Regge phenomenology and coherent photoproduction of J/ψ in peripheral heavy ion collisions

Abstract

By using models based on Regge phenomenology we analyze the coherent photoproduction of charmonium in peripheral heavy-ion collisions at the Large Hadron Collider (LHC). The centrality dependence is investigated and compared to the experimental results for coherent J/ψ production in lead-lead LHC runs at the energies of 2.76 and 5.02 TeV. Theoretical uncertainties and possible limitations of the formalism are also discussed.
