Measurement of B -> K-*(892)gamma Branching Fractions and CP and Isospin Asymmetries

Abstract:
We present an analysis of the decays B0→K*0(892)γ and B+→K*+(892)γ using a sample of about 383×106 BB̄ events collected with the BABAR detector at the PEP-II asymmetric energy B factory. We measure the branching fractions B(B0→K*0γ)=(4. 47±0.10±0.16)×10-5 and B(B+→K*+γ)=(4. 22±0.14±0.16)×10-5. We constrain the direct CP asymmetry to be -0.033
