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

Figure 31

“Ratio-renormalized” matrix elements of the operator defining gluon quasi-PDFs in the study of [229]. Nucleon momenta are 0.46 and 0.92 GeV. Valence pion mass of 340 MeV (left) and 678 MeV (right). Also plotted are inverse Fourier transforms of two phenomenological fits to experimental data: CT14 [210] and PDF4LHC15 [24]. Source: [229] (arXiv), reprinted with permission by the Authors.
