Content
Recently, methods that allow for the computation of parton distribution functions in lattice QCD have been proposed. In particular, it has been argued that time-local, and spatially non-local Euclidean matrix elements can be used as probes of hadronic structure and, in certain limits, light-cone parton distribution functions can be obtained. However, approaching these limits presents both numerical and theoretical challenges that need to be addressed. In this talk I will discuss aspects of non-perturbative calculations of parton distribution functions and will present numerical results for the relevant non-local matrix elements that utilize gradient flow to control ultraviolet divergences.
