Measurement of the Branching Fraction of the Exclusive Decay B0 --> K*0gamma
The b {yields} s{gamma} transition proceeds by a loop penguin diagram. It may be used to measure precisely the couplings of the top quark and to search for the effects of any new particles appearing in the loop. We present a preliminary measurement of the branching fraction of the exclusive decay, B{sup 0} {yields} K*{sup 0}{gamma}. They use 8.6 x 10{sup 6} B{bar B} decays to measure B(B{sup 0} {yields} K*{sup 0}{gamma}) = (5.4 {+-} 0.8 {+-} 0.5) x 10{sup -5}.
