Radiative Corrections to Top Quark Decay into Charged Higgs at the Tevatron
نویسندگان
چکیده
We present the computation of the leading one-loop electroweak radiative corrections to the non-standard top quark decay width Γ(t → H b), using a physically motivated definition of tanβ. We find that the corrections are large, both in the Minimal Supersymmetric Standard Model (MSSM) and the Two-Higgs-Doublet Model (2HDM). These corrections have an important effect on the interpretation of the Tevatron data, leading to the non-existence of a model-independent bound in the tan β −MH± plane. Talk presented at the IVth International Symposium on Radiative Corrections (RADCOR 98), Barcelona, September 8-12, 1998. To appear in the proceedings, World Scientific, ed. J. Solà.

Top quark and charged Higgs at the Tevatron-Run II
We shortly review the top quark decay into charged Higgs, and present new results on its production at the upgraded Tevatron. We have computed the MSSM cross-section for single charged Higgs in association with the top quark beyond the regime of on-shell t t̄ production followed by the decay t → H b,. Our results are higher than recent results in the literature. In the case where H belongs to th...
متن کاملO ( α s ) radiative corrections to polarized top decay into a charged Higgs t ( ↑ ) → H + + b
O(α s) radiative corrections to polarized top decay into a charged Higgs t(↑) → H + + b Abstract We calculate the O(α s) radiative corrections to polarized top quark decay into a charged Higgs and a bottom quark in Two-Higgs-Doublet-Models for nonzero bottom quark masses m b = 0. The radiative corrections to the polarization asymmetry parameter of the decay can become as large as 25 %. We provi...
متن کاملStrangephilic Higgs Bosons in the MSSM
We suggest a new CPX-derived scenario for the search of strangephilic MSSM Higgs bosons at the Tevatron and the LHC, in which all neutral and charged Higgs bosons decay predominantly into pairs of strange quarks and into a strange and a charm quark, respectively. The proposed scenario is realized within a particular region of the MSSM parameter space and requires large values of tanβ, where thr...
متن کاملElectroweak corrections to decays involving a charged Higgs boson.
We present complete one-loop radiative corrections to the decay rate of a top quark into a charged Higgs boson and a bottom quark, and for the decay of a charged Higgs boson into leptons. The results are discussed in the framework of the two Higgs boson extension of the Standard Model suggested by supersymmetry. The effect of electroweak corrections after exclusion of universal corrections ∆r i...
متن کاملSignatures for the Charged Higgs Decay of the Top Quark at the Tevatron
We investigate the effect that a charged Higgs decay channel for the top quark has on the signature for top quark pair production at the Tevatron. The branching ratios for the various multijet and multilepton final states arising from tt production are obtained for a wide range of values for tanβ and the charged Higgs boson mass. In addition, the effect of the charged Higgs decay of the top qua...
