  Title Observation of Exotic J/ψφ Resonant Structure in Diffractive Processes in Proton-Proton Collisions Type Journal Article
  Year 2025 Publication Physical Review Letters Abbreviated Journal Phys. Rev. Lett.

  Abstract The first study of J/psi phi 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/psi phi production but are consistent with a resonant model including several resonant states observed previously only in B+ -> J/psi phi K+ decays. The chi(c0)(4500) state is observed with a significance over 6 sigma and the chi(c1) (4274) is confirmed with a significance of more than 4 sigma.
