A Guide to Light-Cone PDFs from Lattice QCD: An Overview of Approaches, Techniques, and Results

Figure 17

Left: Equation (81) for two lattice spacings with solid (open) symbols corresponding to the finer (coarser) lattice spacing. The curve shows the three-loop perturbative result, shifted vertically by to match the unsmeared data on the finer lattice spacing. Right: for , using unsmeared gauge links, for a range of and ; the horizontal axis is . The green open squares/ blue filled diamonds/ orange filled triangles show results in RI-xMOM / ()/ (2GeV).
