“…Experimental results on exclusive twophoton production of W + W − and + − pairs in γ γ interactions reported by the CMS and ATLAS Collaborations [9][10][11][12] have demonstrated that it is possible to measure such events with the experimental apparatus already available at the LHC, allowing for novel studies of QCD at very high energies and searches for Beyond Standard Model Physics (see, e.g., Ref.

In this paper we revisit the double vector meson production in γ γ interactions at heavy ion collisions and present, by the first time, predictions for the ρρ and J/ J/ production in proton-nucleus and proton-proton collisions. In order to obtain realistic predictions for rapidity distributions and total cross sections for the double vector production in ultra peripheral hadronic collisions we take into account the description of γ γ → V V cross section at low energies as well as its behavior at large energies, associated to the gluonic interaction between the color dipoles. Our results demonstrate that the double ρ production is dominated by the low energy behavior of the γ γ → V V cross section. In contrast, for the double J/ production, the contribution associated to the description of the QCD dynamics at high energies contributes significantly, mainly in pp collisions. Predictions for the RHIC, LHC, FCC, and CEPC-SPPC energies are shown.In recent years a series of experimental results from RHIC [1,2], Tevatron [3] and LHC [4][5][6][7][8][9][10][11][12] demonstrated that the study of photon-induced interactions in hadronic colliders is feasible and that it can be used to, among other things, improve our knowledge on the nuclear gluon distribution [13][14][15][16][17][18][19], on details of QCD dynamics [20][21][22][23][24][25][26][27][28][29][30], on the mechanism of quarkonium production [29][30][31][32][33][34][35][36], on the Odderon [37,38] and on the photon flux of the proton [39,40]. These data have stimulated the development of the theoretical description of these processes as well as the proposal of new forward detectors to be installed in the LHC [41,42].The basic idea in the photon-induced processes is that an ultra relativistic charged hadron (proton or nucleus) creates strong electromagnetic fields. A photon stemming from the electromagnetic field of one of the two colliding hadrons can interact with one photon coming from the other hadron a e-mails: barros@ufpel.edu.br;victor.goncalves@thep.lu.se (photon-photon process) or it can interact directly with the other hadron (photon-hadron process) [43][44][45][46][47][48]. In these processes the total cross section can be factorized in terms of the flux of equivalent photons from the hadron projectile and the photon-photon or photon-target production cross section. In this paper we will focus on two-photon interactions in hadronic collisions. Experimental results on exclusive twophoton production of W + W − and + − pairs in γ γ interactions reported by the CMS and ATLAS Collaborations [9][10][11][12] have demonstrated that it is possible to measure such events with the experimental apparatus already available at the LHC, allowing for novel studies of QCD at very high energies and searches for Beyond Standard Model Physics (see, e.g., Ref.
