Abstract:

In the most general two-Higgs doublet model with an approximate family symmetry and CP violation being originated solely from the relative phase of two vacuum expectation values, CP asymmetry in the decay

b\rightarrow s\gamma

may arise from the CP violation of the charged Higgs boson interactions with fermions. This asymmetry may be larger than in the standard model and can lie between

10~{-2}

and

10~{-1}

. The decay rate of

b\rightarrow s\gamma

is allowed to be smaller or larger than in the standard model
