Central Exclusive \chi_c Production

The amplitudes of the central exclusive production of c mesons are calculated using different unintegrated gluon distribution functions (UGDFs).

description The amplitudes of the central exclusive production of c 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 c(0+), c(1+) and c(2+) including branching fraction for radiative J/ + decay channel. Kinematical enhancement of the maximal helicity amplitudes is shown.
