Search for the decay B{sup 0{yields}{gamma}{gamma}}

We report the result of a search for the rare decay B{sup 0{yields}{gamma}{gamma}} in 426 fb{sup -1} of data, corresponding to 226x10{sup 6} B{sup 0}B{sup 0} pairs, collected on the {Upsilon}(4S) resonance at the PEP-II asymmetric-energy e{sup +}e{sup -} collider using the BABAR detector. We use a maximum likelihood fit to extract the signal yield and observe 21{sub -12}{sup +13} signal events with a statistical significance of 1.8{sigma}. This corresponds to a branching fraction B(B{sup 0{yields}{gamma}{gamma}})=(1.7{+-}1.1(stat.){+-}0.2(syst.))x10{sup -7}. Based on this result, we set a 90% confidence level upper limit of B(B{sup 0{yields}{gamma}{gamma}})<3.2x10{sup -7}.
