We have investigated the exclusive, radiative B meson decays to K2*(1430) in 89×106 BB̅ 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 ACP[B0→K2*(1430)0γ]=-0.08±0.15±0.01.

Abstract
We have investigated the exclusive, radiative B meson decays to K2*(1430) in 89×106 BB̅ 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 ACP[B0→K2*(1430)0γ]=-0.08±0.15±0.01.File in questo prodotto:
