| Abstract | We report the result of a search for the rare decay B-0 -> gamma gamma in 426 fb(-1) of data, corresponding to 226 x 10(6) B-0(B) over bar (0) pairs, collected on the Y(4S) resonance at the PEP-II asymmetric-energy e(+)e(-) collider using the BABAR detector. We use a maximum likelihood fit to extract the signal yield and observe 21(-12)(+13) signal events with a statistical significance of 1.8 sigma. This corresponds to a branching fraction B(B-0 -> gamma gamma) = (1.7 +/- 1.1(stat.) +/- 0.2(syst.)) X 10(-7). Based on this result, we set a 90% confidence level upper limit of B(B-0 -> gamma gamma) < 3.2 X 10(-7). | ||||
