Title: SPIN EFFECTS IN DIFFRACTIVE CHARMONIA PRODUCTION
Abstract:We consider exclusive double diffractive production of polarised axial-vector χ c (1 + ) and tensor χ c (2 + ) charmonia in proton-(anti)proton collisions at Tevatron energy. The corresponding amplitu...We consider exclusive double diffractive production of polarised axial-vector χ c (1 + ) and tensor χ 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.Read More
