On the Charged Higgs Bosons Effects in the Top Quark Decays

The collider experiments at the Tevatron and the LHC provide us the possibility of probing the existence of a light charged Higgs boson. In this paper we study semi-leptonic decay of a polarized top quark via the charged Higgs boson (t(↑) → Hb → lνlb). It is shown that the asymmetry or spin correlation coefficient of the charged lepton depends on the tanβ andMH± and is quite different from the ...

Search for Charged Higgs Bosons from Top Quark Decays in ppÌ– Collisions at â‹ıs = 1:96 TeV

Direct search for charged higgs bosons in decays of top quarks.

We present a search for charged Higgs bosons in decays of pair-produced top quarks in pp collisions at sqrt[s] = 1.8 TeV recorded by the D0 detector at the Fermilab Tevatron collider. With no evidence for signal, we exclude most regions of the ( M(H+/-),tan(beta)) parameter space where the decay t--> H(+)b has a branching fraction >0.36 and B(H+/--->tau(nu)(tau)) is large.
