Abstract

At forward rapidities and high energies we expect to probe the non-linear regime of Quantum Chromodynamics (QCD). One of the most promising observables to constrain the QCD dynamics in this regime is exclusive vector meson photoproduction (EVMP). We study the EVMP in association with a leading baryon (product of the proton dissociation) in photon-hadron interactions that take place in pppp and ppPb collisions at large impact parameters. We present the rapidity distributions for ρ\rho and J/ψJ/\psi photoproduction in association with a leading baryon (neutron and delta states) at LHC run 2 energies. Our results show that the V+ΔV + \Delta cross section is almost 30 % of the V+nV + n one. Our results also show that a future experimental analysis of these processes is, in principle, feasible and can be useful to study the leading particle production.
