Abstract: From the analysis of a data sample corresponding to an integrated luminosity of 4.63 pb-1 taken during the 1990 run of LEP at centre of mass energies between 88.2 GeV an 94.2 GeV, the tau decays {Mathematical expression} and their charge conjugates have been studied. The following branching ratios have been measured; {Mathematical expression}, {Mathematical expression}, Br(τ- → π- (K-)vτ)=11.9±0.7±0.7%, BR (τ- → ρ- vτ)= 22.4±0.8±1.3%, in good agreement with world averages. The measured electronic and muonic branching ratios lead to a measurement of the strong coupling constant, αs (mτ) = 0.26-0.12 +0.09. Extrapolating the αs value from mτ to mZ yields αs (mZ) = 0.109-0.028 +0.012. The average polarization Pτ of taus produced in Z → τs τs decays has also been measured using the above decay modes. The weighted mean of the polarizations obtained from the four decay modes is Pτ=-0.24±0.07. This value of Pτ gives, in the improved Born approximation, a ratio between the axial and vector coupling constants of the tau of υτ/aτ = 0.12 ± 0.04, and hence a value of the effective electroweak mixing parameter sin2 θW(mZ 2). © 1992 Springer-Verlag., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

2. Top Physics at ATLAS 003

Author: Stavropoulos, G D
Subjects: Nonlinear Sciences::Exactly Solvable and Integrable Systems, High Energy Physics::Phenomenology, Physics::Atomic and Molecular Clusters, High Energy Physics::Experiment, Detectors and Experimental Techniques, Computer Science::Computers and Society
Abstract: The large number of ttbar events that will be produced at LHC, will allow very precise measurements of the properties of the top quark, which may also reveal New Physics. The mass of the top quark will be measured with a precision of about one GeV. Rare decays of the top quark can be probed fo r branching ratios as small as 10^-4. Finally, the detailed study of three different mechanisms of electroweak single top production will allow precise measurements of the CKM matrix element V_tb.

Abstract: MOORE (Muon Object Oriented REconstruction) is a package for track reconstruction in the ATLAS Muon Spectrometer, developed in C++ in the ATHENA framework and according to the standards provided by Object Orientation. This paper describes the MOORE structure and the reconstruction steps, including all the developments that led recently to the use of MOORE in the reconstruction of Data Challenge events, both for physics studies and for a first estimation of its performance as Event Filter, needed for the High Level Trigger Technical Design Report. Efficiency and resolution as a function both of eta and Pt have been estimated with single muons ranging from 3 GeV up to 1TeV. Preliminary results from a first attempt at reconstructing Z->2 muons and H->4 muons are also shown.

Subjects: Detectors and Experimental Techniques
Abstract: Reconstruction algorithms functioning at the Event Filter stage must be able both to validate or reject hypothesys formed at a previous stage in the triggering process and to operate in a general purpose mode, i.e. reconstructing the whole event in full scan. This note describes the implementation of a general purpose Muon Reconstruction package (Moore) as Event Filter. The strategy and the philosophy of the implementation are discussed, as well as the results in terms of efficiencies, resolution and time performances.

7. QCD Processes at the LHC

Author: Stavropoulos, G D
Subjects: High Energy Physics::Lattice, High Energy Physics::Phenomenology, High Energy Physics::Experiment, Detectors and Experimental Techniques
Abstract: The study of QCD processes at the LHC will serve two main goals. First the predictions of QCD will be tested and precision measurements will be performed. Second QCD processes represent a major part of the background to other Standard Model processes and signals of new physics at the LHC and thus need to be understood precisely in the new kinematic region available here. Furthermore, the production cross-sections for almost all processes are controlled by QCD.

Abstract: During the LEP running periods in 1990 and 1991 DELPHI has accumulated approximately 450000 Z0 decays into hadrons and charged leptons. The increased event statistics coupled with improved analysis techniques and improved knowledge of the LEP beam energies permit significantly better measurements of the mass and width of the Z0 resonance. Model independent fits to the cross sections and leptonic forward-backward asymmetries yield the following Z0 parameters: the mass and total width M(Z) = 91.187 +/- 0.009 GeV, GAMMA(Z) = 2.486 +/- 0.012 GeV, the hadronic and leptonic partial widths GAMMA(had) = 1.725 +/- 0.012GeV, GAMMA(l) = 83.01 +/- 0.52 MeV, the invisible width GAMMA(inv) = 512 +/- 10 MeV, the ratio of hadronic to leptonic partial widths R(l) = 20.78 +/- 0.15, and the Born level hadronic peak cross section sigma0 = 40.90 +/- 0.28 nb. Using these results and the value of alpha(s) determined from DELPHI data, the number of light neutrino species is determined to be 3.08 +/- 0.05. The individual leptonic widths are found to be: GAMMA(e) = 82.93 +/- 0.70 MeV, GAMMA(mu) = 83.20 +/- 1.11 MeV and GAMMA(tau) = 82.89 +/- 1.31 MeV. Using the measured leptonic forward-backward asymmetries and assuming lepton universality, the squared vector and axial-vector couplings of the Z0 to charged leptons are found to be g(V)l2 = (1.47 +/- 0.51) x 10(-3) and g(A)l2 = 0.2483 +/- 0.0016. A full Standard Model fit to the data yields a value of the top mass m(t) = 115(-82)+52 (expt.)-24(+23) (Higgs) GeV, corresponding to a value of the weak mixing angle sin2 theta(eff)lept = 0.2339 +/- 0.0015(expt.)-0.0004(+0.0001) (Higgs). Values are obtained for the variables S and T, or epsilon1 and epsilon3 which parameterize electroweak loop effects.

Abstract: The total and the differential cross sections for the reaction e+e- → γγ(γ) have been measured with the DELPHI detector at LEP using an integrated luminosity of 36.9 pb-1. The results agree with the QED predictions and consequently there is no evidence for non-standard channels with the same experimental signature. The lower limits obtained on the QED cutoff parameters are Λ+ > 143 GeV and Λ- > 120 GeV, and the lower bound on the mass of an excited electron with an effective coupling constant λγ = 1 is 132 GeV/c2. Upper limits on the branching ratios for the decays Z0 → γγ, Z0 → π0γ, Z0 → ηγ and Z0 → γγγ have been determined to be 5.5 × 10-5, 5.5 × 10-5, 8.0 × 10-5, and 1.7 × 10-5 respectively. All the limits are at the 95% confidence level.

Abstract: Strange beauty meson Bs0 have been reconstructed through exclusive hadronic final states, using the data collected in 1992 by the DELPHI experiment at the LEP collider. The analysis relies on the combined use of accurate tracking and of the hadron identification capabilities of DELPHI. Three Bs0 decay candidates have been selected over a negligible background using theDs−π+, Ds−a1+ (1260) and View the MathML source decay modes, with identified kaons in the final state. The Bs0 meson mass is measured to be mBs = (5374± 16± 2) MeV/ c2.

Abstract: A search for the Standard Model Higgs boson was performed in the data sample of around 1 million hadronic Z0 decays recorded in 1991 and 1992 with the DELPHI detector at LEP. The Higgs boson was searched for through its production in association with either neutrinos, electrons or muons. Four low mass events remain after the selections in the charged leptonic channels, that are likely to be due to background, especially four fermion processes. These results restrict the mass of the Standard Model Higgs boson to be larger than 55.7 GeV/c2 at the 95% confidence level.

Abstract: A determination of the hadronic fragmentation functions of the Z0 boson is presented from a study of the inclusive hadron production with the DELPHI detector at LEP. These fragmentation functions were compared with the ones at lower energies, thus covering data in a large kinematic range: 196 less-than-or-equal-to Q2 less-than-or-equal-to 8312 GeV2 and x (= p(h)/E(beam)) > 0.08. A large scaling violation was observed, which was used to extract the strong coupling constant in second order QCD: alpha(s)(M(Z)) = 0.118 +/- 0.005. The corresponding QCD scale for five quark flavours is: LAMBDA(MS)(5)BAR = 230 +/- 60 MeV.

Abstract: The strong coupling constant for b quarks has been determined, and its flavour independence, as predicted by QCD, investigated. The analysis involved events with lepton candidates selected from approximately 356 000 hadronic decays of the Z0, collected by the DELPHI detector at LEP in 1990 and 199 1. A method based on a direct comparison of the three-jet fraction in a b enriched sample, selected by requiring leptons with large momenta and transverse momenta, to that of the entire hadronic sample, illustrated the significant effect of the b quark mass on the multi-jet cross section, and verified the flavour independence of the strong coupling constant to an accuracy of +/- 6%. A second procedure based on a fit to the momentum and transverse momentum spectra of the lepton candidates in both two-jet and three (or more)-jet event samples simultaneously determined the b content in each, and, using second order QCD calculations, gave an absolute measurement of alpha(s) for b quarks of 0. 1 18 +/- 0.004 (stat.) +/- 0.003 (syst.) +/- 0.008 (scale). A comparison with a, for all quark flavours, as measured from the three-jet fraction in all hadronic events, further allowed the coupling strength for b quarks to be expressed in terms relative to that for udsc quarks, thereby cancelling certain common systematic uncertainties, and yielded alpha(s)b/alpha(s)udsc = 1.00 +/- 0.04 (stat.) +/- 0.03 (syst.).

Abstract: Two-particle correlations in invariant mass are studied separately for like-sign and unlike-sign pions. Strong correlations are observed only at small masses. The correlations decrease very rapidly for like-sign pions and slowly for unlike-sign pions, manifesting different particle dynamics. The like-sign correlations exhibit a power-law behaviour as a function of mass, compatible with the previously observed intermittency effect. The predictions of the parton shower model (JETSET 7.3) deviate significantly from the data. However, good agreement is obtained with the mass correlations, both for the unlike-sign and for the like-sign pairs if the production of the η′ and ρ0 mesons is reduced and Bose-Einstein correlations are included in the model. The value of the Bose-Einstein correlation strength is consistent with unity for pions which are produced directly or in the decays of short-lived resonances. © 1994 Springer-Verlag.

Abstract: The production of multihadronic states in γγ collisions at LEP has been studied with the DELPHI detector. The analyzed data correspond to an integrated luminosity of about 32pb-1, collected in the LEP runs of 1990-1992. Minimum bias data and a sample of events with jets at high pT have been selected under the requirement that no scattered electron or positron is observed. The two data sets have been compared to Monte Carlo predictions. The non-perturbative contribution described by the vector meson dominance Model and direct {Mathematical expression} production from pointlike photons described by the quark parton model were found to be insufficient to reproduce the data. It has been necessary to include a third interaction component, which is due to perburbative hard scattering of the partonic constituents of the photon. Several parametrisations of the quark and gluon densities of the photon have been tested. The interplay with the cut in jet transverse momentum, which is necessary for the separation of the perturbative and non-perturbative regions, is discussed. The data favour parametrisations with rather soft partonic content of the photon. © 1994 Springer-Verlag.
