Improved quasi parton distribution through Wilson line renormalization

Chen, Jiunn-Wei ; Ji, Xiangdong ; Zhang, Jian-Hui



Abstract

Recent developments showed that hadron light-cone parton distributions could be directly extracted from spacelike correlators, known as quasi parton distributions, in the large hadron momentum limit. Unlike the normal light-cone parton distribution, a quasi parton distribution contains ultraviolet (UV) power divergence associated with the Wilson line self energy. We show that to all orders in the ...
