Abstract:

Neutral strange particle production in {Mathematical expression} Ne charged current interactions is studied using the bubble chamber BEBC, exposed to the CERN SPS antineutrino wide band beam. From a sample of 1191 neutral strange particles, the inclusive production rates are determined to be (15.7±0.8)% for K0 mesons, (8.2±0.5)% for Λ, (0.4±0.2)% for {Mathematical expression} and (0.6±0.3)% for Σ0 hyperons. The inclusive production properties of K0 mesons and Λ hyperons are investigated. The Λ hyperons are found to be polarized in the production plane. © 1992 Springer-Verlag.

Bound on the tau neutrino magnetic moment from the BEBC beam dump experiment

Physics Letters B 280:1-2 (1992) 153-158

Abstract:

We have searched for electrons scattered in the forward direction by neutrinos produced by dumping a 400 GeV/c proton beam on a copper target. We estimate the number of tau neutrinos produced from the decays of Ds mesons in the dump. The data limit the possible magnetic moment of tau neutrinos to be below 5.4×10-7 ωB. This rules out the suggestion that tau neutrinos of mass O(MeV) constitute the dark matter in the universe. © 1992.

Abstract:

The coherent production of 3π systems by charged current antineutrino interactions on neon nuclei is studied in the bubble chamber BEBC exposed to the CERN SPS wide band beam. The coherent signal is attributed mainly to (ρπ) production, where the (ρπ) system is either non-resonant or comes from the decay of a1 mesons. The kinematical variables and the total cross section are compared with the predictions of the meson dominance model. © 1991 Springer-Verlag.
