Determination of the tau-neutrino helicity
, Physics Letters B, Vol: 250, Pages: 164-171, ISSN: 0370-2693Using the ARGUS detector at the DORIS II e+e- storage ring we measured for the first time the τ neutrino helicity from a parity violating asymmetry in the τ decay into three charged pions. From the measured asymmetry we derived the normalized product of the axial and vector coupling constant 2gAgv/ (gA2 + gV2) = 1.14±0.34-0.170.34, which is in good agreement with the standard model prediction. © 1990.

Study of inclusive semileptonic B meson decays
, Physics Letters B, Vol: 249, Pages: 359-365, ISSN: 0370-2693Using the ARGUS detector at the e+e- storage ring DORIS-II, we have measured the inclusive semileptonic decays of B-mesons into electrons and muons. The data originate from 220.5 events/pb on the Υ{hooked}(4S) resonance. We find BR (B→e+veX = (10.3 ± 0.6 ± 0.2)% and BR (B→μ+vμX) = (10.0 ± 0.6 ± 0.2)% using the model of Altarelli et al. for extrapolating over all lepton momenta, and BR (B→e+veX) = (9.9±0.6)%, BR(B→μ+vμX) = (9.7±0.6)% using the model of Grinstein et al. For semileptonic decays into baryons, we obtain an upper limit of BR (B→pe+vX)<0.16%(90%CL). © 1990.

Measurement of Ξ<inf>c</inf> production in e<sup>+</sup>e<sup>-</sup> annihilation at 10.5 GeV center-of-mass energy
, Physics Letters B, Vol: 247, Pages: 121-126, ISSN: 0370-2693Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we have observed production of the charmed-strange baryon Ξc+ and its neutral isospin partner, the Ξc0. The Ξc+ was reconstructed in the final state Ξ-π+π+, while the Ξc0 was seen in decay to Ξ-π+ and Ξ-π+π+π-. The average Ξc fragmentation spectrum has been determined, as well as the production cross section times branching ratio for each decay mode. The charged and neutral masses were measured to be 2465.1 ± 3.6 ± 1.9 MeV/c2 and 2472.1 ± 2.7 ± 1.6 MeV/c2 respectively, corresponding to a mass-splitting, M(Ξc+) - M(Ξc0), of -7.0±4.5±2.2 MeV/c2. © 1990.

A spectrometer for muon scattering at the Tevatron
, Nuclear Inst. and Methods in Physics Research, A, Vol: 291, Pages: 533-551, ISSN: 0168-9002In this paper the spectrometer constructed by the E665 Collaboration is described. The spectrometer was built during the period 1982-87 and the first data were taken during the 1987-88 Fixed Target run of the Fermi National Accelerator Laboratory (FNAL) Tevatron. This is the first of a series of runs in which a comprehensive program of high energy muon scattering experiments will be performed. © 1990.

Search for hadronic b→u decays
, Physics Letters B, Vol: 241, Pages: 278-282, ISSN: 0370-2693Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we searched for b→u transitions in exclusive hadronic B meson decays. A systematic analysis of B decays into pions has been performed for decay modes with 2-7 pions in the final state. In none of the decays a positive signal was observed. The upper limits obtained on various branching ratios are consistent with the current model predictions. © 1990.
