Abstract
We report measurements of radiative B decays with Kηγ final states, using a data sample of 253fbâ1 recorded at the Ï(4S) resonance with the Belle detector at the KEKB e+eâ storage ring. We observe B+âK+ηγ for the first time with a branching fraction of (8.4±1.5(stat)â0.9+1.2(syst))Ã10â6 for MKη<2.4 GeV/c2, and find evidence of B0âK0ηγ. We also search for BâK3â(1780)γ.
