Abstract: The AMS experiment includes a Cherenkov imager for mass and charge identification of charged cosmic rays. A second generation prototype has been constructed and its performances evaluated both with cosmic ray particles and with beam ions. In-beam tests have been performed using secondary nuclei from the fragmentation of 20 GeV/c per nucleon Pb ions and 158 GeV/c per nucleon In from the CERN SPS in 2002 and 2003. Partial results are reported. The performances of the prototype for the velocity and the charge measurements have been studied over the range of ion charge Z less, approximate 30. A sample of candidate silica aerogel radiators for the flight model of the detector has been tested. The measured velocity resolution of the detector was found to scale with $Z^{-1}$ as expected, with a value σ(β)/β≈0.7–110^{-3} for singly charged particles and an asymptotic limit in Z of 0.4–0.6×10^{-4}. The measured charge resolution obtained for the n=1.05 aerogel radiator material selected for the flight model of the detector is σ(Z)=0.18 (statistical) circle plus operator 0.015 (systematic), ensuring a good charge separation up to the iron element, for the prototype in the reported experimental conditions.

Abstract: The double-radiative process e+e− → Zγγ → q ̄qγγ where the two hard photons escape detection at low polar angles into opposite directions, is studied in 0.62 fb−1 of data collected with the L3 detector at LEP at centre-of-mass energies between 188.6 and 209.2 GeV. The cross sections are measured and found to be consistent with the Standard Model expectations., Facultad de Ciencias Exactas

Abstract: Inclusive jet production, e+e− → e+e− jet X, is studied using 560 pb−1 of data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 209 GeV. The inclusive differential cross section is measured using a kt jet algorithm as a function of the jet transverse momentum, pt, in the range 3 < pt < 50 GeV for a pseudorapidity, η, in the range −1 pt , the measured cross section is significantly higher than the NLO QCD predictions, as already observed for inclusive π± and π0 production., Facultad de Ciencias Exactas

Abstract: A search for a Higgs boson produced in e+e− collisions in association with a Z boson and decaying into invisible particles is performed. Data collected at LEP with the L3 detector at centre-of-mass energies from 189 to 209 GeV are used, corresponding to an integrated luminosity of 0.63 fb−1. Events with hadrons, electrons or muons with visible masses compatible with a Z boson and missing energy and momentum are selected. They are consistent with the Standard Model expectations. A lower limit of 112.3 GeV is set at 95% confidence level on the mass of the invisibly-decaying Higgs boson in the hypothesis that its production cross section equals that of the Standard Model Higgs boson. Relaxing this hypothesis, upper limits on the production cross section are derived., Facultad de Ciencias Exactas

Abstract: A flavour independent search for the CP-even and CP-odd neutral Higgs bosons h and A is performed in 624 pb−1 of data collected with the L3 detector at LEP at centre-of-mass energies between 189 and 209 GeV. Higgs boson production through the e+e− → Zh and the e+e− → hA processes is considered and decays of the Higgs bosons into hadrons are studied. No significant signal is observed and 95% confidence level limits on the hZZ and hAZ couplings are derived as a function of the Higgs boson masses. Assuming the Standard Model cross section for the Higgs-strahlung process and a 100% branching fraction into hadrons, a 95% confidence level lower limit on the mass of the Higgs boson is set at 110.3 GeV., Facultad de Ciencias Exactas

Abstract: The cross section of W-boson pair-production is measured with the L3 detector at LEP. In a data sample corresponding to a total luminosity of 629.4 pb−1, collected at centre-of-mass energies ranging from 189 to 209 GeV, 9834 four-fermion events with W bosons decaying into hadrons or leptons are selected. The total cross section is measured with a precision of 1.4% and agrees with the Standard Model expectation. Assuming charged-lepton universality, the branching fraction for hadronic W-boson decays is measured to be: Br(W → hadrons) = 67.50 ± 0.42(stat.) ± 0.30(syst.)%, in agreement with the Standard Model. Differential cross sections as a function of the W-production angle are also measured for the semi-leptonic channels qqeν and qqμν., Facultad de Ciencias Exactas

Abstract: Single- and multi-photon events with missing energy are selected in 619 pb−1 of data collected by the L3 detector at LEP at centre-of-mass energies between 189 and 209 GeV. The cross sections of the process e+e−→ν ̄νγ (γ ) are found to be in agreement with the Standard Model expectations, and the number of light neutrino species is determined, including lower energy data, to be Nν=2.98±0.05±0.04. Selection results are given in the form of tables which can be used to test future models involving single- and multi-photon signatures at LEP. These final states are also predicted by models with large extra dimensions and by several supersymmetric models. No evidence for such models is found. Among others, lower limits between 1.5 and 0.65 TeV are set, at 95% confidence level, on the new scale of gravity for the number of extra dimensions between 2 and 6., Physics Letters B, 587 (1-2), ISSN:0370-2693, ISSN:0031-9163, ISSN:1873-2445

Abstract: Scalar partners of quarks and leptons, predicted in supersymmetric models, are searched for in e+e− collisions at centre-ofmass energies between 192 and 209 GeV at LEP. No evidence for any such particle is found in a data sample of 450 pb−1. Upper limits on their production cross sections are set and lower limits on their masses are derived in the framework of the Minimal Supersymmetric Standard Model., Facultad de Ciencias Exactas

Abstract: A Higgs particle produced in association with a Z boson and decaying into weak boson pairs is searched for in 336.4 pb−1 of data collected by the L3 experiment at LEP at centre-of-mass energies from 200 to 209 GeV. Limits on the branching fraction of the Higgs boson decay into two weak bosons as a function of the Higgs mass are derived. These results are combined with the L3 search for a Higgs boson decaying to photon pairs. A Higgs produced with a Standard Model e+e− → Zh cross section and decaying only into electroweak boson pairs is excluded at 95% CL for a mass below 107 GeV., Facultad de Ciencias Exactas

Abstract: The cross section of the process e+e- → Ze+e- is measured with 0.7 fb-1 of data collected with the L3 detector at LEP. Decays of the Z boson into quarks and muons are considered at centre-of-mass energies ranging from 183 GeV up to 209 GeV. The measurements are found to agree with Standard Model predictions, achieving a precision of about 10% for the hadronic channel., Physics Letters B, 561 (1-2), ISSN:0370-2693, ISSN:0031-9163, ISSN:1873-2445

Abstract: A search for colour reconnection effects in hadronic decays of W pairs is performed with the L3 detector at centre-of-mass energies between 189 and 209 GeV. The analysis is based on the study of the particle flow between jets associated to the sameW boson and between two different W bosons in qqqq events. The ratio of particle yields in the different interjet regions is found to be sensitive to colour reconnection effects implemented in some hadronization models. The data are compared to different models with and without such effects. An extreme scenario of colour reconnection is ruled out., Physics Letters B, 561 (3-4), ISSN:0370-2693, ISSN:0031-9163, ISSN:1873-2445

Abstract: Inclusive charged hadron production, e+e− → e+e−h±X, is studied using 414 pb−1 of data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 202 GeV. Single particle inclusive differential cross sections are measured as a function of the particle transverse momentum, pt , and pseudo-rapidity, η. For pt 1.5 GeV, the data are well described by an exponential, typical of soft hadronic processes. For higher pt , the onset of perturbative QCD processes is observed. The π± production cross section for pt > 5 GeV is much higher than the NLO QCD predictions., Facultad de Ciencias Exactas

Abstract: Events stemming from the pair-production of Z bosons in e+e− collisions are studied using 217.4 pb−1 of data collected with the L3 detector at centre-of-mass energies from 200 GeV up to 209 GeV. The special case of events with b quarks is also investigated. Combining these events with those collected at lower centre-of-mass energies, the Standard Model predictions for the production mechanism are verified. In addition, limits are set on anomalous couplings of neutral gauge bosons and on effects of extra space dimensions., Facultad de Ciencias Exactas

Abstract: Doubly-charged Higgs bosons are searched for in e+e− collision data collected with the L3 detector at LEP at centre-of-mass energies up to 209 GeV. Final states with four leptons are analysed to tag the pair-production of doubly-charged Higgs bosons. No significant excess is found and lower limits at 95% confidence level on the doubly-charged Higgs boson mass are derived. They vary from 95.5 to 100.2 GeV, depending on the decay mode. Doubly-charged Higgs bosons which couple to electrons would modify the cross section and forward–backward asymmetry of the e+e− →e+e− process. The measurements of these quantities do not deviate from the Standard Model expectations and doubly-charged Higgs bosons with masses up to the order of a TeV are excluded., Facultad de Ciencias Exactas

Abstract: The charged-particle multiplicity distribution is measured for all hadronic events as well as for light-quark and b-quark events produced in e+e− collisions at the Z pole. Moments of the charged-particle multiplicity distributions are calculated. The Hq moments of the multiplicity distributions are studied, and their quasi-oscillations as a function of the rank of the moment are investigated., 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 τ longitudinal polarisation has been measured as a function of the production polar angle using the τ decays τ−→h−ντ (h=π,ρ,a1) and τ−→ℓ−ν̄ℓντ (ℓ=e,μ). From this measurement the quantities Ae and Aτ, which depend on the couplings of the electron and the τ to the Z, are determined to be Ae=0.1678±0.0127±0.0030 and Aτ=01540±0.0088±0.0062, consistent with the hypothesis of e–τ universality. Under this assumption a value of Aℓ=0.1540±0.0074±0.0044 is obtained, yielding the value of the effective weak mixing angle sin2θW=0.2306±0.0011. Facultad de Ciencias Exactas

Abstract: Single W boson production in electron–positron collisions is studied with the L3 detector at centre-of-mass energies between 192 GeV and 209 GeV. Events with two acoplanar hadronic jets or a single energetic lepton are selected, and the single W cross section is measured. Combining the results with measurements at lower centre-of-mass energies, the ratio of the measured cross section to the Standard Model expectation is found to be 1.12+0.11−0.10± 0.03. From all single W data, the WWγ gauge coupling parameter κγ is measured to be 1.116+0.082−0.086± 0.068., Facultad de Ciencias Exactas

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 β for several scenarios. For tan β greater than 0.7 they are mh > 84.5 GeV and mA > 86.3 GeV at 95% confidence level., Facultad de Ciencias Exactas

Abstract: Strange baryon pair production in two-photon collisions is studied with the L3 detector at LEP. The analysis is based on data collected at e+e− centre-of-mass energies from 91 GeV to 208 GeV, corresponding to an integrated luminosity of 844 pb−1. The processes γ γ → ̄ and γ γ → 00 are identified. Their cross sections as a function of the γ γ centre-of-mass energy are measured and results are compared to predictions of the quark–diquark model., Facultad de Ciencias Exactas

Abstract: The process e+e− → W+W−γ is studied using the data collected by the L3 detector at LEP.

Abstract: The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle Discovery during flight STS-91 (June 1998) in a 51.7 deg orbit at altitudes between 320 and 390 km. A search for antihelium nuclei in the rigidity range 1–140 GV was performed. No antihelium nuclei were detected at any rigidity. An upper limit on the flux ratio of antihelium to helium of < 1.1×10^−6 was obtained. The high energy proton, electron, positron, helium, antiproton and deuterium spectra were accurately measured. For each particle and nuclei two distinct spectra were observed: a higher energy spectrum and a substantial second spectrum. Positrons in the second spectrum were found to be much more abundant than electrons. Tracing particles from the second spectra shows that most of them travel for an extended period of time in the geomagnetic field, and that the positive particles (p and e+) and negative ones (e−) originate from two complementary geographic regions. The second helium spectrum flux over the energy range 0.1–1.2 GeV/nucleon was measured to be (6.3 ± 0.9) × 10^−3(m^2 s sr)^−1. Over 90 percent of the helium flux was determined to be 3He at the 90% confidence level

Abstract: Single top production in e+e− annihilations is searched for in data collected by the L3 detector at centre-of-mass energies from 189 to 209 GeV, corresponding to a total integrated luminosity of 634 pb−1. Investigating hadronic and semileptonic top decays, no evidence of single top production at LEP is obtained and upper limits on the single top cross section as a function of the centre-of-mass energy are derived. Limits on possible anomalous couplings, as well as on the scale of contact interactions responsible for single top production are determined., Facultad de Ciencias Exactas

Abstract: We measure three-particle Bose–Einstein correlations in hadronic Z decay with the L3 detector at LEP. Genuine three-particle Bose–Einstein correlations are observed. By comparing two- and three-particle correlations we find that the data are consistent with fully incoherent pion production., Facultad de Ciencias Exactas

Abstract: Inclusive D^{*+-} production in two-photon collisions is studied with the L3 detector at LEP, using 683 pb^{-1} of data collected at centre-of-mass energies from 183 to 208 GeV. Differential cross sections are determined as functions of the transverse momentum and pseudorapidity of the D^{*+-} mesons in the kinematic region 1 GeV < P_T < 12 GeV and |eta| < 1.4. The cross sections sigma(e^+e^- ---> e^+e^-D^{*+-}X)$ in this kinematical region is measured and the sigma(e^+e^- ---> e^+e^- cc{bar}X) cross section is derived. The measurements are compared with next-to-leading order perturbative QCD calculations. Inclusive D ∗± production in two-photon collisions is studied with the L3 detector at LEP, using 683 pb −1 of data collected at centre-of-mass energies from 183 to 209 GeV.

Abstract: The e+e− → e+e−K0 SK±π∓ and e+e− → e+e−ηπ+π− final states are studied with the L3 detector at LEP using data collected at centre-of-mass energies from 183 GeV up to 202 GeV. The mass spectrum of the K0 SK±π∓ final state shows an enhancement around 1470 MeV, which is identified with the pseudoscalar meson η(1440). This state is observed in γ γ collisions for the first time and its two-photon width is measured to be Γγ γ (η(1440)) × BR(η(1440) → KKπ ) = 212 ± 50 (stat.) ± 23 (sys.) eV. Clear evidence is also obtained for the formation of the axial vector mesons f1(1420) and f1(1285). In the ηπ+π− channel the f1(1285) is observed, and upper limits for the formation of η(1440) and η(1295) are obtained., Facultad de Ciencias Exactas

Abstract: We report on a search for the first generation heavy neutrino that is an isosinglet under the standard SU(2)L gauge group. The data collected with the L3 detector at center-of-mass energies between 130 GeV and 208 GeV are used. The decay channel Ne →eW is investigated and no evidence is found for a heavy neutrino, Ne, in a mass range between 80 GeV and 205 GeV. Upper limits on the mixing parameter between the heavy and light neutrino are derived., Facultad de Ciencias Exactas

Abstract: Final results of the search for the standard model Higgs boson are presented for the data collected by the L3 detector at LEP at centre-of-mass energies up to about 209 GeV. These data are compared with the expectations of standard model processes for Higgs boson masses up to 120 GeV. A lower limit on the mass of the standard model Higgs boson of 112.0 GeV is set at the 95% confidence level. The most significant high mass candidate is a Hν¯ν event. It has a reconstructed Higgs mass of 115 GeV and it was recorded at √s = 206.4 GeV., Facultad de Ciencias Exactas

Abstract: The K0S K0S final state in two-photon collisions is studied with the L3 detector at LEP. The mass spectrum is dominated by the formation of the f '2(1525) tensor meson in the helicity-two state with a two-photon width times the branching ratio into K K of 76 ± 6 ± 11 eV. A clear signal for the formation of the fJ(1710) is observed and it is found to be dominated by the spin-two helicity-two state. No resonance is observed in the mass region around 2.2 GeV and an upper limit of 1.4 eV at 95% C.L. is derived for the two-photon width times the branching ratio into K0 SK0 S for the glueball candidate ξ (2230)., Facultad de Ciencias Exactas

Abstract: The measurements of hadron and lepton-pair production cross sections and leptonic forward–backward asymmetries performed with the L3 detector at centre-of-mass energies between 130 GeV and 189 GeV are used to search for new physics phenomena such as: contact interactions, exchange of virtual leptoquarks, scalar quarks and scalar neutrinos, effects of TeV strings in models of quantum gravity with large extra dimensions and non-zero sizes of the fermions. No evidence for these phenomena is found and new limits on their parameters are set., Facultad de Ciencias Exactas

Abstract: A first measurement of the cross section of the process e+e−→Zγγ is reported using a total integrated luminosity of 231 pby1 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 eqeyTMZgg cross section is measured to be 0.49+0.20−0.17±0.04pb at 182.7 GeV and 0.47±0.10±0.04pb at 188.7 GeV. The measurements are consistent with Standard Model expectations. Limits on Quartic Gauge Boson Couplings aa0/Λ2 and ac/Λ2 of −0.009GeV−20/Λ2GeV−2 and −0.007GeV−2c/Λ2GeV−2 are derived at 95% confidence level., Facultad de Ciencias Exactas

Abstract: The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle Discovery during flight STS-91 in a 51.7 degree orbit at altitudes between 320 and 390 km. A total of 2.86 * 10^6 helium nuclei were observed in the rigidity range 1 to 140 GV. No antihelium nuclei were detected at any rigidity. An upper limit on the flux ratio of antihelium to helium of < 1.1 * 10^-6 is obtained., 18 pages, Latex, 9 .eps figures

Abstract: We report the result of a search for charginos and neutralinos, 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 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 a limit on the mass of the lightest chargino of 67.7 GeV for M2 < 2 TeV., Facultad de Ciencias Exactas

Abstract: The lepton spectra in the kinetic energy ranges 0.2 to 40 GeV for e − and 0.2 to 3 GeV for e + were measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS–91 at altitudes near 380 km. From the origin of the leptons two distinct spectra were observed: a higher energy spectrum and a substantial second spectrum with positrons much more abundant than electrons. Tracing leptons from the second spectra shows that most of these leptons travel for an extended period of time in the geomagnetic field and that the e + and e − originate from two complementary geographic regions.

Abstract: Small-angle Bhabha scattering data recorded at the Z resonance and large-angle Bhabha scattering data recorded at 's s189 GeV by the L3 detector at LEP are used to measure the running of the effective fine-structure constant for spacelike momentum transfers. The results are α−1(−2.1GeV2)−α−1(−6.25GeV2)=0.78±0.26 α−1(−12.25GeV2)−α−1(−3434GeV2)=3.80±1.29, in agreement with theoretical predictions., Facultad de Ciencias Exactas

Abstract: We have measured the probability, nga cc , of a gluon splitting into a charm-quark pair using 1.7 million hadronic Z decays collected by the L3 detector. Two independent methods have been applied to events with a three-jet topology. One method relies on tagging charmed hadrons by identifying a lepton in the lowest energy jet. The other method uses a neural network based on global event shape parameters. Combining both methods, we measure ng→cc̄=[2.45±0.29±0.53]%., Facultad de Ciencias Exactas

Abstract: The helium spectrum from 0.1 to 100 GeV/nucleon was measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS-91 at altitudes near 380 km. Above the geomagnetic cutoff the spectrum is parameterized by a power law. Below the geomagnetic cutoff a second helium spectrum was observed. In the second helium spectra over the energy range 0.1 to 1.2 GeV/nucleon the flux was measured to be (6.3±0.9)×10 −3 ( m 2 sec sr ) −1 and more than ninety percent of the helium was determined to be 3He (at the 90% CL). Tracing helium from the second spectrum shows that about half of the 3He travel for an extended period of time in the geomagnetic field and that they originate from restricted geographic regions similar to protons and positrons.

Abstract: The measurements of Rb=σ(e+e−→bb̄)/σ(e+e−→qq̄) and of the b quark forward–backward charge asymmetry, Abfb, at centre-of-mass energies above the Z pole are described. The measurement of Rb is performed at 's between 130 and 189 GeV using a b-tagging method that exploits the relatively large decay length of b-hadrons. The measurement of Ab is fb performed using the large statistics event sample collected at 's s189 GeV with a lepton-tag analysis based on the selection ' b of prompt muons and electrons. The results at s =189 GeV are Rb=0.163±0.013(stat.)±0.005(syst.), Afbb=0.61±0.18(stat.)±0.09(syst.), Facultad de Ciencias Exactas

Abstract: The structure functions of real and virtual photons are derived from cross section measurements of the reaction e e qy qy ae e q hadrons at LEP. The reaction is studied at 's ,91 GeV with the L3 detector. One of the final state electrons is detected at a large angle relative to the beam direction, leading to Q2 values between 40 GeV2 and 500 GeV2. The other final state electron is either undetected or it is detected at a four-momentum transfer squared P2 between 1 GeV2 and 8 GeV2 . These measurements are compared with predictions of the Quark Parton Model and other QCD based models., Facultad de Ciencias Exactas

Abstract: Anomalous couplings of the Higgs boson are searched for through the processes e+e− → Hγ , e+e− → e+e−H and e+e− → HZ. The mass range 70 GeV < mH < 190 GeV is explored using 602 pb−1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies √s = 189–209 GeV. The Higgs decay channels H → f ̄f, H → γγ , H → Zγ and H → WW(∗) are considered and no evidence is found for anomalous Higgs production or decay. Limits on the anomalous couplings d, dB, ΔgZ1, Δκγ and ξ2 are derived as well as limits on the H → γγ and H → Zγ decay rates., Facultad de Ciencias Exactas

Abstract: An S-Matrix ansatz is used to determine the mass and width of the Z boson, as well as the contributions of γ/Z interference and Z boson exchange to fermion-pair production. For this purpose we use hadron and lepton-pair production cross sections and lepton forward-backward asymmetries that have been measured with the L3 detector at centre-of-mass energies between 87 GeV and 189 GeV., Facultad de Ciencias Exactas

Abstract: The proton spectrum in the kinetic energy range 0.1 to 200 GeV was measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS-91 at an altitude of 380 km. Above the geomagnetic cutoff the observed spectrum is parameterized by a power law. Below the geomagnetic cutoff a substantial second spectrum was observed concentrated at equatorial latitudes with a flux ~ 70 m^-2 sec^-1 sr^-1. Most of these second spectrum protons follow a complicated trajectory and originate from a restricted geographic region., 19 pages, Latex, 7 .eps figures

Abstract: Inclusive production of D*± mesons in two-photon collisions was measured by the L3 experiment at LEP. The data were collected at a centre-of-mass energy s s189 GeV with an integrated luminosity of 176.4 pb-1 . Differential cross sections of the process e+e-→e+e-D*±X are determined as functions of the transverse momentum and pseudorapidity of the D*± mesons in the kinematic region 1GeVTD∗GeV and |ηD∗|. The cross section integrated over this phase space domain is measured to be 132 ± 22 (stat.) ± 26 (syst.) pb. The differential cross sections are compared with next-to-leading order perturbative QCD calculations., Facultad de Ciencias Exactas

Abstract: We measure the masses, decay widths and relative production rate of orbitally excited B mesons using 1.25 million hadronic Z decays recorded by the L3 detector. B-meson candidates are inclusively reconstructed and combined with charged pions produced at the primary event vertex. An excess of events above the expected background in the Bπ mass spectrum in the region 5.6–5.8 GeV is interpreted as resulting from the decay B∗∗u,d→B(∗)π), where B∗∗u,d denotes a mixture of l = 1 B-meson states containing a u or a d quark. A fit to the mass spectrum yields the masses and decay widths of the B1* and B2* spin states, as well as the branching fraction for the combination l = 1 states. In addition, evidence is presented for the existence of an excited B-meson state or mixture of states in the region 5.9–6.0 GeV., Facultad de Ciencias Exactas

Abstract: A search for unstable neutral and charged heavy leptons as well as for stable charged heavy leptons is performed at center-of-mass energies √ s = 183 and 189 GeV with the L3 detector at LEP. No evidence for their existence is found. We exclude neutral heavy leptons which couple to the electron, muon or tau family, of the Dirac type for masses below 92.4, 93.3 and 83.3 GeV, and of the Majorana type for masses below 81.8, 84.1 and 73.5 GeV, respectively. We exclude unstable charged heavy leptons for masses below 93.9 GeV for a wide range of the associated neutral heavy lepton mass. If the unstable charged heavy lepton decays to a light neutrino, we exclude masses below 92.4 GeV. The production of stable charged heavy leptons with mass less than 93.5 GeV is also excluded., Facultad de Ciencias Exactas

Abstract: A search for chargino and neutralino pair production in e+e- collisions at center-of-mass energies between 161 GeV and 183 GeV is performed under the assumptions that R-parity is not conserved and that only purely leptonic or hadronic R-parity violating decays are allowed. No signal is found in the data. Limits on the production cross sections, on the Minimal Supersymmetric Standard Model parameters and on the masses of the supersymmetric particles are derived., Facultad de Ciencias Exactas
