Abstract: The cross section of charm production in γγ collisions σ(e+e−→e+e−cc̄X) is measured at LEP with the L3 detector at centre-of-mass energies from 91 GeV to 183 GeV. Charmed hadrons are identified by electrons and muons from semileptonic decays. The direct process γγ→cc̄ is found to be insufficient to describe the data. The measured cross section values and event distributions require contributions from resolved processes, which are sensitive to the gluon density in the photon., Facultad de Ciencias Exactas

Abstract: A search for a Higgs boson decaying into invisible particles is performed using the data collected at LEP by the L3 experiment at centre-of-mass energies of 183 GeV and 189 GeV. The integrated luminosities are respectively 55.3 pb−1 and 176.4 pb−1. The observed candidates are consistent with the expectations from Standard Model processes. In the hypothesis that the production cross section of this Higgs boson equals the Standard Model one and the branching ratio into invisible particles is 100%, a lower mass limit of 89.2 GeV is set at 95% confidence level., Facultad de Ciencias Exactas

Abstract: The cross section of the process e(+)e(-) --> Zgammagamma --> q (q) over bar gammagamma is measured with 215 pb(-1) of data collected with the L3 detector during the final LEP run at centre-of-mass energies around 205 GeV and 207 GeV No deviation from the Standard Model expectation is observed. The full data sample of 713 pb(-1), collected above the Z resonance, is used to constrain the coefficients of anomalous quartic gauge boson couplings to: -0.02 GeV-2 < a(0)/Lambda(2) < 0.03 GeV-2, -0.07 GeV-2 < a(c)/Lambda(2) < 0.05 GeV-2, at 95% confidence level.

Abstract: A search for the lightest neutral CP-even and neutral CP-odd Higgs bosons of the minimal supersymmetric standard model is performed using 216.6 pb(-1) of data collected with the L3 detector at LEP at centre-of-mass energies between 203 and 209 GeV. No indication of a signal is found. Including our results from lower centre-of-mass energies, lower limits on the Higgs boson masses are set as a function of tan beta for several scenarios. For tan beta greater than 0.7 they are m(h) > 84.5 GeV and m(A) > 86.3 GeV at 95% confidence level. (C) 2002 Published by Elsevier Science B.V.

Abstract: The process e(+)e(-) --> Z gamma gamma - gamma> is studied in 0.5 fb(-1) of data collected with the L3 detector at centre-of-mass energies between 130.1 GeV and 201.7 GeV. Cross sections are measured and found to be consistent with the Standard Model expectations. The study of the least energetic photon constrains the quartic gauge boson couplings to -0.008 GeV(-2) < a(0)/Lambda (2) < 0.005 GeV(-2) and -0.007 GeV(-2) < a(c)/Lambda (2) < 0.011 GeV-2, at 95% confidence level.

Abstract: A search for the lightest neutral CP-even and the neutral CP-odd Higgs bosons of the Minimal Supersymmetric Standard Model is performed using 233.2 pb-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies 192-202 GeV. No signal is observed and lower mass limits are given as a function of tan(beta) for two scalar top mixing hypotheses. For tan(beta) greater than 0.8, they are mh > 83.4 GeV and mA > 83.8 GeV at 95 % confidence level.

Abstract: The cross section for the production of Z boson pairs is measured using the data collected by the L3 detector at LEP in 1999 in e(+)e(-) collisions at centre-of-mass energies ranging from 192 GeV up to 202 GeV. Events in all the visible final states are selected, measuring the cross section of this process. The special case of final states containing b quarks is also investigated. All results are in agreement with the Standard Model predictions. (C) 2001 Elsevier Science B.V. All rights reserved.

Abstract: The production of c and b quarks gamma gamma collisions is studied with the L3 detector at LEP with 410 pb(-1) of data, collected at centre-of-mass energies from 189 GeV to 202 GeV. Hadronic final states containing c and b quarks are identified by detecting electrons or muons from their semileptonic decays. The cross sections sigma (e(+)e(-) --> e(+)e(-)c (c) over barX) and sigma (e(+)e(-) --> e(+)e(-)b (b) over barX) are measured and compared to next-to-leading order perturbative QCD calculations. The cross section of b production is measured in gamma gamma collisions for the first time. It is in excess of the QCD prediction by a factor of three. (C) 2001 Published by Elsevier Science B.V.

Abstract: Open charm production in gamma-gamma collisions is studied with data collected at e+e- centre-of-mass energies from 189 GeV to 202 GeV corresponding to a total integrated luminosity of 410 pb-1. The charm cross section sigma(gamma gamma ---> c c~ X) is measured for the first time as a function of the two-photon centre-of-mass energy in the interval from 5 GeV to 70 GeV and is compared to NLO QCD calculations. Open charm production in γγ collisions is studied with data collected at e + e − centre-of-mass energies from 189 GeV to 202 GeV corresponding to a total integrated luminosity of 410 pb −1 . The charm cross section σ(γγ→ c c ̄ X ) is measured for the first time as a function of the two-photon centre-of-mass energy in the interval from 5 GeV to 70 GeV and is compared to NLO QCD calculations.

Abstract: The data collected by the L3 experiment at LEP at a centre-of-mass energy of 188.6 GeV are used to measure the W-pair production cross section and the W-boson decay branching fractions. These data correspond to an integrated luminosity of 176.8 pb-l. The total cross section for W-pair production, combining all final states, is measured to be sigma (W) = 16.24 +/- 0.37 (stat.) +/- 0.22 (syst.) pb. Including our data collected at lower centre-of-mass energies, the hadronic branching fraction of the W-boson is determined to be B(W --> qq) = [68.20 +/- 0.68 (stat.) +/- 0.33 (syst.)]%. The results agree with the Standard Model predictions. (C) 2000 Published by Elsevier Science B.V.

Abstract: A first measurement of the cross section of the process e(+)e(-) --> Z gamma gamma is reported using a total integrated luminosity of 231 pb(-1) collected with the L3 detector at centre-of-mass energies of 182.7 GeV and 188.7 GeV. By selecting hadronic events with two isolated photons the e(+)e(-) --> Z gamma gamma cross section is measured to be 0.49(-0.17)(+0.20) +/- 0.04 pb at 182.7 GeV and 0.47 +/- 0.10 +/- 0.04 pb at 188.7 GeV. The measurements are consistent with Standard Model expectations. Limits on Quartic Gauge Boson Couplings a(0)/Lambda(2) and a(c)/Lambda(2) of -0.009 GeV-2 < a(0)/Lambda(2) < 0.008 GeV-2 and -0.007 GeV-2 < a(c)/Lambda(2) < 0.013 GeV-2 are derived at 95% confidence level.

Abstract: We report the result of a search for scalar leptons in e(+)e(-) collisions at 189 GeV centre-of-mass energy at LEP. No evidence for such particles is found in a data sample of 176 pb(-1). Improved upper limits are set on the production cross sections for these new particles. New exclusion contours in the parameter space of the Minimal Supersymmetric Standard Model are derived, as well as new lower limits on the masses of these supersymmetric particles. Under the assumptions of common gaugino and scalar masses at the GUT scale, we set an absolute lower limit on the mass of the lightest scalar electron of 65.5 GeV.

Abstract: The pair production of Z bosons is studied using the data collected by the L3 detector at LEP in 1998 in e(+)e(-) collisions at a centre-of-mass energy of 189 GeV. All the visible final states are considered and the cross section of this process is measured to be 0.74(-0.14)(+0.15)(stat.) +/- 0.04(syst)pb. Final states containing b quarks are enhanced by a dedicated selection and their production cross section is found to be 0.18(-0.07)(+0.09)(stat) +/- 0.02(syst) pb. Both results are in agreement with the Standard Model predictions. Limits on anomalous couplings between neutral gauge bosons are derived from these measurements.

Abstract: A search for pair-produced charged Higgs bosons is performed with the L3 detector at LEP using data collected at a centre-of-mass energy of 188.6 GeV, corresponding to an integrated luminosity of 176.4 pb(-1). Higgs decays into a charm and a strange quark or into a tau lepton and its associated neutrino are considered. The observed events are consistent with the expectations from Standard Model background processes. A lower limit of 65.5 GeV on the charged Higgs mass is derived at 95% confidence level, independent of the decay branching ratio Br(H+/- --> tau nu). (C) 1999 Published by Elsevier Science B.V.

Abstract: A search for the Standard Model Higgs boson is carried out on 176.4 pb(-1) of data collected by the L3 detector at a center-of-mass energy of 189 GeV. The data are consistent with the expectations of Standard Model processes and no evidence of a Higgs signal is observed. Combining the results of this search with those at lower center-of-mass energies, a lower limit on the mass of the Standard Model Higgs boson of 95.3 GeV is set at the 95% confidence level.

Abstract: A search for the lightest neutral scalar and neutral pseudoscalar Higgs bosons in the Minimal Supersymmetric Standard Model is performed using 176.4 pb(-1) of integrated luminosity collected by L3 at a center-of-mass energy of 189 GeV. No signal is observed, and the data are consistent with the expected Standard Model background. Lower limits on the masses of the lightest neutral scalar and pseudoscalar Higgs bosons are given as a function of tan beta. Lower mass limits for tan beta > 1 are set at the 95% confidence level to be m(h) > 77.1 GeV and m(A) > 77.1 GeV. (C) 1999 Elsevier Science B.V. All rights reserved.

Abstract: We report on a study of single W boson production in a data sample collected by the L3 detector at centre-of-mass energies from 130 to 183 GeV. The signal consists of large missing energy final states with a single energetic lepton or two hadronic jets. The measured cross sections at five different centre-of-mass energies are consistent with the Standard Model expectations. The following limits on the anomalous WW gamma gauge couplings are derived at 95% CL: - 0.46 < Delta kappa(gamma) < 0.57 and - 0.86 < lambda(gamma) < 0.75. (C) 1998 Elsevier Science B.V.

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.
