Study of exclusive radiative B meson decays

We have studied exclusive, radiative B meson decays to charmless mesons in 9.7 X 10(6) B (B) over bar decays accumulated with the CLEO detector. We measure B(B-0 --> K*(0)(892)gamma) = (4.55(-0.68)(+0.72) +/- 0.34) X 10(-5) and B(B+ --> K*(+)(892)gamma) = (3.76(-0.83)(+0.89) +/- 0.28) X 10(-5). We have searched for CP asymmetry in B --> K*(892)gamma decays and measure A(CP) = + 0.08 +/- 0.13 +/- 0.03. We report the first observation of B --> K-2*(1430)gamma decays with a branching fraction of (1.66(-0.53)(+0.59) +/- 0.13) x 10(-5). No evidence for the decays B --> rho gamma and B-0 --> omega gamma is found and we limit B(B --> (rho/omega)gamma)/B(B --> K*(892)gamma) < 0.32 at 90% C.L.
