Measurement of the B-0 -> K-2(*)(1430)(0)gamma and B+-> K-2(*)(1430)(+)gamma branching fractions
We have investigated the exclusive, radiative B meson decays to K 2*(1430) in 89 × 106 BB̄ events with the BABAR detector at the PEP-II storage ring. We measure the branching fractions B(B0 → K2*(1430)0γ) = (1.22 ± 0.25 ± 0.10) × 10-5 and B(B+ → K2*(1430)+γ) = (1.45 ± 0.40 ± 0.15) × 10-5, where the...

| description | We have investigated the exclusive, radiative B meson decays to K 2*(1430) in 89 × 106 BB̄ events with the BABAR detector at the PEP-II storage ring. We measure the branching fractions B(B0 → K2*(1430)0γ) = (1.22 ± 0.25 ± 0.10) × 10-5 and B(B+ → K2*(1430)+γ) = (1.45 ± 0.40 ± 0.15) × 10-5, where the first error is statistical and the second systematic. In addition, we measure the CP-violating asymmetry A CP[B0 → K2*(1430) 0γ] = -0.08 ± 0.15 ± 0.01. |
