Abstract: International audience; Precise knowledge of the charge and rigidity dependence of the secondary cosmic ray fluxes and the secondary-to-primary flux ratios is essential in the understanding of cosmic ray propagation. We report the properties of heavy secondary cosmic ray fluorine F in the rigidity $R$ range 2.15 GV to 2.9 TV based on 0.29 million events collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The fluorine spectrum deviates from a single power law above 200 GV. The heavier secondary-to-primary F/Si flux ratio rigidity dependence is distinctly different from the lighter B/O (or B/C) rigidity dependence. In particular, above 10 GV, the $^{\textrm{F/Si}}_{\textrm{B/O}}$ ratio can be described by a power law $R^δ$ with $δ=0.052±0.007$. This shows that the propagation properties of heavy cosmic rays, from F to Si, are different from those of light cosmic rays, from He to O, and that the secondary cosmic rays have two classes.

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: 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: The Alpha Magnetic Spectrometer (AMS) is a large acceptance (0.65 sr m(2)) detector designed to operate in the International Space Station (ISS) for three years. The purposes of the experiment are to search for cosmic antimatter and dark matter and to study the composition and energy spectrum of the primary cosmic rays. A "scated-down" version has been flown on the Space Shuttle Discovery for 10 days in June 1998. The complete AMS is programmed for installation on the ISS in October 2003 for an operational period of 3 yr. This contribution reports on the experimental configuration that will be installed on the ISS. (C) 2002 Elsevier Science B.V. All rights reserved.

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: 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: Four of the Michel parameters and the average tau-neutrino helicity have been measured by analysing tan decay spectra in 147 pb(-1) of data collected by the L3 detector. The decays tau(-) --> e(-)nu(tau)(e), tau(-) --> mu(-)nu(tau)(mu), tau(-) --> pi(-)nu(tau), tau(-) --> rho(-)nu(tau) and their charge conjugates were considered. The results: rho = 0.762 +/- 0.035, eta = 0.27 +/- 0.14, xi = 0.70 +/- 0.16, xi delta = 0.70 +/- 0.11 and xi(h) = -1.032 +/- 0.031 are consistent with a V-A structure for the weak charged current and lepton universality, (C) 1998 Elsevier Science B.V.

Abstract: We have searched for neutralinos produced via the reactions e+e− → χχ′ and e+e−→ χ′χ′, where the next-to lightest neutralino, χ′, decays into the lightest neutralino, χ, and either a photon or a fermion pair. Based on 1.8 × 106 hadronic Z decays collected with the L3 detector at LEP, no signal has been observed. We present upper limits of a few times 10−5 on the branching ratios Z → χχ′ and Z → χ′χ′. In the framework of the Minimial Supersymmetric Standard Model, we exclude a lightest χ with mχ less than 18 GeV, if either tan β > 2 or the gluino mass m≈g > 100 GeV., Facultad de Ciencias Exactas

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: We have searched for lepton flavour violation in Z0 boson decays into lepton pairs, Z0→μτ, Z0→eτ, and Z0→eμ. The data sample is based on an integrated luminosity of 10.4 pb-1 corresponding to 370 000 Z0’s produced. We obtain upper limits on the branching ratios of 4.8 X 10-5 for the μτ 3.4 X 10-5 for the eτ and 2.4 X 10-5 for the eμ decay modes at the 95% confidence level., Facultad de Ciencias Exactas

Abstract: We have studied the reactions e+e−→hadrons, e+e−, μ+ μ− and τ+τ−, in the energy range 88.2 ≦ √s ≦ 94.2 GeV. A total luminosity of 5.5 pb−1, corresponding to approximately 115000 hadronic and 10000 leptonic Z0 decays, has been recorded with the L3 detector. From a simultaneous fit to all of our measured cross section data, we obtain assuming lepton universality: Mz = 91.181 ± 0.010 ± 0.02 (LEP) GeV, Γz = 2501 ± 17 MeV, Γhad= 1742 ± 19 MeV, Γt = 83.6 ± 0.8 MeV. If we do not assume lepton universality, we obtain for the partial decay widths of the Z0 into e+e−, μ+μ− and τ+ τ−: Γe = 83.3 ± 1.1 MeV, Γμ = 84.5 ± 2.0 MeV, Γτ = 84.0 ± 2.7 MeV. From the measured ratio of the invisible and the leptonic decay widths of the Z0, we determine the number of light neutrino species to be Nv =3.05±0.10. We include our measurements of the forward-backward asymmetry for the leptonic channels in a fit to determine the vector and axial-vector neutral current coupling constants of charged leptons to the Z0. We obtain g¯V = −0.046+0.015−0.012 and g¯A = −0.500 ± 0.003. In the framework of the Standard Model, we estimate the top quark mass to be mt =193+52−69 ± 16 (Higgs) GeV, and we derive a value for the weak mixing angle of sin2θW ≡ 1 − (MW/MZ)2 = 0.222 ± 0.008, corresponding to an effective weak mixing angle of sin2θ¯W = 0.2315 ± 0.0025., Facultad de Ciencias Exactas

Abstract: If simplified, every information retrieval problem can be solved when the information need implied by its expression has been identified. We are interested in the criteria used in realising a good information retrieval problem expression. We have listed these criteria through some principles and maxims which first characterized the communication between two persons are applied. We choose to use the gricean maxims because they are the most favoured for this type of situation. Secondly, we have tried to identify some others principles that can be used to realise a good information retrieval problem expression. The principles by Grice can not resolve all forms of error associated with this particular form of communication. In our work, we defined three other principles namely: adhesion principle, reformulation principle, memorization principle. We give some examples of situations where the principles we have formulated are not applicable and the consequences. We present the possible applications of our new model: MIRABEL, which can help in the description of information retrieval problem from. It also compels its user to use essential good expression principle implicitly.

Abstract: We have searched for the excited electron neutrino produced from Z 0 decays in the channel e + e − →νν ∗ using the L3 detector at LEP. The decays ν ∗ →eW and ν ∗ →νγ have been investigated. We have determined an upper limit on the Zνν ∗ coupling as a function of m ν ∗ up to the Z 0 mass.

Abstract: We have measured the partial widths for the three reactions e + e − → Z 0 → e + e − , μ + μ − , τ + τ − . The results are Γ ee = 84.3±1.3 MeV, √ Γ ee Γ μμ =83.9±1.4 MeV, and √ Γ ee Γ ττ =83.9±1.4 MeV, where the errors are statistical. The systematic errors are estimated to be 1.0 MeV, 0.9 MeV, and 1.4 MeV, respectively. We perform a simultaneous fit to the cross sections for the e + e − →e + e − , μ + μ − , and τ + τ − data, the differential cross section as a function of polar angle for the electron data, and the forward- backward asymmetry for the muon data. We obtain the leptonic partial with Γ ll =84.0±0.9 (stat.) MeV. The systematic error is estimated to be 0.8 MeV. Also, we obtain the axial-vector and vector weak coupling constants of charged leptons, g A =−0.500±0.003 and g ν =−0.064 −0.013 +0.017 .

Abstract: The reactions gamma gamma -> pi^+pi^-pi^+pi^- and gamma gamma -> pi^+pi^0pi^-pi^0 are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161GeV to 209GeV with a total integrated luminosity of 698/pb. A spin-parity-helicity analysis of the rho^0 rho^0 and rho^+ rho^- systems for two-photon centre-of-mass energies between 1GeV and 3GeV shows the dominance of the spin-parity state 2+ with helicity 2. The contribution of 0+ and 0- spin-parity states is also observed, whereas contributions of 2- states and of a state with spin-parity 2+ and zero helicity are found to be negligible. The reactions γγ→π+π−π+π− and γγ→π+π0π−π0 are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161 GeV to 209 GeV with a total integrated luminosity of 698 pb −1 . A spin-parity-helicity analysis of the ρ0ρ0 and ρ+ρ− systems for two-photon centre-of-mass energies between 1 and 3 GeV shows the dominance of the spin-parity state 2+ with helicity 2. The contribution of 0+ and 0− spin-parity states is also observed, whereas contributions of 2− states and of a state with spin-parity 2+ and zero helicity are found to be negligible. The reactions gamma gamma -> pi^+pi^-pi^+pi^- and gamma gamma -> pi^+pi^0pi^-pi^0 are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161GeV to 209GeV with a total integrated luminosity of 698/pb. A spin-parity-helicity analysis of the rho^0 rho^0 and rho^+ rho^- systems for two-photon centre-of-mass energies between 1GeV and 3GeV shows the dominance of the spin-parity state 2+ with helicity 2. The contribution of 0+ and 0- spin-parity states is also observed, whereas contributions of 2- states and of a state with spin-parity 2+ and zero helicity are found to be negligible.

Abstract: Aims. Several experiments have reported observations on possible correlations between the flux of high energy muons and intense solar flares. If confirmed, these observations would have significant implications for acceleration processes in the heliosphere able to accelerate protons and other ions to energies of at least tens of GeV. Methods. The solar flare of the 14 of July 2000 offered a unique opportunity for the L3+C experiment to search for a correlated enhancement in the flux of muons using the L3 precision muon spectrometer. Its capabilities for observing a directional excess in the flux of muons above 15 GeV (corresponding to primary proton energies above 40 GeV) are presented along with observations made on the 14th of July 2000. Results. We report an excess which appeared at a time coincident with the peak increase of solar protons observed at lower energies. The probability that the excess is a background fluctuation is estimated to be 1 %. No similar excess of the muon flux was observed up to 1.5 h after the solar flare time. © ESO 2006.
