Abstract: A study of neutral-current four-fermion processes is performed using a data sample corresponding to 55.3 pb-1 of integrated luminosity collected by the L3 detector at LEP at an average centre-of-mass energy of 183 GeV. The neutral-current four-fermion cross sections for final states with a pair of charged leptons plus jets and with four charged leptons are measured to be consistent with the Standard Model predictions. Events with fermion pair masses close to the Z boson mass are selected in all observable final states and the ZZ production cross section is measured to be σZZ=0.30+0.22+0.07−0.16−0.03 pb, in agreement with the Standard Model expectation. No evidence for the existence of anomalous triple gauge boson ZZZ and ZZγ couplings is found and limits on these couplings are set., Facultad de Ciencias Exactas

Abstract: A search for pair-produced charged Higgs bosons is performed with the L3 detector at LEP using data collected at centre-of-mass energies from 130 to 183 GeV, corresponding to an integrated luminosity of 88.3 pb-1 . The Higgs decays into a charm and a strange quark or into a tau lepton and its associated neutrino are considered. The observed candidates are consistent with the expectations from Standard Model background processes. A lower limit of 57.5 GeV on the charged Higgs mass is derived at 95% CL, independent of the decay branching ratio Br(H±→τν)., Facultad de Ciencias Exactas

Abstract: The coupling of the Z boson to quarks is studied in a sample of about 3.5 million hadronic Z decays collected by the L3 experiment at LEP from 1991 to 1995. The forward–backward quark charge asymmetry is measured by means of a jet charge technique. From the measured asymmetries, the effective weak mixing angle is determined to be sin2θW=0.2327±0.0012(stat.)±0.0013(syst.)., Facultad de Ciencias Exactas

Abstract: A determination of the number of light neutrino families performed by measuring the cross section of single photon production in eqey collision near the Z resonance is reported. From an integrated luminosity of 100 pby1 , collected during the years 1991–94, we have observed 2091 single photon candidates with an energy above 1 GeV in the polar angular region 458-u -1358. From a maximum likelihood fit to the single photon cross section, the Z decay width into invisible particles g is measured to be G s498"12 stat Ž . Ž. "12 sys MeV. Using the Standard Model couplings of neutrinos to the Z, the inv number of light neutrino species is determined to be N s2.98"0.07 stat Ž . Ž. "0.07 sys., Facultad de Ciencias Exactas

Abstract: We report on a study of radiative Bhabha and quasi-real Compton scattering at centre-of-mass energies between 50 GeV and 170 GeV, and 20 GeV and 140 GeV, respectively, using the L3 detector at LEP. The analysis is based on data corresponding to an integrated luminosity of 232.2 pb-1 . A total of 2856 radiative Bhabha and 4641 Compton scattering events are collected. Total and differential cross sections for both reactions are presented and found to be in good agreement with QED expectations. Our measurement of Compton scattering at the highest energies obtained so far is used to derive exclusion limits on the coupling λ for the on-shell production of an excited electron e★ decaying into a γe pair in the mass range 20 GeV < me★ < 170 GeV., Facultad de Ciencias Exactas

Abstract: Using the data collected with the L3 detector at LEP between 1990 and 1995, corresponding to an integrated luminosity of 149 pb(-1), the tau longitudinal polarisation has been measured as a function of the production polar angle using the tau decays tau(-) --> h(-)nu(tau) (h = pi,rho,a(1)) and tau(-)-->l(-)(l)nu(tau) (l = e,mu). From this measurement the quantities A(c) and A(tau), which depend on the couplings of the electron and the tau to the Z, are determined to be A(c) = 0.1678 +/- 0.0127 +/- 0.0030 and A(tau) = 0.1476 +/- 0.0088 +/- 0.0062, consistent with the hypothesis of e-tau universality, Under this assumption a value of A(l) = 0.1540 +/- 0.0074 +/- 0.0044 is obtained, yielding the value of the effective weak mixing angle sin(2)(W) = 0.2306 +/- 0.0011.

Abstract: We report on measurements of the inclusive production of J, $\psi'$ and $\mathrm{\chi_c}$ mesons in hadronic Z decays, based on 3.2 million hadronic events collected using the L3 detector at LEP. The J and $\psi'$ mesons are reconstructed through their decays into lepton pairs, while the $\mathrm{\chi_c}$ mesons are reconstructed via the decay mode $ \mathrm{\chi_c} \rightarrow \mathrm{J} + \gamma $. The measured branching fractions are: \begin{eqnarray*} \mathrm{Br(Z \rightarrow J + X)} &=& (3.40 \pm 0.23\:(\mathrm {stat.}) \pm 0.27\:(\mathrm {sys.}))\,\times\,10^{-3} \\ \mathrm{Br(Z \rightarrow \psi' + X)} &=& (1.6 \pm 0.5\:(\mathrm {stat.}) \pm 0.3\:(\mathrm {sys.}))\,\times\,10^{-3} \\ \mathrm{Br(Z \rightarrow \chi_{c1} + X)} &=& (2.7 \pm 0.6\:(\mathrm {stat.})\pm 0.5\:(\mathrm {sys.}))\, \times\,10^{-3}. \\ \end{eqnarray*} In the absence of a clear $\mathrm{\chi_{c2}}$ signal, the upper limit at 90\% C.L. is set: \mathrm{ Br(Z \rightarrow \chi_{c2} + X) 3.2\,\times\,10^{-3}}. \end{document}

Abstract: We present a combined measurement of $\Rb = \Gamma(\mathrm{Z \rightarrow b\overline{b}}) / \Gamma(\mathrm{Z} \rightarrow\mbox{hadro ns})$ and the semileptonic branching ratio of b quarks in Z decays, $\Brbl$, using double-tag methods. Two analyses are performed on one million hadronic Z decays collected in 1994 and 1995. The first analysis exploits the capabilities of the silicon microvertex detector. The tagging of b-events is based on the large impact parameter of tracks from weak b-decays with respect to the $\mathrm{e^+e^-}$ collision point. In the second analysis, a high-$p_t$ lepton tag is used to enhance the b-component in the sample and its momentum spectrum is used to constrain the model dependent uncertainties in the semileptonic b-decay. The analyses are combined in order to provide precise determinations of $\Rb$ and $\Brbl$: Rb = 0.2174 \pm 0.0015\mbox{(stat.)} \pm 0.0028\mbox{(sys.)}; $\Brbl = (10.16 \pm 0.13\mbox{(stat.)} \pm 0.30\mbox{(sys.)})\%.

No evidence for such particles is found in a data sample of 176 pb$^{-1}$. Improved upper limits for these particles are set on the production cross sections. 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 neutralino of 32.5 GeV and on the mass of the lightest chargino of 67.7 GeV.

Abstract: Measurements of the two-photon interaction e+e- --> e+e- hadrons at sqrt(s) = 91 GeV and sqrt(s) = 183 GeV are presented. The double-tag events, collected with the L3 detector, correspond to integrated luminosities of 140 pb-1 at 91 GeV and 52 pb-1 at 183 GeV. The cross-section of gamma*gamma* collisions has been measured at Q^2 = 3.5 GeV^2 and Q^2 = 14 GeV^2. The data agree well with predictions based on perturbative QCD, while the Quark Parton Model alone is insufficient to describe the data.

Abstract: We report the result of a search for scalar leptons in $\rm e^+e^-$, 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 $\rm e^+e^-$ 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 $0.74^{+0.15}_{-0.14}\,{(\rm stat.)}\,{\pm 0.04}\,{(\rm syst.)}\, \mathrm{pb}$. Final states containing b quarks are enhanced by a dedicated selection and their production cross section is found to be $0.18^{+0.09}_{-0.07}\,{(\rm stat.)}\,\pm 0.02\,{\rm (syst.)}\, \mathrm{pb}$. 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 excited leptons, $\rm e^*,~\mu^*, ~\tau^*, ~\nu_e^*, ~\nu_{\mu}^*$ and $\nu_{\tau}^*$, was performed with the L3 detector at LEP using data collected at a centre--of--mass energy of 189 GeV, corresponding to an integrated luminosity of $\rm 176~pb^{-1}$. No evidence of their production is observed. From the searches for pair produced excited leptons, lower mass limits are set close to the kinematic limit. From the searches for singly produced excited leptons, upper limits on their couplings are derived in the mass range up to $189$ GeV. A search for excited leptons, e ∗ , μ ∗ , τ ∗ , ν e ∗ , ν μ ∗ and ν τ ∗ , was performed with the L3 detector at LEP using data collected at a centre-of-mass energy of 189 GeV, corresponding to an integrated luminosity of 176 pb −1 . No evidence of their production is observed. From the searches for pair produced excited leptons, lower mass limits are set close to the kinematic limit. From the searches for singly produced excited leptons, upper limits on their couplings are derived in the mass range up to 189 GeV.

Abstract: We present results obtained from a study of the structure of hadronic events recorded by the L3 detector at a centre-of-mass energy of 183 GeV. The data sample corresponds to an integrated luminosity of 55.3 pb−1. The distributions of event shape variables and the energy dependence of their mean values are measured. From a comparison with resummed (αs2) QCD calculations, we determine the strong coupling constant. The charged particle multiplicity distribution and momentum spectrum are studied and the energy dependence of the peak position of the ξ(=−lnxp) distribution is compared with lower energy measurements and QCD expectations., Facultad de Ciencias Exactas

Abstract: Measurements of the two-photon interaction e+e- --> e+e- hadrons at sqrt(s) = 91 GeV and sqrt(s) = 183 GeV are presented. The double-tag events, collected with the L3 detector, correspond to integrated luminosities of 140 pb-1 at 91 GeV and 52 pb-1 at 183 GeV. The cross-section of gamma*gamma* collisions has been measured at = 3.5 GeV^2 and = 14 GeV^2. The data agree well with predictions based on perturbative QCD, while the Quark Parton Model alone is insufficient to describe the data.

Abstract: We search for anomalous ZZ gamma and Z gamma gamma couplings with the L3 detector at LEP, The analysis is based on the study of the process e(+) e(+) --> Z gamma at center-of-mass energies in the range 161 GeV < root s < 183 GeV. No evidence for anomalous effects is found. Limits at the 95% confidence level are set on the values of the eight possible anomalous couplings. Depending on the type of coupling new physics scales below 213 GeV to 1083 GeV are excluded. (C) 1998 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 $-0.86 < \lambda_\gamma < 0.75$.

Abstract: Time-dependent ${\mathrm{B^{0}}\mbox{-}\bar{\mathrm{B}} ^{0}}$ mixing is studied using about two million hadronic Z decays registered by L3 in 1994 and 1995. For this study three techniques are used. Tagging of the b-quark charge at decay time is performed by identifying leptons from semileptonic B decays. The flavour of the b quark at production time is determined from the charge of the lepton in the opposite hemisphere or by using a jet-charge technique. The proper time of the B-particle decay is obtained by reconstructing the production and decay vertices or by a measurement of the lepton impact parameter. The combined result for the frequency of ${\mathrm{B_d^0}}$ meson oscillations is \begin{displaymath} {\Delta m_d} = 0.444 \pm 0.040 \ \mathrm{ps}^{-1}. \end{displaymath} \end{abstract} \end{document}

Abstract: Events characterised by large hadronic energy and transverse momentum are selected from the data collected by the L3 detector at LEP at centre-of-mass energies between 161 and 172 GeV, corresponding to an integrated luminosity of 21 pb(-1) The visible mass and the missing mass distributions of the selected events are consistent with those expected from Standard Model processes. This result is combined with that from data taken at the Z resonance to sci an upper limit on the production rate and decay into invisible final states of a non-minimal Higgs boson. as a function of the Higgs mass. Assuming the non-minimal Higgs production cross section to be the same as for the Standard Model Higgs boson and the decay branching fraction into invisible final states to be 100%, a Higgs mass lower limit of 69.6 GeV is derived at 95% confidence level.

Abstract: We report on the measurement of W-boson pair-production with the L3 detector at LEP. In a data sample corresponding to a total luminosity of 55.47~pb$^{-1}$ collected at an average centre-of-mass energy of $182.68~\GeV$, we select 824 four-fermion events with pairs of hadronic jets or pairs of leptons with high invariant masses. Branching fractions of W decays into different fermion-antifermion pairs are determined. Assuming charged-current lepton universality, the branching fraction for hadronic W decays is measured to be: $ B(\mathrm{W\rightarrow hadrons}) = 70.1 \pm 1.3~(stat.) \pm 0.4~(syst.)~\%$. Combining all final states the total cross section for W-pair production is measured to be: $\SWW = 16.53 \pm 0.67~(stat.) \pm 0.26~(syst.)$~pb.

Abstract: We report on the measurement of W-boson pair-production with the L3 detector at LEP. In a data sample corresponding to a total luminosity of 55.47~pb$^{-1}$ collected at an average centre-of-mass energy of $182.68~\GeV$, we select 824 four-fermion events with pairs of hadronic jets or pairs of leptons with high invariant masses. Branching fractions of W decays into different fermion-antifermion pairs are determined. Assuming charged-current lepton universality, the branching fraction for hadronic W decays is measured to be: $ B(\mathrm{W\rightarrow hadrons}) = 70.1 \pm 1.3~(stat.) \pm 0.4~(syst.)~\%$. Combining all final states the total cross section for W-pair production is measured to be: $\SWW = 16.53 \pm 0.67~(stat.) \pm 0.26~(syst.)$~pb.

Abstract: The measurements of hadron and lepton-pair production cross sections and lepton-pair forward–backward asymmetries performed with the L3 detector at centre-of-mass energies between 130 GeV and 172 GeV are used to search for new physics phenomena. New physics effects involving four fermion vertices – contact interactions – are looked for in all channels. For hadron production the exchange of virtual leptoquarks and scalar quarks is studied. No evidence for deviations from the Standard Model expectations is found. Lower limits on the scale Λ of contact interactions in the range 1.2–7.1 TeV are obtained at the 95% confidence level for various models. Upper limits on the coupling strengths of leptoquarks and scalar quarks are derived., Facultad de Ciencias Exactas

Abstract: A measurement of the inclusive charmless semileptonic branching fraction of beauty hadrons, $\mathrm{b}\rightarrow\mathrm{X}_\mathrm{u }\ell\nu$, has been performed using almost two million hadronic Z decays collected by the L3 experiment at LEP, yielding the result: \begin{displaymath} \mathrm{Br}(\mathrm{b}\rightarrow\mathrm{X}_\mathr m{u}\ell\nu) = (3.3 \pm 1.0 \pm 1.7)\times 10^{-3}. \end{displaymath} The first uncertainty is statistical and the second is systematic. The modulus of the Cabibbo-Kobayashi-Maskawa matrix element $\mathrm{V_{ub}}$ extracted from this measurement is: \begin{displaymath} |\mathrm{V_{ub}}| = (6.0\, ^{+0.8}_{-1.0} \, ^{+1.4}_{-1.9} \pm 0.2)\times 10^{-3}, \end{displaymath} where the uncertainties are statistical, systematic and theoretical, respectively.

Abstract: We report on the first test of CP invariance in Z decays with hard photon radiation. The data recorded with the L3 detector at centre-of-mass energies near the Z resonance are used to search for CP violation in the reaction $\mathrm{e^+e^-}\rightarrow\mu^+\mu^-\gam ma$. No evidence for CP violation is found and limits on the CP-violating form factors $f^\mu_{\mathrm{A}}$ and $f^\mu_{\mathrm{V}}$ are derived.

Abstract: An analysis of single and multi-photon events with missing energy is performed using data collected with the L3 detector at LEP at centre-of-mass energies around 183\gev, for a total of 55.3 pb$^{-1}$ of integrated luminosity. The results obtained are in good agreement with the Standard Model prediction and are used to derive the value for the $\epem\ra\nnbar\gamma(\gamma)$ cross section as well as upper limits on cross sections of new physics processes. Several interpretations in supersymmetric models providing new limits on the masses of the lightest neutralino and of the gravitino are presented.

Abstract: Scalar leptons, charginos and neutralinos, predicted by supersymmetric theories, have been searched for in data samples collected with the L3 detector at centre-of-mass energies of 161 GeV and 172 GeV with integrated luminosities of 10.7 pb$^{-1}$ and 10.0 pb$^{-1}$ respectively. No evidence for such particles is found. New limits on production cross sections are set, assuming R--parity conservation. New exclusion contours in the Minimal Supersymmetric Standard Model parameter space as well as new lower limits on masses are derived.

Abstract: A search for unstable neutral and charged heavy leptons as well as for stable charged heavy leptons has been made at center-of-mass energies $\sqrt{s}$ = 161 GeV and $\sqrt{s}$ = 172 GeV with the L3 detector at LEP. No evidence for their existence was found. We exclude unstable neutral leptons of Dirac (Majorana) type for masses below 78.0 (66.7), 78.0 (66.7) and 72.2 (58.2) GeV, if the heavy neutrino couples to the electron, muon or tau family, respectively. We exclude unstable charged heavy leptons for masses below 81.0 GeV for a wide mass range of the associated neutral heavy lepton. The production of stable charged heavy leptons with a mass less than 84.2 GeV is also excluded. If the unstable charged heavy lepton decays via mixing into a massless neutrino, we exclude masses below 78.7 GeV.

Abstract: A measurement of the $\mathrm{K^0_s}$ and $\Lambda$ inclusive production rates and momentum spectra in two- and three-jet events is presented. On the basis of about 3.1~million Z decays collected with the L3 detector at LEP, we observe that the production of these particles is well modeled by string fragmentation.

Abstract: Using a sample of $\mathrm{e^{+}e^{-}}$ annihilation events collected with the L3 detector at the Z resonance corresponding to an integrated luminosity of 137 pb$^{-1}$, we have searched for anomalous production of $\gamma \mathrm{X}$ final states where $\mathrm{X}$ represents stable, weakly interacting particles and the photon energy is greater than 15 GeV. The sample of events found is consistent with Standard Model expectations. Upper limits are set on $\Z \gamma$ couplings, the $\tau$ neutrino magnetic moment, and the branching ratio for $\mathrm{Z} \rightarrow \gamma \mathrm{X}$.

Abstract: A study of neutral-current four-fermion processes is performed, using data collected by the L3 detector at LEP during high-energy runs at centre-of-mass energies 130 - 136, 161 and 170 - 172 GeV, with integrated luminosities of 4.9, 10.7 and 10.1 pb$^{-1}$, respectively. The total cross sections for the final states $ \ell\ell \ell^\prime \ell^\prime $ and $\rm \ell\ell qq $ ($\ell$,~$\ell^\prime $ = e, $\mu$ or $\tau$) are measured and found to be in agreement with the Standard Model prediction.

Abstract: We report on the measurement of W-boson pair-production with the L3 detector at LEP at a centre-of-mass energy of 161.34~\GeV. In a data sample corresponding to a total luminosity of 11~pb$^{-1}$, we select four-fermion events with high invariant masses of pairs of hadronic jets or leptons. Combining all final states, the measured total cross section for W-pair production is: $\SWW = 2.89^{+0.81}_{-0.70}~(stat.)\pm0.14~(syst.)$~pb. Within the Standard Model, this corresponds to a mass of the W boson of: $\MW = 80.80^{+0.48}_{-0.42}~(exp.)\pm 0.03$~(LEP)~\GeV. Limits on anomalous triple-vector-boson couplings are derived. \end{abstract}
