CP violation in the decay b-->s gamma in the two-Higgs-doublet model.

In the most general two-Higgs-doublet model with an approximate family symmetry and [ital CP] violation originating solely from the relative phase of two vacuum expectation values, [ital CP] asymmetry in the decay [ital b][r arrow][ital s][gamma] may arise from the [ital 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[sup [minus]2] and 10[sup [minus]1]. The decay rate of [ital b][r arrow][ital s][gamma] is allowed to be smaller or larger than in the standard model.
