چکیده

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 provide analytical formulae for the unpolarized and polarized rates for m b = 0 and for m b = 0. For m b = 0 our closed-form expressions for the unpolarized and polarized rates become rather compact.

Radiative Corrections to Top Quark Decay into Charged Higgs at the Tevatron

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 ...

Corrections of Order O ( G F α s m 2 t ) to the Higgs Decay Rate Γ ( H →

QCD corrections to the electroweak one-loop result for the partial width Γ(H → b ¯ b) are studied. For the decay channel into bottom quarks the rate is affected by a virtual top quark through electroweak interactions. The calculation of QCD corrections to this quantity is performed for an intermediate range Higgs mass in the heavy top mass limit. The leading correction of order O(G F α s m 2 t)...

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...

QCD corrections to the charged Higgs decay of a heavy quark

We present an analytic formula for the O(α s) corrections to the decay t → H + b for nonzero m H and m b. The Equivalence Theorem is used to relate these corrections to those for the process t → W + b. Contrary to previously published results we find that the effect of the b quark mass is negligible for a wide range of m t , m H and tan β.

Electroweak 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...
