Abstract: Results are presented from a study of the structure of high energy hadronic events recorded by the L3 detector at sqrt(s)>192 GeV. The distributions of several event shape variables are compared to resummed O(alphaS^2) QCD calculations. We determine the strong coupling constant at three average centre-of-mass energies: 194.4, 200.2 and 206.2 GeV. These measurements, combined with previous L3 measurements at lower energies demonstrate the running of alphaS as expected in QCD and yield alphaS(mZ) = 0.1227 +- 0.0012 +- 0.0058, where the first uncertainty is experimental and the second is theoretical.

Abstract: The production of c and b quarks in gamma-gamma collisions is studied with the L3 detector at LEP with 410 pb^-1 of data, collected at centre-of-mass energies from 189 GeV to 202 GeV. Hadronic final states containing c and b quarks are identified by detecting electrons or muons from their semileptonic decays. The cross sections sigma(e+e- -> e+e- c c~ X) and sigma(e+e- -> e+e- b b~ X) are measured and compared to next-to-leading order perturbative QCD calculations. The cross section of b production is measured in gamma-gamma collisions for the first time. It is in excess of the QCD prediction by a factor of three. The production of c and b quarks γγ collisions is studied with the L3 detector at LEP with 410 pb −1 of data, collected at centre-of-mass energies from 189 GeV to 202 GeV. Hadronic final states containing c and b quarks are identified by detecting electrons or muons from their semileptonic decays. The cross sections σ( e + e − → e + e − c c ̄ X ) and σ( e + e − → e + e − b b ̄ X ) are measured and compared to next-to-leading order perturbative QCD calculations. The cross section of b production is measured in γγ collisions for the first time. It is in excess of the QCD prediction by a factor of three.

Abstract: Matière Nucléaire; The $e^+ e^- \rightarrow e^+ e^- K^{0}_{s} K^{\pm} pi^{\mp}$ and $e^+ e^- \rightarrow e^+ e^- \eta \pi^{+} \pi^{-}$ 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 $K^{0}_{s} K^{\pm} \pi^{\mp}$ final state shows an enhancement around 1470 MeV, which is identified with the pseudoscalar meson $\eta(1440)$. This state is observed in $\gamma \gamma$ collisions for the first time and its two-photon width is measured to be $\Gamma_{\gamma\gamma}(\eta(1440)) x BR(\eta(1440) \rightarrow K\bar{K}\pi = 212 \pm 50 (stat) \pm 23 (sys)$ eV. Clear evidence is also obtained for the formation of the axial vector mesons $f_1$(1420) and $f_1$(1285). In the $\eta \pi^{+} \pi^{-}$ channel the $f_1$ (1285)} is observed, and upper limits for the formation of $\eta(1440)$ and $\eta(1295)$ are obtained.

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

Abstract: The process e^+e^- -> Z gamma gamma -> q q~ gamma gamma$ 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 < a_0/\Lambda^2 < 0.005 GeV-2 and -0.007 GeV-2 < a_c/\Lambda^2 < 0.011 GeV-2, at 95% confidence level. 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.

Abstract: The cross section for the production of Z boson pairs is measured using the data collected by the L3 detector at LEP in 1999 in $\rm e^+e^-$ collisions at centre--of--mass energies ranging from 192 GeV up to 202 GeV. Events in all the visible final states are selected, measuring the cross section of this process. The special case of final states containing b quarks is also investigated. All results are in agreement with the Standard Model predictions.

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

Abstract: Excited leptons are searched for using the L3 detector at LEP. The data collected at centre-of-mass energies in the range from 192 up to 202 GeV correspond to a total luminosity of 233 $\rm pb^{-1}$. No evidence of either pair production of excited leptons, nor of single production is found. From the searches for pair produced excited leptons, lower mass limits close to the kinematic limit are set. From the searches for singly produced excited leptons, upper limits on their couplings are derived in the mass range up to 200 GeV. Excited leptons are searched for using the L3 detector at LEP.

Abstract: The $e^+ e^- \rightarrow e^+ e^- K^{0}_{s} K^{\pm} pi^{\mp}$ and $e^+ e^- \rightarrow e^+ e^- \eta \pi^{+} \pi^{-}$ 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 $K^{0}_{s} K^{\pm} \pi^{\mp}$ final state shows an enhancement around 1470 MeV, which is identified with the pseudoscalar meson $\eta(1440)$. This state is observed in $\gamma \gamma$ collisions for the first time and its two-photon width is measured to be $\Gamma_{\gamma\gamma}(\eta(1440)) x BR(\eta(1440) \rightarrow K\bar{K}\pi = 212 \pm 50 (stat) \pm 23 (sys)$ eV. Clear evidence is also obtained for the formation of the axial vector mesons $f_1$(1420) and $f_1$(1285). In the $\eta \pi^{+} \pi^{-}$ channel the $f_1$ (1285)} is observed, and upper limits for the formation of $\eta(1440)$ and $\eta(1295)$ are obtained. The e + e − →e + e − K S 0 K ± 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 K 0 S K ± π ∓ final state shows an enhancement around 1470 MeV, which is identified with the pseudoscalar meson η (1440). This state is observed in γγ collisions for the first time and its two-photon width is measured to be Γ γγ (η(1440))× BR (η(1440)→ K K ̄ π)=212±50 ( stat. )±23 (sys.) eV. Clear evidence is also obtained for the formation of the axial vector mesons f 1 (1420) and f 1 (1285). In the ηπ + π − channel the f 1 (1285) is observed, and upper limits for the formation of η (1440) and η (1295) are obtained. The e+e- -> e+e- Ks K+- pi-+ e+e- -> e+e- eta pi+ pi- and 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 Ks K+- pi-+ final state shows an enhancement around 1470MeV, which is identified with the pseudoscalar meson eta(1440). This state is observed in gamma gamma collisions for the first time and its two-photon width is measured to be Gamma_gamma gamma(eta(1440))x BR(eta(1440)->KK pi)= 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 eta pi+ pi- channel the f1(1285) is observed, and upper limits for the formation of eta(1440) and eta(1295) are obtained.

Abstract: The process e$^+$e$^-\rightarrow {\rm W}^+{\rm W}^-\gamma$ is analysed using the data collected with the L3 detector at LEP at a centre-of-mass energy of $188.6$ GeV, corresponding to an integrated luminosity of 176.8 pb$^{-1}$. Based on a sample of 42 selected ${\rm W}^+{\rm W}^-$ candidates containing an isolated hard photon, the ${\rm W}^+{\rm W}^-\gamma$ cross section, defined within phase-space cuts, is measured to be: $\sigma_{{\rm WW}\gamma} = 290 \pm 80 \pm 16$ fb, consistent with the Standard Model expectation. Including the process e$^+$e$^-\rightarrow \nu\bar\nu \g\g$, limits are derived on anomalous contributions to the Standard Model quartic vertices ${\rm W}^+{\rm W}^-\gamma\gamma$ and ${\rm W}^+{\rm W}^-{\rm Z}\gamma$ at 95\%~CL: \begin{eqnarray*} -0.043 \GeV^{-2} & < & a_0/\Lambda^2 ~ < ~ 0.043 \GeV^{-2} \\ \phantom{0}-0.08 \GeV^{-2} & < & a_c/\Lambda^2 ~ < ~ 0.13\phantom{0} \GeV^{-2} \\ \phantom{0}-0.41 \GeV^{-2} & < & a_n/\Lambda^2 ~ < ~ 0.37\phantom{0} \GeV^{-2}. \end{eqnarray*} The process e + e − →W + W − γ is analysed using the data collected with the L3 detector at LEP at a centre-of-mass energy of 188.6 GeV , corresponding to an integrated luminosity of 176.8 pb −1 .

Abstract: We investigate \BE\ correlations (BEC) in W-pair production at $\sqrt{s}\simeq189 \GeV$ using the L3 detector at LEP. We observe BEC between particles from a single W~decay in good agreement with those from a light-quark Z~decay sample. We investigate their possible existence between particles coming from different W's. No evidence for such \interW\ BEC is found.

Abstract: In a search for the Standard Model Higgs boson, carried out on 212.5 pb-1 of data collected by the L3 detector at the highest LEP centre-of-mass energies, including 116.5 pb-1 above root(s) = 206GeV, an excess of candidates for the process e+e- -> Z* -> HZ is found for Higgs masses near 114.5GeV. We present an analysis of our data and the characteristics of our strongest candidates.

Abstract: We investigate Bose-Einstein correlations (BEC) in W-pair production at $\sqrt{s}\simeq 189 \GeV$ using the L3 detector at LEP. We observe BEC between particles from a single W decay in good agreement with those from a light-quark Z~decay sample. We investigate their possible existence between particles coming from different W's. No evidence for such \interW\ BEC is found.

Abstract: The measurements of $R_{b} = \sigma(e^+e^-} \to b\overline{b})/\sigma( e^+e^-} \to{m q\overline{q})$ and of the b quarkforward--backward charge asymmetry,$A_fb}^{b}$, at centre--of--mass energies above the Z pole are described. The measurement of $R_{b}$ is performed at $\sqrt{s}$ between 130 and 189 GeV using a b--tagging method thatexploits the relatively large decay length ofb--hadrons. The measurement of $A_{fb}^{b}$ is performedusing the large statistics event sample collected at $\sqrt{s}$=189 GeV with a lepton--tag analysis based on the selection of prompt muons and electrons. The results at $\sqrt{s}$=189 GeV are: $R_{b} = 0.163 pm 0.013 (stat.) pm 0.005 (syst.)$, $A_{fb}^{b} = 0.61 pm 0.18 (stat.) pm 0.09 (syst.).$ The measurements of R b =σ( e + e − → b b ̄ )/σ( e + e − → q q ̄ ) and of the b quark forward–backward charge asymmetry, A fb b , at centre-of-mass energies above the Z pole are described. The measurement of R b 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 A fb b is performed using the large statistics event sample collected at s =189 GeV with a lepton-tag analysis based on the selection of prompt muons and electrons. The results at s =189 GeV are R b =0.163±0.013 (stat.) ±0.005 (syst.) , A fb b =0.61±0.18 (stat.) ±0.09 (syst.) . The measurements of Rb = sigma(e+e- -> bb~)/sigma(e+e- -> qq~) and of the b quark forward-backward charge asymmetry, A^b_fb, at centre-of-mass energies above the Z pole are described. The measurement of Rb is performed at \root{s} between 130 and 189 GeV using a b-tagging method that exploits the relatively large decay length of b-hadrons. The measurement of A^b_fb is performed using the large statistics event sample collected at \root{s}=189 GeV with a lepton-tag analysis based on the selection of prompt muons and electrons. The results at \root{s}=189 GeV are: Rb = 0.163 +/- 0.013 (stat.) +/- 0.005 (syst.), A^b_fb = 0.61 +/- 0.18 (stat.) +/- 0.09 (syst.).

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

Abstract: Single W boson production in electron-positron collisions is studied with the L3 detector at LEP. The data sample collected at a centre-of-mass energy of $\sqrt{s} = 188.7 \mathrm{\ Ge\kern -0.1em V}{}$ corresponds to an integrated luminosity of $176.4\,\mbox{pb$^{-1}$}$. Events with a single energetic lepton or two acoplanar hadronic jets are selected. Within phase-space cuts, the total cross-section is measured to be $0.53 \pm 0.12 \pm 0.03 \; \rm{pb}$, consistent with the Standard Model expectation. Including our single W boson results obtained at lower $\sqrt{s}$, the WW$\gamma$ gauge couplings $\kappa_\gamma$ and $\lambda_\gamma$ are determined to be \mbox{$\kappa_\gamma = 0.93 \pm 0.16 \pm 0.09$} and \mbox{$\lambda_\gamma = -0.31^{+0.68}_{-0.19} \pm 0.13$}. Single W boson production in electron-positron collisions is studied with the L3 detector at LEP. The data sample collected at a centre-of-mass energy of s =188.7 GeV corresponds to an integrated luminosity of 176.4 pb −1 . Events with a single energetic lepton or two acoplanar hadronic jets are selected. Within phase-space cuts, the total cross-section is measured to be 0.53±0.12±0.03 pb , consistent with the Standard Model expectation. Including our single W boson results obtained at lower s , the WW γ gauge couplings κ γ and λ γ are determined to be κ γ =0.93±0.16±0.09 and λ γ =−0.31 +0.68 −0.19 ±0.13.

Abstract: Context. Primary cosmic rays experience multiple deflections in the non-uniform galactic and heliospheric magnetic fields which may generate anisotropies. Aims. A study of anisotropies in the energy range between 100 and 500 GeV is performed. This energy range is not yet well explored. Methods. The L3 detector at the CERN electron-positron collider, LEP, is used for a study of the angular distribution of atmospheric muons with energies above 20 GeV. This distribution is used to investigate the isotropy of the time-dependent intensity of the primary cosmic-ray flux with a Fourier analysis. Results. A small deviation from isotropy at energies around 200 GeV is observed for the second harmonics at the solar frequency. No sidereal anisotropy is found at a level above 10(-4). The measurements were performed in the years 1999 and 2000.

Abstract: The (KSK +/-)-K-0 pi(-/+) final state in two-photon collisions is studied with the L3 detector at LEP at e(+)e(-) centre- of- mass energies from 183 to 209 GeV with an integrated luminosity of 664.6 pb(-1). The eta (1475) and f(1)(1420) mesons are observed and their contribution is separated by measuring the formation rates as a function of the photon virtuality Q(2). The eta(1475) is found to be dominant for Q(2) <= 0.01 GeV2 and its two- photon width is measured to be 0.23 +/- 0.05 (stat.) +/- 0.05 (sys.) keV. At higher Q(2), the f(1)(1420) is formed and decays to K*(892) K. The coupling and form factor parameters of this state are measured to be Gamma(gamma gamma) = 3.2 +/- 0.6 (stat.) +/- 0.7 ( sys.) keV and Lambda(1) = 926 +/- 72 (stat.) +/- 32 (sys.) MeV, respectively.

Abstract: The mass and the total decay width of the W boson are measured with the L3 detector at the LEP e(+)e(-) collider using W-boson pairs produced in 0.7 fb(-1) of data collected at centre-of-mass energies between 161 and 209 GeV. Combining semi-leptonic and fully-hadronic final states, the mass and the width of the W boson are determined to be m(W) = 80.270 +/- 0.046 +/- 0.031 GeV and Gamma(W) = 2.18 +/- 0.11 +/- 0.09 GeV , where the first uncertainty is statistical and the second systematic.

Abstract: Hadron production and lepton-pair production in e(+)e(-) collisions are studied with data collected with the L3 detector at LEP at centre-of-mass energies root s = 192-208 GeV. Using a total integrated luminosity of 453 pb(-1), 36057 hadronic events and 12863 lepton-pair events are selected. The cross sections for hadron production and lepton-pair production are measured for the full sample and for events where no high-energy initial-state-radiation photon is emitted prior to the collisions. Lepton-pair events are further investigated and forward-backward asymmetries are measured. Finally, the differential cross sections for electron-positron pair-production is determined as a function of the scattering angle. An overall good agreement is found with Standard Model predictions.

Abstract: The reactions gamma gamma -> pi(+)pi(-)pi(+)pi(-) and gamma gamma -> pi(+)pi(0)pi(-)pi(0) 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 rho(0)rho(0) and p(+)p(-) 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.

Abstract: The L3+C muon detector at the CERN electron-positron collider, LEP, is used for the detection of very-high-energy cosmic gamma-ray sources through the observation of muons of energies above 20, 30, 50 and 100 GeV. Daily or monthly excesses in the rate of single-muon events pointing to some particular direction in the sky are searched for. The periods from mid July to November 1999, and April to November 2000 are considered. Special attention is also given to a selection of known gamma-ray sources. No statistically significant excess is observed for any direction or any particular source. (c) 2006 Elsevier B.V. All rights reserved.

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.

Abstract: Compton scattering of quasi-real virtual photons, gamma e(+/-) -> gamma e(+/-), is studied with 0.6 fb(-1) of data collected by the L3 detector at the LEP e(+)e(-) collider at centre-of-mass energies root s = 189-209 GeV. About 4500 events produced by the interaction of virtual photons emitted by e(+/-) of one beam with e(-/+) of the opposite beam are collected for effective centre-of-mass energies of the photon-electron and photon-positron systems in the range from root s' = 35 GeV up to root s' = 175 GeV, the highest energy at which Compton scattering was ever probed. The cross sections of the gamma e(+/-) -> gamma e(+/-) process as a function of root s' and of the rest-frame scattering angle are measured, combined with previous U measurements down to root s' similar or equal to 20 GeV, and found to agree with the QED expectations.

Abstract: Data collected at LEP at centre-of-mass energies root s = 189-209 GeVare used to study correlations of the spin of W bosons using e(+)e(-) -> W+W- -> lvq (q) over bar events. Spin correlations are favoured by data, and found to agree with the Standard Model predictions. In addition, correlations between the W-boson decay planes are studied in e(+)e(-) -> W+W- -> lvq (q) over bar and e(+)e(-) -> W+W- -> q (q) over barq (q) over bar events. Decay-plane correlations are measured to be consistent with the Standard Model predictions.

Abstract: The e(+)e(-) -> e(+)e(-)hadrons reaction, where one of the two electrons is detected in a low polar-angle calorimeter, is analysed in order to measure the hadronic photon structure function F-2(gamma) The full high-energy and high-luminosity data set, collected with the U detector at centre-of-mass energies 189 GeV <= root s <= 209 GeV, corresponding to an integrated luminosity of 608 pbis used. The Q(2) range 11 GeV2 <= Q(2) <= 34 GeV2 and the x range 0.006 <= x <= 0.556 are considered. The data are compared with recent parton density functions. (c) 2005 Published by Elsevier B.V.

Abstract: The evolution of the electromagnetic coupling, alpha, in the momentum-transfer range 1800 GeV2 < -Q(2) < 21600 GeV2 is studied with about 40 000 Bhabha-scattering events collected with the L3 detector at LEP at centre-of-mass energies root s = 189-209 GeV. The running of a is parametrised as: alpha(Q(2)) = (1-C Delta alpha(Q2))/(alpha 0) where alpha(0) = alpha(Q(2) = 0) is the fine-structure constant and C = 1 corresponds to the evolution expected in QED. A fit to the differential cross section of the e(+)e(-) -> e(+)e(-) process for scattering angles in the range vertical bar cos theta vertical bar < 0.9 excludes the hypothesis of a constant value of alpha, C = 0, and validates the QED prediction with the result: C = 1.05 +/- 0.07 +/- 0.14, where the first uncertainty is statistical and the second systematic.

Abstract: The cross section for open-beauty production in photon-photon collisions is measured using the whole high-energy and high-luminosity data sample collected by the L3 detector at LEP. This corresponds to 627 pb(-1) of integrated luminosity for electron-positron centre-of-mass energies from 189 to 209 GeV Events containing b quarks are identified through their semi-leptonic decay into electrons or muons. The e(+)e(-) -> e(+)e(-)bbX cross section is measured within our fiducial volume and then extrapolated to the full phase space. These results are found to be in significant excess with respect to Monte Carlo predictions and next-to-leading order QCD calculations. (c) 2005 Published by Elsevier B.V.

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 U 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. (C) 2005 Published by Elsevier B.V.

Abstract: The double-radiative process e(+)e(-) &RARR; Zγγ &RARR; q $(q) over bar $ γγ 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. © 2005 Published by Elsevier B.V.

Abstract: The cross section for open-beauty production in photon photon collisions is measured using the whole high-energy and high-luminosity data sample collected by the L3 detector at LEP. This corresponds to 627 pb-1 of integrated luminosity for electron positron centre-of-mass energies from 189 to 209 GeV. Events containing b quarks are identified through their semi-leptonic decay into electrons or muons. The e+e-→e+e-bb ̄X cross section is measured within our fiducial volume and then extrapolated to the full phase space. These results are found to be in significant excess with respect to Monte Carlo predictions and next-to-leading order QCD calculations.
