Search for B0 → X(3872)γ

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...

Description
Summary: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−)
