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: The performance of a readout system for the Synchrotron Radiation Detector (SRD) is studied. The detector is proposed as part of the Alpha Magnetic Spectrometer experiment, an experiment to fly on the International Space Station (ISS) beginning of 2005. The SRD is designed to detect the synchrotron radiation from electrons and positrons (TeV energy range) produced in the earth's magnetic field. For the planned array of scintillators and photomultipliers a readout system is chosen, which is compact, space qualified and has a low-power consumption. The low-power chip APV, originally designed for the CMS experiment at LHC (CERN), is foreseen for the readout. To overcome the diffuse background from photons and charged particles the SRD readout must have a time resolution better than 10 ns. The intrinsic time resolution (sigma from Gauss fit) of the APV25-S0 was found to be 0.46±0.01 and 0.68±0.02 ns for the APVM, whereas the time resolution of the photomultiplier-APV readout system was measured to be 2.73±0.10 ns for the APV25-S0 and 2.90±0.21 ns for the APVM. The investigated timing capabilities of the photomultiplier-APV readout system show that the APV chip is suitable for the SRD readout.

Abstract: The vertex drift chamber of the L3 Experiment at LEP, based on the time expansion principle, was in operation from the start-up of LEP in 1989 until the shutdown of LEP in 2000. The gas mixture used was 80% CO2 and 20% i-C4H10 at a pressure of . We present the design of the chamber, the infrastructure and the performance during the 11 years of operation. The total radiation received on the anode wires was ~10-4 C/cm. No degradation of the anode pulse amplitude, wire efficiencies and resolution was observed for the whole running period.

Abstract: We present a study of the global event shape variables thrust and heavy jet mass, of energy-energy correlations and of jet multiplicities based on 250 000 hadronic Z 0 decays. The data are compared to new QCD calculations including resummation of leading and next-to-leading logarithms to all orders. We determine the strong coupling constant α s (91.2 GeV) = 0.125±0.003 (exp) ± 0.008 (theor). The first error is the experimental uncertainty. The second error is due to hadronization uncertainties and approximations in the calculations of the higher order corrections.

Abstract: A Synchrotron Radiation Detector measures synchrotron radiation emitted by high energetic particles in the earth magnetic field. This allows to identify cosmic ray electrons and positrons with energies in the TeV region. One possibility for such a detector outside the atmosphere uses YAP crystals to measure synchrotron photons with energies in the keV range. As such a detector can not distinguish between photons and electrons, the main problems are the diffuse cosmic ray gamma background and low energetic electrons in the vicinity of the earth. While the intensity of the diffuse gamma rays is known quite well, there exists limited knowledge about keV-electrons in low earth orbits. To measure these electrons a Prototype Synchrotron Radiation Detector (PSRD) was flown with Space Shuttle mission STS-108 (Dec.2001) and preliminary analysis of the data show very favorable results.

Abstract: The Prototype Synchrotron Radiation Detector (PSRD) is a small-scale experiment designed to measure the rate of low-energy charged particles and photons in near the Earth's orbit. It is a precursor to the Synchrotron Radiation Detector (SRD), a proposed addition to the upgraded version of the Alpha Magnetic Spectrometer (AMS-02). The SRD will use the Earth's magnetic field to identify the charge sign of electrons and positrons with energies above 1 TeV by detecting the synchrotron radiation they emit in this field. The differential energy spectrum of these particles is astrophysically interesting and not well covered by the remaining components of AMS-02. Precise measurements of this spectrum offer the possibility to gain information on the acceleration mechanism and characteristics of all cosmic rays in our galactic neighbourhood. The SRD will discriminate against protons as they radiate only weakly. Both the number and energy of the synchrotron photons that the SRD needs to detect are small. The identification is complicated by the presence of a large particle and photon background. Existing measurements of these backgrounds are insufficient for the construction of the large-scale SRD, so a measurement in space was indispensable. The PSRD was designed to fly as a Space Shuttle secondary payload, within the Shuttle Small Payloads Project. The flight on board the Space Shuttle Endeavour took place from 5 to 17 December 2001. The scientific goal, hardware and the flight of the PSRD are described in this report.

Abstract: We have measured the partial widths of the Z 0 into lepton pairs, and the forward-backward charge asymmetry for the process e + e − → μ + μ − using the L3 detector at LEP. We obtain an average Γ ll of 83.0±2.1±1.1 MeV.From this result and the asymmetry measurement, we extract the values of the vector and axial vector couplings of the Z 0 to leptons: g rmv =−0.066 −0.027 +0.046 and g rmA = −0.495 −0.007 +0.007 .

Abstract: A measurement of the cosmic ray positron fraction e+ / (e+ + e-) in the energy range of 1-30 GeV is presented. The measurement is based on data taken by the AMS-01 experiment during its 10 day Space Shuttle flight in June 1998. A proton background suppression on the order of 106 is reached by identifying converted bremsstrahlung photons emitted from positrons., Physics Letters B, 646 (4), ISSN:0370-2693, ISSN:0031-9163, ISSN:1873-2445

Abstract: We describe the construction, test and installation procedures, and the experience gained with the operation of a small but complete system of high-rate Micro-Strip Gas Chambers, made on thin borosilicate glass with a diamond-like coating with chromium or gold strips. A set of detectors, fully equipped with read-out electronics and each with an active area of 100 × 100 mm 2 , was exposed during six months to a high-intensity muon beam at CERN with a peak intensity of ∼ 10 4 mm −2 s −1 . Continuous monitoring of the performance of the chambers during the beam runs allowed the evaluation of detection efficiency and the monitoring of accidental rates, as well as the study of ambient induced variations and aging in realistic beam conditions. No significant difference has been found in the operation of under-and over-coated plates. Efficiencies could reach ∼ 98% in best operating conditions, although local lower values were often observed due to missing channels (open strips, broken bonds and dead electronic channels). The long-term operation of the chambers has been more difficult than expected, with the appearance of break-downs and loss of efficiency in some detectors, possibly induced by the presence of small gas leaks, to water permeation or to residual reactivity of the quencher gas (dimethylether).

Abstract: We have studied the process e+e− → nγ (n ≥ 2) at an average center-of-mass energy of 133 GeV using the L3 detector at LEP. For an integrated luminosity of 4.95 pb−1 we find one γγγγ(γ) final state with only hard photons. The rates of both γγγ and γγ events are consistent with QED expectations. The cross section of the reaction e+e− → γγ(γ) in the polar range 16° < θγ < 164° is measured to be 22.6 ± 2.2 pb. Decays into photons of narrow scalar resonances with masses between 90 and 130 GeV are not observed. The observation of the event with four energetic photons is consistent with QED although the kinematic configuration of the photons is atypical.

Abstract: The inclusive semileptonic branching ratios b→eνX,μ νX,τ νX andνX have been measured at LEP with the L3 detector. The analysis is based on 2-jet hadronic Z decays obtained in the data collected between 1991 and 1992. Three separate event samples are analysed, containing electrons, muons and large missing energy (neutrinos), respectively. From the electron sample, we measure Br(b→eνX)=(10.89±0.20±0.51)% and, from the muon sample, Br(b→μ νX)=(10.82±0.15±0.59)%, where the first error is statistical and the second is systematic. From the missing energy sample, we measure Br(b→νX)=(23.08±0.77±1.24)%, assuming the relative semileptonic decay rates e:μ:τ=1:1:(0.25±0.05), according to theoretical expectations. From a combined analysis of all three samples and constraining the relative semileptonic rates, we measure Br(b→eνX)=Br(b→μ νX)=(10.68±0.11±0.46)%. Alternatively, we can remove the constraint on the relative semileptonic rates and measure Br(b→τ νX)=(1.7±0.5±1.1)%.

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 present a study of the structure of hadronic events recorded by the L3 detector at center-of-mass energies of 130 and 136 GeV. The data sample corresponds to an integrated luminosity of 5 pb-1 collected during the high energy run of 1995. The shapes of the event shape distributions and the energy dependence of their mean values are well reproduced by QCD models. From a comparison of the data with resummed O(alpha_s^2) QCD calculations, we determine the strong coupling constant to be alpha_s(133 GeV) = 0.107 +/- 0.005(exp) +/- 0.006(theor).

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: 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: We have studied the four-fermion processes ee → eeee, eeμμ, eeττ, μμμμ, μμττ, eeqq and μμqq with the L3 detector at LEP. For an integrated luminosity of 36 pb-, corresponding to 960 000 hadronic Z decays, we find a total of 67 candidate events. The rate and kinematical distributions are found to be consistent with first order Monte Carlo calculations based on the Standard Model. No significant structure is seen in the dilepton invariant or recoil mass spectra. © 1994.

Abstract: The variety of isotopes in cosmic rays allows us to study different aspects of the processes that cosmic rays undergo between the time they are produced and the time of their arrival in the heliosphere. In this paper, we present measurements of the isotopic ratios [superscript 2]H/[superscript 4]He, [superscript 3]He/[superscript 4]He, [superscript 6]Li/[superscript 7]Li, [superscript 7]Be/([superscript 9]Be+[superscript 10]Be), and [superscript 10]B/[superscript 11]B in the range 0.2-1.4 GeV of kinetic energy per nucleon. The measurements are based on the data collected by the Alpha Magnetic Spectrometer, AMS-01, during the STS-91 flight in 1998 June., United States.

Abstract: The effective electroweak mixing angle sin2θw is measured from the production and decay of the Z boson in e+e- interactions. The data sample corresponds to an integrated luminosity of 18 pb-l with about 420 000 hadronic and 40 000 leptonic Z decays. The mixing angle sin 22θw is determined from several independent measurements: the leptonic and hadronic cross sections, the forward-backward asymmetries of charged leptons and b-quarks, and the z-polarization. The results are found to be in good agreement with each other. The value of sin 22θw from a fit to the asymmetries in a model independent method is 0.2321-4-0.0021 and from a global fit to the data in the Standard Model framework is 0.2328±0.0013., Facultad de Ciencias Exactas

Abstract: The L3 central tracking detector has been in operation since the start-up of LEP (Large Electron Positron collider) in 1989. This detector consists of a Time Expansion Chamber (TEC), a layer of Plastic Scintillating Fibers and a Z-chamber. The TEC gives a high spatial resolution and an excellent multi-track reconstruction capability. The fibers are designed to calibrate the drift velocity with high precision. The Z-Chamber provides TEC with accurate information about the z-coordinates of the tracks. A description of the design and the infrastructure of these three detectors, including the readout and data acquisition system, is given. The performance of the detectors during the 1990 and 1991 LEP running periods is presented.

Abstract: We search for neutral heavy leptons that are isosinglets under the standard SU(2)L gauge group. Such neutral heavy leptons are expected in many extensions of the standard model. Three types of heavy leptons Ne, N(mu), N(tau) associated with the three neutrino types nu(e), nu(mu), nu(tau) have been directly searched for and no evidence for a signal has been found. We set the limit Br(Z0 --> nu(l)N(l)) < 3 x 10(-5) at the 95% CL for the mass range from 3 GeV up to m(Z).

Abstract: We have measured the forward-backward asymmetry in e + e − → b b and e + e − → c c processes using hadronic events containing muons or electrons. The data sample corresponds to 4100000 hadronic decays of the Z0. From a fit to the single lepton and dilepton p and pT spectra, we determine A b b =0.086±0.015±0.007 and A c c =0.083±0.038±0.027 at the effective center-of-mass energy √s=91.24 GeV. These measurements yield a value of the electroweak mixing angle sin 2 θ w =0.2336±0.0029 .

Abstract: We have measured the total and differential cross sections of the reaction e+e− → γγ(γ) at center-of-mass energies around 91 GeV, with an integrated luminosity of 14.2 pb−1. The results are in good agreement with QED predictions. We set lower limits, at 95% confidence level, on the QED cutoff parameters of Λ+ > 139 GeV, Λ− > 108 GeV and on the mass of an excited electron of m e∗ > 127 GeV . We searched for Z0 rare decays with photonic signitures in the final state. Upper limits, at 95% confidence level, for branching ratio of Z0 decaying into π0γ/γγ, νγ and γγγ are 1.2 × 10−4, 1.8 × 10−4, 3.3 × 10−5 respectively.

Abstract: The L3 vertex detector is comprised of the time expansion chamber (TEC), the Z -chamber and a layer of plastic scintillating fibers. The TEC has shown a high spatial resolution and an excellent multi-track reconstruction capability at LEP luminosity. The Z -chamber provides information about the z -coordinates of the tracks and the fibers are used for calibrating the drift velocity with a high precision. A description of the L3 vertex detector, its readout and data acquisition and its performance during the 1990 LEP running period is presented in this paper.

Abstract: We have measured the forward-backward asymmetry in Z 0 → b b decays using hadronic events containing muons and electrons. The data sample corresponds to 118 200 hadronic events at √s≈Mz. From a fit to the single and dilepton p and P⊥ spectra, we determine A b b =0.130 −0.042 +0.044 including the correction for B 0 − B 0 mixing.

Abstract: Whatever the field, major change implies as much as deep transformation of thinking i.e to put in network new skills in particular, those made available by the availability of new technologies. In this context, only one individual cannot join together all necessary skills. It becomes clear that the goal of space valorization cannot be considered without relational investment between the partners and their accumulated background. The local empowerment concerns a collective phenomenon of acquisition and development of skills rests on an learning way appropriate to the potential of the territory to form or promote. The local mediation sets for objective the creation of relations between pre-existent skills and their transfer between the actors, individuals or groups, private or public. But the capacity of the territory to solve these problems will depend closely on the richness of the network and co-operations which it shelters or it will suggest.

Abstract: The L3 experiment is one of the six large detectors designed for the new generation of electron-positron accelerators. It is the only detector that concentrates its efforts on limited goals of measuring electrons, muons and photons. By not attempting to identify hadrons, L3 has been able to provide an order of magnitude better resolution for electrons, muons and photons. Vertices and hadron jets are also studied. The construction of L3 has involved much state of the art technology in new principles of vertex detection and in new crystals for large scale electromagnetic shower detection and ultraprecise muon detection. This paper presents a summary of the construction of L3.

Abstract: We have searched for charged and neutral leptons. We exclude stable Dirac neutrinos below 42.8 GeV and stable Majorana neutrinos below 34.8 GeV. From a search for unstable neutrinos we exclude masses below 46.4 GeV (Dirac) and below 45.1 GeV (Majorana). We exclude all masses of sequential charged and neutral leptons, except if both masses are larger than 42.8 GeV (for stable Dirac neutrinos). All mass limits correspond to 95% CL.

Abstract: Inside the CMS detector 1 charged particles are measured precisely with layers of low-occupancy silicon detectors and Micro Strip Gas Chambers (MSGCs) with pitches of 50 and 200 μm, respectively. Low occupancy is achieved by a high granularity of 3×106 channels for silicon detectors and 11×106 for MSGCs. For the CMS forward tracker we tested a closed MSGC module with wedge-shaped strip patterns on 300 μm DESAG263 2 glass substrates produced by OPTIMASK. Using a 100 GeV μ-beam at CERN we investigated the behaviour of this MSGC module foreseen for four wedge-shaped substrates, 512 strips each.

Abstract: Inelastic nuclear collisions of hadrons incident on silicon sensors can generate secondary highly ionising particles (HIPs) and deposit as much energy within the sensor bulk as several hundred minimum ionising particles. The large signals generated by these 'HIP events' can momentarily saturate the APV25 front-end readout chip for the silicon strip tracker (SST) sub-detector of the compact muon solenoid (CMS) experiment, resulting in deadtime in the detector readout system. This paper presents studies of this phenomenon through simulation, laboratory measurements and dedicated beam tests. A proposed change to a front-end component to reduce the APV25 sensitivity to HIP events is also examined. The results are used to infer the expected effect on the performance of the CMS SST at the future large hadron collider. The induced inefficiencies are at the percent level and will have a negligible effect on the physics performance of the SST. (c) 2005 Elsevier B.V. All rights reserved.

Abstract: Using a sample of e+e− annihilation events collected at the Z resonance corresponding to an integrated luminosity of 11.2 pb−1, we have searched for γX final states where X represents stable, weakly interacting particles and the energy of the photon is greater than 1 2 E beam . No events were found. The results have been interpreted within a composite Z model and a supergravity model with a light gravitino.

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: We have measured the properties of Z0 → b b decays using a sample of 944 inclusive muon events, corresponding to 18 000 hadron events obtained with the L3 detector at LEP. We measured the partial decay width of the Z0 into b b , Γ b b =353±48 MeV , and we determined the vector coupling of the Z0 to the b quark; grmv2(b)=0.095±0.047. We measured the forward-backward charge asymmetry in e+e− → b b events at √s≈Mv, and obtained A b b =13.3±9.9% .

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: 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: General aspects of the H1 detector at the electron-proton storage ring HERA as well as technical descriptions of the magnet, luminosity system, trigger, slow-control, data acquisition and off-line data handling are given. The three major components of the detector, the tracking, calorimeter and muon detectors, will be described in a forthcoming article. The present paper describes the detector that was used from 1992 to the end of 1994. After this a major upgrade of some components was undertaken. Some performance figures from luminosity runs at HERA during 1993 and 1994 are given.

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: A cerium fluoride matrix composed of nine longitudinally segmented towers, approximately 25 X 0 long, has been tested in electron, muon and pion beams of momenta ranging from 10 to 150 GeV/ c . The results are discussed in terms of light yield, electronic noise, energy and position resolution. In spite of serious imperfections in geometry and quality of some of the crystals, an electron energy resolution of ∼0.5% has been obtained with a silicon photodiode readout, for energies above 50 GeV. The performance of cerium fluoride in a beam, its high density, high light yield and fast response, radiation resistance and ruggedness make it a very good candidate for high-resolution calorimetry at future colliders. The best conditions for production of large high-quality crystals are being studied in several firms over the world. Many CeF 3 crystals, 2 × 2 cm 2 or 3 × 3 cm 2 in cross section and up to 28 cm long, were received in 1994 from four companies, some of them with excellent light yield and radiation hardness.

Abstract: We have studied the process e(+)e(-)-->n gamma (n greater than or equal to 2) at an average center-of-mass energy of 133 GeV using the L3 detector at LEP. For an integrated luminosity of 4.95 pb(-1) we find one gamma gamma gamma gamma(gamma) final state with only hard photons. The rates of both gamma gamma gamma and gamma gamma events are consistent with QED expectations. The cross section of the reaction e(+)e(-) -->gamma gamma(gamma) in the polar range 16 degrees
