Abstract

In this paper we analyze the double vector meson production in photon–hadron (γh) interactions at pp / pA / AA collisions and present predictions for the ρρ, J/ Ψ J/ Ψ , and ρJ/ Ψ 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 γγ 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 ρρ and J/ Ψ J/ Ψ production in PbPb collisions is dominated by the double-scattering mechanism, while the two-photon mechanism dominates in pp collisions.... (More)

Our results demonstrate that the ρρ and J/ Ψ J/ Ψ 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 ρJ/ Ψ production at LHC can be useful to constrain the double-scattering mechanism.
