Production of single W bosons in e<sup>+</sup>e<sup>-</sup> interactions at 130 ≤ √s ≤ 183 GeV and limits on anomalous WWγ couplings
, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, Vol: 436, Pages: 417-427, ISSN: 0370-2693We report on a study of single W boson production in a data sample collected by the L3 detector at centre-of-mass energies from 130 to 183 GeV. The signal consists of large missing energy final states with a single energetic lepton or two hadronic jets. The measured cross sections at five different centre-of-mass energies are consistent with the Standard Model expectations. The following limits on the anomalous WWγ gauge couplings are derived at 95% CL: -0.46 < Δκγ < 0.57 and -0.86 < λγ < 0.75. © 1998 Elsevier Science B.V. All rights reserved.

Measurement of the inclusive charmless semileptonic branching fraction of beauty hadrons and a determination of
, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, Vol: 436, Pages: 174-186, ISSN: 0370-2693A measurement of the inclusive charmless semileptonic branching fraction of beauty hadrons, b → Xuℓν, has been performed using almost two million hadronic Z decays collected by the L3 experiment at LEP, yielding the result: Br(b → Xuℓν) = (3.3 ± 1.0 × 1.7) × 10-3. The first uncertainty is statistical and the second is systematic. The modulus of the Cabibbo-Kobayashi-Maskawa matrix element Vub extracted from this measurement is: |Vub| = (6.0+0.8 + 1.4-1.0 - 1.9 ± 0.2) × 10-3, where the uncertainties are statistical, systematic and theoretical, respectively. © 1998 Elsevier Science B.V.

Study of anomalous ZZγ and Zγγ couplings at LEP
, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, Vol: 436, Pages: 187-198, ISSN: 0370-2693We search for anomalous ZZγ and Zγγ couplings with the L3 detector at LEP. The analysis is based on the study of the process e+ e+ → Zγ at center-of-mass energies in the range 161 GeV < √s < 183 GeV. No evidence for anomalous effects is found. Limits at the 95% confidence level are set on the values of the eight possible anomalous couplings. Depending on the type of coupling new physics scales below 213 GeV to 1083 GeV are excluded. © 1998 Elsevier Science B.V. All rights reserved.

Search for sleptons in e<sup>+</sup>e<sup>-</sup> collisions at centre-of-mass energies up to 184 GeV ALEPH Collaboration
, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, Vol: 433, Pages: 176-194, ISSN: 0370-2693The data collected by the ALEPH experiment at LEP at centre-of-mass energies around 183 GeV are analysed to search for sleptons, the partners of leptons in supersymmetric theories. The previously published search for acoplanar leptons and missing energy has been updated. New searches have been developed to cover a wider range of slepton signals. These include single electrons, acoplanar leptons accompanied by two photons plus missing energy as well as particles with lifetime. No evidence for the production of any such particles is found. Slepton mass limits are reported within gravity mediated and gauge mediated SUSY breaking scenarios. © 1998 Elsevier Science B.V. All rights reserved.

, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, Vol: 431, Pages: 179-187, ISSN: 0370-2693Using the ARGUS detector at the e+e- storage ring DORIS II, we have measured the Michel parameters ρ, ξ, and ξδ for τ± → l± νν̄ decays in τ-pair events produced at center of mass energies in the region of the γ resonances. Using τ± → ρ±ν as spin analyzing tags, we find ρe = 0.68 ± 0.04 ± 0.08, ξe = 1.12 ± 0.20 ± 0.09, ξδe = 0.57 ± 0.14 ± 0.07, ρμ = 0.69 ± 0.06 ± 0.08, ξμ = 1.25 ± 0.27 ± 0.14 and ξδμ = 0.72 ± 0.18 ± 0.10. In addition, we report the combined ARGUS results on ρ, ξ, and ξδ using this work und previous measurements. © 1998 Elsevier Science B.V. All rights reserved.
