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 (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. ? 2019 authors.
