Large t diffractive J/ψ photoproduction with proton dissociation in ultraperipheral pA collisions at LHC

We evaluate the large momentum transfer J/ψ photoproduction with rapidity gaps in ultraperipheral proton-ion collisions at the LHC which provides an effective method of probing dynamics of large t elastic hard QCD Pomeron interactions. It is shown that the experimental studies of this process would allow to investigate the energy dependence of cross section of elastic scattering of a small cc¯ dipole off the gluon over a wide range of invariant energies 103
