Title: Study of Exclusive Radiative B Meson Decays

Abstract

We have studied exclusive, radiative B meson decays to charmless mesons in 9.7x10{sup 6} BB(bar sign) decays accumulated with the CLEO detector. We measure B(B{sup 0}{yields}K{sup *0}(892){gamma}) =(4.55{sup +0.72}{sub -0.68}{+-}0.34) x10{sup -5} and B(B{sup +}{yields}K{sup *+}(892){gamma}) =(3.76{sup +0.89}{sub -0.83}{+-}0.28) x10{sup -5} . We have searched for CP asymmetry in B{yields}K{sup *}(892){gamma} decays and measure A{sub CP}=+0.08{+-}0.13{+-}0.03 . We report the first observation of B{yields}K{sup *}{sub 2}(1430){gamma} decays with a branching fraction of (1.66{sup +0.59}{sub -0.53}{+-}0.13) x10{sup -5} . No evidence for the decays B{yields}{rho}{gamma} and B{sup 0}{yields}{omega}{gamma} is found and we limit B(B{yields}({rho} /{omega}){gamma})/B (B{yields}K{sup *}(892) {gamma})<0.32 at 90% C.L.
