摘要：

We point out that a simple test of the mechanism of CP violation can be performed by a measurement of the CP asymmetries in exclusive and inclusive radiative rare decays. We show that the rate asymmetries Delta Gamma = Gamma (B- --> f gamma) - Gamma (B+ --> (f) over bar gamma) for certain final states f can be predicted in a theoretically clean way. Some implications for b --> sl(+)l(-) decays are discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
