Hard gamma emission from b-decay and the Higgs boson doublet model

The possible contribution to b→ s + γ decay of the charged physical Higgs boson is discussed in models with two Higgs boson doublets. It is shown that the extra charged Higgs boson exchange in the one-loop level significantly enhance the b→ s+ γ decay over the standard theory which has one Higgs bos...

Description
Summary:The possible contribution to b→ s + γ decay of the charged physical Higgs boson is discussed in models with two Higgs boson doublets. It is shown that the extra charged Higgs boson exchange in the one-loop level significantly enhance the b→ s+ γ decay over the standard theory which has one Higgs boson doublet. The possible detection of hard gamma from b→ s+ γ decay through ϒ‴ in the e +e − annihilation experiments will give rigorous restrictions on the possibility of two Higgs boson doublet models The b→ s+ γ decay is also briefly discussed.
