Measurement of B→K∗(892)γ branching fractions and CP and isospin asymmetry

We present an analysis of the decays B0→K*0(892)γ and B+→K*+(892)γ using a sample of about 383×106 B¯¯¯B events collected with the BABAR detector at the PEP-II symmetric energy B factory. We measure the branching fractions B(B0→K*0γ)=(4.47±0.10±0.16)×1− 5 and B (B+→K*+γ)=(4.22±0.14±0.16)×10−5. We co...
