Abstract: We have searched for the pair produced charged Higgs particles in the decays of Z0 for the decay channels of H + H − →τ + ντ − ν , H + H − →τν cs and H + H − → c s c s . The data sample analyzed corresponds to approximately 50 000 hadronic decays of Z0. A lower limit of 36.5 GeV is obtained at the 95% confidence level for the mass of charged Higgs particle, independent of its decay branching ratio.

Abstract: We have made a precise measurement of the cross section for e+e−→Z0→hadrons with the L3 detector at LEP, covering the s range from 88.28 to 95.04 GeV. From a fit to the Z0 mass, total width, and the hadronic cross section to be MZ0=91.160 ± 0.024 (experiment) ±0.030(LEP) GeV, ΓZ0=2.539±0.054 GeV, and σh(MZ0)=29.5±0.7 nb. We also used the fit to the Z0 peak cross section and the width todetermine Γinvisible=0.548±0.029 GeV, which corresponds to 3.29±0.17 species of light neutrinos. The possibility of four or more neutrino flavors is thus ruled out at the 4σ confidence level.

Abstract: The S matrix ansatz is a rigorously model independent approach to describe the cross-sections and asymmetries in e+e- annihilation. Using the cross-sections and asymmetries measured with the L3 detector during the 1990 and 1991 running period, we determine the mass and the width of the Z boson, the contributions of the Z exchange and of the yZ interference. Including the polarization of the t lepton in the analysis, the leptonic helicity amplitudes of the scattering process are determined assuming lepton universality. The results are compared with other model independent ansatzes as realized in ZFITTER. A systematic bias of the Z mass due to the yZ interference term is detected, which leads to an underestimation of the error on mz for model independent determinations., Facultad de Ciencias Exactas

Abstract: The effective electroweak mixing angle sin2θw is measured from the production and decay of the Z boson in e+e- interactions. The data sample corresponds to an integrated luminosity of 18 pb-l with about 420 000 hadronic and 40 000 leptonic Z decays. The mixing angle sin 22θw is determined from several independent measurements: the leptonic and hadronic cross sections, the forward-backward asymmetries of charged leptons and b-quarks, and the z-polarization. The results are found to be in good agreement with each other. The value of sin 22θw from a fit to the asymmetries in a model independent method is 0.2321-4-0.0021 and from a global fit to the data in the Standard Model framework is 0.2328±0.0013., Facultad de Ciencias Exactas

Abstract: We search for neutral heavy leptons that are isosinglets under the standard SU(2)L gauge group. Such neutral heavy leptons are expected in many extensions of the standard model. Three types of heavy leptons Ne, N(mu), N(tau) associated with the three neutrino types nu(e), nu(mu), nu(tau) have been directly searched for and no evidence for a signal has been found. We set the limit Br(Z0 --> nu(l)N(l)) < 3 x 10(-5) at the 95% CL for the mass range from 3 GeV up to m(Z).

Abstract: We report on a general search for neutral and charged Higgs bosons with no assumption that the Higgs sector consists of a single doublet as in the minimal standard model. No signal inconsistent with background is observed in any of the decay channels analysed. From the results of direct searches, model independent limits on Higgs bremsstrahlung and on Higgs pair production from the Z0 are presented. We interpret the bremsstrahlung limits in the general two-doublet model. Z0 lineshape measurements further restrict the parameter space available in the two-doublet model. Finally, the results are interpreted in the framework of the minimal supersymmetric extension of the standard model., Facultad de Ciencias Exactas

Abstract: We report on the measurement of the leptonic and hadronic cross sections and leptonic forward-backward asymmetries at theZ peak with the L3 detector at LEP. The total luminosity of 40.8 pb−1 collected in the years 1990, 1991 and 1992 corresponds to 1.09·106 hadronic and 0.98·105 leptonic Z decays observed. These data allow us to determine the electroweak parameters. From the cross sections we derive the properties of the Z boson: MZ=91195 ± 9 MeVΓZ=2494 ± 10 MeV Γhad=1748 ± 10 MeVΓℓ=83.49 ± 0.46MeV assuming lepton universality. We obtain an invisible width of Γinv=496.5 ± 7.9 MeV which, in the Standard Model, corresponds to a number of light neutrino species of Nv=2.981 ± 0.050. Using also the three leptonic forward-backward asymmetries and the average tau polarization, we determine the effective vector and axial-vector coupling constants of the neutral weak current to charged leptons to be: g¯ℓv=−0.0378+0.0045−0.0042 g¯ℓA=−0.4998 ± 0.0014. Within the framework of the Standard Model, and including our measurements of the Z→b¯b forward-backward asymmetry and partial decay width, we derive an effective electroweak mixing angle of sin2¯θW=0.2326 ± 0.0012 . We obtain an estimate for the strong coupling constant, αS=0.142 ± 0.013 and for the top-quark mass,mt =158+32−40 ± 19(Higgs) GeV, where the second error arises due to the uncertainty in the Higgs-boson mass., Facultad de Ciencias Exactas

Abstract: We present a study of the inclusive production of 7r °, r I, K ° and A based on 929,000 hadronic Z decays recorded with the L3 detector at LEP. The measured inclusive momentum distributions have been compared with predictions from parton shower models as well as an analytical Quantum Chromodynamics calculation. Comparing to low energy e+e - data, we find that QCD describes the energy evolution of the hadron spectrum., Facultad de Ciencias Exactas

Abstract: We report on a comparison of isolated hard photon production in hadronic Z decays with the predictions of a next-to-leading order matrix-element calculation. We constrain the quark electroweak couplings to the Z boson with a simultaneous fit to three direct photon distributions, and combine this result with an independent constraint from our measurement of the total hadronic width of the Z, obtaining cu = 0.92 ± 0.22 and cd = 1.63 ± 0.15 where c u,d = 4( g V 2 + g A 2 ) u,d . Our results are consistent with standard model predictions.

Abstract: We have searched for lepton flavour violation in Z boson decays into lepton pairs using all data collected with the L3 detector during the 1990, 1991 and 1992 runs on an event sample corresponding to 1 500 000 2?s produced. At the 95% confidence level the upper limits on the branching ratio for Z--,etz is 0.6X 10 -s, for Z--.er this is 1.3X 10 -5 and for Z--*/zT this is 1.9X 10 -s., Facultad de Ciencias Exactas

Abstract: In this report we summarize the major results from the first three years of running of the L3 detector at the Large Electron Positron collider (LEP). The L3 detector was designed to measure electrons, photons and muons with high precision; it has achieved (DELTAE/E) almost-equal-to 1.4% for electrons and photons at E = 45 GeV and (DELTAp/p) almost-equal-to 2.5% for muons at p = 45 GeV. Most of the experimental results presented are based on approximately 500 000 Z events. The data provide four independent checks of the Standard Model weak neutral currents to an accuracy of almost-equal-to 1%. These are: the measurement of Z parameters; the measurement of the forward-backward charge asymmetry of lepton pairs; the measurement of asymmetry parameters from Z --> bbBAR decays; and the measurement of the tau lepton polarization asymmetry. The data also provide information on weak charged currents from measurements of b hadrons such as decay width, lifetime, and B0-B0BAR mixing, and from measurements Of tau leptons such as their lifetime and branching ratios. The large number of Z events and the resolution of the L3 detector allow precision tests of QED and QCD, including the production of pi0, eta and hard photons. Leptonic final states with hard isolated photons are analyzed and high mass photon pairs are observed. Higgs boson production has not been observed and limits are given in the context of the Standard Model and its supersymmetric extensions. We also present upper limits on rare Z decays such as Z --> gammagammagamma and on flavor violating decays such as Z --> etau, mutau. Finally, upper limits obtained in the search for various new particles and new interactions are reported.

Abstract: The hadronic lineshape of the Z has been analyzed for evidence of signals of new, narrow vector resonances in the Z-mass range. The production rate of such resonances would be enhanced due to mixing with the Z. No evidence for new states is found, and it is thus possible to exclude, at the 95% confidence level, a quarkonium state in the mass range from 87.7 to 94.7 GeV.

Abstract: We report on inclusive chi(c) production in Z decays reconstructed via the decay mode chi(c) --> J + gamma. This analysis is based on 1.1 million hadronic Z events. Interpreting the observed signal as chi(c1), we obtain a branching ratio Br(Z --> chi(c1) + X) = (7.5 +/- 2.9(stat.) +/- 0.6(sys.)) x 10(-3). Assuming all events are produced in b decays we obtain Br(b --> chi(c1) + X) = (2.4 +/- 0.9(stat.) +/- 0.2(sys.)) x 10(-2). We also present an improved measurement of the branching ratio Br(Z --> J + X) = (3.6 +/- 0.5(stat.) +/- 0.4(sys.)) x 10(-3), obtained from dileptonic J decays.

Abstract: Within a context of evolution and the rapid integration of digitization in university publishing, the fields of the humanities and social sciences, and in particular those of textbooks, do not appear to have found a satisfactory distribution model. In this article, we shall attempt to explain in what measure this sector is different from other areas of university publishing and what hypotheses can be put forward for its future development. Having suggested a carving up of the university publishing market, we would like to place it briefly in an international context. On the basis of this finding, we will present the hypothesis of aggregation: why this should be required, why it does not yet exist and which needs it will respond to. We shall conclude by summarizing these points which we believe are key to the development of a digital university offer in France for the humanities and social sciences.

Abstract: Inclusive J production in Z0 decays is observed via the leptonic decay mode J → l+l− (l = e,μ). We measure the branching ratio Br(Z0 → J + X) = (4.1 ± 0.7 (stat.) ± 0.3 (sys.)) × 10−3. We have calculated the fraction of the J mesons from b-hadron decay and find a branching ratio of Br(b → J + X)= (1.3±0.2(stat.)±0.2(sys.)) × 10−2. We determine the average fractional energy of bottom hadrons 〈XE > = 0.70±0.03 (stat.)+0.02−0.01 (sys.) using the momentum spectrum of the J mesons. From a study of the angle between the J and the most energetic jet, we set an upper limit on the branching ratio Br ( Z 0 → q q g ∗ ; g ∗ → J + X ) −4 at 90% confidence level.

Abstract: The average lifetime of B hadrons produced in hadronic Z0 decays has been measured with the DELPHI detector at LEP. The measurement is based on the analysis of the impact parameter distributions of high pt muons and hadrons. The resulting mean B lifetimes are τB=(1.30±0.10±0.08)ps and τB=(1.27±0.04±0.12)ps respectively, giving a combined value of τB=(1.28±0.10)ps. The hadronic sample was also used to measure the partial Z0 width {Mathematical expression} and gave a value of 0.222-0.031+0.033±0.017. © 1992 Springer-Verlag., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: A search for the standard model neutral Higgs boson is described. Data collected during 1990 and 1991, corresponding to 408 000 hadronic decays of the Z°, were used. At the 95% confidence level we exclude the existence of the minimal standard model Higgs boson in the mass range 0⩽MH0, Facultad de Ciencias Exactas

Abstract: We have measured the cross-section of the production of single photon events in e + e- collisions near the Z ° resonance. For an integrated luminosity of 9.6 pb -1, we have observed 202 single photon candidates with energy between 0.9 and 3.5 GeV in the polar angular region between 45 ° and 135 °. Assuming that the only stable weakly interacting particles are light neutrinos with standard model couplings, we determine the number of light neutrino species to be Nv = 3.14 + 0.24 (stat.)4-0.12 (syst.). This corresponds to an invisible Z ° width of Finv = 524 + 40 4- 20 MeV., Facultad de Ciencias Exactas

Abstract: We report on a search for the neutral and charged Higgs bosons predicted by models of spontaneous symmetry breaking with more than one Higgs doublet field. No signals are observed. We set model-independent limits on masses or branching ratios of singly and pair-produced neutral and charged Higgs bosons. In addition, we interpret our results in the framework of a general two-doublet Higgs model and the Minimal Supersymmetric extension of the Standard Model., Facultad de Ciencias Exactas

Abstract: We report on a study of energetic, isolated photons in a sample of approximately 320 000 Z0 hadronic decays. Energetic isolated photons probe the short-distance structure of QCD. We compare our data with the prediction of several QCD-based calculations. A search for new processes with one or two photons in the hadronic final state is also presented. No evidence for physics beyond the standard model is found.

Abstract: The search for an additional heavy gauge boson Z ~ is described. The models considered are based on either a superstring-motivated E6 or on a left-right symmetry and assume a minimal Higgs sector. Cross sections and asymmetries measured with the L3 detector in the vicinity of the Z resonance during the 1990 and 1991 running periods are used to determine limits on the Z-Z' gauge boson mixing angle and on the Z' mass. For Z' masses above the direct limits, we obtain the following allowed ranges of the mixing angle, 0M, at the 95% confidence level: - 0.004 ≲ 0M ≲ 0.015 for the X model, - 0.003 ≲ 0M ≲ 0.020 for the g model, - 0.029 ≲ 0M ≲ 0.010 for the t/ model, - 0.002 ≲ 0M ≲ 0.015 for the LR model., Facultad de Ciencias Exactas
