Central exclusive production of polarised charmonia

We consider exclusive double diffractive production of polarised axial-vector χc(1+) and tensor χc(2+) charmonia in proton-(anti)proton collisions at Tevatron energy. The corresponding amplitudes for these processes are derived within the kt-factorisation approach. Contributions from different polarisation states of axial-vector and tensor charmonia are quantified. Corresponding experimental consequences are discussed.
