Search for the rare decay B0 → J/ψphgr*

A search for the rare decay  is performed using  collision data collected with the LHCb dete-ctor at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb−1. No significant signal of the decay is observed and an upper limit of  at 90% confidence level is set on the branching fraction.
