Diffractive vector meson production at large t in coherent hadronic interactions at CERN LHC

The diffractive vector meson photoproduction with hadron dissociation in coherent hadron-hadron interactions at LHC energies is studied assuming that the color singlet t-channel exchange carries large momentum transfer. We estimate the rapidity distribution and total cross-section for the processes pp →pVX and PbPb → PbVX(V=ρ or Υ) considering the non-forward solution of the BFKL equation at high energy and large momentum transfer. Our results indicate that the experimental identification of these processes can be feasible at the LHC. (orig.)
