  2. Heavy quarkonium production at high transverse momentum( p_T p T )in hadronic collisions is explored in the QCD factorization approach. Wefind that the leading power in the 1/p_T 1 / p T expansion is responsible for high p_T p T regime, while the next-to-leading power contribution is necessary forthe low p_T p T region. We present the first numerical analysis of the scale evolutionof coupled twist-2 and twist-4 fragmentation functions (FFs) for heavyquarkonium production and demonstrate that the QCD factorizationapproach is capable of describing the p_T p T spectrum of hadronic J/\psi J / ψ production at the LHC.

    We report the current understanding of heavy quarkonium production at high transverse momentum ( p T ) in hadronic collisions in terms of QCD factorization. In this presentation, we highlight the role of subleading power corrections to heavy quarkonium production, which are essential to describe the p T spectrum of quarkonium at a relatively lower p T . We also introduce prescription to match QCD factorization to fixed-order NRQCD factorization calculations for quarkonium production at low p T .
