Diffractive production of chi(c)(0+,1+,2+) mesons at LHC, Tevatron and RHIC
Abstract
We consider exclusive double diffractive production of scalar c(0+), axial-vector c(1+) and tensor c(2+) charmonia in proton-(anti)proton collisions at different energies. The corresponding amplitudes for these processes are derived within the kt-factorisation approach and the corresponding cross section is calculated with different unintegrated gluon distribution functions (UGDFs) known from the literature. We compare exclusive production of all charmonium states c(0+), c(1+) and c(2+) including branching fraction for radiative J/ + γ decay channel. Corresponding experimental consequences are discussed.
