Abstract

We study bottomonium hadroproduction in proton-antiproton collisions at the Fermilab Tevatron in the framework of the quasi-multi-Regge kinematics approach and the factorization formalism of nonrelativistic QCD at leading order in the strong-coupling constant \ensuremathα_s and the relative velocity v of the bound quarks. The transverse-momentum distributions of prompt \ensuremathΥ(nS)-meson production measured at the Tevatron are fitted to obtain the nonperturbative long-distance matrix elements for different choices of unintegrated gluon distribution functions of the proton.
