Abstract

The mixing-induced CP asymmetries in B{yields}K*{gamma}{yields}K{sub S}{pi}{sup 0}{gamma} and B{yields}K*{gamma}{yields}K{sub L}{pi}{sup 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{sub K{sub S}}{sub {pi}{sup 0}}{sub {gamma}}=-S{sub K{sub L}}{sub {pi}{sup 0}}{sub {gamma}}=-(3.5{+-}1.7)x10{sup -2}.
