sector. Masses of the new neutral Higgs boson H 1 0 and the neutral non-Hermitian bilepton X 0 are dependent on a coefficient of Higgs self-coupling (λ 1 ). Similarly, masses of the singly charged Higgs boson H 2 ± and of the charged bilepton Y ± are proportional through a coefficient of Higgs self-interaction (λ 4 ). The hadronic cross section for production of this Higgs boson at the CERN LHC in the effective vector boson approximation is calculated. Numerical evaluation shows that the cross section can exceed 260 fb

    We report the results of a search for a heavy neutral gauge boson Z' decaying into the dielectron final state using data corresponding to an integrated luminosity of 5.4 fb{sup -1} collected by the D0 experiment at the Fermilab Tevatron Collider. No significant excess above the standard model prediction is observed in the dielectron invariant-mass spectrum. We set 95% C.L. upper limits on {sigma}(p{bar p} {yields} Z') x BR(Z' {yields} ee) depending on the dielectron invariant mass. These cross section limits are used to determine lower mass limits for Z' bosons in a variety of models with standard model couplings and variable strength.

  20. Flavour-changing neutral currents in models with extra Z' boson

    2004-01-01

    New neutral gauge bosons Z' are the features of many models addressing the physics beyond the standard model. Together with the existence of new neutral gauge bosons, models based on extended gauge groups (rank > 4) often predict new charged fermions also. A mixing of the known fermions with new states, with exotic weak-isospin assignments (left-handed singlets and right-handed doublets) will induce tree-level flavour-changing neutral interactions mediated by Z exchange, while if the mixing is only with new states with ordinary weak-isospin assignments, the flavour-changing neutral currents are mainly due to the exchange of the new neutral gauge boson Z'. We review flavour-changing neutral currents in models with extra Z' boson. Then we discuss some flavour-changing processes forbidden in the standard model and new contributions to standard model processes. (author)

    The TEVATRON proton-antiproton collider at FERMILAB (near Chicago/USA) is operating at a center-of-mass energy of {radical}(s)=1.96 TeV since March 2001. This analysis uses data taken with the DOe detector until February 2006 corresponding to an integrated luminosity of about {integral}Ldt=1 fb{sup -1}. Using this dataset, a search for a new heavy charged gauge boson W{sup '} and its subsequent decay into an electron and a neutrino is performed: p anti p{yields}W{sup '}+X{yields}e{nu}+X. Additional gauge bosons (including the equivalent to the Z, the Z{sup '}) are introduced in many extensions to the Standard Model of particle physics. Assuming the most general case, the new gauge group can comprise a new mixing angle and new couplings. Here, the Altarelli Reference Model is considered which represents a generalization of the Manifest Left-Right Symmetric Model with light right-handed neutrinos. This model makes the assumptions that the new gauge boson W{sup '} has the same couplings as the Standard Model W boson and that there is no mixing. Hence, the W{sup '} is a heavy copy of the Standard Model W boson. The clear decay signature (in analogy to the decay of the W) contains an isolated electron with extreme high energy which is important for triggering. The neutrino can not be detected, but it gives rise to missing energy in the detector. The Jacobian peak in the transverse mass distribution stemming from the W decay is used for calibration, whereas the tail of the transverse mass distribution is searched for a possible W{sup '} signal. The data agrees with the expectation from background processes. For instance, in the data 37 events are reconstructed with transverse masses above 300 GeV compared to a prediction of 37.1{+-}2.1(stat){sup +6.0}{sub -3.7}(sys) background events. Since no significant excess is found in the data, an upper limit is set on the production cross section for heavy charged gauge bosons decaying into electron

    The TEVATRON proton-antiproton collider at FERMILAB (near Chicago/USA) is operating at a center-of-mass energy of √(s)=1.96 TeV since March 2001. This analysis uses data taken with the DOe detector until February 2006 corresponding to an integrated luminosity of about ∫Ldt=1 fb -1 . Using this dataset, a search for a new heavy charged gauge boson W ' and its subsequent decay into an electron and a neutrino is performed: p anti p→W ' +X→eν+X. Additional gauge bosons (including the equivalent to the Z, the Z ' ) are introduced in many extensions to the Standard Model of particle physics.

Using this limit, a lower bound on the mass of the new gauge

  3. Higgs-boson contributions to gauge-boson mass shifts in extended electroweak models

    In the minimal standard model, the difference between the tree-level and one-loop-corrected predictions for the gauge-boson masses, known as the mass shifts, are of the order of 4%. The dominant contribution is from light-fermion loops. The Higgs-dependent terms are small, even if the Higgs boson is heavy. We have analyzed the mass shifts for models with a more complicated Higgs sector. We use the on-shell renormalization scheme, in which the parameters of the theory are the physical masses and couplings. We have considered the 2-doublet, n-doublet, triplet and doublet-triplet models. We have found that the Z-boson mass prediction has a strong dependence on the charged-Higgs mass. In the limit that the charged Higgs is much heavier than the gauge bosons, the Higgs-dependent terms become significant, and may even cancel the light-fermion terms. In the models with a Higgs triplet, there is also a strong dependence on the neutral-Higgs masses, although this contribution tends to be suppressed in realistic models. The W-boson mass shift does not have a strong Higgs dependence. If we use the Z mass as input in determining the parameters of the theory, a scenario which will become attractive as the mass of the Z is accurately measured in the next few years, we find that the W-boson mass shift exhibits the same sort of behavior, differing from the minimal model for the case of the charged Higgs being heavy. We have found that when radiative corrections are taken into account, models with extended Higgs sectors may differ significantly from the minimal standard model in their predictions for the gauge-boson masses. Thus, an accurate measurement of the masses will help shed light on the structure of the Higgs sector. 68 refs

  4. Search for Additional Heavy Neutral Higgs and Gauge Bosons with LHC Run 2 data in the $\\tau\\tau$ final state with the ATLAS detector

    CERN Document Server

    Bailey, Adam; The ATLAS collaboration

    2017-01-01

    A search for heavy neutral Higgs and Z' bosons in the $\\tau\\tau$ channel is presented from data collected by the ATLAS detector in 2015 and 2016. The total data sample corresponds to an integrated luminosity of 36.1 fb$^{-1}$. The search is performed in two channels; both $\\tau$ decay hadronically, or one $\\tau$ decaying leptonically and one hadronically. Data are in good agreement with the standard model. Results are interpreted as limits on the cross section times branching fraction. Model-specific limits are presented in the $\\tan\\beta-m_{h}$ plane for two benchmark scenarios, hMSSM and $m_{h}^{mod+}$. For the Z' search results are interpreted using the Sequential Standard Model and non-universal G(221) model.

  5. Neutral Supersymmetric Higgs Boson Searches

    Robinson, Stephen Luke [Imperial College, London (United Kingdom)

    2008-07-01

    In some Supersymmetric extensions of the Standard Model, including the Minimal Supersymmetric Standard Model (MSSM), the coupling of Higgs bosons to b-quarks is enhanced. This enhancement makes the associated production of the Higgs with b-quarks an interesting search channel for the Higgs and Supersymmetry at D0. The identification of b-quarks, both online and offline, is essential to this search effort. This thesis describes the author's involvement in the development of both types of b-tagging and in the application of these techniques to the MSSM Higgs search. Work was carried out on the Level-3 trigger b-tagging algorithms. The impact parameter (IP) b-tagger was retuned and the effects of increased instantaneous luminosity on the tagger were studied. An extension of the IP-tagger to use the z-tracking information was developed. A new b-tagger using secondary vertices was developed and commissioned. A tool was developed to allow the use of large multi-run samples for trigger studies involving b-quarks. Offline, a neural network (NN) b-tagger was trained combining the existing offline lifetime based b-tagging tools. The efficiency and fake rate of the NN b-tagger were measured in data and MC. This b-tagger was internally reviewed and certified by the Collaboration and now provides the official b-tagging for all analyses using the Run IIa dataset at D0. A search was performed for neutral MSSM Higgs bosons decaying to a b{bar b} pair and produced in association with one or more b-quarks. Limits are set on the cross-section times the branching ratio for such a process. The limits were interpreted in various MSSM scenarios. This analysis uses the NN b-tagger and was the first to use this tool. The analysis also relies on triggers using the Level-3 IP b-tagging tool described previously. A likelihood discriminant was used to improve the analysis and a neural network was developed to cross-check this technique. The result of the analysis has been submitted to PRL

    We investigate collider signals for gauged flavor symmetries that have been proposed in models of dynamical electroweak symmetry breaking and fermion mass generation. We consider the limits on the masses of the gauge bosons in these models which can be extracted from Fermilab Tevatron run I data in dijet production. Estimates of the run II search potential are provided. We show that the models also give rise to significant signals in single top quark production which may be visible at run II. In particular we study chiral quark family symmetry and SU(9) chiral flavor symmetry. The run I limits on the gauge bosons in these models lie between 1.5 and 2 TeV and should increase to about 3 TeV in run II. Finally, we show that an SU(12) enlargement of the SU(9) model, including leptonic interactions, is constrained by low energy atomic parity violation experiments to lie outside the reach of the Tevatron.

    We present an application of the equivalence theorem and the multispinor representation of gauge fields to the standard model of electroweak interactions at very high energies. The equivalence theorem allows us to efficiently treat the longitudinal vector bosons while the multispinor formalism makes the transverse vector bosons easy to handle. We generalize the work of Berends and Giele to derive a recursion relation for a current consisting of a pair of longitudinal vector bosons plus any number of transverse vector bosons. It is shown that for longitudinal vector bosons plus any number of transverse vector bosons. Consideration of a U(N), rather than an SU(N), gauge theory enables us to incorporate the mixing in the SU(2)xU(1) electroweak theory and to derive certain sum rules for the currents for transverse gauge bosons. We also give explicit expressions for four-particle and five-particle scattering amplitudes involving a pair of longitudinal vector bosons. (orig.)

    The chiral bosonization in non-Abelian gauge theories is described starting directly from the QCD functional. For a given mass scale Λ, the QCD may be equivalently represented by colour chiral fields, gauge fields and high energy fermions. The effective action for colour chiral fields may admit the existence of a colour Skyrmion-boson with the baryon number 2/3. (author)

    Full Text Available We show that the mixed gravitational/gauge superstring amplitudes describing decays of massless closed strings – gravitons or dilatons – into a number of gauge bosons, can be written at the tree (disk level as linear combinations of pure open string amplitudes in which the graviton (or dilaton is replaced by a pair of collinear gauge bosons. Each of the constituent gauge bosons carry exactly one half of the original closed string momentum, while their ±1 helicities add up to ±2 for the graviton or to 0 for the dilaton.

  12. A screening mechanism for extra W and Z gauge bosons

    Matias, J

    2000-01-01

    We generalize a previous construction of a fermiophobic model to the case of more than one extra W and Z gauge bosons. We focus in particular on the existence of screening configurations and their implication on the gauge boson mass spectrum. One of these configurations allows for the existence of a set of relatively light new gauge bosons, without violation of the quite restrictive bounds coming from the rho /sub NC/ parameter. The links with Bess and degenerate Bess models are also discussed. Also the signal given here by this more traditional gauge extension of the SM could help to disentangle it from the towers of Kaluza-Klein states over W and Z gauge bosons in extra dimensions.

    Measurements of the cross sections of the production of three electroweak gauge bosons and of vector-boson scattering processes at the LHC constitute stringent tests of the electroweak sector of the Standard Model and provide a model-independent means to search for new physics at the TeV scale. The ATLAS collaboration searched for the production of three W bosons or of a W boson and a photon together with a Z or W boson at a center of mass energy of 8 TeV. ATLAS has also searched for the electroweak production of a heavy boson and a photon together with two jets. Evidence has been found for the exclusive production of W boson pairs. All results have been used to constrain anomalous quartic gauge couplings and have been compared to the latest theory predictions.

    Full Text Available We present results for the polarisation of gauge bosons produced at the LHC. Polarisation effects for W bosons manifest themselves in the angular distributions of the lepton and in the distributions of lepton transverse momentum and missing transverse energy. The polarisation is discussed for a range of different processes producing W bosons such as W+jets and W from top production. The relative contributions of the different polarisation states vary from process to process, reflecting the dynamics of the underlying hardscattering process. We also calculate the polarisation of the Z boson produced in association with QCD jets at the LHC.

    We calculate the leading-order scattering amplitude of one vector and two tensor gauge bosons in a recently proposed non-Abelian tensor gauge field theory and open superstring theory. The linear in momenta part of the superstring amplitude has identical Lorentz structure with the gauge theory, while its cubic in momenta part can be identified with an effective Lagrangian which is constructed using generalized non-Abelian field strength tensors.

    Collider searches for energetic particles recoiling against missing transverse energy allow to place strong bounds on the interactions between dark matter (DM) and standard model particles. In this article we update and extend LHC constraints on effective dimension-7 operators involving DM and electroweak gauge bosons. A concise comparison of the sensitivity of the mono-photon, mono-W, mono-Z, mono-W/Z, invisible Higgs-boson decays in the vector boson fusion mode and the mono-jet channel is presented. Depending on the parameter choices, either the mono-photon or the mono-jet data provide the most stringent bounds at the moment. We furthermore explore the potential of improving the current 8 TeV limits at 14 TeV. Future strategies capable of disentangling the effects of the different effective operators involving electroweak gauge bosons are discussed as well.

    It was shown that in a free anyon gas there exists a composite vector gauge field with the effective action containing a Chern-Simons term. The momentum dependence of the energy of the composite boson was found. The mixing between Chern-Simons boson and photon gives rise to the appearance of new quasiparticles - Chern-Simons polaritons. The dispersion equations of Chern-Simons polaritons were derived. (author). 14 refs

    A critical prediction of the Standard Model electroweak theory is the existence of triple and quartic gauge-boson self-interactions. The 2010-12 LHC run has resulted in a wealth of data in this sector, which can now be probed in many different production modes, both ordinary and potentially anomalous, with a sensitivity that is world-leading. In this seminar, recent CMS results are presented for: measurements of diboson production, with associated constraints on triple gauge boson couplings; the first LHC measurement of purely electroweak production of a Z with two forward jets; and two-photon production of W pairs, with the first LHC constraints on quartic gauge couplings.

    A search for heavy neutral Higgs bosons and Z′ bosons is performed using a data sample corresponding to an integrated luminosity of 36.1 fb−1 from proton-proton collisions at s√ = 13 TeV recorded by the ATLAS detector at the LHC during 2015 and 2016. The heavy resonance is assumed to decay to τ+τ− with at least one tau lepton decaying to final states with hadrons and a neutrino. The search is performed in the mass range of 0.2-2.25 TeV for Higgs bosons and 0.2-4.0 TeV for Z′ bosons. The data are in good agreement with the background predicted by the Standard Model. The results are interpreted in benchmark scenarios. In the context of the hMSSM scenario, the data exclude tanβ>1.0 for mA = 0.25 TeV and tanβ>42 for mA = 1.5 TeV at the 95% confidence level. For the Sequential Standard Model, Z′SSM with mZ′<2.42 TeV is excluded at 95% confidence level, while Z′NU with mZ′<2.25 TeV is excluded for the non-universal G(221) model that exhibits enhanced couplings to third-generation fermion...

    A search for heavy neutral Higgs bosons and Z' bosons is performed using a data sample corresponding to an integrated luminosity of 36.1 fb-1 from proton-proton collisions at √{s}=13 TeV recorded by the ATLAS detector at the LHC during 2015 and 2016. The heavy resonance is assumed to decay to τ + τ - with at least one tau lepton decaying to final states with hadrons and a neutrino. The search is performed in the mass range of 0.2-2.25 TeV for Higgs bosons and 0.2-4.0 TeV for Z' bosons. The data are in good agreement with the background predicted by the Standard Model. The results are interpreted in benchmark scenarios. In the context of the hMSSM scenario, the data exclude tan β > 1 .0 for m A = 0 .25 TeV and tan β > 42 for m A = 1 .5 TeV at the 95% confidence level. For the Sequential Standard Model, Z SSM ' with m Z' Z NU ' with m Z ' generation fermions. [Figure not available: see fulltext.

  8. An effective theory of massive gauge bosons

    The coupling of a group-valued massive scalar field to a gauge field through a symmetric rank-2 field strenght is studied. By considering energies very small compared with the mass of the scalar and invoking the decoupling theorem, one is left with a low-energy effective theory describing a dynamics of massive vector fields.

    We present the results of searches for additional gauge bosons beyond the W and Z bosons using the 1992-1993 Tevatron data set collected with the D0 detector. The signatures studied are W' → eν, W' → τν with τ → eν bar ν, assuming stable neutrinos; W R → e + X and W R → eejj, assuming massive neutrinos; and Z' → ee. Lower limits on the W' mass and Z' mass at the 95% confidence level, and the mass exclusion contour in the W R mass vs. neutrino mass plane are presented

    After six years of data taking at Z peak, LEP beam energy continuously raised to finally reach 104.5 GeV, allowing notably W pairs production. Z resonance remains however important trough radiative return process; a hard photon being emitted in initial state, the centre of mass energy is reduced to an effective value close to Z mass. These events taken by Aleph experiment between 1998 and 2000 have been analysed following two distinct approaches, that are detailed in this thesis. With nearly 700 pb{sup -1} taken by each experiment, it is obvious that final W mass measurement- one major goal of LEP2 program- will be dominated by systematic error, with a large contribution from the uncertainty on the LEP beam energy. A fit of the radiative return peak position allows an original determination of the latter. Being not only a single measurement, this method is also a powerful tool to check techniques used in W mass measurement. Moreover, Z{gamma} events final states are similar to processes with a vertex involving three neutral gauge bosons. Anomalous production cross section, as well as deformed kinematic distributions, can be a probe of new physic that lies at much higher energy scales. A search for such phenomena has also been performed. (author)

  11. Muon g-2 Anomaly and Dark Leptonic Gauge Boson

    One of the major motivations to search for a dark gauge boson of MeV-GeV scale is the long-standing muon g-2 anomaly. Because of active searches such as fixed target experiments and rare meson decays, the muon g-2 favored parameter region has been rapidly reduced. With the most recent data, it is practically excluded now in the popular dark photon model. We overview the issue and investigate a potentially alternative model based on the gauged lepton number or U(1)_L, which is under different experimental constraints.

  12. Triple and quartic gauge boson couplings at the LHC

    2017-01-01

    This report at the conference Physics in Collision 2017 reviews recent results from the ATLAS and CMS experiments on production of gauge boson pairs, triples, and vector boson scattering (VBS) processes. Large datasets from LHC proton-proton collisions at $\\sqrt{s}=8$ and $13\\,\\mathrm{TeV}$ allowed the first observations of rare processes: triboson production in channel $Z\\gamma\\gamma$ at $\\sqrt{s}=8\\,\\mathrm{TeV}$ and VBS of same signed WW at $\\sqrt{s}=13\\,\\mathrm{TeV}$. Both experiments observe good agreement with the Standard model (SM) predictions. The data were used to set new limits on anomalous triple and quartic gauge couplings not present in the SM.

    Gauge boson production at forward rapidities in single diffractive events at the LHC is investigated considering pp collisions at √(s) = 8 and 13 TeV. The impact of gap survival effects is analysed using two different models for the soft rescattering contributions. We demonstrate that using the forward shower counter Project at LHCb-HERSCHEL, together with the Vertex Locator-VELO, it is possible to discriminate diffractive production of the gauge bosons W and Z from the non-diffractive processes and studies of the Pomeron structure and diffraction phenomenology are feasible. Moreover, we show that the analysis of this process can be useful to constrain the modelling of the gap survival effects. (orig.)

  14. Bosons on the Kagome lattice with artificial gauge fields

    We investigate bosons on the Kagome lattice subject to artificial gauge fields such that no net flux is applied on a unit cell. This allows for example the existence of quantized and non-quantized anomalous Hall effects on the Kagome lattice. If two layers or two-component bosons are introduced, the topological phase is robust to inter-species interactions of moderate strength. We study the conditions under which the total density degree of freedom undergoes a Mott transition, while the pseudo-spin, or charge difference between layers, is in a superfluid phase with topological properties. Similar results can be obtained for two-component bosons on the honeycomb lattice. Such systems could work as a template for the realization of interacting topological phases in cold atom or cavity QED systems.

  15. Search for a neutral Higgs boson

    International Nuclear Information System (INIS)

    Malmgren, T.G.M.

    1997-04-01

    The mass of the neutral Higgs boson cannot be predicted by models. Therefore, the particle is scanned for at different assumed masses. The search described here was done using data taken at the DELPHI detector in 1993. The Bjorken process was searched for where the decay of the Z 0* into two neutrinos was assumed. In order to reduce the background to a level where a discovery would be possible, an artificial feed-forward neural network was used. This led to a very good background rejection and high signal efficiency. An efficiency of around 30-50% was reached for a H 0 mass ranging from 35-60 GeV/c 2 leaving zero background events. One event was selected from the real data with a H 0 mass of 27.5(3.6) GeV/c 2 . These results were translated into a limit m H >58.3 GeV/c 2 at 95% confidence level

  17. Bounds on dark matter interactions with electroweak gauge bosons

    We investigate scenarios in which dark matter interacts with the Standard Model primarily through electroweak gauge bosons. We employ an effective field theory framework wherein the Standard Model and the dark matter particle are the only light states in order to derive model-independent bounds. Bounds on such interactions are derived from dark matter production by weak boson fusion at the LHC, indirect detection searches for the products of dark matter annihilation and from the measured invisible width of the Z 0 . We find that limits on the UV scale, Λ , reach weak scale values for most operators and values of the dark matter mass, thus probing the most natural scenarios in the weakly interacting massive particle dark matter paradigm. Our bounds suggest that light dark matter ( m χ ≲ m Z / 2 or m χ ≲ 100 – 200 GeV , depending on the operator) cannot interact only with the electroweak gauge bosons of the Standard Model, but rather requires additional operator contributions or dark sector structure to avoid overclosing the Universe.

  18. Higgs-boson contributions to gauge-boson mass shifts in extended electroweak models

    International Nuclear Information System (INIS)

    Moore, S.R.

    1985-01-01

    The author analyzed the mass shifts for models with a more complicated Higgs sector. He uses the on-shell renormalization scheme, in which the parameters of the theory are the physical masses and couplings. The author has considered the 2-doublet, n-doublet, triplet and doublet-triplet models. He has found that the Z-boson mass prediction has a strong dependence on the charged-Higgs mass. In the limit that the charged Higgs is much heavier than the gauge bosons, the Higgs-dependent terms become significant, and may even cancel the light-fermion terms. If the author uses the Z mass as input in determining the parameters of the theory, a scenario which will become attractive as the mass of the Z is accurately measured in the next few years, it is found that the W-boson mass shift exhibits the same sort of behavior, differing from the minimal model for the case of the charged Higgs being heavy. The author has found that when the radiative corrections are taken into account, models with extended Higgs sectors may differ significantly from the minimal standard model in this predictions for the gauge-boson masses. Thus, an accurate measurement of the masses will help shed light on the structure of the Higgs sector

  19. Muon-Electron Conversion in a Family Gauge Boson Model

    We study the $\\mu$-$e$ conversion in muonic atoms via an exchange of family gauge boson (FGB) $A_{2}^{\\ 1}$ in a $U(3)$ FGB model. Within the class of FGB model, we consider three types of family-number assignments for quarks. We evaluate the $\\mu$-$e$ conversion rate for various target nuclei, and find that next generation $\\mu$-$e$ conversion search experiments can cover entire energy scale of the model for all of types of the quark family-number assignments. We show that the conversion rat...

    The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric Standard Model (MSSM). The data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and with a possible Higgs boson signal. The combined LEP data show no significant excess of events which would indicate the production of Higgs bosons. The search results are used to set upper bounds on the cross-sections of various Higgs-like event topologies. The results are interpreted within the MSSM in a number of ``benchmark" models, including CP-conserving and CP-violating scenarios. These interpretations lead in all cases to large exclusions in the MSSM parameter space. Absolute limits are set on the parameter tanb and, in some scenarios, on the masses of neutral Higgs bosons.

    A flavour independent search for the CP-even and CP-odd neutral Higgs bosons h and A is performed in 624/pb of data collected with the L3 detector at LEP at centre-of-mass energies between 189 and 209GeV. Higgs boson production through the e^+e^- -> Z h and the e^+e^- ->h A processes is considered and decays of the Higgs bosons into hadrons are studied. No significant signal is observed and 95% confidence level limits on the hZZ and hAZ couplings are derived as a function of the Higgs boson masses. Assuming the Standard Model cross section for the Higgs-strahlung process and a 100% branching fraction into hadrons, a 95% confidence level lower limit on the mass of the Higgs boson is set at 110.3GeV.

  2. Anomalous U(1), Gauge-Mediated Supersymmetry Breaking and Higgs as Pseudo-Goldstone Bosons

    We study the breaking of supersymmetry in models with anomalous U(1). These models are simple to construct and contain natural candidates for being the messengers of gauge-mediated supersymmetry breaking. When some of the ordinary matter fields transform under the anomalous U(1), we find a hybrid scenario in which the U(1) and the gauge interactions mediate the breaking of supersymmetry. This leads to a hierarchy of soft masses between the charged and neutral fields and provides a solution to the $\\mu$-problem. Among these models, we present a scenario in which the Higgs arises as a pseudo-Goldstone boson. This scenario naturally allows for values of the $\\mu$-term and the scalar soft masses larger than the weak scale.

  3. A search for a new gauge boson A'

    In the Standard Model, gauge bosons mediate the strong, weak, and electromagnetic forces. New forces could have escaped detection only if their mediators are either heavier than order(TeV) or weakly coupled to charged matter. New vector bosons with small coupling {alpha}' arise naturally from a small kinetic mixing with the photon and have received considerable attention as an explanation of various dark matter related anomalies. Such particles can be produced in electron-nucleus fixed-target scattering and then decay to e+e-+ pairs. New light vector bosons and their associated forces are a common feature of Standard Model extensions, but existing constraints are remarkably sparse. The APEX experiment will search for a new vector boson A' with coupling α'/αfs > 6 × 10-8 to electrons in the mass range 65MeV < mass A' < 550MeV. The experiment will study e+e- production off an electron beam incident on a high-Z target in Hall A at Jefferson Lab. The e- and e+ will be detected in the High Resolution Spectrometers (HRSs). The invariant mass spectrum of the e+e- pairs will be scanned for a narrow resonance corresponding to the mass of the A'. A test run for the APEX experiment was held in the summer of 2010. Using the test run data, an A' search was performed in the mass range 175-250 MeV. The search found no evidence for an A' → e+e-reaction, and set an upper limit of {alpha}'/{alpha}{sub fs} ~ 10-6.

    Searches for neutral Higgs bosons produced at LEP in association with Z bosons, in pairs and in the Yukawa process are presented in this paper. Higgs boson decays into b quarks, tau leptons, or other Higgs bosons are considered, giving rise to four-b, four-b+jets, six-b and four-tau final states, as well as mixed modes with b quarks and tau leptons. The whole mass domain kinematically accessible at LEP in these topologies is searched. The analysed data set covers both the LEP1 and LEP2 energy ranges and exploits most of the luminosity recorded by the DELPHI experiment. No convincing evidence for a signal is found, and results are presented in the form of mass-dependent upper bounds on coupling factors (in units of model-independent reference cross-sections) for all processes, allowing interpretation of the data in a large class of models.

    This paper describes flavour independent searches for hadronically decaying neutral Higgs bosons in the data collected by the DELPHI experiment at LEP, at centre-of-mass energies between 189 and 209 GeV. The collected data-set corresponds to an integrated luminosity of around 610 pb^{-1}. The e+e- -> hA and e+e- -> hZ processes are considered, with direct Higgs boson decays into hadrons. No evidence for Higgs boson production is found, and cross-section limits are set as a function of the Higgs boson masses. No explicit assumptions are made on the underlying physics beyond the Standard Model, allowing interpretation of the data in a large class of models.

    Grand unification theories are a possible extension of the standard model. These theories imply the existence of an extra gauge boson: Z'. The study of the parameters of this boson in its electronic decays, especially its width, needs a good uniformity and a good resolution of the electromagnetic calorimeter. The first part of this thesis is dedicated to the study of the response of the barrel of the electromagnetic calorimeter to a 245 GeV electron beam. The major part of this work was the measurement of the uniformity. To perform this analysis the search of problematic channel has been made and corrections have been developed to take into account effect from the detector and to use all the recorded events. In the second part, I have studied the potential of Atlas in the study of the Z' decaying into lepton pairs (mainly in electron pairs). A study of the kinematic and of the background has been performed. This analysis deals with the possibility to distinguish different grand unification models, and with the possibility to discover the Z' boson, for masses from 1 TeV up to 4 TeV. (author)

    The LIPSS search for a light neutral scalar boson coupling to optical photons is reported. The search covers a region of parameter space of approximately 1.0 meV and coupling strength greater than 10^-6 GeV^-1. The LIPSS results show no evidence for scalar coupling in this region of parameter space.

    In an extension of the Standard Model(SM) based on the ideas of Lee and Wick, Grinstein, O'Connell and Wise have found an interesting way to remove the usual quadratically divergent contributions to the Higgs mass induced by radiative corrections. Phenomenologically, the model predicts the existence of Terascale, negative-norm copies of the usual SM fields with rather unique properties: ghost-like propagators and negative decay widths, but with otherwise SM-like couplings. The model is both unitary and causal on macroscopic scales. In this paper we examine whether or not such states with these unusual properties can be uniquely identified as such at the LHC. We find that in the extended strong and electroweak gauge boson sector of the model, which is the simplest one to analyze, such an identification can be rather difficult. Observation of heavy gluon-like resonances in the dijet channel offers the best hope for this identification.

  9. Composite models of quarks, leptons and gauge bosons

    The current topics on composite models, in which quarks and leptons are made of subquarks, that is, more fundamental particles, are discussed. Among various topics, the discussion is concentrated on the flavor mixing, the minimal composite model of quarks and leptons is introduced as a standard of reference for discussions in this work. It consists of an isodoublet of subquarks and a color quartet of scalar subquarks. The quarks and leptons of the first generation can be taken as the composite states of these subquarks. The gauge bosons as well as the Higgs scalars can also be taken as the composite states of subquark-antisubquark pairs. This minimal composite model may reproduce QFD, QCD and some results of the grand unifified SU(5) gauge theory of Georgi and Glashow. Nucleon decay, the mass spectra of quarks and leptons, mass scale for the sub-structure, and quarks and leptons as Nambu-Goldstone fermions are briefly discussed on the basis of the composite model. The mixing matrix of quarks can be defined by the matrix element of the subquark current between the m-th up-like quark and the n-th down-like quark. The mixing matrix elements may vary as the functions of momentum transfer between quarks. The results of calculation showed that the quark mixing matrix elements drastically changed when the momentum transfer between quarks grew up to an order of the size inverse of quarks. (Kato, T.)

  10. The $\\varrho$ parameter and the Screening Phenomenon for extra W and Z gauge bosons

    We generalize a previous construction of a fermiophobic model to the case of more than one extra $W$ and $Z$ gauge bosons. We focus in particular on the existence of screening configurations and their implication on the gauge boson mass spectrum. One of these configurations allows for the existence of a set of relatively light new gauge bosons, without violation of the quite restrictive bounds coming from the $\\rho_{\\rm NC}$ parameter. The links with Bess and degenerate Bess models are also discussed.

  11. Neutral currents without gauge theory prejudices

    The measurement of weak neutral current processes allows a determination of the space-time structure and the isospin structure of these currents. The inclusive production data and the elastic neutrino electron scattering rules out a pure V or A structure of the current. A pure isoscalar current is in disagreement with the experimental data for the one pion production off neutrinos. Further aspects of the neutral current can be determined in neutrino-nucleus-scattering experiments. (BJ) [de

    The triple gauge-boson couplings, Awp, Aw and Abp, have been measured using 34 semileptonically and 54 hadronically decaying WW candidate events. The events were selected in the data recorded during 1996 with the ALEPH detector at 172 GeV, corresponding to an integrated luminosity of 10.65 pb^-1. The triple gauge-boson couplings have been measured using optimal observables constructed from kinematic information of WW events. The results are in agreement with the Standard Model expectation.

    In this work we show several aspects of collider physics. In the first part we begin with an introduction for the parton model which is necessary for studying hadronic collider. Then we present our study of top quark pair production with an extra gluon at Tevatron. In the second part we present our contribution to the search for new physics using effective Lagrangian to probe gauge boson couplings. Particularly, we present our study of anomalous gauge boson couplings in the reaction {gamma} {gamma} ->V V V, which will occur at NLC operating in the {gamma} {gamma} mode. (author)

    Anomalous quartic couplings between the electroweak gauge bosons may contribute to the vv gamma gamma and qq gamma gamma final states produced in e+e- collisions. This analysis uses the LEP2 OPAL data sample at centre-of-mass energies up to 209 GeV. Event selections identify vv gamma gamma and qq gamma gamma events in which the two photons are reconstructed within the detector acceptance. The cross-section for the process e+e- -> qq gamma gamma is measured. Averaging over all energies, the ratio of the observed e+e- -> qq gamma gamma cross-section to the Standard Model expectation is R(data/SM) = 0.92 +- 0.07 +- 0.04 where the errors represent the statistical and systematic uncertainties respectively. The vv gamma gamma and qq gamma gamma data are used to constrain possible anomalous W+W- gamma gamma and ZZ gamma gamma couplings. Combining with previous OPAL results from the W+W- gamma final state, the 95% confidence level limits on the anomalous coupling parameters aoz, acz, aow and acw are found to be: -0.0...

  16. Heavy Flavor Gauge Boson search at the LHC

    CERN Document Server

    AUTHOR|(INSPIRE)INSPIRE-00214690

    Despite its many successes, the Standard Model (SM) [1] of particle physics is believed to be an effective field theory valid only for energies up to the TeV scale. Due to its uniquely large mass, the top quark is of particular interest for the electroweak symmetry breaking mechanism and could potentially be related to new physics phenomena. Several proposed extensions to the SM predict the existence of heavy particles that decay primarily to top quark pairs. This thesis contains two parts: a theoretical motivation study. This work included Monte Carlo modelling of flavor gauge boson models. The experimental search is made in the top anti-top decay channel collected with the ATLAS experiment during Run-1 and early Run-2 where one W from a top decays leptonically (to an electron or muon plus neutrino) and the W from the second top decays hadronically. This leads to a signature with one high-transverse- momentum lepton, large missing transverse momentum (from the escaping neutrino) and hadronic jets.

    This article describes the analysis methods and the results of the searches for the MSSM neutral Higgs bosons at LEP. The analysis strategies used on the L3 experiment are described. The analyses are carried out on 216.6 pb/sup -1/ data collected by the L3 detector at centre-of-mass energies from 200 GeV to 209 GeV. No signal is observed. Combining the analyses from the LEP experiments, preliminary lower mass limits are given as a function of the tan beta parameter. (8 refs).

    The CP-conserving triple-gauge-boson couplings, g1Z, kappa_gamma, lambda_gamma, g5Z, kappa_Z and lambda_Z are measured using hadronic and semi-leptonic W-pair events selected in 629 pb-1 of data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 209 GeV. The results are combined with previous L3 measurements based on data collected at lower centre-of-mass energies and with the results from single-W production and from events with a single-photon and missing energy. Imposing the constraints kappa_Z = g1Z - tan^2(theta_W) (kappa_gamma-1) and lambda_Z = lambda_gamma, we obtain for the C and P conserving couplings the results: g1Z = 0.966 +/- 0.033 (stat.) +/- 0.015 (syst.) kappa_gamma = 1.013 +/-0.066 (stat.) +/- 0.026 (syst.) lambda_gamma = -0.021 +/- 0.035 (stat.) +/-0.017 (syst.). Results from the analysis of fully leptonic W-pair decays are also given. All results are in agreement with the Standard Model expectations and confirm the existence of self-couplings among electroweak ...

    2016-01-01

    The ATLAS collaboration has carried out a set of measurements at center-of-mass energies of 8 TeV and 13 TeV which provide stringent tests of the electroweak sector of the Standard Model, specifically on di- and multibosonproduction cross sections. Such measurements include inclusive and differential cross sections for the production of two heavy gauge bosons (WW, WZ, ZZ) in the leptonic or semileptonic channels, the search for the production of three W bosons, the production of a Z boson in association with one or two photons, a Z or W boson in the vector-boson fusion channel, the observation of vector-boson scattering in the WW channel and the search for WZ production via vector-boson scattering. These measurements are compared to (N)NLO predictions of the Standard Model and provide model-independent constraints on new physics, by setting limits on anomalous triple or quartic gauge-boson couplings. We also present a measurement of the exclusive gamma+gamma >WW production cross-section and a search for exclu...

    The triple gauge-boson couplings, αWΦ, αW and αBΦ, have been measured using 34 semileptonically and 54 hadronically decaying W+W- candidate events. The events were selected in the data recorded during 1996 with the ALEPH detector at 172 GeV, corresponding to an integrated luminosity of 10.65 pb-1. The triple gauge-boson couplings have been measured using optimal observables constructed from kinematic information of W+W- events. The results are in agreement with the Standard Model expectation.

    1997-01-01

    In this work we show several aspects of collider physics. In the first part we begin with an introduction for the parton model which is necessary for studying hadronic collider. Then we present our study of top quark pair production with an extra gluon at Tevatron. In the second part we present our contribution to the search for new physics using effective Lagrangian to probe gauge boson couplings. Particularly, we present our study of anomalous gauge boson couplings in the reaction γ γ ->V V V, which will occur at NLC operating in the γ γ mode. (author)

  2. 125 GeV Higgs boson mass from 5D gauge-Higgs unification

    Science.gov (United States)

    Carson, Jason; Okada, Nobuchika

    2018-03-01

    In the context of a simple gauge-Higgs unification (GHU) scenario based on the gauge group SU(3)×U(1)^' in a 5D flat space-time, we investigate the possibility of reproducing the observed Higgs boson mass of around 125 GeV. We introduce bulk fermion multiplets with a bulk mass and a (half-)periodic boundary condition. In our analysis, we adopt a low-energy effective theoretical approach of the GHU scenario, where the running Higgs quartic coupling is required to vanish at the compactification scale. Under this "gauge-Higgs condition," we investigate the renormalization group evolution of the Higgs quartic coupling and find a relation between the bulk mass and the compactification scale so as to reproduce the 125 GeV Higgs boson mass. Through quantum corrections at the one-loop level, the bulk fermions contribute to the Higgs boson production and decay processes and deviate the Higgs boson signal strengths at the Large Hadron Collider experiments from the Standard Model (SM) predictions. Employing the current experimental data that show that the Higgs boson signal strengths for a variety of Higgs decay modes are consistent with the SM predictions, we obtain lower mass bounds on the lightest mode of the bulk fermions to be around 1 TeV.

  4. Measurements of Multi-boson production, Trilinear and Quartic Gauge Couplings with the ATLAS detector

    International Nuclear Information System (INIS)

    Becker, Maurice

    2016-01-01

    The ATLAS collaboration has carried a set of measurements that provide stringent tests of the electroweak sector of Standard Model, specifically on di- and multiboson production cross sections and on triple and quartic gauge-boson couplings. Such measurements include cross sections for WV (V=W or Z) production in the leptonic or semileptonic channels, the production of a W or Z boson in association with photons, a Z boson in the vector-boson fusion channel and two same-charge W bosons in the vectorboson scattering channel. These measurements are compared to (N)NLO predictions of the Standard Model and provide model-independent constraints on new physics, by setting limits on anomalous gauge-boson couplings. An analysis of the inclusive four-lepton lineshape has been carried out in the mass range from 80 to 1000 GeV, where several distinct physics processes give rise to the production of 4-lepton final state, namely the single Z resonant processes, the Higgs production at 125 GeV, as well as continuum ZZ production processes with qq-bar and gg initial states

    2017-01-01

    In this talk, we will give an overview of several recent measurements, performed at the ATLAS detector, which test the electroweak sector of the Standard Model to highest precision and allow for precision tests of perturbative QCD predictions. Cross section measurements of multi boson final states test the gauge structure of the Standard Model. Differential cross-section measurements of single vector bosons in the final state, also in association with jets, have been performed at all available center of mass energies and provide important information for advanced theoretical predictions as well as the parton density functions of the boson. These measurements build the basis for the first precision measurement of the W boson mass at the LHC.

    2018-01-01

    Measurements of the Drell-Yan production of W and Z/gamma* bosons at the LHC provide a benchmark of our understanding of perturbative QCD and probe the proton structure in a unique way. The ATLAS and CMS collaborations have performed several high precision measurements at different center-of-mass energies, ranging from single to triple differential cross sections. These measurements are the key in improving physics modelling uncertainties of electroweak precision measurements at the LHC. Moreover, perturbative QCD can be tested further in a multi-scale environment, when studying the production of jets in association with single and di-bosons final states. In this talk, we review the latest measurements, discuss the compatibility between the experiments and compare the results to the state-of-the-art QCD calculations and Monte Carlo simulations, as well their potential impact on improving our understanding PDFs.

  7. Probing electroweak gauge boson scattering with the ATLAS detector at the large hadron collider

    International Nuclear Information System (INIS)

    Anger, Philipp

    2014-01-01

    Electroweak gauge bosons as central components of the Standard Model of particle physics are well understood theoretically and have been studied with high precision at past and present collider experiments. The electroweak theory predicts the existence of a scattering process of these particles consisting of contributions from triple and quartic bosonic couplings as well as Higgs boson mediated interactions. These contributions are not separable in a gauge invariant way and are only unitarized in the case of a Higgs boson as it is described by the Standard Model. The process is tied to the electroweak symmetry breaking which introduces the longitudinal modes for the massive electroweak gauge bosons. A study of this interaction is also a direct verification of the local gauge symmetry as one of the fundamental axioms of the Standard Model. With the start of the Large Hadron Collider and after collecting proton-proton collision data with an integrated luminosity of 20.3 fb -1 at a center-of-mass energy of √(s)=8 TeV with the ATLAS detector, first-ever evidence for this process could be achieved in the context of this work. A study of leptonically decaying W ± W ± jj, same-electric-charge diboson production in association with two jets resulted in an observation of the electroweak W ± W ± jj production with same electric charge of the W bosons, inseparably comprising W ± W ± →W ± W ± electroweak gauge boson scattering contributions, with a significance of 3.6 standard deviations. The measured production cross section is in agreement with the Standard Model prediction. In the course of a study for leptonically decaying WZ productions, methods for background estimation, the extraction of systematic uncertainties and cross section measurements were developed. They were extended and applied to the WZjj final state whereof the purely electroweakly mediated contribution is intrinsically tied to the scattering of all Standard Model electroweak gauge bosons: W

    2001-01-01

    We analyze the potential of the Fermilab Tevatron and CERN Large Hadron Collider to study anomalous quartic vector--boson interactions (photon photon Z Z) and (photon photon W+ W-). Working in the framework of SU(2)_L X U(1)_Y chiral Lagrangians, we study the production of photons pairs accompanied by (e+ e-) and (e nu) to impose bounds on these new couplings, taking into account the unitarity constraints. We compare our findings with the indirect limits coming from precision electroweak measurements as well as with presently available direct searches at LEPII. We show that the Tevatron Run II can provide limits on these quartic limits which are of the same order of magnitude as the existing bounds from LEPII searches. LHC will be able to tighten considerably the direct constraints on these possible new interactions, matching the presently available indirect bounds.

  9. On the detectability of right-handed gauge bosons at hadron collider

    Masiero, A.

    1989-01-01

    The W R and Z R decays into a pair of left-handed vector bosons (the usual W and Z of the standard model) or into a single vector boson plus a scalar Higgs give rise to anomalous events where a high transverse-momentum lepton pair recoils against hadronic jets. It was analysed that the production of such anomalous events at proton-proton and proton-antiproton colliders. It was argued that these decay modes of W R and Z R may represent a crucial signature to identify an e + e - resonance as a right-handed gauge boson already at Tevatron. The results show that it is worthwhile undertaking a detailed analysis of the signal to background ratio to establish the detectability of W R and Z R via this mechanism. (author) 13 refs.; 2 tabs

    Neutral triple-gauge-boson couplings ZZZ, ZZgam and Zgamgam have been studied with the DELPHI detector using data at energies between 183 and 208 GeV. Limits are derived on these couplings from an analysis of the reactions e+e- -> Zgam, using data from the final states gamma f fbar, with f = q or neutrino, from e+e- -> ZZ, using data from the four-fermion final states q qbar q qbar, q qbar mu+ mu-, q qbar e+ e-, q qbar nu nubar, mu+ mu- nu nubar and e+ e- nu nubar, and from e+e- -> Zgam*, in which the final state gamma is off mass-shell, using data from the four-fermion final states q qbar e+ e- and q qbar mu+ mu-. No evidence for the presence of such couplings is observed, in agreement with the predictions of the Standard Model.

    2002-01-01

    The potential for probing the Standard Model of elementary particle physics by measuring the interactions of W-bosons with Z0-bosons and photons (WW and WWZ triple gauge-boson couplings) using TeV-scale proton-proton collisions is described in the context of the ATLAS detector at the 14 TeV Large Hadron Collider (LHC). The ATLAS detector and LHC are currently under construction at the European Organization for Nuclear Research (CERN), with the first data expected in 2006. New analysis techniques are presented in this thesis: (1) A new strategy for placing limits on the consistency of measured anomalous triple gauge-boson coupling parameters with the Standard Model is presented. The strategy removes the ambiguities of form factors, by reporting the limits as a function of a cutoff operating on the diboson system invariant mass. (2) The `optimal observables' analysis strategy is investigated in the context of hadron colliders, and found to be not competitive, as compared to other strategies. (3) Techniques for ...

    Lane, Rebecca Charlotte

    2015-01-01

    The Compact Muon Solenoid (CMS) detector is located at the CERN Large Hadron Collider. It is a general purpose detector designed to test predictions of the standard model (SM) and search for the Higgs boson, as well as to look for signatures of new physics beyond the SM. The analyses described in this thesis use proton-proton collision data recorded by CMS during 2011 and 2012. Searches for neutral Higgs bosons decaying into tau pairs are presented. The searches are performed separately for the SM Higgs boson or the neutral Higgs bosons of the minimal supersymmetric standard model (MSSM). The MSSM searches consist of two different analyses. The first is a direct search for any one of the MSSM neutral Higgs bosons in the mass range from 90 GeV to 1 TeV decaying directly into taus. The second searches for the signature from a heavy neutral Higgs boson of the MSSM decaying into two light MSSM Higgs bosons with SM-like properties (H $\\to$ hh) in the final state with two b-quarks and two taus. The SM and MSSM $\\ta...

  13. Determination of the masses of electrical weak gauge bosons with L3

    Rosenbleck, Christian

    2006-01-01

    This thesis presents the measurement of the masses of the carriers of the weak force in the Standard Model of Particle Physics, the gauge bosons W and Z. The masses are determined using the kinematics of the bosons' decay products. The data were collected by the L3 experiment at the Large Electron Positron Collider (LEP) at centre-of-mass energies, sqrt(s), between 183 GeV and 209 GeV in the years 1997 to 2000. The mass of the Z-boson, mZ, is already known very precisely: The L3 collaboration determined it to be mZ = 91.1898 +- 0.0031 GeV from a scan of the Z resonance. Therefore the main aim of this analysis is not the determination of the numerical value of mZ; instead the analysis is used to cross-check the measurement of the W boson mass since the methods are similar. Alternatively, the analysis can be used to measure the mean centre-of-mass energy at the L3 interaction point. The Z-boson mass is determined to be mZ = 91.272 +- 0.046 GeV. If interpreted as measurement of the centre-of-mass energy, this va...

  14. A search for neutral Higgs bosons at high tan beta in multi-jet events from p anti-p collisions at √s = 1960-GeV

    2004-01-01

    The Higgs mechanism preserves the gauge symmetries of the Standard Model while giving masses to the W, Z bosons. Supersymmetry, which protects the Higgs boson mass scale from quantum corrections, predicts at least 5 Higgs bosons, none of which has been directly observed. This thesis presents a search for neutral Higgs bosons, produced in association with bottom quarks. The production rate is greatly enhanced at large values of the Supersymmetric parameter tan β. High-energy p$\\bar{p}$ collision data, collected from Run II of the Fermilab Tevatron using the D0 detector, are analyzed. In the absence of a signal, values of tan β > 80-120 are excluded at 95% Confidence Level (C.L.), depending on the (CP-odd) neutral Higgs boson mass (studied from 100 to 150 GeV/c2).

  15. Study of electroweak gauge boson scattering in the WZ channel with the ATLAS detector at the Large Hadron Collider

    Socher, Felix

    2016-07-15

    The Standard Model of particle physics is a very well tested gauge theory describing the strong, weak and electromagnetic interactions between elementary particles through the exchange of force carriers called gauge bosons. Its high predictive power stems from its ability to derive the properties of the interactions it describes from fundamental symmetries of nature. Yet, it is not a final theory as there are several phenomena it cannot explain. Furthermore, not all of its predictions have been studied with sufficient precision, e.g. the properties of the newly discovered Higgs boson. Therefore, further probing of the Standard Model is necessary and may result in finding possible indications for new physics. The non-abelian SU(2){sub L} x U(1){sub Y} symmetry group determines the properties of the electromagnetic and weak interactions giving rise to self-couplings between the electroweak gauge bosons, i.e. the massive W and Z boson, and the massless photon, via triple and quartic gauge couplings. Studies carried out over the past 20 years at various particle accelerator experiments have shed light on the structure of the triple gauge couplings but few results on quartic gauge couplings are available. The electroweak self-couplings are intertwined with the electroweak symmetry breaking and thus the Higgs boson through the scattering of massive electroweak gauge bosons. Both the W and Z boson couple to the Higgs boson and may interact with each other by exchanging it. Theory predictions yield physical results at high energies only if either both the self-couplings and Higgs boson properties are as described by the Standard Model or if they deviate from its predictions and contributions from new physics are present to render the calculations finite. This makes electroweak gauge boson scattering a powerful tool to probe the Standard Model and search for possible effects of new physics. The small cross section of massive electroweak gauge boson scattering necessitates

  16. Higgs as a pseudo-Goldstone boson, the mu problem and gauge-mediated supersymmetry breaking

    We study the interplay between the spontaneous breaking of a global symmetry of the Higgs sector and gauge-mediated supersymmetry breaking, in the framework of a supersymmetric model with global SU(3) symmetry. In addition to solving the supersymmetric flavor problem and alleviating the little hierarchy problem, this scenario automatically triggers the breaking of the global symmetry and provides an elegant solution to the μ/Bμ problem of gauge mediation. We study in detail the processes of global symmetry and electroweak symmetry breaking, including the contributions of the top/stop and gauge-Higgs sectors to the one-loop effective potential of the pseudo-Goldstone Higgs boson. While the joint effect of supersymmetry and of the global symmetry allows in principle the electroweak symmetry to be broken with little fine-tuning, the simplest version of the model fails to bring the Higgs mass above the LEP bound due to a suppressed tree-level quartic coupling. To cure this problem, we consider the possibility of additional SU(3)-breaking contributions to the Higgs potential, which results in a moderate fine-tuning. The model predicts a rather low messenger scale, a small tan β value, a light Higgs boson with Standard Model-like properties, and heavy higgsinos. (orig.)

  17. Possible origin of a natural conservation of flavor in an interaction with neutral Higgs bosons

    In technicolor models the masses of the neutral pseudo-Goldstone bosons which interact with quarks and leptons without flavor conservation automatically acquire an order of magnitude Mapprox.(m/sub q/#betta#/sub TC/)/sup 1/2/approx.0.2--1 TeV through the Yukawa interaction. As a result, an effective Lagrangian which conserves only light Higgs bosons satisfies the condition of natural flavor conservation

    The transverse momentum spectra of weak gauge bosons and their ratios probe the underlying dynamics and are crucial in testing our understanding of the Standard Model. They are an essential ingredient in precision measurements, such as the $\\mathrm{W}$-boson mass extraction. To fully exploit the potential of the LHC data, we compute the second-order (NNLO) QCD corrections to the inclusive-$p_\\mathrm{T}^\\mathrm{W}$ spectrum as well as to the ratios of spectra for $\\mathrm{W}^-/\\mathrm{W}^+$ and $\\mathrm{Z}/\\mathrm{W}$. We find that the inclusion of NNLO QCD corrections considerably improves the theoretical description of the experimental CMS data and results in a substantial reduction of the residual scale uncertainties.

    Triple gauge boson couplings are measured from W-pair and single photon events recorded by the OPAL detector at LEP at center-of-mass energies between 183 - 209 GeV with a total integrated luminosity of 680 inverse picobarns. Only CP-conserving couplings are considered and SU(2)xU(1) relations between the WWZ and the WWgamma couolings are used, resulting in four independent couplings. Each coupling is determined in a separate fit, assuming the other couplings to take their Standard Model values. Fits are also done allowing some of the couplings to vary simultaneously. The results are compared with the Standard Model predictions.

  20. A Search for Neutral Supersymmetric Higgs Bosons at DØ

    Energy Technology Data Exchange (ETDEWEB)

    Osman, Nicolas Ahmed [Imperial College, London (United Kingdom)

    2010-09-01

    A search for Higgs bosons in multijet data from the DØ detector is reported in this thesis. The Higgs boson is the only remaining undiscovered particle in the Standard Model of particle physics, and plays an integral role in this model. It is known that this model is not a complete description of fundamental physics (it does not describe gravity, for example), and so searches for physics beyond the Standard Model are an important part of particle physics. One extension of the Standard Model, the Minimal Supersymmetric Standard Model (MSSM), predicts the existence of five Higgs bosons, two of which can show an enhanced coupling to bottom quarks. For this reason, a search in the bbb (multijet) channel is a sensitive test of Higgs boson physics. The analysis described in this thesis was conducted over 6.6 fb-1 of data. At the time of writing, the best limits on tan β (a key parameter of the MSSM) in the multijet channel were set by DØ. The new analysis described in this thesis included more data than the previous analysis in the channel, and made use of a new trigger and event-based analysis method. An improved Multivariate Analysis technique was used to separate signal and background events and produce a final discriminant for the limit setting process. These changes increased the expected sensitivity of this measurement by roughly 50% more than would be expected from the increase in the size of data sample alone.

    We have searched for heavy neutral gauge bosons (Z ' ) in bar pp collisions at √s=1.8 TeV. The data were obtained using the CDF detector during the 1992--1993 run corresponding to an integrated luminosity of 19.7±0.7 pb -1 . We present a 95% confidence level upper limit on the production cross section times the branching ratio of Z ' decaying into dielectrons as a function of Z ' mass. Assuming standard model coupling strengths, we exclude a Z ' with a mass less than 505 GeV/c 2 . We also present lower mass limits for Z ' bosons from E 6 models and the alternative left-right model

    All lowest-order amplitudes for e+e- --> 4f+gamma are calculated including five anomalous quartic gauge-boson couplings that are allowed by electromagnetic gauge invariance and the custodial SU(2)_c symmetry. Three of these anomalous couplings correspond to the operators L_0, L_c, and L_n that have been constrained by the LEP collaborations in WWgamma production. The anomalous couplings are incorporated in the Monte Carlo generator RACOONWW. Moreover, for the processes e+e- --> 4f+gamma RACOONWW is improved upon including leading universal electroweak corrections such as initial-state radiation. The discussion of numerical results illustrates the size of the leading corrections as well as the impact of the anomalous quartic couplings for LEP2 energies and at 500GeV.

    We examine the prospects of searching for dilepton gauge bosons in e - p colliders. Specifically we take a SU(3) C xSU(3) L xU(1) X model and calculate the cross section for the process, e - p→e + +D+anything, mediated by doubly-charged dilepton gauge bosons, where D is a new quark predicted by the model. At HERA, with center-of-mass energy √s=314 GeV and the integrated luminosity 100pb -1 , we can obtain the signature of dileptons with mass up to 340 GeV (650 GeV) if D has a mass lighter than 200 GeV (150 GeV). At LEPII-LHC, with center-of-mass energy √s=1790 GeV and the anticipated luminosity 6fb -1 yr -1 , we expect more than 280 events per year provided that both masses of dileptons and D-quarks are less than 1 TeV.

  5. Dark matter annihilations into two light fermions and one gauge boson. General analysis and antiproton constraints

    We study in this paper the scenario where the dark matter is constituted by Majo- rana particles which couple to a light Standard Model fermion and an extra scalar via a Yukawa coupling. In this scenario, the annihilation rate into the light fermions with the mediation of the scalar particle is strongly suppressed by the mass of the fermion. Nevertheless, the helicity suppression is lifted by the associated emission of a gauge boson, yielding annihilation rates which could be large enough to allow the indirect detection of the dark matter particles. We perform a general analysis of this scenario, calculating the annihilation cross section of the processes χχ → f anti fV when the dark matter particle is a SU(2) L singlet or doublet, f is a lepton or a quark, and V is a photon, a weak gauge boson or a gluon. We point out that the annihilation rate is particularly enhanced when the dark matter particle is degenerate in mass to the intermediate scalar particle, which is a scenario barely constrained by collider searches of exotic charged or colored particles. Lastly, we derive upper limits on the relevant cross sections from the non-observation of an excess in the cosmic antiproton-to-proton ratio measured by PAMELA. (orig.)

  7. Lμ-Lτ gauge-boson production from lepton flavor violating τ decays at Belle II

    Lμ-Lτ gauge boson (Z') with a mass in the MeV to GeV region can resolve not only the muon g -2 excess, but also the gap in the high-energy cosmic neutrino spectrum at IceCube. It was recently proposed that such a light gauge boson can be detected during the Belle II experiment with a luminosity of 50 ab-1 by the e+e-→γ +E process through the kinetic mixing with the photon, where the missing energy E is from the Z'→ν ¯ν decays. We study the phenomenological implications when a pair of singlet vectorlike leptons carrying different Lμ-Lτ charges are included, and a complex singlet scalar (ϕS) is introduced to accomplish the spontaneous U (1 )Lμ-Lτ symmetry breaking. It is found that the extension leads to several phenomena of interest, including (i) branching ratio (BR) for h →μ τ can be of the order of 10-3; (ii) ϕS-mediated muon g -2 can be of the order of 10 ×10-10; (iii) BR for τ →μ ϕS*→μ Z'Z' can be 10-8, and (iv) kinetic mixing between the Z' boson and photon is sensitive to the relative heavy lepton masses. The predicted BRs for τ →(3 μ +E ,5 μ ) through the leptonic Z' decays can reach a level of 10-9, in which the results fall within the sensitivity of the Belle II in the search for the rare tau decays.

    We have performed an experimental study reporting the measurements of e+e- pairs in nucleus - nucleus interactions, using 32 S (200 A GeV) beam from CERN and [ 12 C and 22 Ne (3.7 A GeV)] beams from Dubna. From the interactions of such beams with nuclear emulsion, 134 electron pairs have been observed. Challenging observations are found to be remarkably similar to 57 years old emulsion data, from Bristol, obtained by exposure to cosmic ray. The results show that, both data are consistent in a way that, they scaled well in a single curve which provided a unified description of mesonic decay. The results suggest that the pairs originate from light neutral bosons emitted during the collisions, The origin of such neutral bosons could be due to deexcitation of the produced fragments 4 He, 8 Be and 12 C resulting in the fragmentation of 32 S, 22 Ne and 12 C beams. The masses of the neutral bosons were estimated from conservation laws of kinematics and found to be equal to 1.55± 0.14 MeV/c 2 . The corresponding lifetimes are of order of 10-16 s. The results could solve the puzzles which were going on during the last 5 decades around the anomalous mean free path of particle produced during high energy particle collisions of secondary helium fragments as compared to those of primary 4 He at similar energy. This result demonstrates the possibility of neutral boson formation

    Several theories, like the Minimal Supersymmetric Standard Model, predict a high mass neutral Higgs boson with a significant decay rate into the bb, mu-mu or tau-tau final states. The search for a scalar resonance in fermion decay channels is presented, using about 36 fb-1 of p-p collisions at 13 TeV.

    The Standard Model of particle physics is a very well tested gauge theory describing the strong, weak and electromagnetic interactions between elementary particles through the exchange of force carriers called gauge bosons. Its high predictive power stems from its ability to derive the properties of the interactions it describes from fundamental symmetries of nature. Yet, it is not a final theory as there are several phenomena it cannot explain. Furthermore, not all of its predictions have been studied with sufficient precision, e.g. the properties of the newly discovered Higgs boson. Therefore, further probing of the Standard Model is necessary and may result in finding possible indications for new physics. The non-abelian SU(2)L×U(1)Y symmetry group determines the properties of the electromagnetic and weak interactions giving rise to self-couplings between the electroweak gauge bosons, i.e. the massive W and Z boson, and the massless photon, via triple and quartic gauge couplings.

    If the Higgs boson discovered at the Large Hadron Collider (LHC) is not exactly the one in the Standard Model, an alternative mechanism is needed to restore unitarity in the scattering amplitude of longitudinal gauge bosons, and new resonances may appear.

    We study the hadroproduction of a CP-even or CP-odd neutral Higgs boson in association with a Z boson in the minimal supersymmetric extension of the standard model (MSSM) We include the contributions from quark-antiquark annihilation at the tree level and those from gluon-gluon fusion, which proceeds via quark and squark loops, and list compact analytic results. We quantitatively analyze the hadronic cross sections at the CERN Large Hadron Collider assuming a favorable supergravity-inspired MSSM scenario. (orig.)

  16. Natural suppression of flavour-changing neutral currents in supersymmetric gauge theories

    1982-01-01

    Induced flavour-changing neutral currents (FCNC) in supersymmetric unified theories are investigated both in models with the standard SU(2)sub(L) x U(1) gauge symmetry and in models with an extra U tilde(1) gauge symmetry. Supersymmetric extension of the natural flavour conservation laws for neutral currents is obtained by adding a condition regarding the assumed type of supersymmetry breaking. This condition ensures no direct flavour-changing couplings of neutral gauge-Higgs fermions and at the same time is necessary and sufficient for the natural suppression of the induced FCNC. It is found that in the class of models satisfying the new condition the contribution of the scalar partners of quarks to the induced strangeness-changing neutral current is comparable to that of the quarks in Ksub(L)→μanti μ, while it is negligibly small in Ksub(L)-Ksub(S) mass difference.

    We compute the full O({alpha}{sub s}) supersymmetric QCD corrections for neutralino-stop co-annihilation into electroweak gauge and Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM). We show that these annihilation channels are phenomenologically relevant within the so-called phenomenological MSSM, in particular in the light of the observation of a Higgs-like particle with a mass of about 126 GeV at the LHC. We present in detail our calculation, including the renormalization scheme, the infrared treatment, and the kinematical subtleties to be addressed. Numerical results for the co-annihilation cross sections and the predicted neutralino relic density are presented. We demonstrate that the impact of including the corrections on the cosmologically preferred region of parameter space is larger than the current experimental uncertainty from WMAP data.

  18. α-quantized Einstein masses for leptons, quarks, hadrons, gauge bosons, and Higgs constants

    The Einstein particle mass ɛi is defined by the equation ɛi = Ei / c^2. The basic particle ground states have unique additive Einstein masses (energies), and they interleave in α-quantized (α-1 = 137) energy plots to form distinctive excitation patterns. The ɛu,d,s,c,b,t Einstein masses are constituent-quark masses. Particle generation proceeds via ``α-boosted'' boson, fermion, and gauge-boson ``unit masses,'' which are ``bundled'' together to form particles and quarks. The Einstein mass equations extend throughout the entire range of particle masses. Lederman and HillootnotetextL. M. Lederman and C. T. Hill, Symmetry (Prometheus Books, Amherst, 2004), p. 282. note that the scalar Higgs and Fermi fields are at the 175 GeV energy scale of the top quark t, and they suggest the Higgs coupling constant equation ge=me/mt = 0.0000029, which matches the Einstein mass expression ge=α^2/18.

    A search for the neutral Higgs bosons h[sup O] and A[sup O], predicted by the Minimal Supersymmetric Extension of the Standard Model (MSSM), has been performed by the OPAL Collaboration at LEP. The analysis was based on approximately 75 pb[sup -1] of data taken at centre-of-mass energies in the vicinity of the Z[sup O] resonance. No Higgs boson signals have been detected. Using, in addition, an upper limit on the contribution of non-Standard Model processes to the Z[sup O] boson width, almost the entire MSSM parameter space that can be reached at present LEP energies has been excluded. In particular, at the 95% confidence level, our results imply that m[sub h[sup o

    Since a neural network (NN) approach has been shown to be applicable to the problem of Higgs boson detection at LHC [I. Iashvili, A. Kharchilava, CMS TN-1996/100; M. Mjahed, Nucl. Phys. B 140 (2005) 799], we study the use of NNs in the problem of tagging b jets in pp->bb-bar H SUSY , H SUSY ->ττ in the Compact Muons Solenoid experiment [F. Hakl, et al., Nucl. Instr. and Meth. A 502 (2003) 489; S. Lehti, CMS NOTE-2001/019; G. Segneri, F. Palla, CMS NOTE-2002/046]. B tagging is an important tool for separating the Higgs events with associated b jets from the Drell-Yan background Z,γ * ->ττ, for which the associated jets are mostly light quark and gluon jets. We teach multi-layer perceptrons (MLPs) available in the object oriented implementation of data analysis framework ROOT [ROOT-An Object Oriented Data Analysis Framework, in: Proceedings of the AIHENP'96 Workshop, Lausanne, September 1996, Nucl. Instr. and Meth. A 389 (1997) 81]. The following learning methods are evaluated: steepest descent algorithm (BFGS) Broyden-Fletcher-Goldfarb-Shanno algorithm, and variants of conjugate gradients. The ROOT code generation feature of standalone C++ classifiers is utilized. We compare the b tagging performance of MLPs with another ROOT based feed forward NN tool NeuNet [J.P. Ernenwein, NeuNet software for ROOT], which uses a common back-propagation learning method. In addition, we demonstrate the use of the self-organizing map program package (SOM P AK) and the learning vector quantization program package (LVQ P AK) [T. Kohonen, et al., SOM P AK: the self-organizing map program package, Technical Report A31; T.

The discovery and exclusion sensitivity in the (m$_A$, tan$\\beta$) plane in different luminosity scenarios is discussed for three processes: h/A/H decaying into $\\tau\\tau$ or into $\\mu\\mu$ pairs or in supersymmetric particles (heavy neutralino/chargino pairs).

    1996-01-01

    With μ→eγ decay forbidden by multiplicative lepton number conservation, we study muonium-antimuonium transitions induced by neutral scalar bosons. Pseudoscalars do not induce conversion for triplet muonium, while, for singlet muonium, pseudoscalar and scalar contributions add constructively. This is in contrast with the usual case of doubly charged scalar exchange, where the conversion rate is the same for both singlet and triplet muonium. Complementary to muonium conversion studies, high energy μ + e - →μ - e + and e - e - →μ - μ - collisions could reveal spectacular resonance peaks for the cases of neutral and doubly charged scalars, respectively. copyright 1996 The American Physical Society

    It is shown that in four-dimensional abelian (V-A) theories, the ground state of cold neutral fermionic matter is an anomalous state containing domains of abnormal phase surrounded by the normal vacuum. Inside these domains, there exists a gauge field condensate which makes real fermions disappear both inside and outside the domains. In non-abelian theories, the abnormal matter is unstable in its turn, and the system rolls back down into the normal state with a small number of fermions above the topologically non-trivial vacuum. Thus, in several non-abelian gauge theories, the fermion number density of cold neutral matter cannot exceed some critical value. (orig.)

    Measurements are presented of the polarisation of W+W- boson pairs produced in e+e- collisions, and of CP-violating WWZ and WWGamma trilinear gauge couplings. The data were recorded by the OPAL experiment at LEP during 1998, where a total integrated luminosity of 183 pb^-1 was obtained at a centre-of-mass energy of 189 GeV. The measurements are performed through a spin density matrix analysis of the W boson decay products. The fraction of W bosons produced with longitudinal polarisation was found to be sigma_L/sigma_total = (21.0 +- 3.3 +- 1.6)% where the first error is statistical and the second systematic. The joint W boson pair production fractions were found to be sigma_TT/sigma_total = (78.1 +- 9.0 +- 3.2) %, sigma_LL/sigma_total = (20.1 +- 7.2 +- 1.8) % and sigma_TL/sigma_total = (1.8 +- 14.7 +- 3.8) %. In the CP-violating trilinear gauge coupling sector we find kappa_z = -0.20 +0.10 -0.07, g^z_4 = -0.02 +0.32 -0.33 and lambda_z = -0.18 +0.24 -0.16, where errors include both statistical and systematic u...

  6. Search for Neutral MSSM Higgs bosons decaying to tau pairs in the ATLAS experiment

    CERN Multimedia

    Scutti, F

    2013-01-01

    The Minimal Supersymmetric Standard Model (MSSM) is a supersymmetric extension of the Standard Model of particle physics, predicting the existence of five Higgs bosons, two charged (H±) and three neutral (h, H, A). At tree level their properties are determined by two independent parameters: the mass of the CP-odd Higgs boson mA, and the ratio between the vacuum expectation values of the two Higgs doublets predicted tan(beta). In Supersymmetric models, the Higgs boson couplings to down-type fermions like b-quarks or tau leptons is significantly enhanced over a large region of the parameter space. Decays to tau lepton pairs occur 10% of the times and provide a cleaner environment for the search than decays to b-quarks. The tau lepton can decay into either a muon or an electron, plus neutrinos, or in hadrons plus neutrinos. In this poster, the search for the heavy neutral MSSM Higgses (h, H, A) is presented, where the final state is a pair of hadronically decaying tau leptons. This channel provides good sensit...

  7. On W∞ algebras, gauge equivalence of K P hierarchies, two-bosons realizations and their KdV reductions

    1994-01-01

    The gauge equivalence between basic KP hierarchies is discussed. The first two Hamiltonian structures for KP hierarchies leading to the linear and non-linear W ∞ algebras are derived. The realization of the corresponding generators in terms of two boson currents is presented and it is shown to be related to many integrable models which are bi-Hamiltonian. We can also realize those generators by adding extra currents, coupled in a particular way allowing for instance a description of multi-layered Benney equations or multi- component non-linear Schroedinger equation. In this case we can have a second Hamiltonian bracket structure which violates Jacobi identity. We consider the reduction to one-boson systems leading to KdV and mKdV hierarchies. A Miura transformation relating these two hierarchies is obtained by restricting gauge transformation between corresponding two-boson hierarchies. Connection to Drinfeld-Sokolov approach is also discussed in the SL (2, IR) gauge theory. (author)

    The triple gauge-boson couplings involving the W are determined using data samples collected with the ALEPH detector at mean centre-of-mass energies of 183 GeV and 189 GeV, corresponding to integrated luminosities of 57 pb^-1 and 174 pb^-1, respectively. The couplings, g^Z_1, Kappa_gamma and lambda_gamma, are measured using W-pair events, single-W production and single-gamma production. Each coupling is measured individually with the other two coupling fixed at their Standard Model value. Including ALEPH results from lower energies, the 95% confidence level intervals for the deviation to the Standard Model are -0.087 < Dg^Z_1 < 0.141 -0.200 < DKappa_gamma < 0.258 -0.062 < Lambda_gamma < 0.147. Fits are also presented where two or all three couplings are allowed to vary. In addition, W-pair events are used to set limits on the C- or P-violating couplings g^V_4, g^V_5, Kappa~_V, and Lambda~_V, where V denotes either gamma or Z. No deviations from the Standard Model expectations are observed.

    In this work we present a broad formalism for a study of the models of black holes, boson stars, boson shells and wormholes. The studies of boson stars and boson shells in a theory involving Scalar field, U(1) gauge field and a shelf interacting scalar potential coupled to gravity in the presence of a cosmological constant Λ are presented in details.

    We study the W and Z pair production from two-photon exchange in proton-proton collisions at the LHC in order to evaluate the contributions of anomalous photon-gauge boson couplings, that simulates new particles and couplings predicted in many Standard Model (SM) extensions. The experimental results of W{sup +} W{sup −} exclusive production (pp → pW{sup +}W{sup −} p) at 7 TeV from the CMS collaboration [1] updates the experimental limits on anomalous couplings obtained at the Large Electron-Positron Collider (LEP). This motivates our present analysis hopefully anticipating the expected results using the Precision Proton Spectrometer (PPS) to be installed as part of CMS. In this work, we consider the W{sup +}W{sup −} exclusive production to present the p{sub T} distribution of the lepton pair corresponding to the SM signal with p{sub T} (e, μ) > 10 GeV. Next, we consider the photon-gauge boson anomalous couplings by calculating, from the FPMC and MadGraph event generators, the process γγ → W{sup +}W{sup −} from a model with gauge boson quartic couplings, by considering a 1 TeV scale for new physical effects. We present our results for an integrated luminosity of 5 fb{sup −1} at center-of-mass energy of 7 TeV and for an integrated luminosity of 100 fb{sup −1} at 13 TeV. We present our preliminary results for Z pair exclusive production from two-photon exchange with anomalous couplings, where the ZZγγ quartic coupling is absent in the SM. We calculate the total cross section for the exclusive process and present the four lepton invariant mass distribution. Finally we present an outlook for the present analysis.

  13. QCD corrections to decay distributions of neutral Higgs bosons with (in)definite CP parity

    We compute the order α s QCD corrections to the density matrix for the decay of a neutral Higgs boson var-phi with (in)definite CP parity into a quark-antiquark pair and the QED corrections for the decay into a pair of charged leptons. We classify and calculate single spin asymmetries and spin-spin correlations which are generated by the scalar and pseudoscalar Yukawa couplings. These spin effects can be traced in var-phi →τ - τ + and, for heavy Higgs bosons, in var-phi →t bar t. We also calculate resulting correlations among the final states and estimate, for the respective decay modes, the number of events needed to measure the Yukawa couplings with these correlations at the 3σ level. copyright 1997 The American Physical Society

  14. Search for the neutral MSSM Higgs bosons in the ditau decay channels at CDF Run II

    This thesis presents the results on a search for the neutral MSSM Higgs bosons decaying to tau pairs, with least one of these taus decays leptonically. The search was performed with a sample of 1.8 fb-1 of proton-antiproton collisions at √s = 1.96 TeV provided by the Tevatron and collected by CDF Run II. No significant excess over the Standard Model prediction was found and a 95% confidence level exclusion limit have been set on the cross section times branching ratio as a function of the Higgs boson mass. This limit has been translated into the MSSM Higgs sector parameter plane, tanβ vs. MA, for the four different benchmark scenarios.

    A search for neutral Higgs bosons decaying to tau pairs at a center-of-mass energy of 7 TeV is performed using a dataset corresponding to an integrated luminosity of 4.6 inverse femtobarns recorded by the CMS experiment at the LHC. The search is sensitive to both the standard model Higgs boson and to the neutral Higgs bosons predicted by the minimal supersymmetric extension of the standard model (MSSM). No excess of events is observed in the tau-pair invariant-mass spectrum. For a standard model Higgs boson in the mass range of 110-145 GeV upper limits at 95% confidence level (CL) on the production cross section are determined. We exclude a Higgs boson with m(H)=115 GeV with a production cross section 3.2 times of that predicted by the standard model. In the MSSM, upper limits on the neutral Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, m(A), sets stringent new bounds in the parameter space, excluding at 95% CL values of tan(bet...

  16. A compact fast ionization gauge for in situ measurement of high-density neutral flow dynamics

    Weber, T. E.; Intrator, T. P.

    2014-04-01

    A compact ionization gauge has been developed to carry out in situ measurements of high density (1020-1022 m-3) neutral gas flow dynamics with high temporal and spatial resolution. Key design aspects are discussed including gauge sensitivity and time response scaling with decreased probe dimensions, high-pressure operation, improved driver circuit bandwidth, and techniques for constructing a miniaturized probe head. Gas adsorption was discovered to significantly alter emission current and gauge sensitivity over timescales of several seconds. This effect must be taken into consideration when making time-resolved, high-density measurements. Over short timescales gauge response was predicted by scaling the sensitivity of a nominal Bayard-Alpert gauge to account for variations in probe dimensions and species-dependent ionization cross-section. Time-resolved neutral density profiles have been acquired in the Magnetized Shock Experiment at Los Alamos National Laboratory, providing data on the initial conditions of the ionization, plasmoid formation, and translation processes. It is shown that the desired density profiles can be achieved using a dynamic gas fill and that density can be scaled independently of the spatial profile.

  17. Performances of the electromagnetic calorimeter and search for new gauge bosons in the di-electron channel at the LHC

    The Standard Model of particle physics has known a tremendous rise during the twentieth century. Built up, from the early thirties to the seventies, this theory describing elementary particles and their interactions (electromagnetic, weak, strong) has now been intensively tested by LEP and Tevatron colliders. Besides its success, some problems remain and have lead to new theories attempting to go beyond the standard model. Many of them are predicting the existence of a new gauge boson Z', which is supposed to be observed at the TeV scale. Data recorded by the LHC since autumn 2008 are a new opportunity to check the consistency of the Standard Model and to search for new physics evidence. The work that has been done by the ATLAS collaboration during the last four years has focused on understanding detector's behaviour and analysing the very first collected collisions. This thesis is reflecting these two aspects. Therefore, the first part of this thesis describes the characterisation of a pathology of ATLAS liquid argon calorimeter electronics and of coherent noise bursts that have both been observed since the beginning of ATLAS operation. The policy deployed to preserve data quality is also detailed. The second part is focusing on the search for new Z' gauge boson. In case this particle was to exist, its decay into an electron and a positron would lead to a new massive resonance in the dielectron invariant mass spectrum. Therefore electron reconstruction and identification performances are closely looked at, especially at high transverse momentum. Analysis made on the 4.9 fb -1 of collected data is reported. As no significant excess with respect to Standard Model predictions is observed, the dielectron invariant mass spectrum is interpreted to derive mass limits concerning the existence of new Z' gauge bosons appearing in grand unification theories (E6) and effective sequential standard model (SSM). These limits and those derived by the CMS collaboration are the

    We report on the first results of a sensitive search for scalar coupling of photons to a light neutral boson in the mass range of approximately 1.0 milli-electron volts and coupling strength greater than 10$^-6$ GeV$^-1$ using optical photons. This was a photon regeneration experiment using the "light shining through a wall" technique in which laser light was passed through a strong magnetic field upstream of an optical beam dump; regenerated laser light was then searched for downstream of a second magnetic field region optically shielded from the former. Our results show no evidence for scalar coupling in this region of parameter space.

  19. Pair production of Z and W polarization at LEP2 determined with ALEPH detector or Prolegomena to any future apparently complete study on gauge bosons

    2002-01-01

    The start of LEP2 at centre of mass energies higher then the W-pair production threshold, has made possible for the first time to test the least bounded sector of the Standard Model, the bosonic sector. This thesis consists in three strong measurements of the validity of the Standard Model using the whole LEP2 data set recorded by the ALEPH detector: - The measurement of the ZZ cross section through the five visible decay channels of the Z-pair. The poor statistic associated to pair production of Z is a process difficult to discriminate - The measurement of the anomalous neutral gauge couplings in tile ZZ final state. These couplings are forbidden in the Standard Model and their existence would be the signature of a New Physics. The information on the cross section as well as the angular distribution of the Z is used to extract them. - The measurement of the longitudinal and transverse polarised states of the W bosons through the W + W - production in the semi-leptonic channel. The spin density matrix method is used because it introduces a 'model independent' framework. No deviation is observed with respect to the Standard Model predictions. (author)

    This report summarizes the final results from the OPAL collaboration on searches for neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM). CP-conserving and for the first time at LEP CP-violating scenarios are studied. New scenarios are also included, which aim to set the stage for Higgs searches at future colliders. The results are based on the data collected with the OPAL detector at e+e- centre-of-mass energies up to 209 GeV. The data are consistent with the prediction of the Standard Model with no Higgs boson produced. Model-independent limits are derived for the cross-section of a number of events topologies motivated by prediction of the MSSM. Limits on Higgs boson masses and other MSSM parameters are obtained for a number of representative MSSM benchmark scenarios. For example, in the CP-conserving scenario mh-max where the MSSM parameters are adjusted to predict the largest range of values for mh at each tan beta, and for a top quark mass of 174.3 GeV, the domain 0.784.5 ...

    The ratio of neutral Higgs field vacuum expectation values, tan beta , is one of the most important parameters to determine in either the minimal supersymmetric standard model (MSSM) or a general type-II two-Higgs doublet model (2HDM). Assuming an energy and integrated luminosity of square root s=500 GeV and L=2000 fb/sup -1/ at a future linear collider (LC), we show that a very accurate determination of tan beta will be possible for low and high tan beta values by measuring the production rates of Higgs bosons and reconstructing Higgs boson decays. In particular, based on a TESLA simulation, and assuming no other light Higgs bosons and 100

    With the recent discovery of the SM (Standard Model) higgs boson of mass around 125 GeV by the CMS (Compact Muon Solenoid) and the ATLAS (A Toroidal LHC Apparatus) collaborations at the LHC (Large Hadron Collider) at CERN, there have been attempts to interpret this newly discovered resonance in the context of BSM (Beyond Standard Model) physics scenarios. Results are presented for the search for Neutral MSSM (Mininal SuperSymmetric Standard Model) higgs bosons where the higgs decays to two $\\tau$-leptons using the full Run-1 dataset collected by the CMS experiment. Interpretation of these results in the context of the SM higgs boson discovery is also given.

  3. Independent search for neutral Higgs boson flavour with the ALEPH detector at LEP2

    2001-01-01

    A flavour independent search for the neutral Higgs boson is performed in the four jets channel, e + e - → h(hadrons)Z(qq-bar), in the channel with missing energy, e + e - → h(hadrons)Z(νν-bar) and in the leptonic channel e + e - → h(hadrons)Z(e + e - ,μ + μ - ). The analysed data have been collected by the ALEPH detector at LEP during the years 1998, 1999 and 2000, at center of mass energies from 189 to 210 GeV. The selections in four jets and missing energy channels are based on the artificial neural networks multivariate method. This allows the non-linear combining of the signal information. In order to obtain a selection independent of the flavour of the Higgs boson decay products, this information is brought through purely kinematic and topologic variables. The selection in the leptonic channel is performed by a set of cuts that benefit from the very good electron and muon identification. No evidence of signal has been seen in the data collected by ALEPH up to 189 GeV. This allows us to restrict the allowed values of the mass, cross section and branching ratio of the Higgs boson. The result is expressed by a excluded region at 95% of confidence level in a two-dimension space. With this, it is possible to verify if a particular model is excluded or not by the experiment. This result is interpreted in the Standard Model and the MSSM. In the Standard Model, a lower limit is derived on the Higgs boson mass, M(Higgs) > 109.5 GeV/c 2 , with a 95% of confidence level.

  4. Gauge dynamics in the PNJL model: Color neutrality and Casimir scaling

    2009-01-01

    We discuss a gauge-invariant prescription to take the mean-field approximation self-consistently in the PNJL model (Nambu-Jona-Lasinio model with the Polyakov loop). We first address the problem of non-vanishing color density in normal quark matter, which is an artifact arising from gauge-fixed treatment of the Polyakov loop mean-fields. We then confirm that the gauge average incorporated in our prescription resolves this problem and ensures color neutrality. We point out that the proposed method has an advantage in computing the expectation value of any function of the Polyakov loop matrix. We discuss the Casimir scaling as an immediate application of the method.

    2011-06-01

    We present a unified description of e+ e- dilepton production in heavy ion collisions at relativistic (3.7A GeV) and ultrarelativistic (200A GeV) energies. From the interactions of [12C and 22Ne] at 3.7A GeV and 32S at 200A GeV with nuclear emulsion, 134 e+ e- pairs are observed. The differential distribution of the energy asymmetry of pairs is compared to a background observation at Bristol. The events are consistent in a way that, they scale well in a single curve of exponential decay. This ensures correct asymptotics and provides a unified description of mesonic decay. The existence of light neutral boson of mass (1.55±0.14 MeV/c2) is questionable, because the candidate peak is seen in the invariant mass spectrum of its decay into e+ e- pairs. The data seem to suggest the production and subsequent decay of short lived neutral boson with lifetime of the order of 10-16 S.

  6. Interference effects of neutral MSSM Higgs bosons with a generalised narrow-width approximation

    2014-11-01

    Mixing effects in the MSSM Higgs sector can give rise to a sizeable interference between the neutral Higgs bosons. On the other hand, factorising a more complicated process into production and decay parts by means of the narrow-width approximation (NWA) simplifies the calculation. The standard NWA, however, does not account for interference terms. Therefore, we introduce a generalisation of the NWA (gNWA) which allows for a consistent treatment of interference effects between nearly mass-degenerate particles. Furthermore, we apply the gNWA at the tree and 1-loop level to an example process where the neutral Higgs bosons h and H are produced in the decay of a heavy neutralino and subsequently decay into a fermion pair. The h-H propagator mixing is found to agree well with the approximation of Breit-Wigner propagators times finite wave-function normalisation factors, both leading to a significant interference contribution. The factorisation of the interference term based on on-shell matrix elements reproduces the full interference result within a precision of better than 1% for the considered process. The gNWA also enables the inclusion of contributions beyond the 1-loop order into the most precise prediction.

  7. Covariant open bosonic string field theory on multiple D-branes in the proper-time gauge

    2017-12-01

    We construct a covariant open bosonic string field theory on multiple D-branes, which reduces to a non-Abelian group Yang-Mills gauge theory in the zero-slope limit. Making use of the first quantized open bosonic string in the proper time gauge, we convert the string amplitudes given by the Polyakov path integrals on string world sheets into those of the second quantized theory. The world sheet diagrams generated by the constructed open string field theory are planar in contrast to those of the Witten's cubic string field theory. However, the constructed string field theory is yet equivalent to the Witten's cubic string field theory. Having obtained planar diagrams, we may adopt the light-cone string field theory technique to calculate the multi-string scattering amplitudes with an arbitrary number of external strings. We examine in detail the three-string vertex diagram and the effective four-string vertex diagrams generated perturbatively by the three-string vertex at tree level. In the zero-slope limit, the string scattering amplitudes are identified precisely as those of non-Abelian Yang-Mills gauge theory if the external states are chosen to be massless vector particles.

    In the absence of a low mass Higgs or new resonances, models for the regularization of vector boson scattering at high energy constrain the production rate of longitudinal vector boson pairs. The possibility to measure the rate of same-sign W production is discussed. Non-resonant scenarios of WZ production, in the Chiral Lagrangian model are also investigated.

    The process e+e- --> W+ W- \\gamma is studied using the data collected by the L3 detector at LEP. New results, corresponding to an integrated luminosity of 427.4 pb-1 at centre-of-mass energies from 192~GeV to 207~GeV, are presented. The W+W-\\gamma cross sections are measured to be in agreement with Standard Model expectations. No hints of anomalous quartic gauge boson couplings are observed. Limits at 95\\% confidence level are derived using also the process e+e- --> \

    We study the phenomenological consequences of several CP-violating structures that could arise in the Standard Model effective field theory framework. Focusing on operators involving electroweak gauge and/or Higgs bosons, we derive constraints originating from Run I LHC data. We then study the capabilities of the present and future LHC runs at higher energies to further probe associated CP-violating phenomena and we demonstrate how differential information can play a key role. We consider both traditional four-lepton probes of CP-violation in the Higgs sector and novel new physics handles based on varied angular and non-angular observables. (orig.)

  11. Intermediate-mass Higgs boson and isosinglet neutral heavy lepton signals at hadron supercolliders

    1992-01-01

    The signals for the Standard Model intermediate-mass Higgs boson and isosinglet neutral heavy leptons at the forthcoming hadron supercolliders-the Superconducting Super Collider (SSC) and the CERN Large Hadron Collider (LHC), are studied. The author studies inclusive production of the Standard Model Higgs boson in the intermediate-mass region (M W approx-lt m H approx-lt 2M Z ) and its subsequent decay into two on- or off-shell W bosons that decay leptonically. Backgrounds from continuum W pair production and top quark pair production with semileptonic decays are investigated. The author concludes the Higgs boson signal may be observed via the decay H → W*W* → (ell bar v ell ) (bar ell' v' ell ) at the SSC for 145 GeV H approx-lt 2M Z and at the LHC for 150 GeV H approx-lt 2M Z if m t > 150 GeV. The author analyzes the search and discovery potential of isosinglet neutral heavy leptons (NHLs) produced via real or virtual W decay at pp supercolliders. The author considers the signal resulting from the leptonic decay of the NHL, and the two major backgrounds-continuum WZ, Wγ production and t bar tj production, where j is a hadronic jet. The decay patterns of NHL depend on its mass M N , and different search strategies are needed for the two mass regions M N W and M N > M Z . The author finds for m t ≥ 150 (200) GeV the signal is observable for M N ≤ 60 (70) GeV in the mass-region M N W , and up to M N ≅ 110 GeV for M N > M W , at both SSC and LHC. It is shown the non-observance of the signal (with a 4σ statistical significance) in the region M N W could put upper limits on the NHL coupling constants that would be an improvement over the limits obtainable from the CERN Large Electron Positron Collider (LEP I)

    Resonant production of two electroweak gauge bosons (WW, WZ, ZZ) is an important signature for physics beyond the Standard Model and various possibilities resulting in such signatures have been proposed, e.g, Extended Gauge Models with heavy charged/neutral bosons (W’, Z’), bulk Randall-Sundrum excitation of the graviton (G*) in extra dimensions. Similarly the resonant production of a W or Z gauge boson with a SM Higgs boson or of two Higgs bosons is predicted in various new physics scenario. Searches for such high-mass resonances can obtain a significant sensitivity gain by exploiting techniques to identify hadronic decay of boosted W, Z or Higgs bosons. This presentation summarizes the ATLAS and CMS searches for di-bosons resonances in final states including hadronic jets and leptons with boosted boson tagging techniques

    A search for neutral Higgs bosons decaying into a boverline{b} quark pair and produced in association with at least one additional b quark is presented. This signature is sensitive to the Higgs sector of the minimal supersymmetric standard model (MSSM) with large values of the parameter tan β. The analysis is based on data from proton-proton collisions at a center-of-mass energy of 8 TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.7 fb-1. The results are combined with a previous analysis based on 7 TeV data. No signal is observed. Stringent upper limits on the cross section times branching fraction are derived for Higgs bosons with masses up to 900 GeV, and the results are interpreted within different MSSM benchmark scenarios, m h max , m h mod + , m h mod - , light-stau and light-stop. Observed 95% confidence level upper limits on tan β, ranging from 14 to 50, are obtained in the m h mod + benchmark scenario. [Figure not available: see fulltext.

    We report on the first results of a sensitive search for scalar coupling of photons to a light neutral boson in the mass range of approximately 1.0 meV (milli-electron volts) and coupling strength greater than 10^-6 GeV^-1 using optical photons. This was a photon regeneration experiment using the "light shining through a wall" technique in which laser light was passed through a strong magnetic field upstream of an optical beam dump; regenerated laser light was then searched for downstream of a second magnetic field region optically shielded from the former. Our results show no evidence for scalar coupling in this region of parameter space.

    Bosonization is a useful technique for studying systems of interacting fermions in low dimensions. It has applications in both particle and condensed matter physics.This book contains reprints of papers on the method as used in these fields. The papers range from the classic work of Tomonaga in the 1950's on one-dimensional electron gases, through the discovery of fermionic solitons in the 1970's, to integrable systems and bosonization on Riemann surfaces. A four-chapter pedagogical introduction by the editor should make the book accessible to graduate students and experienced researchers alik

    A search for neutral supersymmetric Higgs bosons and work relating to the improvement of the b-tagging and trigger capabilities at the D0 detector during Run II of the Fermilab Tevatron collider is presented. The search for evidence of the Higgs sector in the Standard Model (SM) and supersymmetric extensions of the SM are a high priority for the D0 collaboration, and b-tagging and good triggers are a vital component of these searches. The development and commissioning of the first triggers at D0 which use b-tagging is outlined, along with the development of a new secondary vertex b-tagging tool for use in the Level 3 trigger. Upgrades to the Level 3 trigger hit finding code, which have led to significant improvements in the quality and efficiency of the tracking code, and by extension the b-tagging tools, are also presented. An offline Neural Network (NN) b-tagging tool was developed, trained on Monte Carlo and extensively tested and measured on data. The new b-tagging tool significantly improves the b-tagging performance at D0, for a fixed fake rate relative improvements in signal efficiency range from ~ 40% to ~ 15%. Fake rates, for a fixed signal efficiency, are typically reduced to between a quarter and a third of their value. Finally, three versions of the search for neutral supersymmetric Higgs bosons are presented. The latest version of the analysis makes use of almost 1 fb-1 of data, the new NN b-tagger and the new b-tagging triggers, and has set one of the world's best limits on the supersymmetric parameter tanβ in the mass range 90 to 150 GeV.

  20. Transversal momentum of the electroweak gauge boson and forward jets in high energy factorisation at the LHC

    Deak, Michal

    2010-06-15

    Fixed order perturbation theory is not able to describe the transversal momentum spectrum of a electro-weak gauge boson. It is needed to resum whole classes of enhanced logarithmic terms. Depending on the phase space region different classes of logarithmic terms can be important. There are different approaches to sum such logarithmic terms including evolution equations of parton density functions. The evolution equation DGLAP which is valid for integrated parton density functions can be used to effectively produce unintegrated parton density functions using parton shower algorithm, but this approach involves kinematical approximations. With opening of phase space region {lambda}{sup 2}{sub QCD} << {mu}{sup 2} << s at the LHC approaches based on the BFKL and the CCFM equations are becoming more relevant. The BFKL and the CCFM equations define genuine unintegrated parton density functions which can be convoluted with matrix elements with off-shell initial state gluons. The off-shell matrix element for Z/W+Q anti Q production was calculated the Monte Carlo Cascade based on the CCFM evolution equation was used to study the phenomenology of this process concentrated on observables connected with the electro-weak gauge boson for the LHC kinematics. The widening of the peak of the transversal momentum spectrum of the electroweak boson is observed and discussed. The forward jet production using unintegrated parton density functions and off-shell matrix elements at the LHC was studied as a probe for small-x dynamics. Differences in azimuthal decorrelation and harder forward jet transversal momentum spectrum are discussed. (orig.)

    We present a universal method to create a tunable, artificial vector gauge potential for neutral particles trapped in an optical lattice. The necessary Peierls phase of the hopping parameters between neighboring lattice sites is generated by applying a suitable periodic inertial force such that the method does not rely on any internal structure of the particles. We experimentally demonstrate the realization of such artificial potentials, which generate ground-state superfluids at arbitrary nonzero quasimomentum. We furthermore investigate possible implementations of this scheme to create tunable magnetic fluxes, going towards model systems for strong-field physics.

    A search for neutral and charged Higgs bosons has been performed in the data collected by the {\\sc DELPHI} detector at centre-of-mass energies of 161~GeV and 172~GeV. The analysis assumes either the pair-production of charged Higgs bosons, ${\\mathrm H}^{\\pm}$, or the production of the lightest neutral Higgs boson, h, with either a Z or a neutral pseudoscalar Higgs boson, A. All final state topologies expected from the decay of h and A %neutral Higgs particles into hadrons or a pair of $\\tau$ leptons, and from the decay of ${\\mathrm H}^{\\pm}$ %charged Higgs bosons into a pair of quarks or a $\\tau \

    The production of jets in association with vector bosons is an important process to study perturbative QCD in a multi-scale environment. The LHC collaborations have performed measurements of vector boson+jets cross sections, differential in several kinematic variables, in proton-proton collision data taken at center-of-mass energies of 8TeV and 13TeV. Measurements explored also extreme phase-space: EW production and collinear W emissions. Discussed is also precise measurement of leptons angular correlations for Z+j production at high pT. The measurements are compared to state-of-the art theory predictions and can be used to constrain the proton structure. In this context discussed are also high precision measurement of the differential W and Z boson cross-sections.

  5. Role of polarization in probing anomalous gauge interactions of the Higgs boson

    International Nuclear Information System (INIS)

    We explore the use of polarized e + /e - beams and/or the information on final state decay lepton polarizations in probing the interaction of the Higgs boson with a pair of vector bosons. A model independent analysis of the process e + e - →ffH, where f is any light fermion, is carried out through the construction of observables having identical properties under the discrete symmetry transformations as different individual anomalous interactions. This allows us to probe an individual anomalous term independent of the others. We find that initial state beam polarization can significantly improve the sensitivity to CP-odd couplings of the Z boson with the Higgs boson (ZZH). Moreover, an ability to isolate events with a particular τ helicity, with even 40% efficiency, can improve sensitivities to certain ZZH couplings by as much as a factor of 3. In addition, the contamination from the ZZH vertex contributions present in the measurement of the trilinear Higgs-W (WWH) couplings can be reduced to a great extent by employing polarized beams. The effects of initial state radiation and beamstrahlung, which can be relevant for higher values of the beam energy are also included in the analysis.

    Searches for neutral Higgs bosons are performed with the 237 pb^-1 of data collected in 1999 by the ALEPH detector at LEP, for centre-of-mass energies between 191.6 and 201.6 GeV. These searches apply to Higgs bosons within the context of the Standard Model and its minimal supersymmetric extension (MSSM) as well as to invisibly decaying Higgs bosons. No evidence of a signal is seen. A lower limit on the mass of the Standard Model Higgs boson of 107.7 GeV/c^2 at 95% confidence level is set. In the MSSM, lower limits of 91.2 and 91.6 GeV/c^2 are derived for the masses of the neutral Higgs bosons h and A, respectively. For a Higgs boson decaying invisibly and produced with the Standard Model cross section, masses below 106.4 GeV/c^2 are excluded.

    Measurements of the trilinear gauge boson couplings $WW\\gamma$ and $WWZ$ are presented using the data taken by DELPHI in 1998 at a centre-of-mass energy of 189~GeV and combined with DELPHI data at 183~GeV. Values are determined for \\Dgz\\ and \\Dkg, the differences of the $WWZ$ charge coupling and of the $WW\\gamma$ dipole coupling from their Standard Model values, and for \\lm, the $WW\\gamma$ quadrupole coupling. A measurement of the magnetic dipole and electric quadrupole moment of the $W$ is extracted from the results for \\Dkg{} and \\lm. The study uses data from the final states \\jjlv, \\jjjj \\lX, \\jjX\\ and \\gX, where $j$ represents a quark jet, $\\ell$ an identified lepton and $X$ missing four-momentum. The observations are consistent with the predictions of the Standard Model.

    Upper limits on the cross-section of the pair-production process e+e- -> h0A0 assuming 100% decays into hadrons, are derived from a new search for the h0A0 -> hadrons topology, independent of the hadronic flavour of the decay products. Searches for the neutral Higgs bosons h0 and A0, are used to obtain constraints on the Type II Two Higgs Doublet Model (2HDM(11)) with no CP violation in the Higgs sector and no additional non Standard Model particles besides the five Higgs bosons. The analysis combines LEP1 and LEP2 data collected with the OPAL detctor up to the highest available centre-of-mass energies. The searches are sensitive to the h0, A0 -> qq, gg,tau+tau- and h0 -> A0A0 decay modes of the Higgs bosons. The 2HDM(II) parameter space is explored in a detailed scan. Large regions of the 2HDM(II) parameter space are excluded at the 95% CL in the (mh, mA), (mh, tanb) and (mA, tanb) planes, using both direct neutral Higgs boson searches and indirect limits derived from Standard Model high precision measuremen...

    Searches for neutral Higgs bosons in the Standard Model and the MSSM havebeen performed using data collected by the DELPHI experiment at acentre-of-mass energy of 188.7 GeV, corresponding toan integrated luminosity of 158~pb$^{-1}$.These analyses are used, in combination with our results from lowerenergies, to set new 95\\% confidence level lower mass bounds on theStandard Model Higgs boson (94.6 GeV/$c^2$) and on the lightest neutralscalar (82.6 GeV/$c^2$) and neutral pseudoscalar (84.1 GeV/$c^2$) Higgsbosons in a representative scan of the MSSM parameters. The results are alsointerpreted in the framework of a general two-Higgs doublet model.

    A search is described for the neutral Higgs bosons h^0 and A^0 predicted by models with two scalar field doublets and, in particular, the Minimal Supersymmetric Standard Model (MSSM). The search in the Z^0 h^0 and h^0 A^0 production channels is based on data corresponding to an integrated luminosity of 25 pb^{-1} from e^+e^- collisions at centre-of-mass energies between 130 and 172GeV collected with the OPAL detector at LEP. The observation of a number of candidates consistent with Standard Model background expectations is used in combination with earlier results from data collected at the Z^0 resonance to set limits on m_h and m_A in general models with two scalar field doublets and in the MSSM. For example, in the MSSM, for tan(beta) > 1, minimal and maximal scalar top quark mixing and soft SUSY-breaking masses of 1 TeV, the 95% confidence level limits m_h > 59.0 GeV and m_A > 59.5 GeV are obtained. For the first time, the MSSM parameter space is explored in a detailed scan.

    A determination of the single W Spin Density Matrix (SDM) elements in the reaction e+e- -> W+W- -> l nu q qbar (l=e/mu) is reported at centre-of-mass energies between 189 and 209 GeV. The data sample used corresponds to an integrated luminosity of 520 pb^{-1} taken by DELPHI between 1998 and 2000. The single W SDM elements, rho_{tau tau'}^{W+-} (tau,tau' = +/-1 or 0), are determined as a function of the W- production angle with respect to the e- beam direction and are obtained from measurements of the W decay products by the application of suitable projection operators, Lambda_{tau tau'}, which assume the V-A coupling of the W boson to fermions. The measured SDM elements are used to obtain the fraction of longitudinally polarised Ws, with the result: sigma_L/sigma_tot = 24.9 +/- 4.5(stat) +/- 2.2(syst) % at a mean energy of 198 GeV. The SDM elements are also used to determine the Triple Gauge Couplings Delta g_1^Z, Delta kappa_gamma, lambda_gamma and g_4^Z, ~kappa_Z and ~lambda_Z. For the CP-violating couplin...

    A search for neutral MSSM Higgs bosons in pp collisions at the LHC at a center-of-mass energy of 7 TeV is presented. The results are based on a data sample corresponding to an integrated luminosity of 36 inverse picobarns recorded by the CMS experiment. The search uses decays of the Higgs bosons to tau pairs. No excess is observed in the tau-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent new bounds in the MSSM parameter space.

    A search for neutral MSSM Higgs bosons in pp collisions at the LHC at a center-of-mass energy of 7 TeV is presented. The results are based on a data sample corresponding to an integrated luminosity of 36 inverse picobarns recorded by the CMS experiment. The search uses decays of the Higgs bosons to tau pairs. No excess is observed in the tau-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent new bounds in the MSSM parameter space.

    A non-linear Rsub(xi) gauge conditions is presented and explicitly developed in the framework of the SU(2) x U(1) gauge model. We give the corresponding Feynman rules, which are simpler than in Rsub(xi) gauges, because couplings involving unphysical Higgs and gauge bosons disappear or simplify. The Faddeev-Popov sector is more elegant, the ghosts coupling to neutral gauge bosons like in scalar electrodynamics. Finally, as a practical example, the transition Higgs → γγ is considered and compared with the usual calculation in linear gauges

    In vector-like gauge theories a two-component conception for the gluon condensate is suggested. It is shown that the component connected with spontaneous chiral symmetry breaking can generate a bound state fermion-antifermion scalar mass of magnitude M σ ≅ 2M F . The associated dynamical dimension of the scalar field is d σ =2. The application of this approach to QCD is than discussed. 23 refs

    The search for additional heavy neutral Higgs bosons predicted in Minimal Supersymmetric Extensions of the Standard Model is presented, using the direct decay channel into two tau leptons which themselves decay hadronically. The study is based on proton-proton collisions recorded in 2011 at a center-of-mass energy of 7 TeV with the ATLAS detector at the Large Hadron Collider at CERN. With a sample size corresponding to an integrated luminosity of $4.5\\,\\text{fb}^{−1}$, no significant excess above the expected Standard Model background prediction is observed and $\\text{CL}_\\text{S}$ exclusion limits at a 95% confidence level are evaluated for values of the CP-odd Higgs boson mass mA between 140 GeV to 800 GeV within the context of the $m_\\text{h}^{\\text{max}}$ and $m^{\\text{mod}\\pm}_\\text{h}$ benchmark scenarios. The results are combined with searches for neutral Higgs h bosons performed using proton-proton collisions at a center-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, with a corres...

    Full Text Available We study the phenomenology of both the Neutral Current (NC and Charged Current (CC Drell-Yan (DY processes at the Large Hadron Collider (LHC within a 4 Dimensional realization of a Composite Higgs model with partial compositness by estimating the integrated and differential event rates and taking into account the possible impact of the extra fermions present in the spectrum. We show that, in certain regions of the parameters space, the multiple neutral resonances present in the model can be distinguishable and experimentally accessible in the invariant or transverse mass distributions.

  4. Double parton scattering of weak gauge boson productions at the 13 TeV and 100 TeV proton-proton colliders

    We study double parton scattering (DPS) processes involving electroweak gauge bosons at the 13 and 100 TeV proton-proton colliders. Specifically, we focus on three DPS channels: W -boson plus two jets (W ⊗j j ), Z -boson plus two jets (Z ⊗j j ), and same-sign W pair production (W±⊗W± ). We demonstrate that the Z ⊗j j process, which has not received much attention, is the best channel for measuring the effective cross section σeff . The accuracy of the σeff measurement in the three DPS channels, especially the W±⊗W± production, is significantly improved at the 100 TeV colliders. We advocate that combined analysis of the three DPS channels could test the universality of the effective cross section σeff.

    Particle physics deals with the elementary constituents of our universe and their interactions. The electroweak symmetry breaking mechanism in the Standard Model of Particle Physics is of paramount importance and it plays a central role in the physics programmes of current high-energy physics experiments at the Large Hadron Collider. The study of scattering processes of massive electroweak gauge bosons provides an approach complementary to the precise measurement of the properties of the recently discovered Higgs boson. Owing to the unprecedented energies achieved in proton-proton collisions at the Large Hadron Collider and the large amount of data collected, experimental studies of these processes become feasible for the first time. Especially the scattering of two $W^{\\pm}$ bosons of identical electric charge is considered a promising process for an initial study due to its distinct experimental signature. In the course of this work, $20.3 \\, \\mathrm{fb}^{−1}$ of proton-proton collision data recorded by t...

  6. Neutral $Z$ boson pair production due to radion resonance in the Randall-Sundrum model: prospects at the CERN LHC

    CERN Document Server

    Das-Prasanta, Kumar

    2005-01-01

    The Neutral $Z$ boson pair production due to radion resonance at the Large Hadron Collider is an interesting process to explore the notion of warped geometry (Randall-Sundrum model). Because of the enhanced coupling of radion with a pair of gluons due to trace enomaly and top(quark)-loop, the radion can provide larger event rate possibility as compared to any New Physics effect. Using the proper radion-top-antitop (with the quarks being off-shell) coupling, we obtain the correct radion production rate at LHC and explore several features of a heavier radion decaying into a pair of real Z bosons which subsequently decays into charged 4 l (l=e, \\mu) leptons (the gold-plated mode). Using the signal and background event rate, we obtain bounds on radion mass $m_\\phi$ and radion vev $\\vphi$ at the $5\\sigma$, $10\\sigma$ discovery level.

    We present measurements of triple gauge boson coupling parameters using data recorded by the OPAL detector at LEP2 at a centre-of-mass energy of 172 GeV. A total of 120 W-pair candidates has been selected in the q q(bar) q q(bar), q q(bar) l nu(bar)_l, and l nu(bar)_l l(bar)' nu_l' decay channels, for an integrated luminosity of 10.4 pb^-1. We use these data to determine several different anomalous coupling parameters using the measured cross-section and the distributions of kinematic variables. We measure alpha_B-phi = 0.35 + 1.29 - 1.07 +/- 0.38, alpha_W-phi = 0.00 + 0.30 - 0.28 +/- 0.11, alpha_W = 0.18 + 0.49 - 0.47 +/- 0.23, Delta(g_1^z) = -0.03 + 0.40 -0.37 +/- 0.14, Delta(kappa_gamma^(HISZ)) = 0.03 + 0.55 - 0.51 +/- 0.20, and Delta(kappa) = 0.03 + 0.49 - 0.46 +/- 0.21. Combining the alpha_W-phi result with our previous result obtained from the 161 GeV data sample we measure alpha_W-phi = -0.08 + 0.28 - 0.25 +/- 0.10. All of these measurements are consistent with the Standard Model.

We emphasize that the top sector is promising for the discovery of new particles because top quark pairs are copiously produced at the Large Hadron Collider. The signal process is initiated by a rare top decay into a bottom quark and a charged Higgs boson ($H^\\pm$) decaying subsequently into a $W$ and one or multiple $Z'$s. The light $Z'$ can be invisible in collider searches in various scenarios, and it would be hard to distinguish the relevant collider signature from the regular $t\\bar{t}$ process in the Standard Model. We suggest a search strategy using the recently proposed on-shell constrained $M_2$ variables. Our signal process is featured by an $\\textit{asymmetric}$ event topology, while the $t\\bar{t}$ is $\\textit{symmetric}$. The essence behind the strategy is to evoke so...

    We review the information that is already provided and will be soon provided on the parameters of a new neutral boson of the most general nature from LEP and SLC experiments. We develop a strategy that associates the general independent lepton and quark Z' couplings to precisely defined experiments. For the specific case of particular popular models (E 6 , left-right symmetry, composite Z) that we have analyzed, we predict, in case of negative searches, bounds of typical order one percent for the Z' mixing angle and one TeV for the Z' mass, at the end of the various experimental phases

    The minimal supersymmetric extension of the standard model (MSSM) predicts the existence of five Higgs bosons (h,H, A,H{sup +},H{sup -}) whose properties are at the tree level determined by two independent parameters, the ratio tan {beta} of the two vacuum expectation values and the mass m{sub A} of the pseudoscalar Higgs boson A. For large values of tan {beta} the neutral MSSM Higgs bosons are predominantely produced in association with b-quarks. The b-jets originating from these processes have a relatively low energy (below 20 GeV) compared to those in t anti t, the dominant background. This talk introduces methods to optimize the measurement of the b-tagging performance in this challenging low-p{sub T} regime. As the most promising final states for the search are defined by the Higgs decays into tau or muon pairs, another important aspect studied for this analysis is the lepton isolation in a high pile-up environment.

    This paper presents a search for Higgs bosons decaying to four leptons, either electrons or muons, via one or two light exotic gauge bosons $Z_d$, $H\\to Z Z_d \\to 4\\ell$ or $H\\to Z_d Z_d \\to 4\\ell$. The search was performed using $pp$ collision data corresponding to an integrated luminosity of about 20 fb$^{-1}$ at the center-of-mass energy of $\\sqrt{s}=8 $TeV recorded with the ATLAS detector at the Large Hadron Collider. The observed data are well described by the Standard Model prediction. Upper bounds on the branching ratio of $H\\to Z Z_d \\to 4\\ell$ and on the kinetic mixing parameter between the $Z_d$ and the Standard Model hypercharge gauge boson are set in the range $(1$--$9)\\times10^{-5}$ and $(4$--$17)\\times10^{-2}$ respectively, at 95% confidence level assuming the Standard Model branching ratio of $H\\to Z Z^* \\to 4\\ell$, for $Z_d$ masses between 15 and 55 GeV. Upper bounds on the effective mass mixing parameter between the $Z$ and the $Z_d$ are also set using the branching ratio limits in the $H \\to...

    The search for additional heavy neutral Higgs bosons predicted in Minimal Supersymmetric Extensions of the Standard Model is presented, using the direct decay channel into two tau leptons which themselves decay hadronically. The study is based on proton-proton collisions recorded in 2011 at a center-of-mass energy of 7 TeV with the ATLAS detector at the Large Hadron Collider at CERN. With a sample size corresponding to an integrated luminosity of 4.5 fb -1 , no significant excess above the expected Standard Model background prediction is observed and CL S exclusion limits at a 95% confidence level are evaluated for values of the CP-odd Higgs boson mass m A between 140 GeV to 800 GeV within the context of the m h max and m h mod± benchmark scenarios. The results are combined with searches for neutral Higgs bosons performed using proton-proton collisions at a center-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, with a corresponding integrated luminosity of 19.5 fb -1 . The combination allowed an improvement of the exclusion limit at the order of 1 to 3 units in tan β. Within the context of this study, the structure of additional interactions during a single proton-proton collision (the ''underlying event'') in di-jet final states is analyzed using collision data at a center-of-mass energy of 7 TeV recorded with the ATLAS detector in 2010, with a corresponding integrated luminosity of 37 pb -1 . The contribution of the underlying event is measured up to an energy scale of 800 GeV and compared to the predictions of various models. For several models, significant deviations compared to the measurements are found and the results are provided for the optimization of simulation algorithms.

    Precise measurements at LEP1 and SLD dramatically confirm the Standard Model predictions. Nevertheless, the most crucial consequence of a non-Abelian gauge theory, namely the specific form of the self-couplings of the W, Z and {gamma} was poorly tested. W pair production at LEP2 was a unique opportunity to measure accurately both W boson parameters and its gauge couplings. This thesis presents a study of WW events reconstruction on one hand, and a measurement of the anomalous couplings on the other hand. A precise measurement of the W mass (accuracy {approx} 10{sup -4}) is a major goal of the LEP2 program. The reconstruction of W mass disintegration products, used for this measurement, is very sensitive to the simulation defaults: an essential task is to understand and minimize their effects. This work presents a detailed study of the electromagnetic showers simulation in ALEPH. From this study, a new event reconstruction is proposed, which is tested on the LEP energy measurement obtained from Z return process. Triple gauge-boson couplings are measured from the data collected with the ALEPH detector between 1997 and 2000. Then, results are combined with the other three LEP experiments. This measurement directly confirms the non-Abelian nature of the electroweak sector. No deviation from the Standard Model is observed. (author)

    Limits on the cross-section times branching fraction for neutral Higgs bosons, produced in $pp$ collisions at $\\sqrt{s} = 7$ TeV, and decaying to two tau leptons with pseudorapidities between 2.0 and 4.5, are presented. The result is based on a dataset, corresponding to an integrated luminosity of 1.0 $\\mathrm{fb}^{-1}$, collected with the LHCb detector. Candidates are identified by reconstructing final states with two muons, a muon and an electron, a muon and a hadron, or an electron and a hadron. A model independent upper limit at the 95% confidence level is set on a neutral Higgs boson cross-section times branching fraction. It varies from 8.6 pb for a Higgs boson mass of 90 GeV to 0.7 pb for a Higgs boson mass of 250 GeV, and is compared to the Standard Model expectation. An upper limit on $\\tan\\beta$ in the Minimal Supersymmetric Model is set in the $m_{h^0}^\\mathrm{max}$ scenario. It ranges from 34 for a CP-odd Higgs boson mass of 90 GeV to 70 for a pseudo-scalar Higgs boson mass of 140 GeV.

    This dissertation describes the search for Higgs bosons decaying to a pair of {tau} leptons both decaying to muons. The analysis was performed using events recorded by the CMS detector at the LHC in 2011 and 2012, at center-of-mass energy 7 TeV and 8 TeV respectively. The dataset corresponds to total integrated luminosity of 17 fb{sup -1}, 4.9 fb{sup -1} taken at 7 TeV center-of-mass energy and 12.1 fb{sup -1} at 8 TeV. The results were interpreted in the context of both the Standard Model and the Minimal Supersymmetric Standard Model. Upper limits were set to the Higgs production cross section in the former case and on the (tan {beta}, m{sub A}) plane in the latter. The update of this analysis with more data, combined with other {tau}{tau} final states, lead to the first evidence of the Higgs coupling to {tau} leptons. Included in this document is also the study of the Z boson production followed by Z {yields} {tau}{tau} decay with two muons in the final state. This analysis was performed with 36 pb{sup -1} of data collected in 2010, at center-of-mass energy 7 TeV, by the CMS experiment. The result of this study was the measurement of the Z production cross section in proton-proton collisions. The analysis procedures developed for the Z boson decay to {tau} leptons were used to commission the Higgs boson searches in the same decay channel.

    This work presents a study of the discovery potential for the neutral supersymmetric Higgs bosons h/A/H decaying to tau pairs with the ATLAS experiment at the LHC. The study is based on Monte Carlo samples which are scaled to state-of-the-art cross sections. The analyses are designed assuming an integrated luminosity of 30 1/fb and a center-of-mass energy of sqrt(s) = 14 TeV. The results are interpreted in the m_h^max benchmark scenario. Two final states are analyzed: The dileptonic channel where the two tau leptons decay to electrons or muons and the lepton-hadron channel where one tau decays to an electron or muon and the other tau decays to hadrons. The study of the dilepton channel is based completely on the detailed ATLAS simulation, the analysis of the lepton-hadron channel is based on the fast simulation. The collinear approximation is used to reconstruct the Higgs boson mass and its performance is studied. Cuts are optimized in order to discriminate the signal from background and to maximize the disco...

    We obtain the mass spectrum and the Higgs self-couplings of the two Higgs doublet model (THDM) in an alternative unification scenario where the parameters of the Higgs potential {lambda} (i = 1, 2, 3, 4, 5) are determined by imposing their unification on the electroweak gauge couplings. An attractive feature of this scenario is the possibility of determining the Higgs boson masses by evolving the {lambda}{sub i} from the electroweak-Higgs unification scale M{sub GH} down to the electroweak scale. The unification condition for the gauge (g{sub 1}, g{sub 2}) and Higgs couplings is written as g{sub 1} g{sub 2} = f ({lambda}{sub i}), where g{sub 1} = k{sub Y}{sup 1/2}g{sub Y}, and k{sub Y} is the normalization constant. Two variants for the unification condition are discussed: Scenario l is defined through the linear relation: g{sub 1} = g{sub 2} = k{sub H} (i){lambda}{sub i} (M{sub GH}), while Scenario ll assumes a quadratic relation g{sub 1}{sup 2} = g{sub 2}{sup 2} k{sub H} (i) {lambda}{sub i}(M{sub GH}) In Scenario l, by setting ad hoc - k{sub H}(5) = 1/2k{sub H}(4) 3/2k{sub H}(3) = k{sub H}(2) = k{sub H}(I) = 1, taking tan {beta} = 1 and using the standard normalization (k{sub Y} = 5/3), we obtain the following spectrum for the Higgs boson masses: m{sub h}{sup 0} = 109.1 GeV, m{sub H}{sup 0} = 123.2 GeV, m{sub A}{sup 0} = 115.5 GeV, and m{sub H}{sup +-} = 80.3 GeV, with similar results for other normalizations such as k{sub Y} = 3/2 and k{sub Y} = 7/4.

    The Standard Model of particle physics describes the strong, weak, and electromagnetic forces between the fundamental particles of ordinary matter. However, it presents several problems and some questions remain unanswered so it cannot be considered a complete theory of fundamental interactions. Many extensions have been proposed in order to address these problems. Some important recent extensions are the Extra Dimensions theories. In the context of some models with Extra Dimensions of size about $1 TeV^{-}1$, in particular in the ADD model with only fermions confined to a D-brane, heavy Kaluza-Klein excitations are expected, with the same properties as SM gauge bosons but more massive. In this work, three hadronic decay modes of some of such massive gauge bosons, Z* and W*, are investigated using the ATLAS experiment at the Large Hadron Collider (LHC), presently under construction at CERN. These hadronic modes are more difficult to detect than the leptonic ones, but they should allow a measurement of the cou...

    The report is devoted to four-fermion interactions mediated by the neutral currents. The results from the second phase of LEP are presented, when the production of two massive bosons was possible with the increased energy of the e + e - collisions. It enabled for a direct test of nonabelian structure of the electroweak theory. The results concern the four-fermion production of the pairs of the ZZ bosons, single Z and Zγ * production as well as search for anomalous gauge bosons couplings. The large part of the report is devoted to experimental techniques, physics analyses and discussion of results. (author)

    The results of first physics runs of the L3 detector at LEP Based on 2538 hadron events is reported. We determined the mass m z 0 and the width Γ z 0 of the intermediate vector boson Z 0 to be m z 0 =91.132 ± 0.057 GeV and Γ Z 0 = 2.588 ± 0.137 GeV. We also determined Γ i nvisible = 0.567 ± 0.080 GeV, corresponding to 3.42 ± 0.48 number of neutrino flavors. We also measured the muon pair cross-section and determined the branching ratio Γμμ/Γ h = 0.056 ± 0.006. The partial width of Z 0 → e + e - is Γ e e = 88 ± 9 ± 7 MeV. (Author)

    Events stemming from the pair-production of Z bosons in e^+e^- collisions are studied using 217.4 pb^-1 of data collected with the L3 detector at centre-of-mass energies from 200 GeV up to 209 GeV. The special case of events with b quarks is also investigated. Combining these events with those collected at lower centre-of-mass energies, the Standard Model predictions for the production mechanism are verified. In addition, limits are set on anomalous couplings of neutral gauge bosons and on effects of extra space dimensions.

  12. Production of neutral pseudo-Goldstone bosons at LEP II and NLC in multiscale walking technicolor models

    Lubicz, V.

    Walking technicolor (WTC) models predict the existence of heavy neutral pseudo-Goldstone bosons (PGBs), whose masses are typically expected to be larger than 100 GeV. In this paper, we investigate the production and decay of these particles at the high energy e + e - experiments, LEP II and NLC. We find that, in WTC models, the production of neutral PGBs can be significantly enhanced, by one or two orders of magnitude, with respect to the predictions of traditional (QCD-like) TC models. The origin of such an enhancement is the existence of several low energy TC scales, that are likely to appear in WTC theories. This could allow the PGBs to be observed even at the energy and luminosity of the LEP II experiment. At LEP II, the PGBs are expected to be produced in the e + e - →P γ channel, and, possibly, in the e + e - →P e + e - channel, with a total rate that can be of the order of several tenths per year. Due to the typical large values of PGB masses, the relative branching ratios of PGB decays, in WTC theories, are different from those predicted in traditional TC models. In particular, a large fraction of these decays can occur in the P →γγ channel. In considering the PGB production, at LEP II, we find that, in most of the final states, the distinctive signatures of WTC events should allow the Standard Model background to be reduced to a negligible level. We also find that, at a 500 GeV NLC experiment, the production of neutral PGBs can occur in several channels, and can be of the order of 10 3 events per year. Instead, when we consider traditional TC models, we find that no PGB are typically predicted to be observed, both at LEP II and the NLC experiment. (orig.)

    The production of the neutral technicolor pseudo Goldstone bosons, P{sup 0}{prime}and P{sub 8}{sup 0}{prime}, at large transverse momentum in pp collisions, pp {yields} g(q)P{sup 0}{prime} (P{sub 8}{sup 0}{prime})X has been investigated in reactions at a high energy collider such as the SSC. The major two-body and three-body decay modes in tree diagrams are investigated in detail. The t{bar t} decay channel would dominate both the decays of P{sup 0}{prime} and P{sub 8}{sup 0}{prime} if it is allowed. Otherwise, gg and 3g will be the dominant decay modes unless the mass of the P{sup 0}{prime} and P{sub 8}{sup 0}{prime} are below 40 GeV, where b{bar b} becomes dominant. According to the QCD backgrounds, which we have also investigated in detail in this work, the signal for t{bar t} is much larger than the background and will be the ideal signal for detecting these bosons. However, in the absence of the t{bar t} channel, the {tau}{bar {tau}} mode can be used to identify P{sup 0}{prime} up to m{sub P} = 300 GeV in the transverse momentum range P{sub {perpendicular}} {approx lt} 100 GeV. Similarly, the b{bar b} decay mode can serve us a signal to identify P{sub 8}{sup 0}{prime} up to m{sub P} = 300 GeV for P{sub {perpendicular}} between 500 and 700 GeV. Our results show that these high transverse momentum production processes are useful for the searching for the P{sub 8}{sup 0}{prime} at the SSC. 63 refs.

    A search for neutral Higgs bosons decaying to pairs of tau leptons with the ATLAS detector at the LHC is presented. The analysis is based on proton-proton collisions at a center-of-mass energy of 7 TeV, recorded in 2010 and corresponding to an integrated luminosity of 36 pb^-1. After signal selection, 276 events are observed in this data sample. The observed number of events is consistent with the total expected background of 269 +/- 36 events. Exclusion limits at the 95% confidence level are derived for the production cross section of a generic Higgs boson phi as a function of the Higgs boson mass and for A/H/h production in the Minimal Supersymmetric Standard Model (MSSM) as a function of the parameters m_A and tan(beta).

    The final results of the ALEPH search for the Standard Model Higgs boson at LEP, with data collected in the year 2000 at centre-of-mass energies up to 209,GeV, are presented. The changes with respect to the preceding publication are described and a complete study of systematic effects is reported. The findings of this final analysis confirm the preliminary results published in November 2000 shortly after the closing down of the LEP collider: a significant excess of events is observed, consistent with the production of a $115, Gcs$ Standard Model Higgs boson.% The final results of the searches for the neutral Higgs bosons of the MSSM are also reported, in terms of limits on $mh$, $mA$ and $anb$.% Limits are also set on $mh$ in the case of invisible decays.

    We investigate the possibility of detecting CP--odd angular correlations in the various decay modes of the neutral Higgs boson including the modes of a $ZZ$ pair, a $W^+W^-$ pair, or a heavy quark pair. It is a natural way to probe the CP character of the Higgs boson once it is identified. Final state interactions (i.e. the absorptive decay amplitude) is not required in such correlations. As an illustrative example we take the fundamental source of the CP nonconservation to be in the Yukawa couplings of the Higgs boson to the heavy fermions. A similar correlation in the process $e^+e^- \\to l^+ l^- H$ is also proposed. Our analysis of these correlations will be useful for experiments in future colliders such as LEP II, SSC, LHC or NLC.

  18. A measurement of the resonance parameters of the neutral intermediate vector boson

    This thesis presents a measurement of the Z 0 Boson resonance parameters. The measurement was performed at the Stanford Linear Collider using the Mark II detector. Based on a sample of 480 Hadronic and Leptonic decays, the mass is found to be 91.14 ± 0.12 GeV/c 2 , the total width is 2.42 -0.35 +0.45 GeV, and the peak cross section for all Hadronic events, and for Muon and Tau events with cosθ Thrust < 0. 65 is 45 ± 4 nb. By constraining the visible width to the Standard Model value for 5 quarks and 3 charged leptons, and allowing the invisible width to be a parameter, the width to invisible decay modes is found to be 0.46 ± 0.10 GeV. Assuming this width comes from massless neutrinos, this measurement corresponds to 2.8 ± 0.6 neutrino species. This measurement sets an upper limit of 3.9 neutrino generations at the 95% confidence level, ruling out a fourth generation of Standard Model neutrinos at this level. 54 refs., 65 figs., 11 tabs

    A measurement of the ZZ production cross section in proton-proton collisions at sqrt(s) = 7 TeV using data recorded by the ATLAS experiment at the LHC is presented. In a data sample corresponding to an integrated luminosity of 1.02 fb^-1 collected in 2011, 12 events containing two Z boson candidates decaying to electrons and/or muons are observed. The expected background contribution is 0.3 +/- 0.3 (stat) ^{+0.4}_{-0.3} (syst.) events. The cross section measured in a phase-space region with good detector acceptance and for dilepton masses within the range 66 GeV to 116 GeV is sigma_{ZZ to ll ll}^{fid} = 19^{+6}_{-5} (stat.) +/- 1 (syst.) +/- 1 (lumi.) fb. This result is then used to derive the total cross section for on-shell ZZ production, sigma_{ZZ}^{tot}= 8.5^{+2.7}_{-2.3} (stat.)^{+0.4}_{-0.3} (syst.) +/- 0.3 (lumi.) pb, which is consistent with the Standard Model expectation of 6.5^{+0.3}_{-0.2} pb calculated at the next-to-leading order in QCD.

  20. Light-induced gauge fields for ultracold atoms.

    Gauge fields are central in our modern understanding of physics at all scales. At the highest energy scales known, the microscopic universe is governed by particles interacting with each other through the exchange of gauge bosons. At the largest length scales, our Universe is ruled by gravity, whose gauge structure suggests the existence of a particle-the graviton-that mediates the gravitational force. At the mesoscopic scale, solid-state systems are subjected to gauge fields of different nature: materials can be immersed in external electromagnetic fields, but they can also feature emerging gauge fields in their low-energy description. In this review, we focus on another kind of gauge field: those engineered in systems of ultracold neutral atoms. In these setups, atoms are suitably coupled to laser fields that generate effective gauge potentials in their description. Neutral atoms 'feeling' laser-induced gauge potentials can potentially mimic the behavior of an electron gas subjected to a magnetic field, but also, the interaction of elementary particles with non-Abelian gauge fields. Here, we review different realized and proposed techniques for creating gauge potentials-both Abelian and non-Abelian-in atomic systems and discuss their implication in the context of quantum simulation. While most of these setups concern the realization of background and classical gauge potentials, we conclude with more exotic proposals where these synthetic fields might be made dynamical, in view of simulating interacting gauge theories with cold atoms.

    A search for the lightest neutral CP-even and neutral CP-odd Higgs bosons of the Minimal Supersymmetric Standard Model is performed using 216.6 pb-1 of data collected with the L3 detector at LEP at centre-of-mass energies between 203 and 209 GeV. No indication of a signal is found. Including our results from lower centre-of-mass energies, lower limits on the Higgs boson masses are set as a function of tan(beta) for several scenarios. For tan(beta) greater than 0.7 they are mh > 84.5 GeV and mA > 86.3 GeV at 95% confidence level.

    The cross section for the production of Z$\\gamma$ in proton-proton collisions at 8 TeV is measured based on data collected by the CMS experiment at the LHC corresponding to an integrated luminosity of 19.5 fb$^{-1}$. Events with an oppositely-charged pair of muons or electrons together with an isolated photon are selected. The differential cross section as a function of the photon transverse momentum is measured inclusively and exclusively, where the exclusive selection applies a veto on central jets. The observed cross sections are compatible with the expectations of next-to-next-to-leading-order quantum chromodynamics. Limits on anomalous triple gauge couplings of ZZ$\\gamma$ and Z$\\gamma\\gamma$ are set that improve on previous experimental results obtained with the charged lepton decay modes of the Z boson.

    The anomalous trilinear gauge couplings of Z and γ are studied in e{sup +}e{sup -} → ZZ/Zγ with longitudinal beam polarizations using a complete set of polarization asymmetries for the Z boson. We quantify the goodness of the beam polarization in terms of the likelihood and find the best choice of e{sup -} and e{sup +} polarizations to be (+0.16, -0.16), (+0.09, -0.10) and (+0.12, -0.12) for ZZ, Zγ and combined processes, respectively. Simultaneous limits on anomalous couplings are obtained for these choices of beam polarizations using Markov-Chain-Monte-Carlo (MCMC) for an e{sup +}e{sup -} collider running at √(s) = 500 GeV and L = 100 fb{sup -1}. We find the simultaneous limits for these beam polarizations to be comparable with each other and also comparable with the unpolarized beam case. (orig.)

    The cross section of the process e^+ e^- -> Z \\gamma\\gamma -> qq~ \\gamma \\gamma is measured with 215 pb^-1 of data collected with the L3 detector during the final LEP run at centre-of-mass energies around 205 GeV and 207 GeV. No deviation from the Standard Model expectation is observed. The full data sample of 713 pb^-1, collected above the Z resonance, is used to constrain the coefficients of anomalous quartic gauge boson couplings to: -0.02 GeV^-2 < a_0/\\Lambda^2 < 0.03 GeV^-2 and -0.07 GeV^-2 < a_c/\\Lambda^2 < 0.05 GeV^-2, at 95% confidence level.

    In the divertor simulation experiments in the GAMMA 10/PDX tandem mirror, pressure of the neutral gas was investigated by using a fast ionization gauge. The gauge was absolutely calibrated for hydrogen gas by using a capacitance manometer. Change of the gauge sensitivity due to the magnetic field of GAMMA 10/PDX was also evaluated. The typical gas pressure measured in detached plasma experiments was 0.1-10 Pa. The degree of plasma detachment determined from the reduction of heat flux was enhanced as the gas pressure increases. Rapid increase of the gas pressure under the plasma flow was also observed.

    The author describes his first in 1958 at the unification of electromagnetic and weak interactions and his prediction in the same paper of the neutral Z 0 boson which would be the intermediate quantum exchanged in an eventual electron-neutron weak interaction (as muonic neutrinos were not known at that time). In annex he transcribes copies of letters from Steven Weinberg, Abdus Salam and Bruno Pontecorvo and comments by C.N. Yang and J. Tiomno. (author)

    The authors present the results of a search for standard model Higgs boson production with decay to WW*, identified through the leptonic final states e{sup +}e{sup -} {bar {nu}}{nu}, e{sup {+-}}{mu}{sup {-+}} {bar {nu}}{nu} and {mu}{sup +} {mu}{sup -} {bar {nu}}{nu}. This search uses 360 pb{sup -1} of data collected from p{bar p} collisions at {radical}s = 1.96 TeV by the upgraded Collider Detector at Fermilab (CDF II). They observe no signal excess and set 95% confidence level upper limits on the production cross section times branching ratio for the Higgs boson to WW* or any new scalar particle with similar decay products. These upper limits range from 5.5 to 3.2 pb for Higgs boson masses between 120 and 200 GeV/c{sup 2}.

    We present the results of a search for standard model Higgs boson production with decay to WW*, identified through the leptonic final states e+ e- nu nu,+/-mu -/+nu nu and mu+ mu- nu nu. This search uses 360 pb -1 of data collected from pp collisions at square root of s =1.96 TeV by the upgraded Collider Detector at Fermilab (CDF II). We observe no signal excess and set 95% confidence level upper limits on the production cross section times branching ratio for the Higgs boson to WW* or any new scalar particle with similar decay products. These upper limits range from 5.5 to 3.2 pb for Higgs boson masses between 120 and 200 GeV/c2.

  9. Quantum fields in disequilibrium: Neutral scalar bosons with long-range, inhomogeneous perturbations

    Using Schwinger's quantum action principle, dispersion relations are obtained for neutral scalar mesons interacitng with bilocal sources. These relations are used as the basis of a method for representing the effect of interactions in the Gaussian approximation to field theory, and it is argued that a marked inhomogeneity, in space-time dependence of the sources, forces a discrete spectrum on the field. The development of such a system exhibits features commonly associated with chaos and self-organization (localization by domain or cell formation). The Green functions play the role of an iterative map in phase space. Stable systems reside at the fixed points of the map. The present work can be applied to self-interacting theories by choosing suitable properties for the sources. Rapid transport leads to a second-order phase transition and anomalous dispersion. Finally, it is shown that there is a compact representation of the nonequilibrium dynamics in terms of generalized chemical potentials, or equivalently as a pseudogauge theory, with an imaginary charge. This analogy shows, more clearly, how dissipation and entropy production are related to the source picture and transform a flip-flop like behavior between two reservoirs into the Landau problem in a constant ``magnetic field.'' A summary of conventions and formalism is provided as a basis for future work.

  10. Studies of b-associated production and muonic decays of neutral Higgs bosons at the ATLAS experiment within the Minimal Supersymmetric Standard Model

    This thesis presents a Monte Carlo study of neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) decaying into muons at the ATLAS experiment at the CERN Large Hadron Collider. Signal and background processes are simulated using novel Monte Carlo generators that incorporate parts of higher order corrections and are expected to give a more accurate prediction than previous programs. The SHERPA Monte Carlo generator is validated for its use in the analysis and compared to results obtained with other programs. Where possible, the Monte Carlo event samples are normalized to higher order calculations. To increase the available Monte Carlo statistics, this study is based on the ATLAS fast detector simulation ATLFAST. Differences between ATLFAST and the detailed detector simulation of ATLAS are examined, and, where possible, correction procedures are devised. A cut based analysis is performed assuming an integrated luminosity of 30 fb{sup -1}, and optimized with respect to the discovery potential for MSSM Higgs bosons. The systematic uncertainties of the event selection and the Monte Carlo predictions are estimated. A method that can be used to estimate the background from data is presented and evaluated. Last, the discovery potential of the ATLAS experiment in the CP conserving benchmark scenarios of the MSSM is evaluated. One or more of the neutral Higgs bosons of the MSSM can be discovered in the muonic decay mode using 30 fb{sup -1} of data for low masses of the pseudoscalar boson A{sup 0}, if the model parameter tan {beta} is at least 20. For higher masses of the A{sup 0}, tan {beta} would need to be significantly higher to ensure a discovery in the studied decay channel. The sensitivity of ATLAS to MSSM Higgs bosons is multiple times larger than the one of previous and currently running experiments. (orig.)

    The data taken by DELPHI at centre-of-mass energies between 189 and 209 GeV are used to place limits on the CP-conserving trilinear gauge boson couplings Delta_g1z, lambda_gamma and Delta_kappag associated to W+W- and single W production at LEP2. Using data from the jjlv, jjjj, jjX and lX final states, where j, l and X represent a jet, a lepton and missing four-momentum, respectively, the following limits are set on the couplings when one parameter is allowed to vary and the others are set to their Standard Model values of zero: Delta_g1z = -0.025^{+0.033}_{-0.030}, lambda_gamma = 0.002^{+0.035}_{-0.035} and Delta_kappag = 0.024^{+0.077}_{-0.081} . Results are also presented when two or three parameters are allowed to vary. All observations are consistent with the predictions of the Standard Model and supersede the previous results on these gauge coupling parameters published by DELPHI.

  12. Higgs bosons and sleptons in an alternative left-right model

    International Nuclear Information System (INIS)

    Roszkowski, L.

    1990-01-01

    The phenomenological structure of the combined Higgs-boson--slepton sector of the alternative left-right-supersymmetric model introduced by Ma is explored. Constraints upon and relations between Higgs-boson and slepton masses are derived and a tightly constrained mass spectrum is found. In general, one neutral Higgs boson is never heavier than 98 GeV, one neutral Higgs boson is always nearly degenerate in mass with the extra neutral gauge boson Z 2 0 , and the charged Higgs boson can in principle be as light as 22 GeV. Further constraints require large ratios of Higgs vacuum expectation values, strongly favor the W R mass above ∼423 GeV, predict one Higgs-boson mass to be always very close to 98 GeV, and masses of the other Higgs bosons and the sleptons to be bounded from above and preferably not much above the Z mass. In addition, the possibility of detecting light Higgs bosons at CERN LEP and the SLAC Linear Collider is briefly discussed

    In 1961 Sheldon Lee Glashow, while working on electroweak unification gauge theory, developed a model in which he introduced a massive neutral intermediate vector boson, call Z [1], [2], [3]. By 1967 Steven Weinberg and Abdus Salam had independently solved the theoretical problems with this model and developed their own self-consistent theory. In this thesis the Z gauge boson production rate at CDF as a function of the Z transverse momentum is studied in the dimuon channel.

    A search for a heavy gauge boson W' has been conducted by the CMS experiment at the LHC in the decay channel with an electron and large transverse energy imbalance, using proton-proton collision data corresponding to an integrated luminosity of 36 inverse picobarns. No excess above standard model expectations is seen in the transverse mass distribution of the electron-(missing E_T) system. Assuming standard-model-like couplings and decay branching fractions, a W' boson with a mass less than 1.36 TeV/$c^2$ is excluded at 95% confidence level.

    A search is presented for additional neutral Higgs bosons in the di-$\\tau$ final state in pp collisions at the LHC. The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), on the data collected with the CMS detector in 2016 at a center-of-mass energy of $13~\\mathrm{TeV}$, corresponding to an integrated luminosity of $35.9~\\mathrm{fb}^{-1}$. To enhance the sensitivity to neutral MSSM Higgs bosons the search includes the case where the Higgs boson is produced in association with b quarks. No significant deviation above the expected background is observed. Model-independent limits are set on the product of the cross section and branching fraction for the production via gluon-fusion or in association with b quarks. These limits range from $18~\\mathrm{pb}$ (at $90~\\mathrm{GeV}$) to $3.5\\times 10^{-3}~\\mathrm{pb}$ (at $3.2~\\mathrm{TeV}$) for gluon-fusion and from $15~\\mathrm{pb}$ (at $90~\\mathrm{GeV}$) to $2.5\\times 10^{-3}~\\mathrm{pb}$ (at $3.2~\\mathrm{TeV}$) fo...

    A search is presented for additional neutral Higgs bosons in the $\\tau\\tau$ final state in proton-proton collisions at the LHC. The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), using the data collected with the CMS detector in 2016 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. To enhance the sensitivity to neutral MSSM Higgs bosons, the search includes production of the Higgs boson in association with b quarks. No significant deviation above the expected background is observed. Model-independent limits at 95% confidence level (CL) are set on the product of the branching fraction for the decay into $\\tau$ leptons and the cross section for the production via gluon fusion or in association with b quarks. These limits range from 18 pb at 90 GeV to 3.5 fb at 3.2 TeV for gluon fusion and from 15 pb (at 90 GeV) to 2.5 fb (at 3.2 TeV) for production in association with b quarks. In the ${m_{\\text{h}}^{\\tex...

    We present a new limit on the production of a light dark-force mediator with the KLOE detector at DAΦNE. This boson, called U, has been searched for in the decay ϕ→ηU, U→e + e − , analyzing the decay η→π 0 π 0 π 0 in a data sample of 1.7 fb −1 . No structures are observed in the e + e − invariant mass distribution over the background. This search is combined with a previous result obtained from the decay η→π + π − π 0 , increasing the sensitivity. We set an upper limit at 90% C.L. on the ratio between the U boson coupling constant and the fine structure constant of α ′ /α<1.7×10 −5 for 30

    A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton--proton collisions at a centre-of-mass energy of $8 TeV$ collected with the ATLAS detector at the Large Hadron Collider. The samples used for this search were collected in 2012 and correspond to integrated luminosities in the range 19.5 - 20.3 fb$^{-1}$. The MSSM Higgs bosons are searched for in the $\\tau\\tau$ final state. No significant excess over the expected background is observed, and exclusion limits are derived for the production cross section times branching fraction of a scalar particle as a function of its mass. The results are also interpreted in the MSSM parameter space for various benchmark scenarios.

    The e + e - -collider facilities at LEP II, with the cm energy √S in the range 100-170 GeV may be able to detect ''light'' Higgs bosons, assuming a high luminosity. In this paper, we have calculated production cross-sections of a light Higgs boson H 0 in association with the neutral gauge boson Z 0 , for varying ranges of the cm energy expected to be available to LEP II and VLEEP (Novosibirsk) and for various values of the light Higgs mass. It is found out that production cross-sections are sizeable in comparison with those for the very massive Higgs bosons in proton-anti(proton) super-colliders, Tevatron, Spp-barS and SSC, respectively. The implication of this feature is pointed out. Further, prospects for light Higgs production in association with the charged gauge boson, W - in ultra energetic neutrino beams are examined.

    The model with the SU(2) L x SU(2) R x U(1) B-L gauge group, containing one bidoublet and two triplets in the Higgs sector, is considered. The link between the constants determining the physical Higgs boson interactions and the neutrino oscillation parameters is found. It is shown that the observation of the ultrahigh-energy neutrinos with the help of the processes e - ν e →W - Z, e - ν e →μ - ν μ , gives us information on the singly charged Higgs bosons. The processes of the doubly charged Higgs boson production, e - μ - →Δ (--) 1 γ, e - μ - →Δ (--) 1 Z, are investigated. From the point of view of detecting the neutral Higgs bosons the process of the electron-muon recharge e - μ + →e + μ - is studied. (orig.)

    A search for neutral Higgs bosons predicted in the minimal supersymmetric standard model (MSSM) for μ+μ- decay channels is presented. The analysis uses data collected by the CMS experiment at the LHC in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, corresponding to integrated luminosities of 5.1 and 19.3 fb-1, respectively. The search is sensitive to Higgs bosons produced either through the gluon fusion process or in association with a b b ‾ quark pair. No statistically significant excess is observed in the μ+μ- mass spectrum. Results are interpreted in the framework of several benchmark scenarios, and the data are used to set an upper limit on the MSSM parameter tan ⁡ β as a function of the mass of the pseudoscalar A boson in the range from 115 to 300 GeV. Model independent upper limits are given for the product of the cross section and branching fraction for gluon fusion and b quark associated production at √{ s} = 8 TeV. They are the most stringent limits obtained to date in this channel.

    The first-quantized theory of open bosonic strings in a background isotropic electromagnetic field is constructed. Two types of the open strings, neutral and charged, are considered. The modified light-like gauge conditions are introduced, general solutions of the equations of motion are obtained and the consistency of the theory does not entails the constraints on the strength of an external isotropic electromagnetic field. 11 refs

    2018-01-01

    We propose a minimally extended gauge symmetry model with U (1 )R , where only the right-handed fermions have nonzero charges in the fermion sector. To achieve both anomaly cancellations and minimality, three right-handed neutrinos are naturally required, and the standard model Higgs has to have nonzero charge under this symmetry. Then we find that its breaking scale(Λ ) is restricted by precise measurement of neutral gauge boson in the standard model; therefore, O (10 ) TeV ≲Λ . We also discuss its testability of the new gauge boson and discrimination of U (1 )R model from U (1 )B-L one at collider physics such as LHC and ILC.

    A search for a heavy MSSM Higgs boson is performed in the φ→ττ→eμ decay channel, using data corresponding to an integrated luminosity of 19.7 fb -1 at a p-p center of mass energy of 8TeV, collected by the CMS experiment at the Large Hadron Collider. The search is optimized for Higgs boson masses between 300 and 1000 GeV and makes the use of Boosted Decision Trees for an improved selection of signal events. The results are consistent with the predictions of the Standard Model.

    A search is performed for a new resonance decaying into a lighter resonance and a Z boson. Two channels are studied, targeting the decay of the lighter resonance into either a pair of oppositely charged τ leptons or a b b ‾ pair. The Z boson is identified via its decays to electrons or muons. The search exploits data collected by the CMS experiment at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.8 fb-1. No significant deviations are observed from the standard model expectation and limits are set on production cross sections and parameters of two-Higgs-doublet models.

  8. Distinguishing the Higgs Boson from the Dilaton at the Large Hadron Collider

    It is likely that the LHC will observe a color- and charge-neutral scalar whose decays are consistent with those of the standard model (SM) Higgs boson. The Higgs interpretation of such a discovery is not the only possibility. For example, electroweak symmetry breaking could be triggered by a spontaneously broken, nearly conformal sector. The spectrum of states at the electroweak scale would then contain a narrow scalar resonance, the pseudo-Goldstone boson of conformal symmetry breaking, with Higgs-boson-like properties. If the conformal sector is strongly coupled, this pseudodilaton may be the only new state accessible at high energy colliders. We discuss the prospects for distinguishing this mode from a minimal Higgs boson at the LHC and ILC. The main discriminants between the two scenarios are (i) cubic self-interactions and (ii) a potential enhancement of couplings to massless SM gauge bosons

    The top quark produced through the electroweak channel provides a direct measurement of the Vtb element in the CKM matrix which can be viewed as a transition rate of a top quark to a bottom quark. This production channel of top quark is also sensitive to different theories beyond the Standard Model such as heavy charged gauged bosons termed W'. This thesis measures the cross section of the electroweak produced top quark using a technique based on using the matrix elements of the processes under consideration. The technique is applied to 2.3 fb-1 of data from the D0 detector. From a comparison of the matrix element discriminants between data and the signal and background model using Bayesian statistics, we measure the cross section of the top quark produced through the electroweak mechanism σ(p$\\bar{p}$ → tb + X, tqb + X) = 4.30-1.20+0.98 pb. The measured result corresponds to a 4.9σ Gaussian-equivalent significance. By combining this analysis with other analyses based on the Bayesian Neural Network (BNN) and Boosted Decision Tree (BDT) method, the measured cross section is 3.94 ± 0.88 pb with a significance of 5.0σ, resulting in the discovery of electroweak produced top quarks. Using this measured cross section and constraining |Vtb| < 1, the 95% confidence level (C.L.) lower limit is |Vtb| > 0.78. Additionally, a search is made for the production of W' using the same samples from the electroweak produced top quark. An analysis based on the BDT method is used to separate the signal from expected backgrounds. No significant excess is found and 95% C.L. upper limits on the production cross section are set for W' with masses within 600-950 GeV. For four general models of W{prime} boson production using decay channel W' → t$\\bar{p}$, the lower mass limits are the following: M(W'L with SM couplings) > 840 GeV; M(W'R) > 880 GeV or 890 GeV if the

    The past few years have seen fascinating progress in the creation and utilization of synthetic gauge fields for charge-neutral ultracold atoms. Whereas the synthesis of gauge fields in itself is readily interesting, it is more exciting to explore the new era that will be brought by the interplay between synthetic gauge fields and many other degrees of freedom of highly tunable ultracold atoms. This topical review surveys recent developments in using synthetic gauge fields to manipulate novel quantum phenomena that are not easy to access in other systems. We first summarize current experimental methods of creating synthetic gauge fields, including the use of Raman schemes, shaken lattices, and Raman-dressed lattices. We then discuss how synthetic gauge fields bring new physics to non-interacting systems, including degenerate single-particle ground states, quartic dispersions, topological band structures in lattices, and synthetic dimensions. As for interacting systems, we focus on novel quantum many-body states and quantum macroscopic phenomena induced by interactions in the presence of unconventional single-particle dispersions. For bosons, we discuss how a quartic dispersion leads to non-condensed bosonic states at low temperatures and at the ground state. For fermions, we discuss chiral superfluids in the presence of attractive s-wave interaction, where high partial-wave interactions are not required. Finally, we discuss the challenges in current experiments, and conclude with an outlook for what new exciting developments synthetic gauge fields may bring us in the near future.

    2015-01-01

    Resonant production of two electroweak gauge bosons (WW, WZ, ZZ) is a smoking gun signature for physics beyond the Standard Model, and various possibilities resulting in such signatures have been proposed, e.g. Extended Gauge Models with heavy charged/neutral bosons (W', Z'), bulk Randall-Sundum excitation of the graviton (G*) in extra dimensions, and strongly coupled theories such as Technicolor (e.g. techni-rho meson). Searches for such high-mass resonances can obtain a significant sensitivity gain by exploiting techniques to identify the hadronic decay of boosted W and Z bosons. This talk summarizes ATLAS searches for diboson resonances in final states including hadronic jets with boosted W/Z boson tagging at LHC Run 1.

    This paper presents a study of the production of WW or WZ boson pairs, with one W boson decaying to eν or μ ν and one W or Z boson decaying hadronically. The analysis uses 20.2 fb ^{-1} of √{s} =8 {TeV} pp collision data, collected by the ATLAS detector at the Large Hadron Collider. Cross-sections for WW / WZ production are measured in high-pT fiducial regions defined close to the experimental event selection. The cross-section is measured for the case where the hadronically decaying boson is reconstructed as two resolved jets, and the case where it is reconstructed as a single jet. The transverse momentum distribution of the hadronically decaying boson is used to search for new physics. Observations are consistent with the Standard Model predictions, and 95% confidence intervals are calculated for parameters describing anomalous triple gauge-boson couplings.

    A search for the production of neutral Higgs bosons Φ decaying into τ+τ- final states in pp¯ collisions at a center-of-mass energy of 1.96 TeV is presented. The data, corresponding to an integrated luminosity of approximately 325pb-1, were collected by the D0 experiment at the Fermilab Tevatron Collider. Since no excess compared to the expectation from standard model processes is found, limits on the production cross section times branching ratio are set. The results are combined with those obtained from the D0 search for Φb(b¯)→bb¯b(b¯) and are interpreted in the minimal supersymmetric standard model.

    This thesis presents the results of a search for neutral MSSM Higgs bosons decaying to ττ with 5.9 fb.–1 of data. The analysis requires at least one of the taus to decay leptonically, and explores three detection modes in two channels: τeτ μ, τeτhad, and τμτhad, where the index denotes the type of tau decay. In all modes we explore the tagged and untagged channel. No signal is observed limits were set on σ( p$\\bar{p}$ → Φ + X) × BR(Φ → ττ) as a function of Higgs mass. The results are also interpreted as exclusions of parameter space in the tanβ vs mA plane for several benchmark scenarios.

    The ATLAS detector at the LHC is used to search for high-mass states, such as heavy charged gauge bosons (W'), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 1.04 fb-1. No excess beyond Standard Model expectations is observed. A W' with Sequential Standard Model couplings is excluded at the 95% confidence level for masses up to 2.15 TeV.
