Central exclusive χc production

Abstract

The amplitudes of the central exclusive production of χc mesons are calculated using different unintegrated gluon distribution functions (UGDFs). The procedure of generalisation of UGDF for non-forward case by saturation of positivity constraints is suggested. We compare exclusive production of all charmonium states χc(0+), χc(1+) and χc(2 +) including branching fraction for radiative J/ψ+γ decay channel. Kinematical enhancement of the maximal helicity amplitudes is shown.
