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

Figure 18

Comparison of lattice estimates of the ETMC’s helicity PDF, properly renormalized (blue band) or renormalized using the local axial current renormalization factor (magenta band). For qualitative comparison, phenomenological PDFs (DSSV08 [206] and JAM15 [208]) are also plotted. Source: [151], reprinted with permission by the Authors (article available under CC BY).
