Abstract

In applying large-momentum effective theory, renormalization of the Euclidean correlators in lattice regularization is a challenge due to linear divergences in the self-energy of Wilson lines. Based on lattice QCD matrix elements of the quasi-PDF operator at lattice spacing a = 0.03 fm similar to 0.12 fm with clover and overlap valence quarks on staggered and domain-wall sea, we design a strategy ...
