Description
I will discuss the impact of QCD corrections on the P_T differential cross section for quarkonium production in pp collisions at RHIC, Tevatron and LHC energies, as well as the contributions from charm-gluon fusion. I will present comparisons between the predictions of the Color Singlet Model up to alpha_s^5 with the first LHC data both for J/psi and Upsilon. I will also show predictions for the polarisation to be compared with the forthcoming LHC results. Finally, I will motivate the introduction of new observables meant to better discriminate between the different mechanisms at work in quarkonium production at the LHC.
