Title: SEARCH FOR THE EXCLUSIVE RADIATIVE DECAYS B ---> RHO GAMMA AND B0 ---> OMEGA GAMMA

Abstract

A search for the exclusive radiative decays B {yields} {rho}(770){gamma} and B{sup 0} {yields} {omega}(782){gamma} is performed on a sample of 84 million B{bar B} events collected by the BaBar detector at the PEP-II asymmetric e{sup +}e{sup -} collider. No significant signal is seen in any of the channels. They set preliminary upper limits of {Beta}[B{sup 0} {yields} {rho}{sup 0}{gamma}] < 1.4 x 10{sup -6}, {Beta}[B{sup +} {yields} {rho}{sup +}{gamma}] < 2.3 x 10{sup -6} and {Beta}[B{sup 0} {yields} {omega}{gamma}] < 1.2 x 10{sup -6} at 90% Confidence Level. Combining these into a single limit on the generic process B {yields} {rho}{gamma}, they find the preliminary limit {Beta}[B {yields} {rho}{gamma}] < 1.9 x 10{sup -6} corresponding, to a limit of {Beta}[B {yields} {rho}{gamma}]/{Beta}[B {yields} K*{gamma}] < 0.047 at 90% Confidence Level.
