Abstract

The branching fractions of the decays B0→K*0γ and B+→K*+γ are measured using a sample of 88×106BB̅ events collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider. We find B(B0→K*0γ)=[3.92±0.20(stat)±0.24(syst)]×10-5, B(B+→K*+γ)=[3.87±0.28(stat)±0.26(syst)]×10-5. Our measurements also constrain the direct CP asymmetry to be -0.074<A(B→K*γ)<0.049 and the isospin asymmetry to be -0.046<Δ0-<0.146, both at the 90% confidence level.
