Abstract
The first study of J/ψφ production in diffractive processes in proton-proton collisions is presented. The study is based on an LHCb dataset recorded at center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5 fb-1. The data disfavor a nonresonant J/ψφ production but are consistent with a resonant model including several resonant states observed previously only in B+→J/ψφK+ decays. The χc0(4500) state is observed with a significance over 6σ and the χc1(4274) is confirmed with a significance of more than 4σ.
