A SEARCH FOR CHARGED HIGGS FROM TOP QUARK DECAY AT THE CERN (P)BAR-P COLLIDER

Abstract:
The process t→H+b, H+→τ+ν, τ+→hadrons+ν̄ 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+→τν) = 0.5 and 1.0. In addition, the ratio of couplings of the τ and e to the W is precisely measured as gτ w/ge w = 1.02±0.04(stat.)±0.04(syst.).
