Abstract: (APS)

We report the results of a search for the decay B0→X(3872)(→J/ψπ+π-)γ. The analysis is performed on a data sample corresponding to an integrated luminosity of 711 fb-1 and containing 772×106BB¯ pairs, collected with the Belle detector at the KEKB asymmetric-energy e+e- collider running at the ϒ(4S) resonance energy. We find no evidence for a signal and place an upper limit of B(B0→X(3872)γ)×B(X(3872)→J/ψπ+π-)<5.1×10-7 at 90% confidence level.
