摘要：

We report the results of a search for the decay B-0 -> X(3872) (-> J/psi pi(+)pi(-))gamma. The analysis is performed on a data sample corresponding to an integrated luminosity of 711 fb(-1) and containing 772 x 10(6)B (B) over bar pairs, collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider running at the Upsilon(4S) resonance energy. We find no evidence for a signal and place an upper limit of B(B-0 -> X(3872)gamma) x B(X(3872) -> J/psi pi(+)pi(-) < 5.1 x 10(-7) at 90% confidence level.
