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

摘要

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/psi, meson proton lead ultraperipheral collisions. The predictions give a good description to the experimental data of ALICE. The rapidity distributions of phi, omega and psi(2s) mesons in proton-lead ultraperipheral collisions are also presented in this paper. (C) 2017 Elsevier B.V. All rights reserved.
