In this letter we study the photoproduction of heavy quarks and vector mesons in coherent proton-nucleus (pA) interactions for RHIC LHC energies analyze if these processes can be used to determine QCD dynamics at high energies. The integrated cross section rapidity distribution are estimated using Color Glass Condensate (CGC) formalism. A comparison with linear predictions is also presented. Our results indicate that nonlinear proven those reactions, which well suited studing saturation effects.
