Transverse momentum broadening at NLO and QCD evolution of
arXiv:1407.8506 · doi:10.1016/j.nuclphysa.2014.10.030
Abstract
Within the framework of a high-twist approach, we show the first complete next-to-leading order calculation of transverse momentum broadening in semi-inclusive deeply inelastic scattering and Drell-Yan dilepton production in collisions. We demonstrate at one-loop level how QCD factorization holds for multiple scattering in nuclear medium, and the university of the associated quark-gluon correlation function. Our calculation also identifies QCD evolution equation for the quark-gluon correlation function, which determines the QCD factorization scale and energy dependence of jet transport parameter .
