CP Asymmetries in $b \to (s/d)$ 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 $ΔΓ= Γ(B^- \to f γ) - Γ(B^+ \to \bar{f} γ)$} for certain final states $f$ can be predicted in a theoretically clean way. Some implications for $b \to s \ell^+ \ell^-$ decays are discussed.
