Abstract [en]

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