Double vector meson production in photon - hadron interactions at hadronic colliders

TL;DR

This paper investigates double vector meson production in photon-hadron interactions at hadronic colliders, providing predictions for cross sections and rapidity distributions, and analyzing the dominant production mechanisms across different collision types.

Contribution

It offers the first detailed predictions for double vector meson production considering the double scattering mechanism at LHC energies, comparing with two-photon interactions.

Findings

Double scattering dominates in PbPb collisions for $ ho ho$ and $J/\Psi J/\Psi$ production.

Two-photon mechanism is dominant in pp collisions.

Analysis of $ ho J/\Psi$ production can help constrain the double scattering mechanism.

Abstract

In this paper we analyse the double vector meson production in photon -- hadron ($\gamma h$) interactions at $pp/pA/AA$ collisions and present predictions for the $\rho\rho$, $J/\Psi J/\Psi$ and $\rho J/\Psi$ production considering the double scattering mechanism. We estimate the total cross sections and rapidity distributions at LHC energies and compare our results with the predictions for the double vector meson production in $\gamma \gamma$ interactions at hadronic colliders. We present predictions for the different rapidity ranges probed by the ALICE, ATLAS, CMS and LHCb Collaborations. Our results demonstrate that the $\rho\rho$ and $J/\Psi J/\Psi$ production in $PbPb$ collisions is dominated by the double scattering mechanism, while the two - photon mechanism dominates in $pp$ collisions. Moreover, our results indicate that the analysis of the $\rho J/\Psi$ production at LHC can be useful to constrain the double scattering mechanism.
