title = "Measurement of B → K∗(892)γ 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 BB 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 < A(B → K∗ γ) < 0.028 and the isospin asymmetry to be 0.017 < δ0- < 0.116, where the limits are determined by the 90% confidence interval and include both the statistical and systematic uncertainties.",
