Publisher	Chinese Physics C
Abstract	A search for the rare decay B~0→J/ψφ is performed using pp collision data collected with the LHCb detector 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 1.1 x 10~(-7) at 90% confidence level is set on the branching fraction.
