# Perturbative Renormalization of quasi-PDFs

@inproceedings{Constantinou2017PerturbativeRO, title={Perturbative Renormalization of quasi-PDFs}, author={Martha Constantinou and H. Panagopoulos}, year={2017} }

In this paper we present results for the renormalization of gauge invariant nonlocal fermion operators which contain a Wilson line, to one-loop level in lattice perturbation theory. Our calculations have been performed for Wilson/clover fermions and a wide class of Symanzik improved gluon actions. The extended nature of such ‘long-link’ operators results in a nontrivial renormalization, including contributions which diverge linearly as well as logarithmically with the lattice spacing, along…
