Exclusive vector meson photoproduction with a leading baryon in photon-hadron interactions at hadronic colliders

Exclusive vector meson photoproduction associated with a leading baryon (B = n, Delta(+), Delta(0)) in pp and pA collisions at RHIC and LHC energies is investigated using the color dipole formalism and taking into account nonlinear effects in the QCD dynamics. In particular, we compute the cross sections for rho, phi and J/Psi production together with a Delta and compare the predictions with those obtained for a leading neutron. Our results show that the V + Delta cross section is almost 30% of the V + n one. Our results also show that a future experimental analysis of these processes is, in principle, feasible and can be useful to study leading particle production.CNPqCAPESFAPERGSFAPESPINCT-FNAUniv Fed Sao Paulo, BR-01302907 Sao Paulo, BrazilUniv Fed Pelotas, Inst Fis & Matemat, High & Medium Energy Grp, Caixa Postal 354, BR-96010900 Pelotas, RS, BrazilUniv Sao Paulo, Inst Fis, CP 66318, BR-05315970 Sao Paulo, SP, BrazilUniv Paris Saclay, Inst Phys Theor, CNRS, CEA, F-91191 Gif Sur Yvette, FranceUniv Fed Sao Paulo, BR-01302907 Sao Paulo, BrazilFAPESP: 12/50984-4INCT-FNA: 464898/2014-5Web of Scienc
