Abstract

We report measurements of radiative B decays with Kηγ final states, using a data sample of 253 fb^-1 recorded at the Υ(4S) resonance with the Belle detector at the KEKB e⁺e^- storage ring. We observe B⁺→K⁺ηγ for the first time with a branching fraction of (8.4±1.5(stat)_-0.9 ^+1.2(syst))×10^-6 for M_Kη<2.4 GeV/c², and find evidence of B⁰→K ⁰ηγ. We also search for B→K₃*(1780) γ.
