Effects of charged Higgs bosons on the processes b → sγ, b → sg* and b → sl+l-

Effects of charged Higgs bosons (H+) on various loop-induced processes in the B-meson system are discussed, within the framework of two Higgs doublet models (2HDMs). The H+ contribution to the magnetic moment form factor turns out to be very significant and it can distinguish between the two types of 2HDMs. Even with constraints from Bd mixing, both strong enhancements or strong suppressions (in b → sγ) of decay rates are possible. Thus, information from these modes is competitive with, and may soon surpass, restrictions on 2HDMs from Bd mixing. Since (inclusive) b → sγ and b → sg* at current limits are not excluded, continued effort to detect them is encouraged. (orig.)
