Abstract:We calculate inclusive cross section for f 2 (1270) tensor meson production via color singlet gluon-gluon fusion in the k t -factorization approach with unintegrated gluon distribution functions (UGDFs). The process may be potentially interesting in the context of searches for saturation effects. The energy-momentum tensor, equivalent to helicity-2 coupling, and helicity-0 coupling are used for the g * g * → f 2 (1270) vertex. Two somewhat different parametrizations of helicity-2 and helicity-0 tensorial struc… Show more
