Abstract When new CP-violating interactions are dominated by flavor changing neutral particle exchanges, which may occur in many extensions of the standard model, we examine a type-3 two-Higgs-doublet model and find that direct CP asymmetries can be as large as about 25% . Time-dependent and time-integrated mixing-induced CP asymmetries up to 85 and 40%, respectively, are possible without conflict with other constraints. It mainly requirs an enhanced chromo-magnetic dipole b →sg decay to be close to the present experimental bound.
