Abstract

We have studied exclusive, radiative B meson decays to charmless mesons in 9.7 × 106 B⊯B decays accumulated with the CLEO detector. We measure B(B⁰→ K^*0(892) γ)=(4.55^+0.72_-0.68± 0.34) × 10^-5and B(B⁺→ K^*+(892)γ)=(3.76^+0.89_-0.83± 0.28) × 10^-5. We have searched for CP asymmetry in B → K*(892)γ decays and measure A_CP= +0.08 ± 0.13 ± 0.03. We report the first observation of B → K^*₂(1430)γ decays with a branching fraction of (1.66^+0.59_-0.53± 0.13) × 10^-5. No evidence for the decays B → ργ and B⁰→ ωγ is found and we limit B(B → (ρ/ω)γ)/B(B → K*(892)γ) < 0.32 at 90% C.L.
