TTP01-08 CP Asymmetries in b-->(s/d) gamma Transitions as a Test of CKM-CP Violation

(s/d) gamma Transitions as a Test of CKM-CP Violation > 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 \mbox{ $\Delta \Gamma = \Gamma(B^- \to f \gamma) - \Gamma(B^+ \to \bar{f} \gamma)$} for certain final states $f$ can be predicted in a theoretically clean way. Some implications for $b \to s \ell^+ \ell^-$ decays are discussed.
