Central exclusive χc production
(2010) 13th International Conference on Elastic and Diffractive Scattering, EDS 2009 p.206-211- 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.
