Abstract: HELMOD model allows one to describe how solar modulation affects the propagation of galactic cosmic rays (GCR) through the heliosphere with an accuracy of the level of actual experimental uncertainties. The GCRs mainly constitute the high energy population of the so-called space radiation environment. The model treats the physical processes involved in solar modulation, like diffusion, particle drift, convection and adiabatic energy losses, and it embeds a description of both the inner and outer heliosphere. To obtain the modulated intensities, the model requires the knowledge of a few time-dependent heliospheric quantities, i.e., sunspot number, tilt angle of the neutral current sheet, solar wind speed and density, and interplanetary magnetic field. Using historical records, we present a template-based procedure that allows one to predict the heliospheric parameters for coming years, and, in turn, the forecasted modulated spectra. The forecasting templates reconstruct the typical time variation along with solar cycles and may be tuned to the current solar cycle. We estimate that the uncertainty of the forecasted cosmic rays intensity is below 5% (±10% at 68% C.L.) on average for short time predictions (up to 4 years), and below 15% (±(20-25)% at 68% C.L.) for long time predictions (up to 11 years).

Abstract: HELMOD model allows one to describe how solar modulation affects the propagation of galactic cosmic rays (GCRs) through the heliosphere by solving the Parker transport equation. HELMOD provides modulated spectra for protons and nuclei during high and low solar activity periods, in the inner and outer heliosphere, at Earth location and outside the ecliptic plane, as well as at different distances from Sun in the inner and outer heliosphere. The GCRs mainly constitute the high-energy population of the so-called space radiation environment. Modulated cosmic-ray spectra of protons and nuclei, obtained from HELMOD and other solar modulation codes were compared to the AMS–02 spectra ranging from GeV up to TeV energies. Concerning other commonly used solar modulation models, HELMOD modulated spectra are available over the entire rigidity range and observation period of AMS–02 mission. A quantitative comparison among models was carried out using ΔΦ, i.e., the relative difference between the experimental and simulated fluences, and ηRMS, i.e., the error-weighted root mean square of the relative difference between AMS–02 experimental data and simulated differential intensities. HELMOD was found to achieve a good agreement over the full set of experimental data with, typically, ΔΦ within ±2.5% and ηRMS within 5%. Usually larger or, in a few cases, much larger values for ΔΦ and ηRMS were found for the other models.

Abstract: The absolute muon flux between 20 and 3000 GeV is measured with the L3 magnetic muon spectrometer for zenith angles ranging from 0°to 58°. Due to the large exposure of about 150 m2sr d, and the excellent momentum resolution of the L3 muon chambers, a precision of 2.3% at 150 GeV in the vertical direction is achieved.The ratio of positive to negative muons is studied between 20 and 500 GeV, and the average vertical muon charge ratio is found to be 1.285±0.003(stat.)±0.019(syst.)., Physics Letters B, 598 (1-2), ISSN:0370-2693, ISSN:0031-9163, ISSN:1873-2445

Abstract: Events from the e+e− → Zγ process with hard initial-state radiation collected with the L3 detector at centre-of-mass energies between 183 and 209 GeV are used to measure the mass of the Z boson. Decays of the Z boson into hadrons or muon pairs are considered and the Z mass is determined to be 91.272 ± 0.032(stat) ± 0.033(syst) GeV, in agreement with the value measured at the Z resonance. Alternatively, assuming this measured value of the Z mass, the method determines the LEP centre-of-mass energy, found to be 175 ± 68(stat) ± 68(syst) MeV lower than the nominal value., Facultad de Ciencias Exactas

Abstract: A search is performed in symmetric 3-jet hadronic Z-decay events for evidence of colour singlet production or colour reconnection effects. Asymmetries in the angular separation of particles are found to be sensitive indicators of such effects. Upper limits on the level of colour singlet production or of colour reconnection effects are established for a variety of models., Facultad de Ciencias Exactas

Abstract: The reaction e+e- -> e+e- proton antiproton is studied with the L3 detector at LEP. The analysis is based on data collected at e+e- center-of-mass energies from 183 GeV to 209 GeV, corresponding to an integrated luminosity of 667 pb-1. The gamma gamma -> proton antiproton differential cross section is measured in the range of the two-photon center-of-mass energy from 2.1 GeV to 4.5 GeV. The results are compared to the predictions of the three-quark and quark-diquark models. The reaction e^+e^- -> e^+e^- proton antiproton is studied with the L3 detector at LEP. The analysis is based on data collected at e^+e^- center-of-mass energies from 183 GeV to 209 GeV, corresponding to an integrated luminosity of 667 pb^-1. The gamma gamma -> proton antiproton differential cross section is measured in the range of the two-photon center-of-mass energy from 2.1 GeV to 4.5 GeV. The results are compared to the predictions of the three-quark and quark-diquark models. The reaction e + e − → e + e − p p ̄ is studied with the L3 detector at LEP. The analysis is based on data collected at e + e − center-of-mass energies from 183 GeV to 209 GeV, corresponding to an integrated luminosity of 667 pb −1 . The γγ→ p p ̄ differential cross section is measured in the range of the two-photon center-of-mass energy from 2.1 to 4.5 GeV. The results are compared to the predictions of the three-quark and quark–diquark models.

Abstract: The process e + e − → Z γγ→ q q γγ is studied in 0.5 fb−1 of data collected with the L3 detector at centre-of-mass energies between 130.1 GeV and 201.7 GeV. Cross sections are measured and found to be consistent with the Standard Model expectations. The study of the least energetic photon constrains the quartic gauge boson couplings to −0.008 GeV−2

Abstract: We report on measurements of the inclusive production rate of Σ+ and Σ0 baryons in hadronic Z decays collected with the L3 detector at LEP. The Σ+ baryons are detected through the decay Σ+→pπ0, while the Σ0 baryons are detected via the decay mode Σ0→Λγ. The average numbers of Σ+ and Σ0 per hadronic Z decay are measured to be: NΣ++NΣ̄+=0.114±0.011stat±0.009syst NΣ0+NΣ̄0=0.095±0.015stat±0.013syst. These rates are found to be higher than the predictions from Monte Carlo hadronization models and analytical parameterizations of strange baryon production., Facultad de Ciencias Exactas

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: Searches for scalar top and scalar bottom quarks, as well as for mass-degenerate scalar quarks of the first two families are performed at 189 GeV centre-of-mass energy with the L3 detector at LEP. No signals are observed. Model-independent limits on the scalar top production cross sections are determined for the decay modes $\rm \tilde{t}_1 \rightarrow c \tilde{\chi}_1^0$ and $\rm \tilde{t}_1 \rightarrow b \ell \tilde{\nu}$. For scalar quarks of the other flavours $\tilde{\mathrm{q}} \to \mathrm{q} \tilde{\chi}_1^0$ decays are considered. Within the framework of the Minimal Supersymmetric Standard Model mass limits are set at 95\% C.L. for these particles. Indirect limits on the gluino mass are also derived.

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: We present a study of the structure of hadronic events recorded by the L3 detector at LEP at the center of mass energies of 161 and 172 GeV. The data sample corresponds to an integrated luminosity of 21.25 pb-1 collected during the high energy runs of 1996. The distributions of event shape variables and the energy dependence of their mean values are well reproduced by QCD models. From a comparison of the data with resummed second order QCD calculations, we determine the strong coupling constant at the two energies. Combining with our earlier measurements we find that the strong coupling constant decreases with increasing energy as expected in QCD.

Abstract: A search for excited leptons $\rm e^*,~\mu^*, ~\tau^*$ and $\nu_{\rm e}^*$ in $\rm e^+e^-$ collisions at $\rm \sqrt{s}$ = 161 GeV is performed using the $\rm 10.8 ~pb^{-1}$ of data collected by the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected $\ell^*\ell^*$ pair production in the channels $\rm ee\gamma\gamma$, $\rm \mu\mu\gamma\gamma$, $\rm \tau\tau\gamma\gamma$, $\rm eeWW$, and $\rm \nu\nu\gamma\gamma$, the lower mass limits at 95\% C.L. are 79.7 GeV for $\rm e^{*}$, 79.9 GeV for $\mu^{*}$, 79.3 GeV for $\tau^{*}$ and 71.3 GeV for $\nu_{\rm e}^{*}$ assuming the same couplings as for standard leptons. From an analysis of the expected $\ell\ell^*$ single production in channels $\rm ee\gamma$, $\mu\mu\gamma$, $ \tau\tau\gamma$, $\rm \nu_{e}eW$ and $\nu\nu\gamma$, the upper limits on the couplings $\lambda/m_{\ell^*}$ up to $m_{\ell^{*}}$ = 161 GeV are determined.

Abstract: A search for unstable sequential neutral and charged heavy leptons has been made at center-of-mass energies 130 and 136 GeV with the L3 detector at LEP. The neutral leptons are assumed to decay via mixing to electrons and muons. No evidence for their existence was found. We exclude unstable Dirac neutrinos for masses below 59.3 (57.9) GeV and unstable Majorana neutrinos below 48.6 (47.2) GeV if the neutrino couples to the electron(muon) family. We exclude unstable charged heavy leptons for masses below 61 GeV for a wide range of the associated neutral lepton mass.

Abstract: A search for supersymmetric particles (charginos, neutralinos, sleptons and stop quarks) has been performed with data collected by the L3 detector during the November 1995 run of the LEP collider at centre of mass energies between 130 and 140 GeV with a total integrated luminosity of 5.1 pb−1. We observe no signal for supersymmetric particles and we set improved exclusion limits on their production cross sections and masses.

Abstract: Using the data recorded with the L3 detector at LEP, we study the process e + e − → μ + μ − ( γ ) for events with hard initial-state photon radiation. The effective centre-of-mass energies of the muons range from 50 GeV to 86 GeV. The data sample corresponds to an integrated luminosity of 103.5 pb −1 and yields 293 muon-pair events with a hard photon along the beam direction. The events are used to determine the cross sections and the forward-backward charge asymmetries at centre-of-mass energies below the Z resonance.

Abstract: We report on a search for the excited leptons e ∗ , μ ∗ , τ ∗ and ν ∗ in e + e − collisions at s = 130-140 GeV using the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected pair produced l ∗ l ∗ in the channels eeγγ, μμγγ, ττγγ, eeWW, and ννγγ, we determine the lower mass limits at 95% C.L. of 64.7 GeV for e ∗ , 64.9 GeV for μ ∗ , 64.2 GeV for τ ∗ , 57.3 GeV (eW decay mode) and 61.4 GeV (νγ decay mode) for ν ∗ . From an analysis of the expected singly produced ll ∗ in the channels eeγ, μμγ, ττγ, νeW and ννγ, we determine upper limits on the couplings λ m l ∗ up to m l ∗ = 130 GeV .

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

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: 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: 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: 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 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: 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: Local multiplicity fluctuations in hadronic Z decays are studied using the L3 detector at LEP. Bunching parameters are used for the first time in addition to the normalised factorial moment method. The bunching parameters directly demonstrate that the fluctuations in rapidity are multifractal. Monte Carlo models show agreement with the data, reproducing the trend, although not always the magnitude, of the factorial moments and bunching parameters., Facultad de Ciencias Exactas

Abstract: We report on the measurement of W-boson pair-production with the L3 detector at LEP at an average centre-of-mass energy of 172.13 GeV. In a data sample corresponding to a total luminosity of 10.25 pb−1 we select 110 four-fermion events with pairs of hadronic jets or leptons with high invariant masses. Branching fractions of W decays into different fermion-antifermion pairs are determined with and without the assumption of charged-current lepton universality. The branching fraction for hadronic W decays is measured to be: B(W → hadrons) = 64.2+3.7−3.8 (stat.) ± 0.5 (syst.) %. Combining all final states the total cross section for W-pair production is measured to be: σWW = 12.27+1.41−1.32 (stat.) ± 0.23 (syst.) pb. The results are in good agreement with the Standard Model., Facultad de Ciencias Exactas

Abstract: The two-photon collision reaction e+e- → e+e- l+l- has been studied at √s ≈ 91 GeV using the L3 detector at LEP for l = e, μ, τ. We have analysed untagged configurations where the two photons are quasi-real. Good agreement is found between our measurements and the O(α4) QED expectation., Facultad de Ciencias Exactas

Abstract: A search for the neutral Higgs boson in the processes e(+)e(-) --> Z --> H-0 gamma --> and e(+)e(-) --> Z --> Z*H-0 --> has been performed using 2.8 million hadronic Z decays collected with the L3 detector at LEP from 1991 through 1994. No evidence for these processes has been observed. Upper limits at 95% confidence level for the corresponding cross sections have been set and the results have been compared with theoretical predictions beyond the Standard Model.

Abstract: We report on measurements of e+e− annihilation into hadrons and lepton pairs. The data have been collected with the L3 detector at LEP at centre-of-mass energies between 130 and 189 GeV. Using a total integrated luminosity of 243.7 pb−1, 25864 hadronic and 8573 lepton-pair events are selected for the measurement of cross sections and leptonic forward-backward asymmetries. The results are in good agreement with Standard Model predictions.

Abstract: The results of the searches for neutral Higgs boson production in the process e + e − → Z ∗ H 0 are reported, focusing on Higgs boson masses below 70 GeV. The data sample consists of three million hadronic Z 0 decays collected by the L3 experiment at LEP from 1991 through 1994. No signal is found leading to a lower limit on the mass of the Standard Model Higgs boson of 60.2 GeV at 95% C.L. These results are also interpreted in the framework of the General Two Doublet Model and limits on the nonstandard Higgs boson production through the process e + e − → Z ∗ h 0 are set. A lower limit of 66.7 GeV at 95% C.L. is obtained for the case where the Higgs decays into an invisible final state.

Abstract: Within a context of evolution and the rapid integration of digitization in university publishing, the fields of the humanities and social sciences, and in particular those of textbooks, do not appear to have found a satisfactory distribution model. In this article, we shall attempt to explain in what measure this sector is different from other areas of university publishing and what hypotheses can be put forward for its future development. Having suggested a carving up of the university publishing market, we would like to place it briefly in an international context. On the basis of this finding, we will present the hypothesis of aggregation: why this should be required, why it does not yet exist and which needs it will respond to. We shall conclude by summarizing these points which we believe are key to the development of a digital university offer in France for the humanities and social sciences.

Abstract: Using the data collected by the L3 experiment at LEP from 1991 to 1995 at energies around the Z mass, a measurement of the weak anomalous magnetic dipole moment, awτ, and of the weak electric dipole moment, dwτ, of the τ lepton is performed. These quantities are obtained from angular distributions in e+e−→τ+τ−→h+ν̄τh−ντ, where h is a π or a p. The results are: Re(awτ)=(0.0±1.6±2.3)×10−3, Im(awτ)=(−1.0±3.6±4.3)×10−3 and Re(dwτ)=(−0.44±0.88±1.33)×10−17e·cm. This is the first direct measurement of awτ., Facultad de Ciencias Exactas

Abstract: The inclusive production of 77 mesons has been studied using 1.6 million hadronic Z decays collected with the L3 detector. The q multiplicity per event, the multiplicity for two-jet and three-jet events separately, and the multiplicity in each jet have been measured and compared with the predictions of different Monte Carlo programs. The momentum spectra of 7,1 in each jet have also been measured. We observe that the measured v momentum spectrum in quark-enriched jets agrees well with the Monte Carlo prediction while in gluon-enriched jets it is harder than that predicted by the Monte Carlo models., Facultad de Ciencias Exactas

Abstract: The process e(+)e(-) --> Zgamma, where the Z boson decays into hadrons or neutrinos, is studied with data collected with the L3 detector at LEP at centre-of-mass energies from 189 up to 209 GeV The cross sections are measured and found to be in agreement with the Standard Model predictions. Limits on triple neutral-gauge-boson couplings, forbidden in the Standard Model at tree level, are derived. Limits on the energy scales at which the anomalous couplings could be manifest are set. They range from 0.3 to 2.3 TeV depending on the new physics effect under consideration. (C) 2004 Published by Elsevier B.V.

Abstract: We search, in the context of extra-dimension scenarios, for the possible existence of brane fluctuations, called branons. Events with a single photon or a single Z-boson and missing energy and momentum collected with the L3 detector in e+e− collisions at centre-of-mass energies √2 = 189–209 GeV are analysed. No excess over the Standard Model expectations is found and a lower limit at 95% confidence level of 103 GeV is derived for the mass of branons, for a scenario with small brane tensions. Alternatively, under the assumption of a light branon, brane tensions below 180 GeV are excluded., Facultad de Ciencias Exactas
