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