Abstract: (arXiv)
Extracting parton structure from lattice quantum chromodynamics (QCD) calculations requires studying the coordinate scale z3z_3 dependence of the matrix elements of bilocal operators. The most significant contribution comes from the z3z_3 dependence induced by ultraviolet (UV) renormalization of the Wilson line. We demonstrate that the next-to-leading order perturbative calculations of the renormalization factor can describe, to a few percent accuracy, the logarithm of the lattice QCD rest frame matrix elements with separations up to distances of 0.6~fm on multiple lattice spacings. The residual discrepancies can be modeled by a leading effect from the structure of the nucleon.
