Vector meson production in coherent hadronic interactions : update on predictions for energies available at the BNL Relativistic Heavy Ion Collider and the CERN Large Hadron Collider

Abstract

In this Rapid Communication we update our predictions for the photoproduction of vector mesons in coherent pp and AA collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies using the color dipole approach and the Color Glass Condensate formalism. In particular, we present our predictions for the first run of the LHC at half energy and for the rapidity dependence of the ratio between the J/Ψ and ρ cross sections at RHIC energies.
