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.

Abstract:

The process t→H+b, H+→τ+v, τ+→hadrons+v and its charge conjugate are investigated by seeking an excess in number of observed τ's beyond that expected from the standard model under the assumption of e-τ universality. No such excess is found and new regions of the mH-mt plane are excluded for B(H+→τv) = 0.5 and 1.0. In addition, the ratio of couplings of the τ and e to the W is precisely measured as gwτ/gwe = 1.02 ± 0.04(stat.)±0.04(syst.). © 1992.
