Description

We report observations of radiative B meson decays into the K+π-γ and K+π-π+γ final states. In the B0→K+π-γ channel, we present evidence for decays via an intermediate tensor meson state with a branching fraction of B(B0→K2*(1430)0γ)=[1.3±0.5(stat)±0.1(syst)]x10-5. We measure the branching fraction B(B+→K+π-π+γ)=[2.4±0.5(stat) -0.2+0.4(syst)]x10-5, in which the B+→K*0π+γ and B+→K+ρ0γ channels dominate. The analysis is based on a data set of 29.4 fb-1 recorded by the Belle experiment at the KEKB collider
