摘要：

The mixing-induced CP asymmetries in B -> K-*gamma -> K-S pi(0)gamma and B -> K-*gamma -> K-L pi(0)gamma are expected to be small within the standard model. So they are among the most promising decay modes to test the standard model. In this paper, we compute the mixing-induced CP asymmetries in these decay modes, within the framework of the standard model, using perturbative QCD, and our conclusion is S-KS pi(0)gamma=-S-KL pi(0)gamma=-(3.5 +/- 1.7)x10(-2).
