Abstract

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 711fb−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.
