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....

| description | 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) ± 0.26(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. |
