Exclusive photoproduction of vector mesons in proton–lead ultraperipheral collisions at the LHC

Abstract

Rapidity distributions of vector mesons are computed in dipole model proton–lead ultraperipheral collisions (UPCs) at the CERN Larger Hadron Collider (LHC). The dipole model framework is implemented in the calculations of cross sections in the photon–hadron interaction. The bCGC model and Boosted Gaussian wave functions are employed in the scattering amplitude. We obtain predictions of rapidity distributions of J/ψ meson proton–lead ultraperipheral collisions. The predictions give a good description to the experimental data of ALICE. The rapidity distributions of ϕ, ω and ψ(2s) mesons in proton–lead ultraperipheral collisions are also presented in this paper.
