QCD factorization for high heavy quarkonium production
Yan-Qing Ma, Jian-Wei Qiu, George Sterman +1
In this talk, we present the QCD factorization formula for heavy quarkonium production at large with factorized leading-power and next-to-leading power contributions in the $…
Fragmentation contributions to hadroproduction of prompt , , and states
Geoffrey T. Bodwin, Kuang-Ta Chao, Hee Sok Chung +3
We compute fragmentation corrections to hadroproduction of the quarkonium states , , and at leading power in , where is the charm-quark mass…
production and suppression in high energy proton-nucleus collisions
Yan-Qing Ma, Raju Venugopalan, Hong-Fei Zhang
We apply a Color Glass Condensate+Non-Relativistic QCD (CGC+NRQCD) framework to compute production in deuteron-nucleus collisions at RHIC and proton-nucleus collisions at the…
Fragmentation functions of polarized heavy quarkonium
Yan-Qing Ma, Jian-Wei Qiu, Hong Zhang
Study of the polarized heavy quarkonium production in recently proposed QCD factorization formalism requires knowledge of a large number of input fragmentation functions (FFs) from…
