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