摘要：

According to the standard CKM model, the rare decays of the B-mesons can produce CP-violating asymmetries that may be accessible to experiment. I investigate the radiative decays b --> s-gamma and b --> dy, at the quark level, and I find asymmetries of the order (0.1-1)% and (1-10)%, respectively. I use a modified formalism to calculate the asymmetries, that singles out the relevant contributions, and simplifies handling the important QCD corrections to the amplitudes.
