Findings

The model describes HERA vector meson production data accurately.

Predictions for rapidity distributions in proton-proton and lead-lead collisions are provided.

Transverse momentum distributions in nuclear coherent production are analyzed.

Abstract

By using a Regge-pole model for vector meson production (VMP), successfully describing the HERA data, we analyse the correlation between VMP cross sections in photon-induced reactions at HERA and those in ultra-peripheral collisions at the Large Hadron Collider (LHC). The rapidity distributions of proton-proton collisions at 13~TeV and lead-lead collisions at 2.76 and 5.02 TeV are investigated. The transverse momentum distribution in nuclear coherent vector meson production is also addressed. Predictions for future experiments on production of $J/\psi$ and $\psi(2S)$ are presented.
