  • 摘要:We have studied radiative B meson decays into higher kaonic resonances decaying into a two-body or three-body nal state, using a data sample of 21:3 fb −1 recorded at the (4S) resonance with the Belle detector at KEKB. For the two-body nal state, we extract the B ! K 2 (1430) component from an analysis of the helicity angle distribution, and obtain B(B0 ! K 2 (1430)0) = (1:260:660:10)10−5. For the three-body nal state, we observe a B ! K signal that is consistent with a mixture of B ! K and B ! K for the rst time.
