Measurement of the B0 -> K2*(1430)0 gamma and B+ -> K2*(1430)+ gamma branching fractions
Abstract
We have investigated the exclusive, radiative B meson decays to K2*(1430) in 89* 106 BBbar events with the BaBar detector at the PEP-II storage ring. We measure the branching fractions BR(B0 -> K2*(1430)0 gamma) = (1.22 +-0.25 +-0.10)*10(-5) and BR(B+ -> K2*(1430)+ gamma) = (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 ACP(B0 -> K2*(1430)0 gamma) = -0.08 +- 0.15 +- 0.01.
