Nonperturbative and spin effects in the central exclusive production of tensor ${\chi }_c(2^{+})$ meson

R. S. Pasechnik, A. Szczurek, O. V. Teryaev

We discuss central exclusive production (CEP) of the tensor ${\chi }_c(2^{+})$ meson in proton-(anti)proton collisions at Tevatron, RHIC and LHC energies. The amplitude for the process i…
