Quarkonia production in ultra-peripheral PbPb collisions at LHCb
Measurements of coherent charmonium production cross sections together with their ratio in ultra-peripheral PbPb collisions are studied at a nucleon–nucleon centre-of-mass energy of 5.02 TeV. The differential cross-sections are measured as a function of rapidity and transverse momentum, separately....

| description | Measurements of coherent charmonium production cross sections together with their ratio in ultra-peripheral PbPb collisions are studied at a nucleon–nucleon centre-of-mass energy of 5.02 TeV. The differential cross-sections are measured as a function of rapidity and transverse momentum, separately. The photo-production of \(J/\psi \) mesons at low transverse momentum is studied in peripheral PbPb collisions and coherent \(J/\psi \) production in hadronic collisions is confirmed. These latest results significantly improve previous measurements and are compared with some theoretical predictions. |
