Measurement of branching fractions and CP and isospin asymmetries for B -> K-*gamma

Measurement of branching fractions and CP and isospin asymmetries for B -> K-*gamma

The branching fractions of the decays B0 → K*0 γ and B+ → K*+ γ are measured using a sample of 88 × 106BB̄ events collected with the BABAR detector at the PEP-II asymmetric-energy e +e- collider. We find B(B0 → K* γ) = [3.92 ± 0.20(stat) ± 0.24(syst)] × 10 -5, B(B+ → K*+ γ) = [3.87 ± 0.28(stat) ± 0....
