Following the nonrelativistic QCD factorization scheme, by taking the latest available measurements of χbJ(3P) into consideration, we present an updated study on the yield and polarization of ϒ(1S, 2S, 3S) hadroproduction, and the fractions of χbJ(mP) feed-down in ϒ(nS) production at QCD next-to-leading order.

8. Energy dependence of direct-quarkonium production in pp collisions from fixed-target to LHC energies: complete one-loop analysis / Feng, Yu ; Lansberg, Jean-Philippe ; Wang, Jian-Xiong
We compute the energy dependence of the PT -integrated cross section of directly produced quarkonia in pp collisions at next-to-leading order (NLO), namely up to αS3 , within nonrelativistic QCD (NRQCD), treating the PT - integrated and the PT - differential cross sections as two different observables.
