Search for radiative penguin decays B+->rho(+)gamma, B-0 ->rho(0)gamma, and B-0 ->omega gamma

A search for the decays B-->rho(770)gamma and B-0-->omega(782)gamma is performed on a sample of 211x10(6) Y(4S)-->B (B) over bar events collected by the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)e(-) storage ring. No evidence for the decays is seen. We set the following limits on the individual branching fractions: B(B+-->rho(+)gamma)<1.8x10(-6), B(B-0-->rho(0)gamma)<0.4x10(-6), and B(B-0-->omegagamma)<1.0x10(-6) at the 90% confidence level. We use the quark model to limit the combined branching fraction (B) over bar [B-->(rho/omega)gamma]<1.2x10(-6), from which we determine a constraint on the ratio of Cabibbo-Kobayashi-Maskawa matrix elements |V-td|/|V-ts|.

Abstract: A search for the decays B-->rho(770)gamma and B-0-->omega(782)gamma is performed on a sample of 211x10(6) Y(4S)-->B (B) over bar events collected by the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)e(-) storage ring. No evidence for the decays is seen. We set the following limits on the individual branching fractions: B(B+-->rho(+)gamma)<1.8x10(-6), B(B-0-->rho(0)gamma)<0.4x10(-6), and B(B-0-->omegagamma)<1.0x10(-6) at the 90% confidence level. We use the quark model to limit the combined branching fraction (B) over bar [B-->(rho/omega)gamma]<1.2x10(-6), from which we determine a constraint on the ratio of Cabibbo-Kobayashi-Maskawa matrix elements |V-td|/|V-ts|.
