Abstract

A search for the rare decay B0 → J/ψφ is performed using pp 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 1.1 × 10-7 at 90% confidence level is set on the branching fraction. © 2021Chinese Physical Society and the Institute of High Energy Physics of the Chinese Academy of Sciences and the Institute of Modern Physics of the Chinese Academy of Sciences and IOP Publishing Ltd.
