Title: Hadroproduction of heavy quarkonia at the LHC

The production of heavy quarkonia at the LHC is considered. It is shown that, in the case of the inclusive production of χ{sub cJ}P-wave charmonia, existing experimental data can be described upon taking into account next-to-leading corrections, a dominant contribution coming from color-singlet states. For the case of B{sub c}-meson production, it is shown that, at experimentally accessible values of the transverse momentum, power-law corrections to the cross section make a significant contribution, with the result that the cross-section ratio σ(B{sub c})/σ(B) develops a p{sub T} dependence not observed in the fragmentation regime. The case of double vector-charmonium production is also considered.
