Moments of parton distributions functions of the pion from lattice QCD using gradient flow

Anthony Francis, Patrick Fritzsch, Rohith Karur +7

We present a nonperturbative determination of the pion valence parton distribution function (PDF) moment ratios $⟨ x^{n - 1} ⟩ / ⟨ x ⟩$ …

Gradient flow for parton distribution functions: first application to the pion

Anthony Francis, Patrick Fritzsch, Robert V. Harlander +9

Parton distribution functions (PDFs) are central to precision QCD phenomenology. Their Mellin moments can be computed on the lattice, but direct determinations using local operator…

Signs of Non-Monotonic Finite-Volume Corrections to $g_{A}$

Zack B. Hall, Dimitra A. Pefkou, Aaron S. Meyer +10

We study finite-volume (FV) corrections to determinations of $g_{A}$ via lattice quantum chromodynamics (QCD) using analytic results and numerical analysis. We observe that $S U (2)$ H…
