    The authors present the first measurement of the top quark mass using simultaneously data from two decay channels. They use a data sample of √s = 1.96 TeV collisions with integrated luminosity of 1.9 fb-1 collected by the CDF II detector. They select dilepton and lepton + jets channel decays of t$\\bar{t}$ pairs and reconstruct two observables in each topology. They use non-parametric techniques to derive probability density functions from simulated signal and background samples. The observables are the reconstructed top quark mass and the scalar sum of transverse energy of the event in the dilepton topology and the reconstructed top quark mass and the invariant mass of jets from the W boson decay in lepton + jets channel. They perform a simultaneous fit for the top quark mass and the jet energy scale which is constrained in situ by the hadronic W boson resonance from the lepton + jets channel. Using 144 dilepton candidate events and 332 lepton + jets candidate events they measure: Mtop = 171.9 ± 1.7 (stat. + JES) ± 1.1 (other sys.) GeV/c2 = 171.9 ± 2.0 GeV/c2. The measurement features a robust treatment of the systematic uncertainties, correlated between the two channels and develops techniques for a future top quark mass measurement simultaneously in all decay channels. Measurements of the W boson mass and the top quark mass provide a constraint on the mass of the yet unobserved Higgs boson. The Higgs boson mass implied by measurement presented here is higher than Higgs boson mass implied by previously published, most precise CDF measurements of the top quark mass in lepton + jets and dilepton channels separately.

    The top quark, the most recently discovered quark, is the most massive known fundamental fermion. Precision measurements of its mass, a free parameter in the Standard Model of particle physics, can be used to constrain the mass of the Higgs Boson. In addition, deviations in the mass as measured in different channels can provide possible evidence for new physics. We describe a measurement of the top quark mass in the decay channel with two charged leptons, known as the dilepton channel, using data collected by the CDF II detector from p$\\bar{p}$ collisions with √s = 1.96 TeV at the Fermilab Tevatron. The likelihood in top mass is calculated for each event by convolving the leading order matrix element describing q$\\bar{q}$ → t$\\bar{t}$ → bℓv$\\bar{b}$ℓ'vℓ' with detector resolution functions. The presence of background events in the data sample is modeled using similar calculations involving the matrix elements for major background processes. In a data sample with integrated luminosity of 1.0 fb-1, we observe 78 candidate events and measure Mt = 164.5 ± 3.9(stat.) ± 3.9(syst.) GeV/c2, the most precise measurement of the top quark mass in this channel to date.

    The top quark pair production and decay into leptons with at least one being a τ lepton is studied in the framework of the CDF experiment at the Tevatron proton antiproton collider at Fermilab (USA). The selection requires an electron or a muon produced either by the τ lepton decay or by a W decay. The analysis uses the complete Run II data set i.e. 9.0 fb-1, selected by one trigger based on a low transverse momentum electron or muon plus one isolated charged track. The top quark pair production cross section at 1.96 TeV is measured at 8.2 ± 1.7+1.2-1.1 ± 0.5 pb, and the top branching ratio into τ lepton is measured at 0.120 ± 0.027+0.022 -0.019 ± 0.007 with statistical, systematics and luminosity uncertainties. These are up to date the most accurate results in this top decay channel and are in good agreement with the results obtained using other decay channels of the top at the Tevatron. The branching ratio is also measured separating the single lepton from the two leptons events with a log likelihood method. This is the first time these two signatures are separately identified. With a fit to data along the log-likelihood variable an alternative measurement of the branching ratio is made: 0.098 ± 0.022(stat:) ± 0.014(syst:); it is in good agreement with the expectations of the Standard Model (with lepton universality) within the experimental uncertainties. The branching ratio is constrained to be less than 0.159 at 95% con dence level. This limit translates into a limit of a top branching ratio into a potential charged Higgs boson.

    We investigate the CP violating asymmetry, the forward-backward asymmetry and the CP violating asymmetry in the forward-backward asymmetry for the radiative dileptonic B-meson decays B-d --> gammal(+)l(-) for the f = e, mu, tau channels. It is observed that these asymmetries are quite sizable and B-

    This dissertation describes a search for the Standard Model Higgs boson produced in association with the Z boson via Higgs-strahlung at the CDF II detector at the Tevatron. At a Higgs boson mass between 100 GeV/c{sup 2} and 135 GeV/c{sup 2}, the primary Higgs decay mode is to a pair of b quarks. The associated Z boson can decay to a pair of electrons or muons, allowing detection of a final event signature of two visible leptons and two b quarks. This final state allows reduction of large QCD backgrounds compared to a hadronic Z boson decay, leading to a more sensitive search. To increase sensitivity, standard model matrix element probabilities for ZH signal and the dominant backgrounds are used as components to a likelihood fit in signal fraction. In 2.7 fb{sup -1} of CDF II data, we see no evidence of production of a Higgs boson with a mass between 100 GeV c{sup 2} and 150 GeV/c{sup 2}. Using the Feldman-Cousins technique to set a limit, at 95% coverage and a Higgs boson mass of 115 GeV/c{sup 2}, the median expected limit was 12.1 x {sigma}{sub SM} and a limit of 8.2 x {sigma}{sub SM} was observed, where {sigma}{sub SM} is the NNLO theoretical cross section of p{bar p} {yields}ZH {yields} l +l -b{bar b} at {radical}s=1.96 TeV . Cross section limits are computed at a range of Higgs boson mass values between 100 GeV/c {sup 2} and 150 GeV/c{sup 2}.

    The $t\\bar{t}$ charge asymmetry in proton-proton collisions at $\\sqrt{s}$=7 TeV is measured using the dilepton decay channel ($ee, e\\mu,$ or $\\mu\\mu$). The data correspond to a total integrated luminosity of 5.0 inverse-femtobarns, collected by the CMS experiment at the LHC. The top-antitop and lepton charge asymmetries, defined as the differences in absolute values of the rapidities between the reconstructed top quarks and antiquarks and of the pseudorapidities between the positive and negative leptons, respectively, are measured to be $A_C$ = -0.010 +/- 0.017 (stat.) +/- 0.008 (syst.) and $A_C^{lep}$ = 0.009 +/- 0.010 (stat.) +/- 0.006 (syst.). The lepton charge asymmetry is also measured as a function of the invariant mass, rapidity, and transverse momentum of the top-antitop system. All measurements are consistent with the expectations of the standard model.

    Jet multiplicity distributions in top quark pair ([Formula: see text]) events are measured in pp collisions at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC using a data set corresponding to an integrated luminosity of 19.7[Formula: see text]. The measurement is performed in the dilepton decay channels ([Formula: see text], [Formula: see text], and [Formula: see text]). The absolute and normalized differential cross sections for [Formula: see text] production are measured as a function of the jet multiplicity in the event for different jet transverse momentum thresholds and the kinematic properties of the leading additional jets. The differential [Formula: see text] and [Formula: see text] cross sections are presented for the first time as a function of the kinematic properties of the leading additional [Formula: see text] jets. Furthermore, the fraction of events without additional jets above a threshold is measured as a function of the transverse momenta of the leading additional jets and the scalar sum of the transverse momenta of all additional jets. The data are compared and found to be consistent with predictions from several perturbative quantum chromodynamics event generators and a next-to-leading order calculation.

    We report on a measurement of the top-quark mass ($\\mathrm{M}_{\\mathrm{t}}$) in the dileptonic $\\mathrm{t}\\overline{\\mathrm{t}}$ decay channel using events selected from a data sample corresponding to an integrated luminosity of $19.7 \\pm 0.5 \\text{ fb}^{-1}$. The events were recorded by the CMS detector at the LHC in proton-proton collisions at $\\sqrt{s} = 8$ TeV. The analysis is based on three observables whose distribution shapes are sensitive to the value of $\\mathrm{M}_{\\mathrm{t}}$. The $\\mathrm{M}_{\\mathrm{b}\\ell}$ invariant mass and $\\mathrm{M}_{\\mathrm{T}2}^{\\mathrm{bb}}$ `stransverse mass' observables are employed in a simultaneous fit to determine the value of $\\mathrm{M}_{\\mathrm{t}}$ and an overall jet energy scale factor (JSF). In a complementary approach, the $\\mathrm{M}_{\\mathrm{T}2}$-Assisted On-Shell reconstruction technique is used to construct an $\\mathrm{M}_{\\mathrm{b}\\ell\

  9. Semi- and Dileptonic Top Pair Decays at the ATLAS Experiment

    Mameghani, Raphael

    The Large Hadron Collider, starting in 2008, will be a "top factory" as top-antitop pairs will be produced with a cross section of about 830 pb at an instantaneous luminosity of 10^33 cm^-2 s^-1 during the first year. With about 30% probability top pairs decay semileptonically into a final state with four jets, lepton (electron or muon) and respective neutrino. For another 5% of the top pair events a dileptonic decay is expected. Here the final state signature is composed of two jets, two leptons and two neutrinos. In this thesis the precision for a top pair cross section measurement at the ATLAS experiment in the semileptonic and dileptonic channels with cut based analyses, applicable to the first data, was estimated. The analysis of the semileptonic decay focused especially on the study of background from QCD events either with leptons from semileptonic hadron decays or from hadrons falsely identified as electrons by the calorimeter. For the first 10 fb^-1 and assuming a fake electron probability of 10^-3 a...

    The Large Hadron Collider, starting in 2008, will be a 'top factory' as top-antitop (t anti t) pairs will be produced with a cross section of about 830 pb at an instantaneous luminosity of 10{sup 33}cm{sup -2}s{sup -1} during the first year. With about 30% probability top pairs decay semileptonically into a final state with four jets, lepton (electron or muon) and respective neutrino. For another 5% of the t anti t events a dileptonic decay is expected. Here the final state signature is composed of two jets, two leptons and two neutrinos. In this thesis the precision for a t anti t cross section measurement at the ATLAS experiment in the semileptonic and dileptonic channels with cut based analyses, applicable to the first data, was estimated. The analysis of the semileptonic decay focused especially on the study of background from QCD events either with leptons from semileptonic hadron decays or from hadrons falsely identified as electrons by the calorimeter. For the first 10 fb{sup -1} and assuming a fake electron probability of 10{sup -3} a precision for the cross section times the branching ratio of {delta}({sigma}{sub t} {sub anti} {sub t}.B(t anti t{yields}bq anti q' anti bl anti {nu}))={+-}0.5(stat){+-}30.4(syst){+-}24.0(lumi) pb has been estimated, corresponding to a relative precision of 16% for the theoretically predicted cross section times branching ratio of about 240 pb. The analysis in the dileptonic channel achieves a precision of {delta}({sigma}{sub t} {sub anti} {sub t}.B(t anti t{yields}b anti l{nu} anti bl anti {nu}))={+-}0.2(stat){+-}2.5(syst){+-}2.6(lumi) pb which translates into a relative error of 10% for the cross section times branching ratio of around 38 pb. The errors for both the semileptonic and the dileptonic channel are expected to improve as progress is made on the luminosity determination and the knowledge of the backgrounds from comparisons with measured data.

    We present measurements of the t ̄ t production cross section obtained using the ATLAS detector at the LHC with pp collisions at √ s = 7 TeV in dilepton final states, from a data sample of L =698 pb − 1 taken in 2011. For dilepton pair selection we have used a ‘Lepton+Tra ck’ approach, where selection requirements on one lepton leg are reduced to a requirement of only a high qu ality Inner Detector track. This proce- dure, while allowing more background in the selected sample , enhances the sensitivity to τ -leptonic decays of the W ± and increases the t ̄ t acceptance by 20% over the conventional dilepton analysis ( where each lepton is identified as an electron or muon). Two modes of the l +track analysis were studied: the inclu- sive and the exclusive mode. The measured t ̄ t cross sections in the inclusive e TL and TL channels are 182 . 9 ± 9 . 3 (stat . ) +21 . 9 − 16 . 7 (syst . ) +8 . 2 − 7 . 3 (lum . ) pb and 171 . 0 ± 8 . 5 (stat . ) +20 . 6 − 17 . 5 (syst . ) +7 . 8 − 7 . 0 (l...

  12. Search for long-lived particles decaying to final states that include dileptons

    The experimental signature is a distinctive topology consisting of a pair of charged leptons originating from a displaced secondary vertex. Events were collected by the CMS detector at the LHC during pp collisions at $\\sqrt{s} = 8$~TeV, and selected from data samples corresponding to 19.6 (20.5)~fb$^{-1}$ of integrated luminosity in the electron (muon) channel. No significant excess is observed above standard model expectations. Upper limits are set on such a signal, as a function of the long-lived particle lifetime, in the context of two specific models. In the first, Higgs bosons decay to a pair of long-lived neutral particles that each subsequently decay to dileptons. In the second, events contain a pair of squarks that each decay to a long-lived neutralinos, which then each decay to dileptons and a neutrino.

    2016-01-01

    A short summary of a NLO QCD calculation for the top-quark pair production with a jet in the dilepton decay channel is presented. The calculation takes into account all double, single, non-resonant and interference contributions. Thus, NLO QCD corrections are computed for the process pp -> e+ ve mu- vm~ b b~ j + X. This calculation provides the first complete description, which overcomes the narrow width approximation for ttj process in the dilepton decay channel. Results for the total cross section and differential distributions for the LHC at sqrt(s) = 8 TeV are shown.

    A measurement of the top quark mass (M[t]) in the dileptonic ttbar decay channel is performed using data from proton-proton collisions at a center-of-mass energy of 8 TeV. The data was recorded by the CMS experiment at the LHC and corresponding to an integrated luminosity of 19.7 +/- 0.5 inverse femtobarns. Events are selected with two oppositely charged leptons (l = e, mu) and two jets identified as originating from b quarks. The analysis is based on three kinematic observables whose distributions are sensitive to the value of M[t]. An invariant mass observable, M[b l], and a `stransverse mass' observable, M[T2], are employed in a simultaneous fit to determine the value of M[t] and an overall jet energy scale factor (JSF). A complementary approach is used to construct an invariant mass observable, M[b l nu], that is combined with M[T2] to measure M[t]. The shapes of the observables, along with their evolutions in M[t] and JSF, are modeled by a nonparametric Gaussian process regression technique. The sensitivity of the observables to the value of M[t] is investigated using a Fisher information density method. The top quark mass is measured to be 172.22 +/- 0.18 (stat) +0.89/-0.93 (syst) GeV.

The analysis is based on three kinematic observables whose distributions are sensitive to the value of $M_{\\mathrm{ t }}$. An invariant mass observable, $M_{\\mathrm{ b }\\ell}$, and a 'stransverse mass' observable, $M_{\\mathrm{T}2}$, are employed in a simultaneous fit to determine the value of $M_{\\mathrm{ t }}$ and an overall jet energy scale factor (JSF). A complementary approach is used to construct an invariant mass observable, $M_{\\mathrm{ b }\\ell\

    Jet multiplicity distributions in top quark pair ($ \\mathrm{ t \\bar{t} } $) events are measured in pp collisions at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC using a data set corresponding to an integrated luminosity of 19.7 fb$^{-1}$. The measurement is performed in the dilepton decay channels ($ \\mathrm{ e^{+} e^{-} }$, $\\mu^{+} \\mu^{-} $, and $\\mathrm{ e^{\\pm} } \\mu^{\\mp} $). The absolute and normalized differential cross sections for $ \\mathrm{ t \\bar{t} } $ production are measured as a function of the jet multiplicity in the event for different jet transverse momentum thresholds and the kinematic properties of the leading additional jets. The differential $ \\mathrm{ t \\bar{t} b} $ and $ \\mathrm{ t \\bar{t} b \\bar{b} } $ cross sections are presented for the first time as a function of the kinematic properties of the leading additional b jets. Furthermore, the fraction of events without additional jets above a threshold is measured as a function of the transverse momenta of the leadi...

    After commissioning of the Large Hadron Collider at the European nuclear research centre CERN, the CMS detector had recorded data with an integrated luminosity of 1.1 fb{sup -1} at a centre-of-mass energy of 7 TeV already in Summer 2011. With this, it was possible for the first time to accurately measure properties of the top quark with high statistics. The work presented here focuses on the measurement of normalised differential top quark pair production cross sections in the decay channel into final states with two oppositely charged leptons. The measurement is presented in dependence of kinematic properties of the top quarks, the top quark pair, the leptons, and the lepton pair. The distributions allow for detailed testing of perturbative quantum chromodynamics and thus the Standard Model of particle physics. Many of the distributions are also sensitive to processes beyond the Standard Model. In this work, comparisons of the measured cross sections with three different predictions are shown. The result is that the predictions are in accordance with the measurement, only a slight deviation of the prediction from the measurement is visible in few distributions. In the outlook it is shown that a fourth, more accurately calculated prediction for the measurement of the top quark transverse momentum normalised differential cross section is in even better agreement with the data. Thus it can be concluded that the Standard Model was tested successfully and that no hints for new physics are found.

    We measure the top quark mass (m(t)) in p ̄p collisions at a center of mass energy √s = 1.96 TeV using dilepton t ̄t→W(+)bW(-) ̄b→ℓ(+)ν(ℓ)bℓ(-) ̄ν(ℓ) ̄b events, where ℓ denotes an electron, a muon, or a tau that decays leptonically. The data correspond to an integrated luminosity of 5.4 fb(-1) collected with the D0 detector at the Fermilab Tevatron Collider. We obtain m(t)=174.0±1.8(stat)±2.4(syst) GeV, which is in agreement with the current world average m(t)=173.3±1.1 GeV. This is currently the most precise measurement of m(t) in the dilepton channel.

    We present a measurement of the top quark mass in the dilepton channel based on approximately 370/pb of data collected by the D0 experiment during Run II of the Fermilab Tevatron collider. We employ two different methods to extract the top quark mass. We show that both methods yield consistent results using ensemble tests of events generated with the D0 Monte Carlo simulation. We combine the results from the two methods to obtain a top quark mass m_t = 178.1 +/- 8.2 GeV. The statistical uncertainty is 6.7 GeV and the systematic uncertainty is 4.8 GeV.

    In this thesis, the production of Z{sup 0} boson and top-quark pairs is studied. In particular, the decays into two leptons are analyzed. The data recorded by the CMS experiment at the LHC in 2011 is used, corresponding to an integrated luminosity of 1.14 fb{sup -1}. The candidates are selected by requiring two isolated opposite-sign lepton candidates. The t anti t and Z{sup 0} signal are disentangled by separating the events into two different regions of the invariant mass of the lepton candidate pair. The selection of the t anti t event candidates also includes the requirement for two jets, missing transverse momentum and at least one jet originating from a b-quark. Data-driven estimates for trigger and isolation efficiencies are determined and the electron energies are re-calibrated using the Z{sup 0} invariant mass peak. The main backgrounds to the t anti t and to the Z{sup 0} events are corrected to or obtained from data, respectively. A Z{sup 0} boson production cross section of {sigma}{sub Z}=31.1{+-}{sub 1.3}{sup 0.9} (syst.){+-}1.4(lumi.) nb is determined, corresponding to the combination of decay channels into different lepton types. A t anti t production cross section using the dileptonic channels of {sigma}{sub t} {sub anti} {sub t,comb}=181.6{+-}3.5(stat.){+-}{sub 12.7}{sup 12.0}(syst.){+-}8.2(lumi.) pb is obtained, corresponding to the combination of the e{sup +}e{sup -}, {mu}{sup +}{mu}{sup -} and e{sup {+-}}{mu}{sup -+} channels. A cross section ratio of t anti t to Z{sup 0} production of {sigma}{sub t} {sub anti} {sub t}/{sigma}{sub Z}=5.52{+-}0.18(stat.){+-}{sub 0.54}{sup 0.48}(syst.).10{sup -3} is measured. This cross section ratio can be used for an alternative determination of the top-pair production cross section, making use of the precise prediction of the Z{sup 0} boson production in the kinematic range of the analysis. The advantage of this method is a cancellation of the luminosity uncertainty. In this way, a value of the top

    Full Text Available There are many extensions to the Standard Model of particle physics which predict the addition of a U(1 symmetry, and/or extra spatial dimensions, which give rise to new high mass resonances such as the Z′ and Randall-Sundrum graviton. The LHC provides a unique opportunity to explore the TeV scale where these phenomena may become apparent, and can be searched for using the precision tracking and high energy resolution calorimetry of the ATLAS detector. This poster presents the search for high mass resonances in the dilepton channel, and was conducted with an integrated luminosity of 1.08/1.21 fb−1 in the dielectron/dimuon channel respectively, at a centre of mass energy √s = 7 TeV.

    The degree of top polarization and strength of $t\\bar{t}$ correlation are dependent on production dynamics, decay mechanism, and choice of the observables. At the LHC, measurement of the top polarization and spin correlations in $t\\bar{t}$ production is possible through various observables related to the angular distribution of decay leptons. A measurement of differential distribution provides a precision test of the standard model of particle physics and probes for deviations, which could be a sign of new physics. In particular, the phase space for the super-symmetric partner of the top quark can be constrained. Results from the Compact Muon Solenoid (CMS) collaboration for top quark polarization and spin correlation in the dileptonic channel are reviewed briefly in this proceeding. The measurements are obtained using 19.5 fb$^{-1}$ of data collected in pp collisions at the center-of-mass energy of 8 TeV.

    We report on dilepton measurements for central Pb on Au collisions at the top CERN SPS energy with the upgraded CERES experiment. The dilepton mass spectrum of 2000 data with improved mass resolution shows an enhancement over the expectation from hadron decays that is well described by a model including a strong broadening of the $\\rho$ spectral function. The measured excess yield excludes the dropping mass scenario. We also report on the $\\phi$ meson measured simultaneously both in the $K^+K^-$ and in the dilepton decay channel for the first time in high energy heavy-ion collisions. An excellent agreement is found between the rapidity densities and the shape of the measured tranverse momentum spectrum. The data rule out a possible enhancement of the $\\phi$ yield in the leptonic over hadronic channel by a factor larger than 1.6 at 95% CL. CERES results are in agreement with NA49 results.

    We present a method for extracting the mass of the top quark from the di-lepton decays of top anti-top quark pairs. In this decay channel two neutrinos remain undetected. Extraction of the mass of the top quark by kinematic reconstruction is not possible because the event is under-constrained. We therefore employ a dynamical likelihood method to solve the problem.

    We present the results of a search for doubly-charged Higgs bosons (H+/-+/-) decaying to dileptons using ~240/pb of ppbar collision data collected by the CDF II experiment at the Fermilab Tevatron. In our search region, given by same-sign dilepton mass m_ll' > 80 GeV/c^2 (100 GeV/c^2 for dielectron channel), we observe no evidence for doubly-charged Higgs production. We set limits on sigma (ppbar --> H++H-- --> l+l+l-l-) as a function of the mass of the doubly-charged Higgs boson and the chirality of its couplings. Assuming exclusive same-sign dilepton decays, we derive lower mass limits on H+/-+/-_L of 133 GeV/c^2, 136 GeV/c^2, and 115 GeV/c^2 in the ee, mu mu, and e mu channels, respectively, and a lower mass limit of 113 GeV/c^2 on H+/-+/-_R in the mu mu channel, all at the 95% confidence level.

    The first dilepton yield measurements from excited nuclear states obtained with a new Positron-Electron Pair Spectroscopic Instrument (PEPSI) are reported. Nuclear states in [sup 28]Si, with an initial excitation energy E[sup *] =50 MeV, were populated via the isospin T=0 reaction [sup 4]He+[sup 24]Mg and the mixed-isospin [sup 3]He+[sup 25]Mg reaction. In both reactions the dilepton (e[sup +]e[sup -]) and photon decay yields were measured concurrently. An excess of counts in the e[sup +]e[sup -] spectrum, over the converted photon yield, is observed in the energy region above 15 MeV. An analyses is discussed whereby the observed excess counts are assumed to represent the isoscalar E0 strength in excited nuclear states. (orig.)

    Differential cross sections of top-quark pair production are measured in the dilepton decay channel with proton-proton collisions at a center-of-mass energy of 13 TeV. The measurement is performed with Run II data using the CMS detector at the Large Hadron Collider.

    We report a measurement of the top quark mass using six candidate events for the process pp¯-->tt¯+X-->l+νbl-ν¯b¯+X, observed in the D0 experiment at the Fermilab pp¯ collider. Using maximum likelihood fits to the dynamics of the decays, we measure a mass for the top quark of mt=168.4+/-12.3(stat)+/-3.6(syst) Gev. We combine this result with our previous measurement in the tt¯-->l+jets channel to obtain mt=172.1+/-7.1 GeV as the best value of the mass of the top quark measured by D0.

  13. Rare dileptonic B0(s) meson decays at LHCb

    CERN Document Server

    Mordà, Alessandro

    The B0(s)→ℓℓ¯B(s)0→ℓℓ¯ decays are generated by Flavor Changing Neutral Currents, hence they can proceed only through loop processes. For this reason, and because of an additional helicity suppression, their branching ratios are predicted to be very small in the Standard Model (SM). Nevertheless their rates can be modified by the appearance of New Physics (NP) particles inside the loops. In SM their rates are predicted with a very small uncertainty, and from the comparison between the measured values and their theoretical prediction hints on the NP realization patterns can be inferred. A part of the original work presented in this thesis has been devoted to the optimization of the Multi Variate Analysis (MVA) classifier for the search of the B0(s)→μ+μ−B(s)0→μ+μ− with the full dataset collected at LHCb during the first run of the LHC (corresponding to an integrated luminosity of ∼3fb−1∼3fb−1).

  14. The Landau pole and Z‧ decays in the 331 dilepton model

    Martínez, R.; Ochoa, F.

    2007-08-01

    We calculate the decay widths and branching ratios of the extra neutral boson Z’ predicted by the 331 dilepton model in the framework of two different particle contents. These calculations are performed taking into account oblique radiative corrections and flavor changing neutral currents (FCNC) under the ansatz of Matsuda as a texture for the quark mass matrices. Contributions of the order of 10-1-10-2 are obtained in the branching ratios, and the partial widths about one order of magnitude bigger in relation with other 331 models are also obtained. A Landau-like pole arises at 3.5 TeV considering the full particle content of the minimal dilepton model (MDM), where the exotic sector is considered as a degenerate spectrum at the 3 TeV scale. The Landau pole problem can be avoided at the TeV scales if a new leptonic content running below the threshold at 3 TeV is implemented as suggested by other authors.

    2017-01-01

    A search for the production of heavy partners of the top quark with charge 5/3 decaying to same-sign dileptons is presented. The data sample was collected at a center of mass energy of $\\sqrt{s} = 13~\\mathrm{TeV}$ by the CMS experiment at the Large Hadron Collider in 2016 and corresponds to an integrated luminosity of $35.9~\\mathrm{fb}^{-1}$. The same-sign dilepton final state has three main sources of background: background from prompt standard model processes, background from events where the charge of one of the leptons is misidentified, and background from non-prompt or fake leptons. No significant excess is seen above the expected background and lower limits are placed on the $X_{5/3}$ mass of 1.16 (1.10) TeV for right (left) handed chirality particle while the expected limits are 1.20 (1.15) TeV for a right (left) handed $X_{5/3}$.

    The authors present a measurement of the mass of the top quark using data corresponding to an integrated luminosity of 1.9 fb{sup -1} of p{bar p} collisions collected at {radical}s = 1.96 TeV with the CDF II detector at Fermilab's Tevatron. This is the first measurement of the top quark mass using top-antitop pair candidate events in the lepton + jets and dilepton decay channels simultaneously. They reconstruct two observables in each channel and use a non-parametric kernel density estimation technique to derive two-dimensional probability density functions from simulated signal and background samples. The observables are the top quark mass and the invariant mass of two jets from the W decay in the lepton + jets channel, and the top quark mass and the scalar sum of transverse energy of the event in the diletpon channel. They perform a simultaneous fit for the top quark mass and the jet energy scale, which is constrained in situ by the hadronic W boson mass. using 332 lepton + jets candidate events and 144 diletpon candidate events, they measure the top quark mass to be m{sub top} = 171.9 {+-} 1.7 (stat. + JES) {+-} 1.1 (other sys.) GeV/c{sup 2} = 171.9 {+-} 2.0 GeV/c{sup 2}.

  17. Dilepton bounds on left-right symmetry at the LHC run II and neutrinoless double beta decay

    Science.gov (United States)

    Lindner, Manfred; Queiroz, Farinaldo S.; Rodejohann, Werner

    2016-11-01

    In the light of the new 13 TeV dilepton data set with 3.2 fb-1 integrated luminosity from the ATLAS Collaboration, we derive limits on the Z‧ mass in the context of left-right symmetric models and exploit the complementarity with dijet and lljj data, as well as neutrinoless double beta decay. We keep the ratio of the left- and right-handed gauge coupling free in order to take into account different patterns of left-right symmetry breaking. By combining the dielectron and dimuon data we can exclude Z‧ masses below 3 TeV for gR =gL, and for gR ∼ 1 we rule out masses up to ∼ 4 TeV. Those comprise the strongest direct bounds on the Z‧ mass from left-right models up to date. We show that in the usual plane of right-handed neutrino and charged gauge boson mass, dilepton data can probe a region of parameter space inaccessible to neutrinoless double beta decay and lljj studies. Lastly, through the mass relation between WR and Z‧ we present an indirect bound on the lifetime of neutrinoless double beta decay using dilepton data. Our results prove that the often ignored dilepton data in the context of left-right models actually provide important complementary limits.

    Accomando, Elena; Fiaschi, Juri; Hautmann, Francesco; Moretti, Stefano; Shepherd-Themistocleous, Claire H.

    2017-07-01

    We present a study of di-lepton production at the CERN Large Hadron Collider with a particular focus on the contribution resulting from both real and virtual photons in the initial state. We discuss the region of phase space in which the invariant mass of the lepton pair is of the order of several TeV, where searches for new physics phenomena yielding a di-lepton signature are presently carried out. We study both the yield and associated uncertainties for all possible topologies in photon-induced di-lepton production and compare these with what is expected in the standard Drell-Yan channel, where quark-antiquark pairs are responsible for the production of lepton pairs. We analyse the impact of these QED contributions on the expected Standard Model background and on searches for new physics. In this latter case, we use the production of an extra heavy Z‧-boson predicted by the Sequential Standard Model (SSM) as a benchmark process.

    A search is performed for dark matter production with top quark pairs decaying to dileptons in proton-proton collisions at centre of mass energy $13~\\mathrm{TeV}$. Results are interpreted using simplified models for collider production of dark matter and constraints are placed on the parameter space.

  20. A measurement of the top pair production cross-section in the dilepton channel using lepton plus track selection

    Energy Technology Data Exchange (ETDEWEB)

    Mills, Corrinne Elaine [Univ. of California, Santa Barbara, CA (United States)

    2007-06-01

    Using 1.1 fb-1 of data collected by the Collider Detector at Fermilab (CDF) from Run II of the Fermilab Tevatron, they measure the t$\\bar{t}$ production cross section in events with two leptons, significant missing transverse energy, and ≥ 2 jets. As the Run II dataset grows, more stringent tests of Standard Model predictions for the top quark sector are becoming possible. The dilepton channel, where both top quarks decay t → Wb → ℓvb, is of particular interest due to its high purity even in the absence of a b jet 'tagging' requirement. Use of an isolated track as the second lepton significant increases the dilepton acceptance, at the price of some increase in background, particular from W + jets events where one of the jets is identified as a lepton. With the amount of data available, it has been possible to improve the estimate of the contribution from that background, reflected in a reduced systematic uncertainty. Assuming a branching ratio of BR(W → ℓv) = 10.8% and a top mass of mt = 175 GeV/c2, the measured cross-section is σ(p$\\bar{p}$ → t$\\bar{t}$) = 8.3 ± 1.3(stat.) ± 0.7(syst.) ± 0.5(lumi.) pb. The result is consistent with the Standard Model prediction of 6.7$+0.7\\atop{-0.9}$ pb and represents a significant improvement in precision over previous results using this selection.

  3. Measurement of the $t\\bar{t}$ spin correlations and top quark polarization in dileptonic channel with the CMS detector arXiv

    CERN Document Server

    Khatiwada, Ajeeta

    The degree of top polarization and strength of $t\\bar{t}$ correlation are dependent on production dynamics, decay mechanism, and choice of the observables. At the LHC, measurement of the top polarization and spin correlations in $t\\bar{t}$ production is possible through various observables related to the angular distribution of decay leptons. A measurement of differential distribution provides a precision test of the standard model of particle physics and probes for deviations, which could be a sign of new physics. In particular, the phase space for the super-symmetric partner of the top quark can be constrained. Results from the Compact Muon Solenoid (CMS) collaboration for top quark polarization and spin correlation in the dileptonic channel are reviewed briefly in this proceeding. The measurements are obtained using 19.5 fb$^{-1}$ of data collected in pp collisions at the center-of-mass energy of 8 TeV.

Data recorded by the CMS detector at the LHC accelerator corresponding to an integrated luminosity of 12.2 fb{sup -1} at a center-of-mass energy of 8 TeV is analyzed. Events with at least two muons or two electrons with opposite charge, a significant transverse momentum imbalance, and at least one or at least two jets are selected. Supersymmetric particle decays are expected to form an edge-like structure in the di-lepton mass spectrum. The main background from Standard-Model processes is t anti t pair production. This background is estimated in a data-driven way using the event-mixing technique. Since event mixing is novel to estimate t anti t events, the method is validated in detail. In the analyzed data no significant excess w.r.t. the event-mixing prediction is observed. In a counting experiment as well as in a fit of the shape of the distribution the data is in agreement with the expectations from the Standard Model. Hence, exclusion limits are calculated in terms of number of events forming an edge in the di-lepton mass spectrum. Additionally, the results are interpreted within a simplified model spectrum, assuming direct gaugino production and a decay chainlike {chi}{sub 2}{sup 0}{yields}l{sup {+-}}l{sup -+}{yields}{chi}{sub 1}{sup 0}l{sup +}l{sup -}. Limits are set on the masses of the supersymmetric particles. (orig.)

    We have measured the charge asymmetry in like-sign dilepton yields from B^0 B^0-bar meson decays using the CLEO detector at the Cornell Electron Storage Ring. We find a_ll = [N(l+l+) - N(l-l-)]/[N(l+l+) + N[l-l-)] = +0.013 +/- 0.050 +/- 0.005 . We combine this result with a previous, independent measurement and obtain Re(epsilon_B)/(1+|epsilon_B|^2) = +0.0035 +/- 0.0103 +/- 0.0015 (uncertainties are statistical and systematic, respectively) for the CP impurity parameter, epsilon_B.

    In the light of the new 13 TeV dilepton data set with $ 3.2\\, {\\rm fb^{-1}}$ integrated luminosity from the ATLAS collaboration, we derive limits on the $Z^{\\prime}$ mass in the context of left-right symmetric models and exploit the complementarity with dijet and $lljj$ data, as well as neutrinoless double beta decay. We keep the ratio of the left- and right-handed gauge coupling free in order to take into account different patterns of left-right symmetry breaking. By combining the dielectron and dimuon data we can exclude $Z^{\\prime}$ masses below $3$~TeV for $g_R=g_L$, and for $g_R \\sim 1$ we rule out masses up to $\\sim 4$~TeV. Those comprise the strongest direct bounds on the $Z^{\\prime}$ mass from left-right models up to date. We show that in the usual plane of right-handed neutrino and charged gauge boson mass, dilepton data can probe a region of parameter space inaccessible to neutrinoless double beta decay and $lljj$ studies. Lastly, we present a stringent indirect indirect bound on the lifetime of neu...

    Normalized differential cross sections for top quark pair production are measured in the dilepton (e-e, mu-mu, and mu-e) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are performed with data corresponding to an integrated luminosity of 2.1 inverse-femtobarns using the CMS detector at the LHC. The cross sections are measured differentially as a function of the kinematic properties of the leptons, jets from bottom quark hadronization, top quarks, and top quark pairs at the particle and parton levels. The results are compared to several Monte Carlo generators that implement calculations up to next-to-leading order in perturbative quantum chromodynamics interfaced with parton showering, and also to fixed-order theoretical calculations of top quark pair production up to next-to-next-to-leading order.

    Normalized differential cross sections for top quark pair production are measured in the dilepton ($\\mathrm{ e }^{+}\\mathrm{ e }^{-}$, $\\mu^{+}\\mu^{-}$, and $\\mu^{\\mp}\\mathrm{ e }^{\\pm}$) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are performed with data corresponding to an integrated luminosity of 2.1 fb$^{-1}$ using the CMS detector at the LHC. The cross sections are measured differentially as a function of the kinematic properties of the leptons, jets from bottom quark hadronization, top quarks, and top quark pairs at the particle and parton levels. The results are compared to several Monte Carlo generators that implement calculations up to next-to-leading order in perturbative quantum chromodynamics interfaced with parton showering, and also to fixed-order theoretical calculations of top quark pair production up to next-to-next-to-leading order.

  9. Dilepton events with displaced vertices, double beta decay, and resonant leptogenesis with Type-II seesaw dominance, TeV scale $Z'$ and RH neutrinos

    In a class of Type-II seesaw dominated $SO(10)$ models proposed recently with heavy neutrinos, extra $Z'$ boson, and resonant leptogenesis, at first we show that the lightest first generation sterile neutrino that mediates dominant contributions to neutrinoless double beta decay also generates the displaced vertex leading to verifiable like-sign di-electron as well as di-muon production events outside the LHC detectors having suppressed standard model back-ground and missing energy. Resonant leptogenesis in this case is implemented by a pair of quasi-degenerate sterile neutrinos of the second and the third generations having masses of ${\\cal O}(500)$ GeV. Then we predict a new alternative scenario where the models allow the second generation sterile neutrino mass to be ${\\cal O}(10)$ GeV capable of mediating the dominant double beta decay as well as the displaced vertices for significantly improved number of like-sign dilepton events in different channels. Resonant leptogenesis in this alternative scenario is...

  10. (YSF) Search for heavy fermionic top partners decaying to same-sign dileptons at 13 TeV

    With the discovery of the Higgs Boson during Run 1 of the Large Hadron Collider, one of the most important questions to answer during Run 2 is the naturalness problem. Composite Higgs theories answer the naturalness problem by regulating the quadratic divergences to the mass of the Higgs boson via fermionic top partners. Often predicted in such models is a top partner with charge 5e/3 which can decay to the extremely clean same-sign dilepton final state. Further, such a particle is typically the lightest of the top partners predicted and hence represents a very well motivated search. Results using 2.2 /fb of data from the CMS experiment at 13 TeV will be presented.

  11. Study of top-quark pair cross-section measurement in the dilepton channel with the ATLAS detector at the LHC

    The top quark is the heaviest of the known fundamental particles in the Standard Model (SM) with a mass of 173.3{+-}1.1 GeV. It is the sixth quark in the SM and the weak isospin partner of the bottom quark. Properties such as the mass and the cross section have been measured since its discovery in 1995 with great precision at the proton-antiproton Fermilab Tevatron Collider, Chicago at a centre-of-mass energy of 1.8 GeV and 1.96 GeV. With the start of the proton-proton CERN Large Hadron Collider (LHC), Geneva, a new record in the centre-of-mass energy was achieved. The LHC opens a new energy frontier and probes the SM at energies of the electroweak symmetry-breaking scale and beyond. The measurement of the top-quark pair cross-section at this new energy is an important step, since it will either re-establish the SM at these energies by confirming the theoretical calculations or it can point to new phenomena that help to understand the so far not explained experimental findings in particle physics and cosmology. This thesis presents a study of the production cross-section measurement of top-quark pair in the dilepton channel at the LHC with the ATLAS experiment at a centre-of-mass energy of {radical}(s)=10 TeV and for a data amount of L{sub int.}=200 pb{sup -1}. This study investigates the performance of the cross-section measurement with a cut-and-count analysis on Monte Carlo simulated samples. Important background processes are taken into account such as leptonically decaying Z-boson and single top-quark events. Data-driven background methods for Z-boson and fake event rates are discussed. A full list of systematic uncertainties is investigated and finally combined with the statistical uncertainties in a likelihood to extract the combined uncertainty. A ''top mass''-like variable is presented that can help to distinguish dileptonic top-quark pair decays from similar signatures in new physics models. The combined sensitivity of the analysis in

    Full Text Available We measure the top quark mass in dilepton final states of tt¯ events in pp¯ collisions at s=1.96 TeV, using data corresponding to an integrated luminosity of 9.7 fb−1 at the Fermilab Tevatron Collider. The analysis features a comprehensive optimization of the neutrino weighting method to minimize the statistical uncertainties. We also improve the calibration of jet energies using the calibration determined in tt¯→lepton+jets events, which reduces the otherwise limiting systematic uncertainty from the jet energy scale. The measured top quark mass is mt=173.32±1.36(stat±0.85(syst GeV.

    A search for a Higgs boson decay $H\\to\\gamma^*\\gamma\\to\\ell\\ell\\gamma$ is presented. The analysis is performed using proton-proton collision data recorded by the CMS detector at the CERN LHC at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb$^{-1}$. The selected events have an opposite-sign muon or electron pair and a high transverse momentum photon. No excess above background has been found in the three-body invariant mass range $120decay, where the dilepton invariant mass is less than 20 GeV. For a Higgs boson with $m_H=125$ GeV, a $95\\%$ confidence level (CL) exclusion observed (expected) limit is 6.7 ($5.9^{+.2.8}_{-1.8}$) times the standard model prediction.

    We present a measurement of W boson polarization in top-quark decays in t{bar t} events with decays to dilepton final states using 5.1 fb{sup -1} integrated luminosity in p{bar p} collisions collected by the CDF II detector at the Tevatron. A simultaneous measurement of the fractions of longitudinal (f{sub 0}) and right-handed (f{sub +}) W bosons yields the results f{sub 0} = 0.71{sub -0.17}{sup +0.18}(stat) {+-} 0.06(syst) and f{sub +} = -0.07 {+-} 0.09(stat) {+-} 0.03(syst). Combining this measurement with our previous result based on single lepton final states, we obtain f{sub 0} = 0.84 {+-} 0.09(stat) {+-} 0.05(syst) and f{sub +} = -0.16 {+-} 0.05(stat) {+-} 0.04(syst). The results are consistent with standard model expectation.

  15. Dileptons and Chiral Symmetry Restoration

    Hohler, P M

    2015-01-01

    We report on recent work relating the medium effects observed in dilepton spectra in heavy-ion collisions to potential signals of chiral symmetry restoration. The key connection remains the approach to spectral function degeneracy between the vector-isovector channel with its chiral partner, the axialvector-isovector channel. Several approaches are discussed to elaborate this connection, namely QCD and Weinberg sum rules with input for chiral order parameters from lattice QCD, and chiral hadronic theory to directly evaluate the medium effects of the axialvector channel and the pertinent pion decay constant as function of temperature. A pattern emerges where the chiral mass splitting between rho and a_1 burns off and is accompanied by a strong broadening of the spectral distributions.

    We have searched a sample of 9.6 M BB¯ events collected with the CLEO II detector in e+e − annihilations at the ϒ(4S) resonance for B meson decays as follows: (1) The flavor-changing neutral current decays, B → K ℓ +ℓ− and B → K*(892)ℓ+ℓ− with mℓℓ > 0.5 GeV. (2) The lepton-flavor-violating decays, B → h e±μ ∓, B+ → h −e+e +, B+ → h −e+μ+, and B+ → h−μ +μ+, where h is π, K, ρ and K*(892), a total of sixteen modes. (3) The lepton-flavor-violating leptonic decays including τ lepton, B0 → μ±τ ∓ and B0 → e ±τ∓.

  17. Exploring the LHC Landscape with Dileptons

    Bourilkov, Dimitri

    2016-01-01

    The dilepton decay channels provide clean signatures and are an ideal hunting ground for high mass resonant, like Z', or non-resonant, like contact interactions or extra dimensions, searches at the LHC. The production of high invariant mass opposite sign lepton pairs in proton-proton collisions in the Standard Model is dominated by the Drell-Yan process. In addition to this photon or Z exchange mediated mechanism, photons radiated by the incoming protons can collide and produce lepton pairs. In this paper detailed calculations of the Drell-Yan process at next-to-next-to-leading order in QCD and next-to-leading order in the electroweak corrections, augmented with the photon-induced effects, are presented in the typical acceptance of a multi-purpose LHC detector at center of mass energy 13 TeV. Estimates of the expected backgrounds for new physics searches are provided for dilepton invariant masses up to the LHC kinematic limit.

  20. submitter A search for the Higgs boson decaying to two b-quarks in association with a dileptonically decaying top-quark pair with the ATLAS detector

    Connelly, Ian Allan

    Details of a search for Higgs production in association with a top-quark pair, where the Higgs decays to two b-quarks, are presented using 20.3 fb−1 of √ s = 8 TeV data from the ATLAS detector at the LHC. Whilst the existence of the Higgs boson has been established, there has yet to be a direct observation of the Higgs boson coupling to top quarks. This search aims to provide a measurement of the top-Higgs coupling to probe the nature of the Standard Model of particle physics. Dileptonic top-quark pair events are used to measure the b-tagging efficiency on data and to search for this Higgs production mechanism. To separate the sought after signal events from the large amount of background events, the application of a technique known as the matrixelement method is presented. An investigation into the impact on the discovery significance using this technique is carried out, resulting in an 8% improvement in sensitivity relative to the nominal analysis.

    A search for resonances decaying to top quark-antiquark pairs is performed using a dilepton+jets data sample recorded by the CMS experiment at the LHC in pp collisions at $\\sqrt{s}$ = 7 TeV corresponding to an integrated luminosity of 5.0 inverse femtobarns. No significant deviations from the standard model background are observed. Upper limits are presented for the production cross section times branching fraction of top quark-antiquark resonances for masses from 750 to 3000 GeV. In particular, the existence of a leptophobic topcolor particle Z' is excluded at the 95% confidence level for resonance masses M[Z'] < 1.3 TeV for Gamma[Z'] = 0.012 M[Z'], and M[Z'] < 1.9 TeV for Gamma[Z'] = 0.10 M[Z'].

  4. Superluminal light propagation via quantum interference in decay channels

    We examine the propagation of a weak probe light through a coherently driven $Y$-type system. Under the condition that the excited atomic levels decay via same vacuum modes, the effects of quantum interference in decay channels are considered. It is found that the interference in decay channels results in a lossless anomalous dispersion between two gain peaks. We demonstrate that the probe pulse propagation can in principle be switched from subluminal to superluminal due to the decay-induced ...

    Although the phenomena of r – w interference has been studied at great length in pionic decay channel over the past 50 years, a study of the interference in a purely electromagnetic production and decay channel has never been performed on an elementary proton target until now. The only published photo-production data of the r - w leptonic decay channel was obtained in the early seventies on C and Be. An investigation of the r - w interference on a Hydrogen was recently completed at Jefferson Lab with the CLAS detector. The di-lepton spectra was fit with two inter- fering relativistic Breit-Wigner functions, and the interference phase was extracted. Preliminary results will be compared to the previous experimental studies in nuclei.

  6. Search for light custodians in a clean decay channel at the LHC

    Models of warped extra dimensions with custodial symmetry usually predict the existence of a light Kaluza-Klein fermion arising as a partner of the right-handed top quark, sometimes called light custodians which we will denote $\\tilde{b}_R$. The production of these particles at the LHC can give rise to multi-W events which could be observed in same-sign dilepton channels, but its mass reconstruction is challenging. In this letter we study the possibility of finding a signal for the pair production of this new particle at the LHC focusing on a rarer, but cleaner decay mode of a light custodian into a $Z$ boson and a $b$-quark. In this mode it would be possible to reconstruct the light custodian mass. In addition to the dominant standard model QCD production processes, we include the contribution of a Kaluza-Klein gluon first mode. We find that the $\\tilde{b}_R$ stands out from the background as a peak in the $b Z$ invariant mass. However, when taking into account only the electronic and muonic decay modes of t...

    The top quark mass is measured in the t t bar →dilepton channel (lepton = e , μ) using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton-proton centre-of-mass energy of √{ s} = 8 TeV and correspond to an integrated luminosity of about 20.2 fb-1. Exploiting the template method, and using the distribution of invariant masses of lepton- b-jet pairs, the top quark mass is measured to be mtop = 172.99 ± 0.41 (stat) ± 0.74 (syst) GeV, with a total uncertainty of 0.84 GeV. Finally, a combination with previous ATLAS mtop measurements from √{ s} = 7 TeV data in the t t bar →dilepton and t t bar →lepton +jets channels results in mtop = 172.84 ± 0.34 (stat) ± 0.61 (syst) GeV, with a total uncertainty of 0.70 GeV.

    In this thesis a search for Supersymmetry in the opposite-sign same-flavor di-lepton channelis presented. Data recorded by the CMS detector at the LHC accelerator corresponding to anintegrated luminosity of 12.2 fb−1 at a center-of-mass energy of 8 TeV is analyzed. Events withat least two muons or two electrons with opposite charge, a significant transverse momentumimbalance, and at least one or at least two jets are selected. Supersymmetric particle decays areexpected to form an edge-like structure in the di-lepton mass spectrum. The main backgroundfrom Standard-Model processes is t¯ pair production. This background is estimated in a datatdriven way using the event-mixing technique. Since event mixing is novel to estimate t¯ events,tthe method is validated in detail.In the analyzed data no significant excess w. r. t. the event-mixing prediction is observed. In acounting experiment as well as in a fit of the shape of the distribution the data is in agreementwith the expectations from the Standard Mode...

  11. Measurement of top-antitop differential cross sections in the di-lepton channel with ATLAS in p-p collisions at 7TeV

    This dissertation presents a measurement of differential cross sections as a function of mass, transverse momentum and rapidity of the top quark pairs using $\\sqrt{s}$=7TeV proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider. This data corresponds to an integrated luminosity of 4.6fb$^{−1}$. Events with top quark pair signatures are selected in the di-lepton channel. The reconstructed differential distributions are subtracted with estimated backgrounds and are corrected for detector response and acceptance to the top parton level. The measured differential cross sections are compared with different Monte Carlo generators of top quark pair production. The results are consistent with the Standard Model predictions and with the differential cross section results measured in the lepton+jets channel.

    We report a measurement of the top quark mass, M{sub t}, in the dilepton decay channel of t{bar t} {yields} b{ell}{prime}{sup +} {nu}{sub {ell}}, {bar b}{ell}{sup -}{bar {nu}}{sub {ell}} using an integrated luminosity of 1.0 fb{sup -1} of p{bar p} collisions collected with the CDF II detector. We apply a method that convolutes a leading-order matrix element with detector resolution functions to form event-by-event likelihoods; we have enhanced the leading-order description to describe the effects of initial-state radiation. The joint likelihood is the product of the likelihoods from 78 candidate events in this sample, which yields a measurement of M{sub t} = 164.5 {+-} 3.9(stat.) {+-} 3.9(syst.) GeV/c{sup 2}, the most precise measurement of M{sub t} in the dilepton channel.

    We report the most restrictive direct limits on masses of fourth-generation down-type quarks b{'}, and quarklike composite fermions (B or T{5/3}), decaying promptly to tW{-/+}. We search for a significant excess of events with two same-charge leptons (e, mu), several hadronic jets, and missing transverse energy. An analysis of data from pp collisions with an integrated luminosity of 2.7 fb{-1} collected with the CDF II detector at Fermilab yields no evidence for such a signal, setting mass limits m{b{'}}, m{B}>338 GeV/c{2} and m{T{5/3}}>365 GeV/c{2} at 95% confidence level.

  15. Background rejection in dilepton analysis with CBM-MVD

    The light vector mesons ρ, ω and φ are known to be excellent probes of the strongly interacting matter under extreme conditions. The leptonic decay channels of these mesons are of special interest as the leptons leave the hot and dense fireball without strong interaction and may reveal information on the characteristics of the matter created in the collisions. However, electrons and positrons from γ-conversions and Dalitz decays of π{sup 0} are the main contributors to a large combinatorial background obscuring the information carried by the rare dileptons. The Micro-Vertex Detector (MVD) of the Compressed Baryonic Matter (CBM) experiment can contribute to reduce this background by reconstructing the low momentum partner of background pair in the MVD. CBM has no detectors for electron identification in front of the magnetic field posing an additional challenge to dielectron analysis. Methods for background rejection are presented.

  16. Measurement of the Top Quark Mass in the Di-lepton Channel using the Dalitz-Goldstein Method

    This dissertation describes a measurement of the mass of the top quark using a method developed by G. Goldstein and R.H. Dalitz. It is based on 2.0 fb-1 of data collected by the Collider Detector Facility at Fermi National Accelerator Laboratories. Di-lepton events were observed from colliding protons with anti-protons with √s = 1.96 TeV in the Tevatron Collider. A total of 145 candidate events were observed with 49 expected to be from background. These events include two neutrinos which elude detection. The method begins by assuming an initial top quark mass and solves for the neutrino momenta using a geometrical construction. The method samples over a range of likely top quark masses choosing the most consistent mass via a likelihood function. An important distinguishing feature of this method from others is its lack of dependence on the missing transverse energy, a quantity that is poorly measured by the experiment. This analysis determines the top quark mass to be Mtop = 172.3 ± 3.4(stat.) ± 2.0(syst.) GeV/c2 (Mtop = 170.5 ± 3.7(stat.) ± 1.8(syst.) GeV/c2 with b-tagging).

  17. Non-equilibrium dilepton production in hadronic transport approaches

    2016-01-01

    In this work the non-equilibrium dilepton production from a hadronic transport approach (SMASH) is presented. The dilepton emission from the hadronic stage is of interest for current HADES results measured at GSI in the beam energy range from 1.25 - 3.5 GeV. Also at high collision energies (RHIC/LHC) the later dilute stages of the reaction are dominated by hadronic dynamics. The newly developed hadronic transport approach called SMASH (=Simulating Many Accelerated Strongly-interacting Hadrons) is introduced first. After explaining the basic interaction mechanisms, a comparison of elementary cross sections for pion production to experimental data is shown. The dilepton production within SMASH is explained in detail. The main contribution to the dilepton spectra in the low energy regime of GSI/FAIR/RHIC-BES originates from resonance decays. Results of the dilepton production with SMASH such as invariant mass spectra are shown.

  18. Measurements of exclusive dilepton production at 7 and 8 TeV with the ATLAS detector

    In the absence of forward proton tagging, exclusive processes can be distinguished in the central part of the ATLAS detector exploiting the large rapidity gap in the central region and the absence of charged particles reconstructed in the inner tracking detector. This strategy has been exploited to study the exclusive production of dilepton pairs in the data taken at centre­of­mass energies of 7 and 8 TeV. A measurement of exclusive production of dileptons (ee and mumu) in 7 TeV pp collisions is presented. The results show significant deviations from the pure QED prediction, which can be explained by photon coherence and proton rescattering effects. A new analysis performed at 8 TeV concentrates on the emu final state to search for the exclusive production of WW boson pairs. Furthermore the analysis is re­optimised to search for the exclusive production of the Higgs boson in the WW* decay channel.

    The top quark was discovered by CDF and D0 in 1995, in Tevatron Run I. This thesis presents the results of the top production cross-section measurement in the dilepton channel, using data taken at the Collider Detector at Fermilab (CDF) in pp¯ collisions, at a center-of- mass energy of s = 1.96 TeV. The dataset represents an integrated luminosity of 193 pb−1 and was collected between the period March 2002–September 2003. Thirteen events were observed (1 e/e, 9 e/μ, 3 μ/μ), passing the selection requirements, with an estimated background of 2.8 ± 0.7 events. These are used to measure a tt¯ cross- section of σtt¯ = 8.4+3.2-2.7 (stat) +1.5-1.1 (syst) ± 0.5 (lum)pb. This is in a good agreement with the Standard Model prediction of σtt¯ = 6.7+0.71-0.88 pb, for a top quark mass of 175 GeV/c2. Also a few kinematical distributions are compared with the Standard Model and found to agree w...

    This Letter reports on a search for narrow high-mass resonances decaying into dilepton final states. The data were recorded by the ATLAS experiment in pp collisions at $\\sqrt{s}$ = 7 TeV at the LHC and correspond to a total integrated luminosity of 1.08/fb (1.21/fb) in the ee (mumu) channel. No statistically significant excess above the Standard Model expectation is observed and upper limits are set at the 95% C.L. on the cross section times branching ratio of Z' resonances and Randall-Sundrum gravitons decaying into dileptons as a function of the resonance mass. A lower mass limit of 1.83 TeV on the Sequential Standard Model Z' boson is set. A Randall-Sundrum graviton with coupling $k/\\overline{M}_{Pl}$=0.1 is excluded at 95% C.L. for masses below 1.63 TeV.

  1. Streamwise decay of localized states in channel flow

    Channel flow, the pressure driven flow between parallel plates, has exact coherent structures that show various degrees of localization. For states which are localized in streamwise direction but extended in spanwise direction, we show that they are exponentially localized, with decay constants that are different on the upstream and downstream side. We extend the analysis of Brand and Gibson, J. Fluid Mech. 750, R1 (2014), for stationary states to the case of advected structures that is needed here, and derive expressions for the decay in terms of eigenvalues and eigenfunctions of certain second order differential equations. The results are in very good agreement with observations on exact coherent structures of different transversal wave length.

  2. Same-Sign Dilepton Excesses and Light Top Squarks

    2015-01-01

    Run 1 data of the Large Hadron Collider (LHC) contain excessive events in the same-sign dilepton channel with b-jets and missing transverse energy (MET), which were observed by five separate analyses from ATLAS and CMS collaborations. We show that these events could be explained by direct production of top squarks (stops) in supersymmetry. In particular, a right-handed stop with a mass of 550 GeV decaying into 2 t quarks, 2 W bosons, and MET could fit the observed excess without being constrained by other direct search limits from Run 1. We propose kinematic cuts at 13 TeV to enhance the stop signal, and estimate that stops could be discovered with 40 inverse fb of integrated luminosity at Run 2 of the LHC, when considering only the statistical uncertainty.

    Search for gluino-pair & squark -pair productions in p-p collisions with early 13 TeV ATLAS data. Two signal scenarios are considered, both provide large missing energy and e +e-/μ+μ- dilepton pair but with different shape signatures in the invariant mass spectrum. 14.7/fb of 13 TeV ATLAS e+e-/μ+μ- dilepton data is analyzed. The results of the observation exclude the gluino masses as large as 1.7 TeV.

    With the HADES spectrometer at GSI we have studied dilepton production in various collision systems from elementary N+N, over p+A, up to the medium-heavy Ar+KCl system. We have confirmed the puzzling results of the former DLS collaboration at the Bevalac. While we have traced the origin of the excess pair yield in C+C collisions to elementary p+p and n+p processes, we find a significant contribution from the dense phase of the collision in larger Ar+KCl system. From recently obtained e+e- pair spectra in p+p and p+Nb interactions at 3.5 GeV kinetic beam energy the inclusive production cross sections for neutral pions, η , ω and ρ mesons are extracted for the first time at this beam energy. Furthermore, the production mechanisms of the vector mesons, which are not known at these energies, are investigated. The direct comparison of p+p and p+Nb data allows us to investigate in-medium mass modifications of vector mesons at nuclear ground state density. On the other hand, exclusive production of ω and η mesons in p+p reactions at 3.5 GeV were studied via their π+π-π0 decay channel. Production cross sections and angular distributions for both states were determined.

    We measure the top quark mass using approximately 359 pb-1 of data from p$\\bar{p}$ collisions at √s =1.96 GeV at CDF Run II. We select t$\\bar{t}$ candidates that are consistent with two W bosons decaying to a charged lepton and a neutrino following t$\\bar{t}$ → W+W-b$\\bar{b}$ → l+l-v$\\bar{v}$b$\\bar{b}$.

  6. Precise calculation of the dilepton invariant-mass spectrum and the decay rate in B{sup {+-}}{yields}{pi}{sup {+-}}{mu}{sup +}{mu}{sup -} in the SM

    We present a precise calculation of the dilepton invariant-mass spectrum and the decay rate for B{sup {+-}}{yields}{pi}{sup {+-}}l{sup +}l{sup -} (l{sup {+-}}=e{sup {+-}},{mu}{sup {+-}}) in the Standard Model (SM) based on the effective Hamiltonian approach for the b{yields}dl{sup +}l{sup -} transitions. With the Wilson coefficients already known in the next-to-next-to-leading logarithmic (NNLL) accuracy, the remaining theoretical uncertainty in the short-distance contribution resides in the form factors f{sub +}(q{sup 2}), f{sub 0}(q{sup 2}) and f{sub T}(q{sup 2}). Of these, f{sub +}(q{sup 2}) is well measured in the charged-current semileptonic decays B{yields}{pi}l{nu}{sub l} and we use the B-factory data to parametrize it. The corresponding form factors for the B{yields}K transitions have been calculated in the Lattice-QCD approach for large-q{sup 2} and extrapolated to the entire q{sup 2}-region using the so-called z-expansion. Using an SU(3){sub F}-breaking Ansatz, we calculate the B{yields}{pi} tensor form factor, which is consistent with the recently reported lattice B{yields}{pi} analysis obtained at large q{sup 2}. The prediction for the total branching fraction B(B{sup {+-}}{yields}{pi}{sup {+-}}{mu}{sup +}{mu}{sup -})=(1.88{sub +0.32}{sup -0.21}) x 10{sup -8} is in good agreement with the experimental value obtained by the LHCb collaboration. In the low q{sup 2}-region, the Heavy-Quark Symmetry (HQS) relates the three form factors with each other. Accounting for the leading-order symmetry-breaking effects, and using data from the charged-current process B{yields}{pi}l{nu}{sub l} to determine f{sub +}(q{sup 2}), we calculate the dilepton invariant-mass distribution in the low q{sup 2}-region in the B{sup {+-}}{yields}{pi}{sup {+-}}l{sup +}l{sup -} decay. This provides a model-independent and precise calculation of the partial branching ratio for this decay.

    The top quark mass was measured in the channels $t\\bar{t} \\to \\mathrm{lepton+jets}$ and $t\\bar{t} \\to \\mathrm{dilepton}$ (lepton=$e, \\mu$) based on ATLAS data recorded in 2011. The data were taken at the LHC with a proton--proton centre-of-mass energy of $\\sqrt{s}=7$ TeV and correspond to an integrated luminosity of 4.6fb$^{-1}$. The $t\\bar{t} \\to \\mathrm{lepton+jets}$ analysis uses a three-dimensional template technique which determines the top quark mass together with a global jet energy scale factor (JSF), and a relative $b$-to-light-jet energy scale factor (bJSF), where the terms $b$-jets and light-jets refer to jets originating from $b$-quarks and $u, d, c, s$-quarks or gluons, respectively. The analysis of the $t\\bar{t} \\to \\mathrm{dilepton}$ channel exploits a one-dimensional template method using the $m_{\\ell b}$ observable, defined as the average invariant mass of the two lepton+$b$-jet pairs in each event. The top quark mass is measured to be $172.33\\pm 0.75(\\rm {stat}) \\pm 1.02(\\rm {syst})$ GeV, an...

    The production cross section for t$\\bar{t}$ pairs decaying into two lepton final states was measured using data from the D0 detector at Fermilab. The measurement was made using a lepton+track selection, where one lepton is fully identified and the second lepton is observed as an isolated track. This analysis is designed to complement similar studies using two fully identified leptons [1]. The cross section for the lepton+track selection was found to be σ = 5.2-1.4+1.6(stat)-0.8+0.9(syst) ± 0.3(lumi) pb. The combined cross section using both the lepton+track data and the data from the electron+electron, electron+muon, and muon+muon samples is: σ = 6.4-0.9+0.9(stat)-0.7+0.8(syst) ± 0.4(lumi) pb.

    A search is described for a Higgs boson decaying into two photons, one of which has an internal conversion to a muon or an electron pair ($\\ell\\ell\\gamma$). The analysis is performed using proton-proton collision data recorded with the CMS detector at the LHC at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb$^{-1}$. The events selected have an opposite-sign muon or electron pair and a high transverse momentum photon. No excess above background has been found in the three-body invariant mass range $ 120 < m_{\\ell\\ell\\gamma} < 150$ GeV, and limits have been derived for the Higgs boson production cross section times branching fraction for the decay $\\mathrm{H} \\to \\gamma^* \\gamma \\to \\ell \\ell \\gamma$, where the dilepton invariant mass is less than 20 GeV. For a Higgs boson with $m_{\\mathrm{H}} =$ 125 GeV, a 95% confidence level (CL) exclusion observed (expected) limit is 7.7 (6.4$^{+3.1}_{-2.0}$) times the standard model prediction.

    The top quark is the heaviest standard model quark. Discovered in 1995 by the two Tevatron experiments it has atypical properties. In particular its time life is so short that it decays before hadronizing, so the top quark mass could be measured with a high precision. Data collected by the DØ experiment between 2002 and 2009, which represent an integrated luminosity of 5.4 fb⁻¹, are used to measure the top quark mass by using the matrix element method in the three dilepton channels: dielectron, electron--muon and dimuon. The measured mass, 174.0 ± 1.8 (stat.) ± 2.4 (syst.) GeV, is in a good agreement with other measurements and limited by the systematic uncertainties for the first time in these channels. In this thesis different approaches have been studied to improve the accuracy of this measurement: the use of b-quark jet identification in order to optimize the selection of top--anti-top events and a better determination of the main systematic uncertainties. A special attention has been paid to the Monte-Carlo simulation of muons in D0: the improved smearing procedure for the simulated muons, discussed in this thesis, will be used to increase the accuracy of the top properties measurements as well as the precision of many other D0 measurements.

  13. Top Mass Determination in the ttbar Semileptonic Decay Channel

    Sonnenschein, Lars

    2001-01-01

    The proton proton collider LHC will operate at sqrt( s)=14TeV center of mass energy. The NLO cross section for the production of ttbar events reachs at this energy about 800pb. This leads, already for a start-up luminosity of L=10^33 cm^-2 s^-1, corresponding to an integrated luminosity of 10fb^-1, to the huge production rate of 8*10^6 ttbar events per year. This will result in 3.5*10^6 ttbar events in the semileptonic decay channel ttbar -> b W^+ bbar W^- -> b bbar q qbar l neutrino. This signature is used for simulations, including the response of the CMS detector, to determine the top mass in the hadronic decay branch via the invariant three jet mass m( jjj). The invariant mass m( jj) of the light quark jets is scaled to the known W boson mass. The top quark mass is then reconstructed by the invariant mass of the three jet system consisting of a b jet and the scaled light quarkjets. After the event selection criteria are applied a background free sample of about 5000 events remains. This lead...

  14. Vector meson photoproduction studied in its radiative decay channel

    CERN Document Server

    Zhao, Q; Cole, P L; Zhao, Qiang

    2005-01-01

    We provide an analysis of vector meson photoproduction in the channel of the vector meson decaying into a pseudoscalar meson plus a photon, i.e. $V\\to P\\gamma$. It is shown that non-trivial kinematic correlations arise from the measurement of the $P\\gamma$ angular distributions in the overall c.m. system in comparison with those in the vector-meson-rest frame. In terms of the vector meson density matrix elements, the implication of such kinematic correlations in the measurement of polarization observables is discussed. For the $\\omega$ meson production, due to its relatively large branching ratios for $\\omega\\to\\pi^0\\gamma$, additional events from this channel may enrich the information about the reaction mechanism and improve the statistics of the recent measurement of polarized beam asymmetries by the GRAAL Collaboration. For $\\phi\\to \\eta\\gamma$, $\\rho\\to \\pi\\gamma$, and $K^*\\to K\\gamma$, we expect that additional information about the spin structure of the vector meson production vertex can be derived.

  15. Same-Sign Dilepton Excesses and Vector-like Quarks

    Chen, Chuan-Ren; Low, Ian

    2015-01-01

    Multiple analyses from ATLAS and CMS collaborations, including searches for ttH production, supersymmetric particles and vector-like quarks, observed excesses in the same-sign dilepton channel containing b-jets and missing transverse energy in the LHC Run 1 data. In the context of little Higgs theories with T parity, we explain these excesses using vector-like T-odd quarks decaying into a top quark, a W boson and the lightest T-odd particle (LTP). For heavy vector-like quarks, decay topologies containing the LTP have not been searched for at the LHC. The bounds on the masses of the T-odd quarks can be estimated in a simplified model approach by adapting the search limits for top/bottom squarks in supersymmetry. Assuming a realistic decay branching fraction, a benchmark with a 750 GeV T-odd b-prime quark is proposed. We also comment on the possibility to fit excesses in different analyses in a common framework.

    Ni, Dongdong; Ren, Zhongzhou

    The generalized density-dependent cluster model is devoted to calculate α-decay half-lives of spherical and deformed nuclei. The multi-channel cluster model is developed to describe the α-decay fine structure in heavy deformed nuclei, including half-lives and branching ratios. After a brief review of these two models, special cases of the α-decay fine structure are presented. Calculations are separately performed using the coupled-channels and WKB approaches.

    Quantum Entanglement between the two neutral mesons produced in meson factories has allowed the first indisputable direct observation of Time Reversal Violation in the time evolution of the neutral meson between the two decays. The exceptional meson transitions are directly connected to semileptonic and CP-eigenstate decay channels. The possibility of extending the observable asymmetries to more decay channels confronts the problem of the "orthogonality condition", which can be stated with this tongue-twister: Given a decay channel $f$, Which is the decay channel $f'$ such that the meson state not decaying to $f'$ is orthogonal to the meson state not decaying to $f$? In this paper we propose an alternative $T$-Violation Asymmetry at meson factories which allows its opening to any pair of decay channels.

    Quantum entanglement between the two neutral mesons produced in meson factories has allowed the first indisputable direct observation of Time Reversal Violation in the time evolution of the neutral meson between the two decays. The exceptional meson transitions are directly connected to semileptonic and CP eigenstate decay channels. The possibility of extending the observable asymmetries to more decay channels confronts the problem of the “orthogonality condition”, which can be stated with this tongue-twister: Given a decay channel f, which is the decay channel f{sup ′} such that the meson state not decaying to f{sup ′} is orthogonal to the meson state not decaying to f? In this Letter we propose an alternative T-Violation asymmetry at meson factories which allows its opening to any pair of decay channels. Instead of searching which is the pair of decay channels associated to the T-reverse meson transition, we build an asymmetry which tags the initial states of both the Reference and the T-reverse meson transitions. This observable filters the appropriate final states by means of two measurable survival probabilities. We discuss the methodology to be followed in the analysis of the new observable and the results expected in specific examples.

    A search is presented for the Standard Model (SM) Higgs boson optimized in the decay channel $H → W^{+} W^{−}$, where both bosons decay leptonically. The final state considered contains dileptons and missing transverse energy from the neutrinos. A multivariate analysis is used to suppress the background. No significant excess above the SM background has been observed and limits set on the Higgs boson production cross-section $∗$ the branching ratio for $m_{H} = 115–200$ GeV are computed. Results using 8.1 fb−1 of data are presented.

  20. Phenomenology of Sarks and Dileptons

    Science.gov (United States)

    Chaudhry, Jyoti

    We have studied three extensions of the standard model; the sark model, the vector quark model and the 331 model. The sark model has a gauge group SU(2) _{X}otimes SU(3)_{C} otimes SU(2)_{S}otimes U(1) _{Q}, where all gauge symmetries are unbroken. The vector-quark model contains an extra vector-like quark doublet. Finally, the 331 model has a gauge group SU(3)_{C}otimes SU(3)_{L}otimes U(1)_{X } where SU(3)otimes U(1)_ {X} contains the standard electroweak group SU(2)_{L}otimes U(1) _{Y}. This model contains three extended fermion families with the third family treated differently and additional vector gauge bosons. In the sark model, the number of quark-lepton families is constrained to three by the asymptotic freedom for the SU(2)_{X} group. Further, quantization of the electric charge is achieved by the anomaly cancellation conditions. Neutral sark baryons, called narks, are candidates for the cosmological dark matter having the characteristics designed for WIMPS. Further phenomenological implications of sarks are analyzed including electron-positron annihilation, Z^{0 } decay, flavor-changing neutral currents, baryon-number non-conservation, sarkonium and the neutron electric dipole moment. Next, we have studied the CP violation parameter Re(epsilon^'/epsilon) in the vector-quark model and also in the 331 model. For a given value of m_{t}, the vector quark model tends to reduce Re(epsilon ^'/epsilon) whereas the 331 model tends to increase it. If m_{t } is discovered around 150 GeV and the lower experimental value for Re(epsilon^ '/epsilon) (0.74+/- 0.60times 10^{-3}, Fermilab) is confirmed, the standard model is acceptable. But, if its higher value (2.3+/- 0.65times 10 ^{-3}, CERN) persists, a dynamics like the 331 model seems to be favored. Lastly, we have looked for the signatures of the dileptons in e^-p and e ^-e^+ colliders. At HERA, with the center-of-mass energy 314 GeV, a dilepton mass above 150 GeV is inaccessible but at LEPII-LHC, with a 1790 Ge

  1. A Measurement of the Mass of the Top Quark in the Di-Lepton Channels Using the DØ Detector at Fermilab

    Fatakia, Sarosh Noshir [Boston Univ., MA (United States)

    2005-01-01

    This dissertation describes a measurement of the mass of the top quark using events consistent with the hypothesis t¯t → bW+ ¯bW- → bl+ν¯bl-¯ν, where (l=e,μ). The events are obtained from nearly 230 pb-1 of p¯p collision data collected by the DØ experiment between 2002 and 2004 during Run II. In this decay channel two neutrinos remain undetected. Extraction of the mass of the top quark by kinematic reconstruction is not possible because the event is under-constrained. Therefore, a dynamical likelihood method is developed to obtain the mass of the top quark. The mass of top quark obtained from the candidate events selected in the di-electron channel and the eμ channel is: 154.1 +14.2-12.8(stat.) ±6.6 (syst.) GeV.

    The measurements of the properties of the Higgs boson are presented in the H$\\rightarrow$ZZ$\\rightarrow$4$\\ell$ ($\\ell$=e,$\\mu$) decay channel using a data sample corresponding to an integrated luminosity of 35.9 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the CMS detector at the LHC. The signal-strength modifier $\\mu$, defined as the production cross section of the Higgs boson times its branching fraction to four leptons relative to the standard model expectation, is measured to be $\\mu=1.05^{+0.19}_{-0.17}$ at $m_{\\mathrm{H}}=125.09~\\mathrm{GeV}$. Constraints are set on the strength modifiers for the main Higgs boson production modes. The mass is measured to be $m_{\\mathrm{H}}=125.26 \\pm 0.21~\\mathrm{GeV}$ and the width is constrained using on-shell production to be $\\Gamma_{\\mathrm{H}}<1.10~\\mathrm{GeV}$, at $95\\%$ CL.

  3. Dilepton production from RHIC to the LHC

    Directory of Open Access Journals (Sweden)

    Dahms Torsten

    2015-01-01

    Full Text Available The goal of ultrarelativistic heavy-ion collisions at RHIC and the LHC is to study the properties of the quark-gluon plasma (QGP, a phase of matter with partonic degrees of freedom. Electromagnetic radiation, in form of photons or lepton pairs, is a penetrating probe that allows the investigation of the full time evolution and dynamics of the produced matter as it does not undergo strong interaction in the final state. The dilepton spectrum is extremely rich in physics sources: Thermal black-body radiation is of particular interest as it carries information about the QGP temperature. Modifications of the spectral functions of light vector mesons are linked to the potential restoration of chiral symmetry in the QGP phase. Correlated lepton pairs from semi-leptonic charm and beauty decays provide additional information about the heavy-quark energy loss. Finally, the suppression of quarkonia in the QGP give access to an independent temperature measurement. In this proceedings, dilepton results from RHIC are reviewed and the status as well as prospects of low-mass dilepton measurements at the LHC are given.

  4. Search For Gluino Pair Production Using Like-sign Top Dilepton Events

    CERN Document Server

    Smith, C E

    2002-01-01

    We present the results of a search for supersymmetry via gluino pair production in pp¯ collisions at s = 1.8 TeV. The data sample represents the full 106.1 pb−1 of integrated luminosity collected by the Collider Detector at Fermilab (CDF) during Run I of the Tevatron. The gluino, a supersymmetric partner of the gluon, is expected to be strongly produced at the Tevatron. The scalar top, superpartner of the top quark, is believed to be the lightest squark and the only squark less massive than the gluino. In the region of parameter spaced defined by (mt + mt˜ ) < mg˜ < ( mq + mq˜), ( g˜ → tt˜) is the preferred decay channel. The Majorana nature of the gluino gives rise to like-sign top quarks from gg˜ events. We use the top dilepton analysis to search for this unique signature in the like-sign dilepton channel, and we set upper limits on the cross section for gluino-gluino production. Despite a low expected ...

    In this work the SMASH model is presented ("Simulating Many Accelerated Strongly-Interacting Hadrons"), a next-generation hadronic transport approach, which is designed to describe the non-equilibrium evolution of hadronic matter in heavy-ion collisions. We discuss first dilepton spectra obtained with SMASH in the few-GeV energy range of GSI/FAIR, where the dynamics of hadronic matter is dominated by the production and decay of various resonance states. In particular we show how electromagnetic transition form factors can emerge in a transport picture under the hypothesis of vector-meson dominance.

    The decay of hot and rotating {sup 172}Yb*, formed in two entrance channels {sup 124}Sn + {sup 48}Ca and {sup 132}Sn + {sup 40}Ca, is studied using the dynamical cluster-decay model. The effect of entrance channel, deformations (up to β{sub 2}), barrier modification and fusion enhancement are addressed. The decay pattern of compound system, formed in different channels at comparable energy around the barrier, shows change in magnitude with structure remains almost same. There is an increase in the fusion probability with decrease in barrier modification, which leads to fusion enhancement at low energies. The higher ℓ values are contributing for {sup 132}Sn + {sup 40}Ca channel at lower energies as compare to {sup 124}Sn + {sup 48}Ca. It is inferred that with the use of stable and radioactive beam, forming same compound nucleus, the entrance channel dependence changes with the excitation energy.

  8. Measurement of the ratio $B(t \\to W b)/B(t \\to W q)$ in $t\\bar{t}$ dilepton channel at CDF

    2012-01-01

    My analysis is based on the number of b-jets found in t¯t events using the dilepton sample with at least 2 jets in the final state. The charged leptons could be either electrons or muons. Tau leptons are not included. We use SecVtx algorithm, based on the reconstruction of a secondary vertex in the event, in order to identify a jet coming from b-quark fragmentation (b-tagging). Due to the high purity of the t¯t signal in dilepton events it is possible to perform a kinematic measurement of the t¯t cross section. Our strategy is to use this result to make prediction on the number of t¯t events. We divide our sample in subsets according to dilepton type (combination of the lepton type), number of jets in the final states and events with zero, one or two tags. The comparison between events and the prediction, given by the sum of the expected t¯t estimate and the background yield, in each subsample is made using a Likelihood function. Our measured value for R is the one which maximizes the Likelihood, i.e. gives the best match between our expectation and the observed data. We measure: p¯p!t¯t = 7.05±0.53stat±0.42lumi , R= 0.86±0.06 (stat+syst) and, in the hypothesis of CKM matrix unitarity with three quark generations, | Vtb | = 0.93 ± 0.03. Our analysis on the p¯p!t¯t was performed independently of the official dilepton analisys on the t¯t production cross section. So it represents also a valuable crosscheck for the official analysis. In chapter 1, a brief introduction to the theoretical framework is given. The standard model of elementary particles and the Quantum Cromodynamic theories are introduced. Then the top quark is presented, with a short descpription of its properties, as its mass, its production mode and its cross section. Some previous results on R are listed as well. Later we present the experiment that collected our data, both the collider (chapter 2) and the detector (CDF)(chapter 3). In chapter 4 we describe the physics object

    We present a measurement of the top-quark mass in events containing two leptons (electrons or muons) with a large transverse momentum, two or more energetic jets, and a transverse-momentum imbalance. We use the full proton-antiproton collision data set collected by the CDF experiment during the Fermilab Tevatron Run II at center-of-mass energy √{s }=1.96 TeV , corresponding to an integrated luminosity of 9.1 fb-1 . A special observable is exploited for an optimal reduction of the dominant systematic uncertainty, associated with the knowledge of the absolute energy of the hadronic jets. The distribution of this observable in the selected events is compared to simulated distributions of t t ¯ dilepton signal and background. We measure a value for the top-quark mass of 171.5 ±1.9 (stat)±2.5 (syst) GeV /c2 .

    At LHC energy, heavy quarks will be abundantly produced and the design of the ALICE Experiment will allow us to study their production using several channels. We investigate the feasibility of the study of D mesons reconstructed in their exclusive hadronic decay channel. After reviewing the ALICE potential for such studies, we will present some results for the two more promising decay channels i.e D0->KPi and D+ -> K-Pi+Pi+ obtained with 7 TeV pp data and 5.5 A TeV Pb-Pb Monte Carlo data .

    We report the most restrictive direct limits on masses of fourth-generation down-type quarks $b^{\\prime}$, and quark-like composite fermions ($B$ or $T_{5/3}$), decaying promptly to $t W^{\\mp}$. We search for a significant excess of events with two same-charge leptons ($e$, $\\mu$), several hadronic jets, and missing transverse energy. An analysis of data from $p\\overline{p}$ collisions with an integrated luminosity of 2.7 fb$^{-1}$ collected with the CDF II detector at Fermilab yields no evidence for such a signal, setting mass limits $m_{b^{\\prime}}, m_{B} >$ 338 $\\mathrm{GeV}/c^2$ and $m_{T_{5/3}} >$ 365 $\\mathrm{GeV}/c^2$ at 95% confidence level.

    Measurements of normalized differential cross-sections of top quark pair ($t\\bar t$) production are presented as a function of the mass, the transverse momentum and the rapidity of the $t\\bar t$ system in proton-proton collisions at center-of-mass energies of $\\sqrt{s}$ = 7 TeV and 8 TeV. The dataset corresponds to an integrated luminosity of 4.6 fb$^{-1}$ at 7 TeV and 20.2 fb$^{-1}$ at 8 TeV, recorded with the ATLAS detector at the Large Hadron Collider. Events with top quark pair signatures are selected in the dilepton final state, requiring exactly two charged leptons and at least two jets with at least one of the jets identified as likely to contain a $b$-hadron. The measured distributions are corrected for detector effects and selection efficiency to cross-sections at the parton level. The differential cross-sections are compared with different Monte Carlo generators and theoretical calculations of $t\\bar t$ production. The results are consistent with the majority of predictions in a wide kinematic ...

    We present a measurement of the top-quark mass in events containing two leptons (electrons or muons) with a large transverse momentum, two or more energetic jets, and a transverse-momentum imbalance. We use the full proton-antiproton collision data set collected by the CDF experiment during the Fermilab Tevatron Run II at center-of-mass energy √s = 1.96 TeV, corresponding to an integrated luminosity of 9.1 fb–1. A special observable is exploited for an optimal reduction of the dominant systematic uncertainty, associated with the knowledge of the absolute energy of the hadronic jets. The distribution of this observable in the selected events is compared to simulated distributions of tt¯ dilepton signal and background. We measure a value for the top-quark mass of 171.5±1.9 (stat)±2.5 (syst) GeV/c2.

    We present a measurement of the top-quark mass in events containing two leptons (electrons or muons) with a large transverse momentum, two or more energetic jets, and a transverse-momentum imbalance. We use the full proton-antiproton collision data set collected by the CDF experiment during the Fermilab Tevatron Run~II at center-of-mass energy $\\sqrt{s} = 1.96$ TeV, corresponding to an integrated luminosity of 9.1 fb$^{-1}$. A special observable is exploited for an optimal reduction of the dominant systematic uncertainty, associated with the knowledge of the absolute energy of the hadronic jets. The distribution of this observable in the selected events is compared to simulated distributions of ${t\\bar{t}}$ dilepton signal and background.We measure a value for the top-quark mass of $171.5\\pm 1.9~{\\rm (stat)}\\pm 2.5~{\\rm (syst)}$ GeV/$c^2$.

    We report a measurement of the top-quark mass M_{t} in the dilepton decay channel tt[over ] --> bl;{'+} nu_{l};{'}b[over ]l;{-}nu[over ]_{l}. Events are selected with a neural network which has been directly optimized for statistical precision in top-quark mass using neuroevolution, a technique modeled on biological evolution. The top-quark mass is extracted from per-event probability densities that are formed by the convolution of leading order matrix elements and detector resolution functions. The joint probability is the product of the probability densities from 344 candidate events in 2.0 fb;{-1} of pp[over ] collisions collected with the CDF II detector, yielding a measurement of M_{t} = 171.2 +/- 2.7(stat) +/- 2.9(syst) GeV / c;{2}.

    We report a measurement of the top-quark mass Mt in the dilepton decay channel t tmacr →bl'+νl' bmacr l-ν¯l. Events are selected with a neural network which has been directly optimized for statistical precision in top-quark mass using neuroevolution, a technique modeled on biological evolution. The top-quark mass is extracted from per-event probability densities that are formed by the convolution of leading order matrix elements and detector resolution functions. The joint probability is the product of the probability densities from 344 candidate events in 2.0fb-1 of p pmacr collisions collected with the CDF II detector, yielding a measurement of Mt=171.2±2.7(stat)±2.9(syst)GeV/c2.

    We propose a method for reconstructing the mass of a particle, such as the Higgs boson, decaying into a pair of {tau} leptons, of which one subsequently undergoes a 3-prong decay. The kinematics is solved using information from the visible decay products, the missing transverse momentum, and the 3-prong {tau} decay vertex, with the detector resolution taken into account using a likelihood method. The method is shown to give good discrimination between a 125 GeV Higgs boson signal and the dominant backgrounds, such as Z{sup 0} decays to {tau}{tau} and W{sup {+-}} plus jets production. As a result, we find an improvement, compared to existing methods for this channel, in the discovery potential, as well as in measurements of the Higgs boson mass and production cross section times branching ratio.

    The mass spectrum of c b ¯ states has been obtained using the phenomenological relativistic quark model (RQM) with coupled channel effects. The Hamiltonian used in the investigation has confinement potential and confined one gluon exchange potential (COGEP). In the frame work of the RQM, a study of magnetic dipole and electric dipole transitions and radiative decays of c b ¯ states has been made. The weak decay widths in the spectator quark approximation have been estimated. An overall agreement is obtained with the experimental masses and decay widths.

    At the tagged photon beam of the ELSA electron synchrotron at the University of Bonn in Germany the Crystal Barrel and TAPS photon spectrometers have been combined to provide a 4π detector for multi-neutral-particle final states from photonuclear reactions. In a series of experiments on single and multiple neutral meson emission we have concentrated on the hyperon production off the proton, and in particular on the K0Σ+ channel. High-quality excitation function, recoil polarizations, and angular distributions from the KΣ threshold up to 2.3 GeV c.m. energy were obtained. Particular care was taken to establish the cross section normalization. The experimental results are compared with predictions aof a recent coupled-channels calculation within the K-matrix formalism by A. Usov and O. Scholten1.

  5. Measurements of the Higgs Boson in the $H\\rightarrow\\tau\\tau$ Decay Channel

    The generation of vector boson mass via the Higgs mechanism in the Standard Model has been confirmed by the 2012 discovery of a candidate Higgs boson in the $H\\rightarrow{WW}$, $H\\rightarrow{ZZ}$, and $H\\rightarrow\\gamma\\gamma$ decay channels. In contrast, the Yukawa couplings hypothesized to provide the mass of fermions in the Standard Model have yet to be observed. The $H\\rightarrow\\tau\\tau$ decay channel currently provides the best opportunity for observing these couplings. This thesis describes two separate but related searches for Higgs boson decays in the $H\\rightarrow\\tau\\tau$ decay channel using proton-proton collisions recorded by the ATLAS detector. The first analysis is a general search for all Higgs boson production mechanisms leading to a $H\\rightarrow\\tau\\tau$ decay using 4.5 fb$^{-1}$ of 7 TeV and 20.3 fb$^{-1}$ of 8 TeV proton-proton collision data. A deviation from the background-only hypothesis is observed with a significance of $4.5\\sigma$ for a hypothetical Higgs boson mass of ${m_{H} ...

    The top quark pair production cross section is measured in dilepton events with one electron or muon, and one hadronically decaying tau lepton from the decay t anti-t to (l nu(l)) (tau nu(tau)) b anti-b, where l can be either an electron or a muon. The data sample corresponds to an integrated luminosity of 2.0 inverse femtobarns for the electron channel and 2.2 inverse femtobarns for the muon channel, collected by the CMS detector at the LHC. This is the first measurement of the t anti-t cross section explicitly including tau leptons in proton-proton collisions at sqrt(s)=7 TeV. The measured value sigma(t anti-t) = 143 +/- 14 (stat.) +/- 22 (syst.) +/- 3 (lumi.) pb is consistent with the standard model predictions.

    Four major approaches to the theoretical calculation of alpha decay widths were examined for light and heavy, even- and odd-mass nuclei. Application of the microscopic shell model rate theory as well as macroscopic models utilizing the coupled-channel formalism were studied. Use of the R-matrix and S-matrix theories have been applied in order to overcome problems involving dependency on the connection radius and nuclear potential parameters of the relative and absolute alpha decay widths. 105 references.

    After the discovery of a Higgs-like Boson with a mass close to 125 GeV at the LHC in summer 2012, we are showing the update on the analysis of the VH cannel. In this channel the Higgs-like Boson is produced in association with a vector boson and decaying into b quarks. We present the updated results on the full 2011 and 2012 7+8 TeV dataset. This poster will focus on one of the tree modes that are combined in this analysis, where the associated vector boson is a Z boson that is decaying leptonically into two electrons or muons, respectively.

    The most recent analysis of dilepton spectra, produced in heavy ion collisions, have shown the need for a precise knowledge of all dilepton production channels. The experimental HADES facility, installed on the GSI accelerator site, is appropriate for that goal. Thus, the Dalitz decay branching ratio of {delta} resonance ({delta} {yields} Ne{sup +}e{sup -}), which has never been measured, is studied in this work. Moreover, the pp {yields} p/ {delta}{sup +} {yields} ppe{sup +-} reaction could allow to provide some information about the internal resonance structure and more precisely, about the electromagnetic transition N - A form factors. The analysis of simulations shows the feasibility of this experiment, estimates the counting yield as well as the Signal over Background ratio. This analysis shows also the great importance of the momentum resolution of the detector for the success of this experiment. The momentum resolution must be investigated. In this work, an attempt to find out the most important contributions to the measured resolution is presented. The calibration step, which provides the relation between electronic time and physical time, the detector alignment (global, relative or internal) as well as the tracking method are studied. Some methods for improvement of these different contributions are proposed in order to reach the optimal resolution. (author)

  13. Coupled-channel Dalitz plot analysis of $D^+\\to K^- \\pi^+\\pi^+$ decay

    Nakamura, Satoshi X

    2016-01-01

    We demonstrate that partial wave amplitudes extracted from $D^+\\to K^-\\pi^+\\pi^+$ Dalitz plot with a unitary coupled-channel model are significantly different from those obtained with an isobar model. The unitary coupled-channel model takes account of hadronic rescattering mechanisms involving all three mesons that have been missed in conventioanl isobar model analyses. The rescattering mechanisms contribute largely, and can triplicate the $D^+\\to {K}^-\\pi^+\\pi^+$ decay width within our analysis. These findings deliver a warning that analysis results obtained with isobar models should be looked with a caution. The determination of the CKM angle $\\gamma/\\phi_3$ is a highly relevant problem.

    The dispersive approach to QCD, which extends the applicability range of perturbation theory towards the infrared domain, is developed. This approach properly accounts for the intrinsically nonperturbative constraints, which originate in the low-energy kinematic restrictions on pertinent strong interaction processes. The dispersive approach proves to be capable of describing OPAL (update 2012) and ALEPH (update 2014) experimental data on inclusive tau lepton hadronic decay in vector and axial-vector channels in a self-consistent way.

    Recent results on searches for Beyond Standard Model production of Higgsbosons in fermion decay channels are presented. The analyses are based on proton-proton collision data recorded by the CMS experiment at 7, 8, and 13 TeV centre-of-mass energies. The exclusion limits determined by the null results of the searches are interpreted in the framework of models that include extensions of the standard Higgs sector.

    Prospects of discovering and identifying effects of extra spatial dimensions in dilepton and diphoton production at the Large Hadron Collider (LHC) are studied. Such effects may be revealed by the characteristic behavior of the invariant-mass distributions of dileptons and diphotons, and their identification can be performed on the basis of an analysis of their angular distributions. The discovery and identification reaches are estimated for the scale parameter M{sub S} of the Kaluza-Klein gravitational towers, which can be determined in experiments devoted to measuring the dilepton and diphoton channels at the LHC.

    The ATLAS detector at the Large Hadron Collider is used to search for high-mass resonances decaying to an electron-positron pair or a muon-antimuon pair. The search is sensitive to heavy neutral Z' gauge bosons, Randall-Sundrum gravitons, Z* bosons, techni-mesons, Kaluza-Klein Z/gamma bosons, and bosons predicted by Torsion models. Results are presented based on an analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 4.9/fb in the dielectron channel and 5.0/fb in the dimuon channel. A Z' boson with Standard Model-like couplings is excluded at 95 percent confidence level for masses below 2.22 TeV. A Randall-Sundrum graviton with coupling k/Mbar = 0.1 is excluded at 95 percent confidence level for masses below 2.16 TeV. Limits on the other models are also presented, including Technicolor and Minimal Z' Models.

    The top-quark mass is measured in proton-proton collisions at $\\sqrt{s}$ = 7 TeV using a data sample corresponding to an integrated luminosity of 5.0 inverse femtobarns collected by the CMS experiment at the LHC. The measurement is performed in the dilepton decay channel $t\\bar{t}$ to ell+ nu[ell] b, ell- anti-nu[ell] b-bar, where ell=e,$\\mu$. Candidate top-quark decays are selected by requiring two leptons, at least two jets, and imbalance in transverse momentum. The mass is reconstructed with an analytical matrix weighting technique using distributions derived from simulated samples. Using a maximum-likelihood fit, the top-quark mass is determined to be 172.5 +/- 0.4 (stat) +/- 1.5 (syst) GeV.

    The top-quark mass is measured in proton-proton collisions at sqrt{s} = 7 {TeV} using a data sample corresponding to an integrated luminosity of 5.0 fb-1 collected by the CMS experiment at the LHC. The measurement is performed in the dilepton decay channel toverline{t}rightarrow(ell+ν_{ell}b) (ell-overline{ν}_{ell}overline{b}), where ℓ=e, μ. Candidate top-quark decays are selected by requiring two leptons, at least two jets, and imbalance in transverse momentum. The mass is reconstructed with an analytical matrix weighting technique using distributions derived from simulated samples. Using a maximum-likelihood fit, the top-quark mass is determined to be 172.5±0.4 (stat.)±1.5 (syst.) GeV.

    Many well established models extending beyond Standard Model (e.g. Grand Unified Theory, Sequential Standard Model or models proposing extra spatial dimension(s)) predict the existence of new heavy neutral bosons that would decay in two leptons. A search for new narrow resonances, generically referred as Z, in the dilepton decay channel has been performed using data collected by the CMS experiment in 2016 from proton - proton collisions at a center of mass energy of $\\sqrt{s}$ = 13 TeV corresponding to an integrated luminosity of 13 fb$^{-1}$. In the absence of a significant deviation from the standard model predictions, 95\\% confidence level limits are set on the ratio of the production cross section times branching fraction for high-mass resonances to that for the Z boson. For several models, lower limits on the resonance mass are derived.

    Results are reported from a search for the top squark $ \\tilde{t}_1 $, the lighter of the two supersymmetric partners of the top quark. The data sample corresponds to 19.7 fb$^{-1}$ of proton-proton collisions at $\\sqrt{s} =$ 8 TeV collected with the CMS detector at the LHC. The search targets $ \\tilde{t}_1 \\to \\mathrm{b} \\tilde{\\chi}^{\\pm}_1$ and $ \\tilde{t}_1 \\to \\mathrm{t}^{(*)} \\tilde{\\chi}^0_1$ decay modes, where $\\tilde{\\chi}^{\\pm}_1$ and $\\tilde{\\chi}^0_1$ are the lightest chargino and neutralino, respectively. The reconstructed final state consists of jets, b jets, missing transverse energy, and either one or two leptons. Leading backgrounds are determined from data. No significant excess in data is observed above the expectation from standard model processes. The results exclude a region of the two-dimensional plane of possible $ \\tilde{t}_1 $ and $\\tilde{\\chi}^0_1 $ masses. The highest excluded $ \\tilde{t}_1 $ and $ \\tilde{\\chi}^0_1$ masses are about 700 GeV and 250 GeV, respectively.

    We show that within the left-right symmetric model, lepton number violating decays of the Higgs boson can be discovered at the LHC. The process is due to the mixing of the Higgs boson with the triplet that breaks parity. As a result, the Higgs boson can act as a gateway to the origin of the heavy Majorana neutrino mass. To assess the LHC reach, a detailed collider study of the same-sign dileptons plus jets channel is provided. This process is complementary to the existing nuclear and collider searches for lepton number violation and can probe the scale of parity restoration even beyond other direct searches.

    The results of background measurements with the second version of the BOREXINO Counting Test Facility (CTF-II), installed in the Gran Sasso Underground Laboratory, were used to obtain limits on the instability of nucleons, bounded in nuclei, for decays into invisible channels (inv): disappearance, decays to neutrinos, etc. The approach consisted of a search for decays of unstable nuclides resulting from N and NN decays of parent ^{12}C, ^{13}C and ^{16}C nuclei in the liquid scintillator and the water shield of the CTF. Due to the extremely low background and the large mass (4.2 ton) of the CTF detector, the most stringent (or competitive) up-to-date experimental bounds have been established: \\tau(n\\to inv)>1.8\\cdot 10^{25} y, \\tau(p\\to inv)>1.1\\cdot 10^{26} y, \\tau(nn\\to inv)>4.9\\cdot 10^{25} y and \\tau(pp\\to inv)>5.0\\cdot 10^{25}y (all at 90 % C. L.).

    Analyses of the J/ψπ+π- decay channel of the X(3872) resonance by the CDF, Belle, and LHCb Collaborations have established its JPC quantum numbers as 1++. An analysis of the π+π-π0 invariant mass distribution in the J/ψπ+π-π0 decay channel by the BABAR Collaboration indicated a preference for 2-+ over 1++. We point out that a proper evaluation of the χ2 in that analysis increases the probability for 1++ from 7.1% to about 18.7%. In the case of quantum numbers 1++, where the X has an S-wave coupling to J/ψω, the proximity of the J/ψω threshold to D*D¯ thresholds and the narrow width of the ω suggest that the effects of scattering between J/ψω and charm meson pairs could be significant. We derive invariant mass distributions for J/ψπ+π-π0 and π+π-π0 that take into account S-wave scattering between the D*0D¯0, D*+D-, and J/ψω channels. We also analyze the effects of scattering through the χc1(2P) charmonium resonance. We find that scattering effects are unable to produce significant changes in the shape of the π+π-π0 invariant mass distribution.

    Using the QCD sum rule approach we study the Y(4140) state assuming that it can be described by a Ds* Ds* molecular state with JPC =0++ quantum numbers. We evaluate the decay width into the channel Y → J / ψϕ and we find the value Γ Y → J / ψϕ ≃ (0.34 ± 0.11) MeV, which is much smaller than the total experimental width Γ ≃ (20 ± 8) MeV. However, considering the experimental upper limits for the decay of the Y(4140) into di-photons, Γγγ × B [Γ Y → J / ψϕ ] < 41 eV, such a scalar molecule can be a good candidate to explain the possible exotic structure of the Y(4140) state.

    A search is performed for heavy resonances decaying to two long-lived massive neutral particles, each decaying to leptons. The experimental signature is a distinctive topology consisting of a pair of oppositely charged leptons originating at a separated secondary vertex. Events were collected by the CMS detector at the LHC during pp collisions at $\\sqrt{s}$ = 7 TeV, and selected from data samples corresponding to 4.1 (5.1) inverse femtobarns of integrated luminosity in the electron (muon) channel. No significant excess is observed above standard model expectations, and an upper limit is set with 95% confidence level on the production cross section times the branching fraction to leptons, as a function of the long-lived massive neutral particle lifetime.

    A search for narrow resonances at high mass in the dimuon and dielectron channels has been performed by the CMS experiment at the CERN LHC, using pp collision data recorded at $\\sqrt{s}$=7 TeV. The event samples correspond to integrated luminosities of 40 inverse picobarns in the dimuon channel and 35 inverse picobarns in the dielectron channel. Heavy dilepton resonances are predicted in theoretical models with extra gauge bosons (Z') or as Kaluza-Klein graviton excitations($G_{KK}$) in the Randall-Sundrum model. Upper limits on the inclusive cross section of Z'($G_{KK}$) decaying to oppositely charged leptons relative to Z decaying to oppositely charged leptons are presented. These limits exclude at 95% confidence level a Z' with standard-model-like couplings below 1140 GeV, the superstring-inspired $Z'_\\psi$ below 887 GeV, and, for values of the coupling parameter $k/\\bar{M}_{Pl}$ of 0.05 (0.1), Kaluza-Klein gravitons below 855 (1079) GeV.

    The first observation of BzBaz mixing from the study of Υ(4S) decays with two leptons in 1987 by the ARGUS experiment at the e^+ e^- storage ring DORIS II at DESY/Hamburg(Germany) is discussed. The effect of BzBaz mixing lead to the appearance of events with fast like-signed dileptons. Despite some backgroundcontamination such events provided the most statistically significant measurement of the strength of the mixing parameter. The current experimental situation in BzBaz mixing is also discussed. note

    2016-01-01

    Dilepton production in heavy-ion collisions at various energies is studied using coarse-grained transport simulations. Microscopic output from the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model is hereby put on a grid of space-time cells which allows to extract the local temperature and chemical potential in each cell via an equation of state. The dilepton emission is then calculated applying in-medium spectral functions from hadronic many-body theory and partonic production rates based on lattice calculations. The comparison of the resulting spectra with experimental data shows that the dilepton excess beyond the decay contributions from a hadronic cocktail reflects the trajectory of the fireball in the $T-\\mu_{\\mathrm{B}}$ plane of the QCD phase diagram.

    We present a fully differential next-to-next-to-leading-order calculation of t -channel single top quark production and decay at the LHC under a narrow-width approximation and neglecting cross talk between incoming protons. We focus on the fiducial cross sections at 13 TeV, finding that the next-to-next-to-leading-order QCD corrections can reach the level of -6 %. The scale variations are reduced to the level of a percent. Our results can be used to improve experimental acceptance estimates and the measurements of the single top quark production cross section and the top quark electroweak couplings.

  11. Dilepton Spectroscopy of QCD Matter at Collider Energies

    2013-01-01

    Full Text Available Low-mass dilepton spectra as measured in high-energy heavy-ion collisions are a unique tool to obtain spectroscopic information about the strongly interacting medium produced in these reactions. Specifically, in-medium modifications of the vector spectral function, which is well known in the vacuum, can be deduced from the thermal radiation off the expanding QCD fireball. This, in particular, allows to investigate the fate of the ρ resonance in the dense medium and possibly infer from it signatures of the (partial restoration of chiral symmetry, which is spontaneously broken in the QCD vacuum. After briefly reviewing calculations of thermal dilepton emission rates from hot QCD matter, utilizing effective hadronic theory, lattice QCD, or resummed perturbative QCD, we focus on applications to dilepton spectra at heavy-ion collider experiments at RHIC and LHC. This includes invariant-mass spectra at full RHIC energy with transverse-momentum dependencies and azimuthal asymmetries, as well as a systematic investigation of the excitation function down to fixed-target energies, thus making contact to previous precision measurements at the SPS. Furthermore, predictions for the energy frontier at the LHC are presented in both dielectron and dimuon channels.

    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.

  13. Measurements of the Top Anti-Top Production Cross Section and Top Quark Mass in the Hadronically Decaying Tau + Jets Decay Channel at CDF

    In this thesis, we present the first exclusive observation of the t-t → hadronic τ + jets decay channel. Using these events, we measure the t-t pair production cross section and the top quark mass in 2.2 fb-1 of data collected with the Collider Detector at Fermilab (CDF). The Tevatron accelerator at Fermilab provides collisions of protons and anti-protons at a center-of-mass energy of √s = 1.96 TeV and is one of only two accelerators in the world with enough energy to produce top quarks. With a branching fraction of nearly 10%, the hadronic τ + jets decay channel is the third largest t-t decay mode, and it has only been minimally explored. This the first measurement of the t-t pair production cross section in this decay channel at CDF and the first measurement of the top quark mass in this decay channel in the world. The analysis introduces a new method to recover the total momentum of the ν produced in the τ decay and an artificial neural network to reduce the contribution from the largest background source, QCD multijet background. The t-t pair production cross section is extracted by minimizing a negative log likelihood function which compares the number of observed events to the number of expected events for a given t-t cross section. The top quark mass is extracted by minimizing a negative log likelihood function built from signal and ii background probabilities which are based on the matrix elements for t-t production and decay and W + 4 parton production, respectively. Using events selected with exactly 1 hadronically decaying τ, exactly 4 jets with at least 1 identified as having originated from a b quark, and large missing transverse energy, we measure the t-t pair production cross section to be 8.8 ± 3.3 (stat.) ± 2.2 (syst.) pb and the top quark mass to be 172.7±9.3 (stat.) ±3.7 (syst.) GeV. We find both values to be in good agreement with

  14. Mechanism of accelerated current decay caused by an episodic ataxia type-1-associated mutant in a potassium channel pore.

    In Kv1.1, single point mutants found below the channel activation gate at residue V408 are associated with human episodic ataxia type-1, and impair channel function by accelerating decay of outward current during periods of membrane depolarization and channel opening. This decay is usually attributed to C-type inactivation, but here we provide evidence that this is not the case. Using voltage-clamp fluorimetry in Xenopus oocytes, and single-channel patch clamp in mouse ltk- cells, of the homologous Shaker channel (with the equivalent mutation V478A), we have determined that the mutation may cause current decay through a local effect at the activation gate, by destabilizing channel opening. We demonstrate that the effect of the mutant is similar to that of trapped 4-aminopyridine in antagonizing channel opening, as the mutation and 10 mm 4-AP had similar, nonadditive effects on fluorescence recorded from the voltage-sensitive S4 helix. We propose a model where the Kv1.1 activation gate fails to enter a stabilized open conformation, from which the channel would normally C-type inactivate. Instead, the lower pore lining helix is able to enter an activated-not-open conformation during depolarization. These results provide an understanding of the molecular etiology underlying episodic ataxia type-1 due to V408A, as well as biophysical insights into the links between the potassium channel activation gate, the voltage sensor and the selectivity filter.

    A search is presented for heavy-quark pair production (QQbar) under the decay hypothesis QQbar to WqWq with q = u,d,c,s,b. The search is performed with 1.04 fb^-1 of integrated luminosity from pp collisions at sqrt(s) = 7 TeV collected by the ATLAS detector at the CERN LHC. Dilepton final states are selected, requiring large missing transverse momentum and at least two jets. Mass reconstruction of heavy quark candidates is performed by assuming that the W boson decay products are nearly collinear. The data are in agreement with Standard Model expectations; a heavy quark with mass less than 350 GeV is excluded at 95% confidence level.

    Study of the production of pairs of top quarks in association with a Higgs boson is one of the primary goals of the Large Hadron Collider over the next decade, as measurements of this process may help us to understand whether the uniquely large mass of the top quark plays a special role in electroweak symmetry breaking. Higgs bosons decay predominantly to bbar b, yielding signatures for the signal that are similar to tbar t + jets with heavy flavor. Though particularly challenging to study due to the similar kinematics between signal and background events, such final states (tbar t bbar b) are an important channel for studying the top quark Yukawa coupling. This paper presents a systematic study of machine learning (ML) methods for detecting tbar th in the h → bbar b decay channel. Among the eight ML methods tested, we show that two models, extreme gradient boosted trees and neural network models, outperform alternative methods. We further study the effectiveness of ML algorithms by investigating the impact of feature set and data size, as well as the structure of the models. While extended feature set and larger training sets expectedly lead to improvement of performance, shallow models deliver comparable or better performance than their deeper counterparts. Our study suggests that ensembles of trees and neurons, not necessarily deep, work effectively for the problem of tbar th detection.

  18. Semihadronic and hadronic decays of ρ0 and ω mesons coherently photoproduced in isoscalar nuclei

    The interference of ρ0 and ω mesons has been studied in the hadronic and leptonic decay channels, i.e., dipion and dilepton decay channels respectively, but this interference has not been studied yet in the semihadronic or semileptonic decay channel, e.g., V →π0γ . V denotes either a ρ0 or ω meson. To look for this interference in the π0γ decay channel as well as the contribution of the ρ meson to the cross section, the correlated π0γ invariant mass distribution spectra are calculated in the photonuclear reaction in the multi-GeV region. It is assumed that these bosons arise in the final state due to the decay of ρ0 and ω mesons which are photoproduced coherently in the isoscalar nucleus. The elementary reaction in the nucleus is considered to proceed as γ N →V N , V →π0γ . The forward propagation of the ρ and ω mesons and the near forward emission of pions are considered, so that they can be described by the eikonal form. The meson-nucleus interactions are evaluated using the t ϱ approximation. Replacing the decay vertex V →π0γ by V →π+π- in the above formalism, it is also used to study the ρ -ω interference in the π+π- decay channel.

    The start of proton-proton collisions at the LHC inaugurates a new era in high-energy physics. It enables the possibility of discoveries at the high-energy frontier and also allows for studies of known Standard Model processes with unrivalled precision. Top quark pairs are produced at high rates and allow for precision measurements of the properties of the top quark with high statistics. The measurement of the top quark pair production cross section in proton-proton collisions at {radical}(s)=7 TeV is presented using the dileptonic decay channel with a muon-electron pair in the final state. The data sample, which is used in this analysis, corresponds the complete 2010 data taking period with an integrated luminosity of 35.9 pb{sup -1}. Top quark pair candidate events are selected in a cut-based event selection. Based on 59 observed muon-electron events in the final state event sample, the top quark pair production cross section is measured to be {sigma}{sub t} {sub anti} {sub t}=(156{+-}25(stat.){+-}14(sys.)) pb. Furthermore, a kinematic event reconstruction is applied, which is complementary to the use of b-tagging techniques, and validates the top quark-like topology of the selected events. First results from the measurement of differential cross sections based on the data from the complete 2010 data taking period are presented. For the first time in the CMS collaboration, the cross section of the production of top quark pairs is measured differentially as a function of the kinematic observables of the final state objects, such as the transverse momentum p{sub T} of the leptons and the invariant mass of the lepton pair. Based on the solution of the kinematic event reconstruction, the cross section is also calculated differentially as a function of the kinematic properties of the reconstructed top-antitop quark pair. First results from the measurement of differential cross sections as a function of the kinematics of the final state leptons are presented, using the

    In the Standard Model (SM) the top quark mass is a fundamental parameter. Its precise measurement is important to test the self-consistency of the SM. Additionally, it offers sensitivity to New Physics beyond the Standard Model. In proton anti-proton collisions at a centre-of-mass energy of {radical}s = 1.96 TeV t{bar t} quarks are pair-produced, each decaying into a W boson and a b quark. In the dilepton channel both W bosons decay leptonically. Because of the presence of two neutrinos in the final state the kinematics are underconstrained. A so-called Neutrino Weighting algorithm is used to calculate a weight for the consistency of a hypothesized top quark mass with the event kinematics. To render the problem solvable, the pseudorapidities of the neutrinos are assumed. The Maximum Method, which takes the maximum to the weight distribution as input to infer the top quark mass, is applied to approximately 370 pb{sup -1} of Run-II data, recorded by the D0 experiment at the Tevatron. The e{mu}-channel of the 835 pb{sup -1} dataset is analyzed.

    The coupling properties of the Higgs boson are studied in the diphoton, ZZ to four-lepton decay channels using 36.1 fb$^{-1}$ of $pp$ collision data from the LHC at a centre-of-mass energy of 13 TeV collected by the ATLAS detector. Measurements of simplified template cross sections, designed to measure the different Higgs boson production processes in specific regions of phase space, are reported for diphoton and four-leptons decay channels. Cross sections for different higgs boson production modes are interpreted in terms of coupling modifiers. In ZZ decay channel, the tensor structure of the Higgs boson couplings is studied using an effective Lagrangian approach for the description of interactions beyond the Standard Model.

    The Lamb shift (self-energy) of an elliptic dielectric microcavity is studied. We show that the size of the Lamb shift, which is a small energy shift due to the system-environment coupling in the quantum regime, is dependent on the geometry of the boundary conditions. It shows a global transition depending on the eccentricity of the ellipsis. These transitions can be classified into three types of decay channels known as whispering-gallery modes, stable-bouncing-ball modes, and unstable-bouncing-ball modes. These modes are manifested through the Poincaré surface of section with the Husimi distribution function in classical phase space. It is found that the similarity (measured in Bhattacharyya distance) between the Husimi distributions below critical lines of two different modes increases as the difference of their self-energies decreases when the quality factors of the modes are on the same order of magnitude.

    After the discovery of the Higgs boson, the precision measurements of its properties and comparison of results to those predicted by the Standard Model (SM) became the crucial part of the LHC physics programme. Potential observation of deviations may lead to the discovery of a new physics beyond the Standard Model (BSM). In this contribution, the results of analyses of the Higgs boson properties in H->ZZ*->4l decay channel are presented. The measurements of Higgs SM couplings, fiducial and differential cross sections with 36.1 fb -1 of data collected by ATLAS at sqrt s = 13 TeV are shown. The observed limits on BSM tensor structure of Higgs couplings to SM bosons and fermions are also discussed.

    2016-01-01

    We present a search for direct top squark production in the opposite-sign dilepton channel using LHC pp collision data at $\\sqrt{s}=13~\\mathrm{TeV}$ amounting to $12.9~\\mathrm{fb}^{-1}$ collected by the CMS detector in 2016. The search is performed in final states with two leptons, electrons or muons, jets, of which at least one is b-tagged, and missing transverse momentum. Signal regions are defined using transverse mass variables, which efficiently separate the signal from the dominant top-quark pair background. No significant deviation from the background prediction is observed. Exclusion limits are set in the context of a simplified supersymmetric model with pair production of top squarks that each decay to a top quark and a neutralino. For neutralino masses below $150~\\mathrm{GeV}$, masses of the lightest top squark below $650~\\mathrm{GeV}$ are excluded at a confidence level of $95\\%$.

    A search is conducted for non-resonant new phenomena in dielectron and dimuon final states, originating from either contact interactions or large extra spatial dimensions. The LHC 2012 proton--proton collision dataset recorded by the ATLAS detector is used, corresponding to 20~fb$^{-1}$ at $\\sqrt{s}$ = 8 TeV. The dilepton invariant mass spectrum is a discriminating variable in both searches, with the contact interaction search additionally utilizing the dilepton forward-backward asymmetry. No significant deviations from the Standard Model expectation are observed. Lower limits are set on the new physics parameters of interest at the 95% credibility level. For $\\ell\\ell q q$ contact interactions, lower limits are set on the contact interaction scale $\\Lambda$ between 15.4 TeV and 26.3 TeV. Lower limits are also set on the string scale $M_{\\rm S}$ for large extra spatial dimensions, from 4.1 TeV to 6.1 TeV.

    2002-01-01

    We consider dilepton production in high energy proton-nucleus (and very forward nucleus-nucleus) collisions. Treating the target nucleus as a Color Glass Condensate and describing the projectile proton (nucleus) as a collection of quarks and gluons as in the parton model, we calculate the differential cross section for dilepton production in quark-nucleus scattering and show that it is very sensitive to the saturation scale characterizing the target nucleus.

    2016-01-01

    Measurements of Higgs boson properties using the Hâ??ZZâ??4l (l = e, μ) decay channel are presented, based on a data sample corresponding to an integrated luminosity of 12.9 fbâ??1 of pp collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC during 2016. The observed significance for the standard model Higgs boson is 6.2Ï? at a mass of mH = 125.09 GeV, where the expected significance is 6.5Ï?. The signal strength μ, defined as the ratio of the Higgs boson production cross section times branching fraction to four leptons to the standard model expectation, is measured to be μ = 0.99 +0.33â??0.26. Individual strength parameters for four Higgs boson production modes are constrained for the first time using this channel. The Higgs boson mass is measured to be mH = 124.50 +0.48â??0.46 GeV. The model-independent fiducial cross section is measured to be 2.29 +0.74â??0.64(stat.) +0.30â??0.23(sys.) +0.01â??0.05(model dep.) fb, and differential cross sections as a f...

  10. Photon and dilepton spectra from nonlinear QED effects in supercritical magnetic fields induced by heavy-ion collisions

    CERN Document Server

    Hattori, Koichi

    2015-01-01

    We discuss properties of photons in extremely strong magnetic fields induced by the relativistic heavy-ion collisions. We investigate the vacuum birefringence, the real-photon decay, and the photon splitting which are all forbidden in the ordinary vacuum, but become possible in strong magnetic fields. These effects potentially give rise to anisotropies in photon and dilepton spectra.

    Top-quark physics is one of the main fields of investigation at the Tevatron accelerator and, ultimately, at the LHC. We perform a phenomenological analysis of t anti t events at hadron colliders, with a focus on observables relying on bottom-quark fragmentation in top-quark decay. In particular, we investigate the B-lepton invariant-mass distribution in the dilepton channel and give an estimate of the contribution of bottom fragmentation to the Monte Carlo uncertainty on the top-quark mass reconstruction.

  13. Skyrme forces and decay of the Rf266*104 nucleus synthesized via different incoming channels

    2017-03-01

    The excitation functions for the production of 262Rf, 261Rf, and 260Rf isotopes via 4 n -, 5 n -, and 6 n -decay channels from the *266Rf compound nucleus are studied within the dynamical cluster-decay model (DCM), including deformations β2 i and so-called hot-optimum orientations θi which support symmetric fission, in agreement with experiments. The data are available for 18O+248Cm and 22Ne+244Pu reactions, respectively, at the energy ranges of Elab=88.2 to 101.3 and 109.0 to 124.8 MeV. For the nuclear interaction potentials, we use the Skyrme energy density functional (SEDF) based on semiclassical extended Thomas Fermi (ETF) approach, which means an extension of the earlier study of excitation functions of *266Rf formed in 18O+248Cm reaction, based on the DCM using the pocket formula for nuclear proximity potential, showing interaction dependence. The Skyrme forces used here are the old SIII and SIV and new GSkI and KDE0(v1) given for both normal and isospin-rich nuclei, with densities added in frozen density approximation. Interestingly, the DCM gives an excellent fit to the measured data on fusion evaporation residue (ER) for both the incoming channels (18O+248Cm and 22Ne+244Pu ) at the energy range Elab=88.2 to 124.8 MeV, independent of the entrance channel and Skyrme force used. The possible fusion-fission (ff) and quasifission (qf) mass regions of fragments on DCM are also predicted. The DCM with Skyrme forces is further used to look for all the possible target-projectile (t-p) combinations forming the cold compound nucleus (CN) *266Rf at the CN excitation energy of Elab for hot compact configurations. The fusion evaporation residue cross sections, for the proposed new reactions in synthesizing the CN *266Rf, are also estimated for the future experiments, and role of mass asymmetry of nuclei is indicated.

  16. Comparison of the coupled-channel calculation with the WKB method for α-decay fine structure

    Science.gov (United States)

    Ni, Dongdong; Ren, Zhongzhou

    2013-05-01

    The α-decay fine structures in heavy deformed even-even and odd-mass nuclei are investigated using the newly developed multichannel cluster model (MCCM) and the WKB barrier penetration formalism. The MCCM is based on the coupled-channel Schrödinger equation with outgoing wave boundary conditions. For even-even nuclei, the two methods yield comparable results concerning the branching ratios for 0+ and 2+ states but the WKB formula fails in reproducing the branching ratios for excited 4+ states. For odd-mass nuclei, it is hard to use the WKB formula to interpret the unexpected behavior BRI+1 >BRI while the MCCM succeeds. These emphasize that the coupling effects of decay channels cannot be ignored in describing the α-decay fine structure.

    Bottom production is investigated as a possible mechanism for same-sign prompt dileptons in neutrino reactions. A partonlike model is able to account for the CDHS dilepton signal with inputs compatible with other data.

    The total cross section, the intermediate mass fragment (IMF) production cross section, and the cross section for the formation of light particles (LPs) for the decay of compound system *56Ni formed through the entrance channel 32S+24Mg have been evaluated by taking the scattering potential as the sum of deformed Coulomb and deformed nuclear proximity potentials, for various Ec .m . values. The computed results have been compared with the available experimental data of total cross section corresponding to Ec .m .=60.5 and 51.6 MeV for the entrance channel 32S+24Mg , which were found to be in good agreement. The experimental values for the LP production cross section and IMF cross section for the channel 32S+24Mg were also found to agree with our calculations. Hence we have extended our studies and have thus computed the total cross section, IMF cross section, and LP cross section for the decay of *56Ni formed through the other three entrance channels 36Ar+20Ne,40Ca+16O , and 28Si+28Si with different Ec .m . values. Hence, we hope that our predictions on the evaluations of the IMF cross sections and the LP cross sections for the decay of *56Ni formed through these three channels can be used for further experimental studies.

    A set of exclusive decay of the Higgs boson into a vector meson and a dilepton pair (h → Vℓ+ ℓ-, with V = ϒ, J/ψ, ϕ, and ℓ = μ, τ) are studied in the framework of the Standard Model. We have evaluated the decay rates, the dilepton mass spectra and the V longitudinal helicity fraction distributions. In the same framework, we considered the exclusive modes h → Vvv¯ and the implications of the CMS and ATLAS results for the lepton flavor-changing process h → τ+ μ- on the h → Vτ+ μ- decay modes.

    Within the context of vector mediators, is a new signal observed in flavor changing interactions, particularly in the neutral mesons systems K0 -Kbar0, D0 -Dbar0 and B0 -B0 bar , consistent with dilepton resonance searches at the LHC? In the attempt to address this very simple question, we discuss the complementarity between flavor changing neutral current (FCNC) and dilepton resonance searches at the LHC run 2 at 13 TeV with 3.2 fb-1 of integrated luminosity, in the context of vector mediators at tree level. Vector mediators, are often studied in the flavor changing framework, specially in the light of the recent LHCb anomaly observed at the rare B decay. However, the existence of stringent dilepton bound severely constrains flavor changing interactions, due to restrictive limits on the Z‧ mass. We discuss this interplay explicitly in the well motivated framework of a 3-3-1 scheme, where fermions and scalars are arranged in the fundamental representation of the weak SU(3) gauge group. Due to the paucity of relevant parameters, we conclude that dilepton data leave little room for a possible new physics signal stemming from these systems, unless a very peculiar texture parametrization is used in the diagonalization of the CKM matrix. In other words, if a signal is observed in such flavor changing interactions, it unlikely comes from a 3-3-1 model.

  2. High-p_T dilepton tails and flavor physics

    We investigate the impact of flavor-conserving, non-universal quark-lepton contact interactions on the dilepton invariant mass distribution in p p → ℓ ^+ ℓ ^- processes at the LHC. After recasting the recent ATLAS search performed at 13 TeV with 36.1 fb^{-1} of data, we derive the best up-to-date limits on the full set of 36 chirality-conserving four-fermion operators contributing to the processes and estimate the sensitivity achievable at the HL-LHC. We discuss how these high-p_T measurements can provide complementary information to the low-p_T rare meson decays. In particular, we find that the recent hints on lepton-flavor universality violation in b → s μ ^+ μ ^- transitions are already in mild tension with the dimuon spectrum at high-p_T if the flavor structure follows minimal flavor violation. Even if the mass scale of new physics is well beyond the kinematical reach for on-shell production, the signal in the high-p_T dilepton tail might still be observed, a fact that has been often overlooked in the present literature. In scenarios where new physics couples predominantly to third generation quarks, instead, the HL-LHC phase is necessary in order to provide valuable information.

This decay mode is dominated by the {bar K}*(892){sup 0} contribution. We determine the {bar K}*(892){sup 0} parameters: m{sub K*(892){sup 0}} = (895.4{+-}0.2{+-}0.2) MeV/c{sup 2}, {Lambda}{sub K*(892){sup 0}}{sup 0} = (46.5{+-}0.3{+-}0.2) MeV/c{sup 2} and the Blatt-Weisskopf parameter r{sub BW} = 2.1{+-}0.5{+-}0.5 (GeV/c){sup -1} where the first uncertainty comes from statistics and the second from systematic uncertainties. We also measure the parameters defining the corresponding hadronic form factors at q{sup 2} = 0 (r{sub V} = V(0)/A{sub 1}(0) = 1.463{+-}0.017{+-}0.031, r{sup 2} = A{sub 2}(0)/A{sub 1}(0) = 0.801{+-}0.020{+-}0.020) and the value of the axial-vector pole mass parameterizing the q{sup 2} variation of A{sub 1} and A{sub 2}: m{sub A} = (2.63{+-}0.10{+-}0.13) GeV/c{sup 2}. The S-wave fraction is equal to (5.79{+-}0.16{+-}0.15)%. Other signal components correspond to fractions below 1%. Using the D{sup +} {yields} K{sup -}{pi}{sup +}{pi}{sup +} channel as a normalization, we measure the D{sup +} semileptonic branching fraction: {Beta}(D{sup +} {yields} K{sup -}{pi}{sup +}e{sup +}{nu}{sub e}) = (4.00 {+-} 0.03 {+-} 0.04 {+-} 0.09) x 10{sup -2} where the third uncertainty comes from external inputs. We then obtain the value of the hadronic form factor A{sub 1} at q{sup 2} = 0: A{sub 1}(0) = 0.6200 {+-} 0.0056 {+-} 0.0065 {+-} 0.0071. Fixing the P-wave parameters we measure the phase of the S-wave for several values of the K{pi} mass. These results confirm those obtained with K{pi} production at small momentum transfer in fixed target experiments.

    We have studied dilepton production in a chemically equilibrating quark-gluon matter produced at RHIC energies.We find that the dilepton yield is no longer a monotonically decreasing function of the initial quark chemicalpotential. Therefore, the dilepton suppression may not be useful as a signature for quark-gluon matter formation.

    The branching fraction of the rate decay $B^0 \\rightarrow K^{*0}e^+e^-$ in the dilepton mass region from 30 to 1000 MeV$/c^2$ has been measured by the LHCb experiment, using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, at a centre-of-mass energy of 7 TeV. The decay mode $B^0 \\rightarrow J/\\psi(e^+e^-) K^{*0}$ is utilized as a normalization channel. The branching fraction $B^0 \\rightarrow K^{*0}e^+e^-$ is measured to be $$ B(B^0 \\rightarrow K^{*0}e^+e^-)^{30-1000 MeV/c^2}= (3.1\\, ^{+0.9\\mbox{} +0.2}_{-0.8\\mbox{}-0.3} \\pm 0.2)\\times 10^{-7}, $$ where the first error is statistical, the second is systematic, and the third comes from the uncertainties on the $B^0 \\rightarrow J/\\psi K^{*0}$ and $J/\\psi \\rightarrow e^+e^- $ branching fractions.

    2013-11-01

    Full Text Available After the discovery of a Higgs-like Boson with a mass close to 125 GeV at the LHC in summer 2012, we are showing the update on the analysis of the VH cannel. In this channel the Higgs-like Boson is produced in association with a vector boson and decaying into b quarks. We present the updated results on the full 2011 and 2012 7+8 TeV dataset. This poster will focus on one of the tree modes that are combined in this analysis, where the associated vector boson is a Z boson that is decaying leptonically into two electrons or muons, respectively.

    2013-01-01

    This document reports on a search for the Standard Model Higgs boson in the diphoton decay channel in proton-proton collisions at center-of-mass energies of $sqrt{s}=$7 TeV and $sqrt{s}=$ 8 TeV using integrated luminosities of 4.8 fb$^{-1}$ and 5.9 fb$^{-1}$, respectively, recorded with the ATLAS detector at the Large Hadron Collider. The search is performed for Higgs boson masses between 110 and 150 GeV. The expected exclusion limit at 95$%$ confidence level varies between 0.8 and 1.6 times the Standard Model cross section over the studied mass range, and results in an expected exclusion range from 110 GeV to 139.5 GeV. The observed exclusion ranges for a Standard Model Higgs boson are found to be (112-122.5) GeV and (132-143) GeV at 126.5 GeV with a local significance of 4.5 $sigma$. An excess is observed at 126.5 GeV with a signal strength of 1.8 over the SM expectation.

    This talk reports on a search for the Standard Model Higgs boson in the diphoton decay channel in proton-proton collisions at center-of-mass energies of sqrt(s) = 7 TeV and sqrt(s) = 8 TeV using integrated luminosities of 4.8 fb-1 and 5.9 fb-1, respectively, recorded with the ATLAS detector at the Large Hadron Collider. The search is performed for Higgs boson masses between 110 and 150 GeV. The expected exclusion limit at 95% confidence level varies between 0.8 and 1.6 times the Standard Model cross section over the studied mass range, and results in an expected exclusion range from 110 GeV to 139.5 GeV. The observed exclusion ranges for a Standard Model Higgs boson are found to be (112-122.5) GeV and (132−143)GeVat95126.5\\GeVwithalocalsignificanceof4.5\\sigma$. An excess is observed at 126.5 GeV with a signal strength of 1.8 over the SM expectation.

    The D0 Collaboration has performed a measurement of the top quark mass mt based on six candidate events for the process tt¯-->bW+b¯W-, where the W bosons decay to eν or μν. This sample was collected during an exposure of the D0 detector to an integrated luminosity of 125 pb-1 of s = 1.8 TeV pp¯ collisions. We obtain mt = 168.4+/-12.3\\(stat\\)+/-3.6\\(syst\\) GeV/c2, consistent with the measurement obtained using single-lepton events. Combination of the single-lepton and dilepton results yields mt = 172.0+/-7.5 GeV/c2.

    The mass of the Higgs boson is measured in the $H\\to ZZ^*\\to4\\ell$ and in the $H\\to\\gamma\\gamma$ decay channels with $36.1\\text{ fb}^{−1}$ of proton-proton collision data from the Large Hadron Collider at a centre-of-mass energy of $13\\text{ TeV}$ recorded by the ATLAS detector in 2015 and 2016. The measured value in the $H\\to ZZ^*\\to4\\ell$ channel is $m_H =124.88\\pm0.37\\text{ GeV}$, while the measured value in the $H\\to\\gamma\\gamma$ channel is $m_H=125.11\\pm0.42\\text{ GeV}$. The value of the Higgs boson mass obtained from a simultaneous fit to the invariant mass distributions in the two channels is $m_H=124.98\\pm0.28\\text{ GeV}$.

  12. Dilepton Production in Heavy-Ion Collisions

    2013-01-01

    The properties of electromagnetic radiation from hot fireballs as created in ultra-relativistic heavy-ion collisions are reviewed. We first outline how the medium effects in the electromagnetic spectral function, which governs thermal production rates, relate to the (partial) restoration of chiral symmetry. In particular, we show how chiral and QCD sum rules, together with constraints from lattice QCD, can render these relations quantitative. Turning to dilepton data, we elaborate on updates in the space-time evolution and quark-gluon plasma emission rates from lattice-QCD calculations. With a now available excitation function in dilepton spectra from the RHIC beam-energy scan connecting down to SPS energies, we argue that a consistent interpretation of dilepton data emerges. Combining well-constrained space-time evolutions with state-of-the-art emission rates identifies most of the radiation to emanate from around the pseudo-critical temperature, and thus confirms resonance melting as the prevalent mechanism...

    We present a measurement of the fraction f_+ of right-handed W bosons produced in top quark decays, based on a candidate sample of ttbar events in the l+jets and dilepton decay channels corresponding to an integrated luminosity of 370 pb^-1 collected by the DO detector at the Fermilab Tevatron ppbar Collider at sqrt{s}=1.96 TeV. We reconstruct the decay angle theta^* for each lepton. By comparing the \\cos\\theta^* distribution from the data with those for the expected background and signal for various values of f_+, we find $f_+=0.056 +- 0.080 (stat) +- 0.057 (syst)}. (f_+ < 0.23 at 95% C.L.), consistent with the standard model prediction of f_+=3.6 x10^-4.

  14. Chiral symmetry breaking, duality in the $\\overline{Q}q$ channel and $b \\to \\overline{c}cs$ decays

    We address the issue of the quark-hadron duality in the spectral densities induced by the heavy-light quark currents anti-Q q. In the limit m_Q ->oo, m_q ->0 we observe an enhancement of the physical spectral density compared to the quark one in the scalar and axial channels, due to the Goldstone meson contributions. This may imply that the scale where duality sets in in these channels is higher than in the vector (pseudoscalar) case. Implications for the nonleptonic decays of B mesons (the b -> anti-c cs transition) are considered.

    CERN Document Server

    Palmer, Jody David

    In this thesis partial production cross sections of t t events are measured in four channels, dened by the nal state leptons from the decay of the W bosons and the triggering lepton, using 5 : 6 fb -1of data taken with the ATLAS detector at p s = 7 TeV. The di-lepton channel is dened as having one electron and one muon in the nal state. The lepton plus tau channels are dened as having a nal state electron or muon and one hadronically decaying tau. Partial cross sections for these channels are estimated, and ratios of partial cross sections, dened with the same triggering lepton, are calculated. The di-lepton events are divided into two non-exclusive channels dened by the presence of a trigger matched lepton. The production cross-sections of t t events with nal states including an electron and a hadronically decaying tau, or an electron and a muon, were measured and used to calculate their ratio R e = 0 : 65 +0 : 12 -0.10 (stat.) + - 0.18(syst.).

    The inclusive reactions $pp \\rightarrow e^+ e^- X$ and $np \\rightarrow e^+ e^- X$ at the laboratory kinetic energy of 1.25 GeV are investigated in a model of dominance of nucleon and $\\Delta$ resonances. Experimental data for these reactions have recently been reported by the HADES Collaboration. In the original model, the dileptons are produced either from the decays of nucleon and $\\Delta$ resonances $R \\rightarrow N e^+ e^-$ or from the Dalitz decays of $\\pi^0$- and $\\eta$-mesons created i...

    The interference of the $\\rho^0$ and $\\omega$ mesons has been studied in the hadronic and leptonic decay channels, i.e., dipion and dilepton decay channels respectively, but this interference is not studied yet in the semihadronic or semileptonic decay channel, e.g., $V \\to \\pi^0\\gamma$. $V$ denotes either $\\rho^0$ or $\\omega$ meson. To look for the quoted interference in the $\\pi^0\\gamma$ decay channel as well as the contribution of $\\rho$ meson to the cross section, the correlated $\\pi^0\\gamma$ invariant mass distribution spectra are calculated in the photonuclear reaction in the multi-GeV region. It is assumed that these bosons arise in the final state due to the decay of $\\rho^0$ and $\\omega$ mesons which are photoproduced coherently in the isoscalar nucleus. The elementary reaction in the nucleus is considered to proceed as $\\gamma N \\to VN$; $V \\to \\pi^0\\gamma$. The forward propagation of the $\\rho$ and $\\omega$ mesons and the near forward emission of pion are considered, so that they can be described b...

    A search is presented for a standard model-like Higgs boson decaying to the $\\mu^+\\mu^-$ or $\\mathrm{e^+e^-}$ final states based on proton-proton collisions recorded by the CMS experiment at the CERN LHC. The data correspond to integrated luminosities of 5.0$~\\mathrm{fb}^{-1}$ at a centre-of-mass energy of $7~\\mathrm{TeV}$ and $19.7~\\mathrm{fb}^{-1}$ at $8~\\mathrm{TeV}$ for the $\\mu^+\\mu^-$ search, and of $19.7~\\mathrm{fb}^{-1}$ at a centre-of-mass energy of $8~\\mathrm{TeV}$ for the $\\mathrm{e^+e^-}$ search. To enhance the sensitivity of the search, events are categorized by topologies according to production process and dilepton invariant mass resolution. Upper limits on the production cross section times branching fraction at the 95% confidence level are reported for Higgs boson masses in the range from 120 to 150$~\\mathrm{GeV}$. For a Higgs boson with a mass of 125$~\\mathrm{GeV}$ decaying to $\\mu^+\\mu^-$, the observed (expected) upper limit on the production rate is found to be 7.4 ($6.5^{+2.8}_{-1.9}$) ti...
