Abstract

We demonstrate that study of large t vector meson photoproduction with rapidity gaps in ultraperipheral proton-ion and ion-ion collisions at LHC would allow to investigate the energy dependence of cross section of elastic scattering of a small dipole off the parton over a wide range of energies 10³ < s_{dipole - parton} < 10⁶ GeV² where this cross section is expected to change by a factor ≥ 20. The accessible energy range exceeds the one reached at HERA by a factor of 10 both in γp and in γA scattering. In addition, study of A-dependence of this process will allow to determine the t range where interaction of small dipoles gives the dominant contribution and to investigate effects of absorption for the propagation of ultrarelativistic small q q dipoles through the nuclear media and probe in a novel way onset of the black disk regime.
