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 ACP= +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.
