Title: "Lattice corrections to the quark quasidistribution at one-loop, and their unexpected results..."

Abstract: "The quark quasidistribution is a novel idea developed by X. Ji which fixes some of the hurdles associated with calculating parton distribution functions on the lattice.  In this presentation, I will cover a paper recently submitted by Carl Carlson and myself which details the lattice perturbation theory radiative corrections at one loop to the quark quasidistribution.  I will show how the infrared behavior of the corrections in Euclidean and Minkowski space are different.  In doing so, I will present features of momentum loop integrals and demonstrate why loop corrections from the lattice and Euclidean continuum do not correspond with their Minkowski brethren.  The role of the lattice spacing $a$ and of the Wilson parameter $r$ in these radiative corrections will also be examined."
