A search for t-quark decay into charged Higgs, t --> H+b, with the charged Higgs decaying via the H+ --> tau+nu-tau mode, has been done in proton-antiproton collisions at square root s = 0.63 TeV with the UA1 experiment. No evidence for this decay has been observed. Mass limits at 95% and 90% CL for the t-quark and the charged Higgs are presented. The results have also been interpreted in terms of the tan beta-parameter of a two-doublet Higgs sector.

Abstract
A search for t-quark decay into charged Higgs, t --> H+b, with the charged Higgs decaying via the H+ --> tau+nu-tau mode, has been done in proton-antiproton collisions at square root s = 0.63 TeV with the UA1 experiment. No evidence for this decay has been observed. Mass limits at 95% and 90% CL for the t-quark and the charged Higgs are presented. The results have also been interpreted in terms of the tan beta-parameter of a two-doublet Higgs sector.File in questo prodotto:
