Exclusive vector meson photoproduction in fixed-target collisions at the LHC

The exclusive ρ , ω and J / Ψ photoproduction in fixed-target collisions at the LHC is investigated. We estimate, for the first time, the rapidity and transverse momentum distributions of the vector meson photoproduction in pHe , pAr , PbHe and PbAr fixed-target collisions at the LHC using the STARlight Monte Carlo and present our results for the total cross sections. Predictions for the kinematical range probed by the LHCb detector are also presented. Our results indicate that the experimental analysis of this process in fixed-target collisions at the LHC is feasible. Such future analysis will probe the QCD dynamics in a kinematical range complementary to that studied in the collider mode.
