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: Looking for phenomena beyond the Standard Model (SM) in rare decays is a complementary approach to direct searches for New Physics (NP) at colliders. One of the theoretically cleanest processes is the ultra rare decay K+ → π+νν. The goal of the NA62 experiment at CERN SPS is to measure the branching ratio (BR) of this decay with 10% precision. The experiment has been launched in 2014. In 2015, the detector was commissioned at a low intensity beam. The experimental setup is described and performances achieved in 2015 are discussed in view of the final measurement.

Abstract: The NA62 experiment at the CERN SPS is designed to measure the branching ratio of the ultra-rare decay K+->pi+ nu nubar with 10% precision. For this purpose the experiment aims to collect of the order of 100 K+->pi+ nu nubar events which would require at least 10^13 K+ decays in the fiducial volume of the detector. The large sample of K+ decays that will be available at NA62 allows the experiment to carry out a rich program for rare and forbidden K+ and pi0 decays, including lepton flavour and/or number violating modes, sterile neutrinos, exotic particles (e.g. Dark Photons). NA62's potential for such searches in K+ and pi0 decays is discussed, with initial sensitivity estimates. In addition, plans for continuing the experiment after 2021 (Long Shutdown 2) are presented, including in particular the possibility to operate in a beam-dump mode for exploring various Dark Matter scenarios.

Abstract: The flavor physics sector allows us to explore the possible extensions of the Standard Model (SM) in a complementary approach to the direct searches conducted i.e. at the Large Hadron Collider (LHC). New physics contributions at high energy scales can manifest themselves in low energy phenomena provided that the observables are carefully chosen, precisely measured and compared to accurate predictions. A stringent test of the SM predictions is the observation of the rare decay K+ to pi+ nu nubar. The NA62 experiment at CERN is designed to measure the branching ratio (BR) of this decay with 10% precision. NA62 has been successfully launched in October 2014, took data in pilot runs in 2014 and 2015 achieving the commissioning of the detectors and the designed beam intensity. The NA62 experimental setup is described and the quality of data collected in view of the final measurement is reported.

Abstract: NA62 is a fixed target experiment located at the CERN SPS which aims to perform flavour physics studies in the charged kaon sector with an unprecedented precision. Due to the abundance of kaon decays with a po in the final state, NA62 is also a perfect environment to measure the neutral pion characteristics. NA62 collected a large sample of charged kaon decays with a highly efficient trigger for decays into electrons in 2007. We report about the measurement of the po electromagnetic transition form factor slope parameter in the time-like region. Between 2008 and 2014 the NA62 apparatus underwent an intense upgrade phase to improve the physics sensitivity of the experiment to precisely measure the Br (K+ !p+n ¯ n). NA62 took data in pilot runs in 2014 and 2015 reaching the final designed beam intensity. The quality of data acquired in view of the final measurement is presented.

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: Two-photon formation of the charmonium resonance $\chi_{{\rm c}2}$ has been studied with the L3 detector at LEP. The $\chi_{{\rm c}2}$ is identified through its decay $\chi_{{\rm c}2} \rightarrow \gamma {\rm J}$, with a subsequent decay ${\rm J} \rightarrow {\mathrm{e^+ e^-}}$ or ${\rm J} \rightarrow {\mathrm{\mu^+ \mu^-}}$. With an integrated luminosity of 140 pb$^{-1}$ at $\sqrt{s} \simeq$ 91~\textrm{Ge\kern -0.1em V} and 52 pb$^{-1}$ at $\sqrt{s} \simeq$ {Ge\kern -0.1em V}, we measure the two-photon width of the $\chi_{{\rm c}2}$ to be \begin{center} $\Gamma_{\gamma\gamma}(\chi_{{\rm c}2})=1.02 \pm 0.40 \mbox{$\;$(stat.)} \pm 0.15 \mbox{$\;$(sys.)} \pm 0.09(\rm{BR.}) {\mathrm{\ ke\kern -0.1em V}}$.

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: 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: In 2007 the NA62 experiment at CERN collected a large sample of charged kaon decays with a highly efficient trigger selecting events with electrons in the final state. The kaon beam represents a rich source of tagged neutral pion decays in vacuum. The electromagnetic transition form factor slope of the π(0) in the time-like region has been measured from about 10(6) fully reconstructed π(0) Dalitz decays collected in 2007. The preliminary result a = (3.68 ± 0.51(stat) ± 0.25(syst)) × 10(-2) is the most precise to date. This value is compatible with theoretical expectations and consistent with the previous measurements.

Abstract: Using data collected with the L3 detector near the Z resonance, corresponding to an integrated luminosity of 150 pb−1, the branching fractions of the tau lepton into electron and muon are measured to be B(τ → eν ̄eντ ) = (17.806 ± 0.104 (stat.) ± 0.076 (syst.))%, B(τ → μν ̄μντ ) = (17.342±0.110 (stat.)±0.067 (syst.))%. From these results the ratio of the charged current coupling constants of the muon and the electron is determined to be gμ/ge = 1.0007 ± 0.0051. Assuming electron-muon universality, the Fermi constant is measured in tau lepton decays as GF = (1.1616± 0.0058) × 10−5 GeV−2. Furthermore, the coupling constant of the strong interaction at the tau mass scale is obtained as αs(m2 τ ) = 0.322 ± 0.009 (exp.) ± 0.015 (theory)., Facultad de Ciencias Exactas

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: A search for pair-produced charged Higgs bosons is performed with the L3 detector at LEP using data collected at centre-of- mass energies between 192 and 202 GeV, corresponding to an integrated luminosity of 233.2 pb−1. Decays into a charm and a strange quark or into a tau lepton and its neutrino are considered. The observed events are consistent with the expectations from Standard Model background processes. Including data taken at lower centre-of-mass energies, lower limits on the charged Higgs mass are derived at the 95% confidence level. They vary from 67.4 to 79.9 GeV as a function of the H± → τν branching ratio., Facultad de Ciencias Exactas

Abstract: A search for charginos nearly mass-degenerate with the lightest supersymmetric particle is performed using the 176 pby1 of data collected at 189 GeV in 1998 with the L3 detector. Mass differences between the chargino and the lightest supersymmetric particle below 4 GeV are considered. The presence of a high transverse momentum photon is required to single out the signal from the photon-photon interaction background. No evidence for charginos is found and upper limits on the cross section for chargino pair production are set. For the first time at LEP2, in the case of heavy scalar leptons, chargino mass limits are obtained for any χ̃±1−χ̃01 mass difference., Facultad de Ciencias Exactas

Abstract: The three different helicity states of W± bosons, produced in the reaction e+e−→W+W−→ℓνqq̄ are studied using leptonic and hadronic W decays at √s = 183 GeV and 189 GeV. The W polarisation is also measured as a function of the scattering angle between the W- and the direction of the e- beam. The analysis demonstrates that W bosons are produced with all three helicities, the longitudinal and the two transverse states. Combining the results from the two center-of-mass energies and with leptonic and hadronic W decays, the fraction of longitudinally polarised W± bosons is measured to be 0.261 ± 0.051 (stat.) ± 0.016 (syst.) in agreement with the expectation from the Standard Model., Facultad de Ciencias Exactas

Abstract: New measurements at a centre-of-mass energy √s ≃183 GeV of the hadronic photon structure function Fγ2(x) in the Q2 interval, 9 GeV2 ≤ Q2 ≤ 30 GeV2 , are presented. The data, collected in 1997 with the L3 detector, correspond to an integrated luminosity of 51.9 pb-1 . Combining with the data taken at a centre-of-mass energy of 91 GeV, the evolution of Fγ2 with Q2 is measured in the Q2 range from 1.2 GeV2 to 30 GeV2. Fγ2 shows a linear growth with lnQ2; the value of the slope α−1dFγ2(Q2)/dlnQ2 is measured in two x bins from 0.01 to 0.2 and is somewhat higher than predicted., Facultad de Ciencias Exactas

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: A search for the lightest neutral scalar and neutral pseudoscalar Higgs bosons in the Minimal Supersymmetric Standard Model is performed on data collected at LEP by the L3 detector at center-of-mass energies 130 GeVF's F183 GeV. No significant excess of events is observed. Limits on the masses of the lightest neutral and pseudoscalar Higgs bosons are given as a function of tanb. Lower mass limits at the 95% confidence level are set at m )70.7 GeV and m )71.0 GeV., Facultad de Ciencias Exactas

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: 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 search for the Standard Model Higgs boson is performed with the L3 detector at LEP. The data sample, corresponding to a luminosity of 55.3 pb(-1), was collected at an average centre-of-mass energy of 182.7 GeV, No Higgs signal is observed, leading to a lower limit on the Higgs boson mass of 87.6 GeV at the 95% confidence level.

Abstract: The hadronic photon structure function Fγ2 is studied in the reaction e+e− → e+e−hadrons at LEP with the L3 detector. The data, collected from 1991 to 1995 at a centre-of-mass energy √s = ≃ 91 GeV, correspond to an integrated luminosity of 140 pb−1. The photon structure function Fγ2 is measured in the Q2 interval 1.2 GeV2 ≤ Q2 ≤ 9.0 GeV2 and the x interval 0.002 < x < 0.2. Fγ2 shows a linear growth with lnQ2. The value of the slope α−1dFγ2(Q2)/dlnQ2 is measured to be 0.079±0.011±0.009., Facultad de Ciencias Exactas

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 search for chargino, neutralino and scalar lepton pair-production in $\mathrm{e^+e^-}$ collisions at the centre-of-mass energy of 189 GeV is performed under the assumptions that R-parity is not conserved in decays and only one of the coupling constants $\lambda_{ijk}$, $\lambda'_{ijk}$ or $\lambda''_{ijk}$ is non-negligible. No signal is found in a data sample corresponding to an integrated luminosity of 176.4 pb$^{-1}$. Limits on the production cross sections, on the Minimal Supersymmetric Standard Model parameters and on the masses of the supersymmetric particles are derived.

Abstract: We present a study of the inclusive $\omega$ and $\eta^{\prime}$ production based on 3.1 million hadronic Z decays recorded with the L3 detector at LEP during 1991--1994. The production rates per hadronic Z decay have been measured to be $1.17 \pm 0.17 $ $\omega$ mesons and $0.25 \pm 0.04 $ $\eta^{\prime}$ mesons. The production rates and the differential cross sections have been compared with predictions of the JETSET and the HERWIG Monte Carlo models. We have observed that the differential cross sections can be described by an analytical quantum chromodynamics calculation. \end{document}

Abstract: The formation of the η′ in the reaction e+e−→e+e−η′→e+e−π+π−γ has been measured by the L3 detector at a centre-of-mass energy of 91 GeV. The radiative width of the η′ has been found to be Γγγ=4.17±0.10(stat.)±0.27(sys.)keV. The Q2 dependence of the η′ formation cross section has been measured for Q2≤10GeV2 and the η′ electromagnetic transition form factor has been determined. The form factor can be parametrised by a pole form with Λ=0.900±0.046(stat.)±0.022(sys.)GeV. It is also consistent with recent non-perturbative QCD calculations., Facultad de Ciencias Exactas

Abstract: We report on a search for R-parity breaking effects due to supersymmetric tau-sneutrino exchange in the reactions e(+)e(-) --> e(+)e(-) and e(+)e(-) --> mu(+)mu(-) at centre-of-mass energies from 91 GeV to 172 GeV, using the L3 detector at LEP. No evidence for deviations from the Standard Model expectations of the measured cross sections and forward-backward asymmetries for these reactions is found. Upper Limits for the couplings lambda(131) and lambda(232), for sneutrino masses up to m(tau) less than or equal to 190GeV are determined from an analysis of the expected effects due to tau sneutrino exchange.

Abstract: A search for exclusive decays of $\ensuremath{\mathrm{B_d^0}}$ and $\ensuremath{\mathrm{B_s^0}}$ mesons has been performed in the channels $\ensuremath{\mathrm{B_d^0}\rightarrow\mathrm{J}\eta}$,\,\, $\ensuremath{\mathrm{B_s^0}\rightarrow\mathrm{J}\eta}$,\,\, $\ensuremath{\mathrm{B_d^0}\rightarrow\mathrm{J}\pi^0}$ and $\ensuremath{\mathrm{B_s^0}\rightarrow\mathrm{J}\pi^0}$. The data sample consisted of more than three and half million hadronic $\ensuremath{\mathrm {Z}}$ decays collected by the L3 experiment at LEP from 1991 through 1995. No candidate events have been observed for any of the modes thus determining upper limits at 90\% confidence level: $3.2\times 10^{-4}$ on $\mathrm{Br}(\ensuremath{\mathrm{B_d^0}\ rightarrow\mathrm{J}\pi^0)}$ and the first experimental limits: \begin{eqnarray*} \mathrm{Br}(\ensuremath{\mathrm{B_d^0}\rightarrow \mathrm{J}\eta}) & < & 1.2\times 10^{-3},\\ \mathrm{Br}(\ensuremath{\m athrm{B_s^0}\rightarrow\mathrm{J}\eta}) & < & 3.8\times 10^{-3},\\ \mathrm{Br}(\ensuremath{\mathrm{B_s^0}\rightarrow\mathrm {J}\pi^0}) & < & 1.2\times 10^{-3}.\\ \end{eqnarray*}

Abstract: The NA62 experiment at CERN SPS aims to measure the branching ratio of the ultra-rare kaon decay $K^+\to\pi^+\nu\bar{\nu}$ with 10\% precision, collecting $\sim 100$ events, assuming the Standard Model~(SM) branching ratio of $8.4 \times 10^{-11}$, starting in 2016. The NA62 experiment uses a kaon decay-in-flight technique and is exposed to a 750~MHz high-energy unseparated charged hadron beam, in which kaons are a minor component (6\%). Kaon identification is therefore mandatory to reduce the interference of the dominant non-kaon component with the experimental measurements. The NA62 kaon identification system and its performances are presented., Comment: 6 pages. To be published in ICHEP 2016 conference proceedings

Abstract: The reaction e+e-→e+e-y*y*→e+e- hadrons is analysed using data collected by the L3 detector during the LEP runs at √s= 130-140 GeV and √s= 161 GeV. The cross sections σ(e+e-→e+e-hadrons) and σ(yy → hadrons) are measured in the interval 5 ≤ Wyy ≤ 75 GeV. The energy dependence of the σ(yy → hadrons) cross section is consistent with the universal Regge behaviour of total hadronic cross sections., Facultad de Ciencias Exactas

Abstract: The tau lepton lifetime is measured with the L3 detector at LEP using the complete data taken at centre-of-mass energies around the Z pole resulting in tau_tau = 293.2 +/- 2.0 (stat) +/- 1.5 (syst) fs. The comparison of this result with the muon lifetime supports lepton universality of the weak charged current at the level of six per mille. Assuming lepton universality, the value of the strong coupling constant, alpha_s is found to be alpha_s(m_tau^2) = 0.319 +/- 0.015(exp.) +/- 0.014 (theory). The tau lepton lifetime is measured with the L3 detector at LEP using the complete data taken at centre-of-mass energies around the Z pole resulting in τ τ =293.2 ± 2.0 (stat) ± 1.5 (syst) fs . The comparison of this result with the muon lifetime supports lepton universality of the weak charged current at the level of six per mille. Assuming lepton universality, the value of the strong coupling constant, α s is found to be α s ( m τ 2 ) = 0.319 ± 0.015 (exp) ± 0.014 (theory).

Abstract: A search is performed for a Higgs boson produced in association with a Z boson and decaying into two photons, using the L3 data collected at LEP at a centre-of-mass energy of 189 GeV. All decay modes of the Z are considered. No signal is observed and limits on the branching fraction of the Higgs boson decay into two photons as a function of the Higgs mass are derived assuming a Standard Model production rate. A lower limit on the mass of a fermiophobic Higgs is set at 94.9 GeV at 95% confidence level., Facultad de Ciencias Exactas

Abstract: The Standard Model Higgs boson is searched for in 233.2 pb−1 of data collected by the L3 detector at centre of mass energies from 192 GeV to 202 GeV. These data are consistent with the expectations of Standard Model processes and no evidence of a Higgs signal is observed. A lower limit on the mass of the Standard Model Higgs boson of 107.0 GeV is set at the 95% confidence level., Facultad de Ciencias Exactas

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: We present results obtained from a study of the structure of hadronic events recorded by the L3 detector at various centre-of-mass energies. The distributions of event shape variables and the energy dependence of their mean values are measured from 30 GeV to 189 GeV and compared with various QCD models. The energy dependence of the moments of event shape variables is used to test a power law ansatz for the non-perturbative component. We obtain a universal value of Ž 2 the non-perturbative parameter a s 0.537 ± 0.073. From a comparison with resummed O(αs2)QCD calculations, we 0 s determine the strong coupling constant at each of the selected energies. The measurements demonstrate the running of αs as expected in QCD with a value of αs(mZ) = 0.1215 ± 0.0012 (exp) ± 0.0061 (th)., Facultad de Ciencias Exactas

Abstract: Extra spatial dimensions are proposed by recent theories that postulate the scale of gravity to be of the same order as the electroweak scale. A sizeable interaction between gravitons and Standard Model particles is then predicted. Effects of these new interactions in boson and fermion pair production are searched for in the data sample collected at centre-of-mass energies above the Z pole by the L3 detector at LEP. In addition, the direct production of a graviton associated with a Z boson is investigated. No statistically significant hints for the existence of these effects are found and lower limits in excess of 1 TeV are derived on the scale of this new theory of gravity, Facultad de Ciencias Exactas

Abstract: A search for rare charmless decays of B0d and B0s mesons has been performed in the exclusive channels B0d(s) →ηη0, B0d(s) →ηπ0 and B0d(s) →π0π0. The data sample consisted of three million hadronic Z decays collected by the L3 experiment at LEP from 1991 through 1994. No candidate event has been observed and the following upper limits at 90% confidence level on the branching ratios have been set: Br(B0d→ηη) −4, Br(B0s →ηη) < 1.5 x 10−3, Br(B0d→ηπ0) < 2.5 x 10−4, Br(B0s→ηπ0) < 1.0 x 10−3, Br(B0d→π0π0) < 6.0 x 10−5, Br(B0s→π0π0) < 2.1 x 10−4. These are the first experimental limits on Bd0→ηη and on the Bs0 neutral charmless modes., Facultad de Ciencias Exactas

Abstract: An upper limit on the lifetime difference of short- and long-lived $\rm B^0_s$ mesons has been obtained using an inclusive bottom hadron sample from 2 million hadronic Z decays collected by the L3 experiment at LEP. A lifetime fit has been performed on data samples separately enriched in neutral and charged b hadrons. An experimental upper limit on the decay rate difference of short- and long-lived $\rm B^0_s$ mesons of \begin{displaymath} ~~~~ {\rm (|\Delta\Gamma|/\Gamma)_{B^0_s}} < 0.67 ~~~~~~~\mathrm{(95\% \; C.L.)} \end{displaymath} has been determined. In addition, the lifetimes of $\rm B^+$ and $\rm B^0_d$ mesons have been measured to be $\tau(\rm B^+) = 1.66 \pm 0.06 \, \pm 0.03 \; \mathrm{ps}$ and $\tau(\rm B^0_d) = 1.52 \pm 0.06 \, \pm 0.04 \; \mathrm{ps}$, where the first errors are statistical and the second are systematic.

Abstract: We have searched for evidence of Upsilon production in 3.5 million hadronic Z decays collected by the L3 detector at LEP in 1991-1995. No signals are observed for the decay chain Z -> Upsilon X; Upsilon -> l+l- (l= e, mu), therefore upper limits at the 95% confidence level are set on the following Z branching fractions: BR (Z -> Upsilon(1S) X) < 5.5 x 10**-5; BR (Z -> Upsilon(2S) X) < 13.9 x 10**-5; BR (Z -> Upsilon(3S) X) < 9.4 x 10**-5.

Abstract: We describe the sample of energetic single-photon events (Eγ > 15 GeV) collected by L3 in the 1991–1993 LEP runs. The event distributions agree with expectations from the Standard Model. The data are used to constrain the ZZγ coupling and to set an upper limit of 4.1 × 10−6, μB (90% C.L.) on the the magnetic moment of the τ neutrino., Facultad de Ciencias Exactas

Abstract: We have measured the branching fractions for the hadronic τ decays, τ→π/Knπ°v (0 ≤ n ≤ 3), with the L3 detector at LEP. Multiphoton final states are analyzed using the fine-grained, high-resolution electromagnetic calorimeter. The decay channels are identified using a neural network method. The results are: BR(τ→π/Kv) = (11.82 ± 0.26 ± 0.43)%, BR (τ→π/Kπ°v) = (25.05 ± 0.35 ± 0.50)%, BR(τ→π/ K2π°v) = (8.88 ± 0.37 ± 0.42)%, BR(τ→π/K3π°v) = (1.70 ± 0.24 ± 0.38)%, where the first error quoted is statistical, the second systematic., Facultad de Ciencias Exactas
