Diffractive production of χc(0+,1 +,2+) mesons at LHC, Tevatron and RHIC

Abstract

We consider exclusive double diffractive production of scalar χc(0+), axial-vector χc(1+) and tensor χc(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 χc(0+), χc(1+) and χc(2+) including branching fraction for radiative J/Φ + γ decay channel. Corresponding experimental... (More)
