Abstract
The process t-H+b, H+ --> tau+nu, tau+ --> hadrons + nuBar and its charge conjugate are investigated by seeking an excess in number of observed theta's beyond that expected from the standard model under the assumption of e-tau-universality. No such excess is found and new regions of the m(H)-m(t) plane are excluded for B(H+ --> tau(nu) = 0.5 and 1.O. In addition, the ratio of couplings of the tau and eto the W is precisely measured as g-tau(W)/g-e(W) = 1.02 +/- 0.04(stat.) +/- 0.04(syst.).File in questo prodotto:
