Spin effects in diffractive charmonia production

High Energy Physics - Phenomenology 2011-03-02 v2

Abstract

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