Abstract

The radiative decays B → ργ and B0 → ωγ were studied. Charge-particle trajectories were measured in both a five-layer silicon vertex tracker (SCT) and 40-layer drift chamber (DCH). A ring-imaging Cherenkov detector (DIRC) was used for charged-particle identification. The 90% C.L. upper limits on the branching fractions are significantly lower than previous values and start to restrict the range indicated by SM predictions.
