Radiative B meson decays into Kπγ and Kππγ final states
The radiative Β decays with the K+π-γ and K+π-π+γ final states were studied. For K+π-γ, B0→K2 *(1430)0- γ, B0→K*(1410)0γ, and non-resonant components were considered. It was found that only the first one is significant. For B+→ K+π-π+γ, the decay mode was observed and the branching fraction measured. The branching fractions were consistent with the sum of predicted rates of resonant decays.
