Diffractive J/ψ photoproduction at largemomentum transfer in coherent hadron - hadroninteractions at CERN LHC

摘要

The vector meson production in coherent hadron-hadron interactions at LHC energies is addressed assuming that the color singlet t-channel exchange carries large momentum transfer. We consider the non-forward solution of the BFKL equation at high energy and large momentum transfer and estimate the rapidity distribution and total cross section for the process h_1 h_2→h_1J/ΨX, where h_i can be a proton or a nucleus. We predict large rates, which implies that the experimental identification could be feasible at the LHC.
