DOI:https://doi.org/10.2172/839728· OSTI ID:839728

We perform a search for the exclusive radiative decay B{sup 0} {yields} {phi}{gamma}, which is dominated by {bar b}d annihilation, in a sample of 124 million B{bar B} events collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage ring at SLAC. No significant signal is seen. We set an upper limit on the branching fraction of {Beta}(B{sup 0} {yields} {phi}{gamma}) < 8.5 x 10{sup -7} at the 90% confidence level.
