Polarized and unpolarized gluon PDFs: generative machine learning applications for lattice QCD matrix elements at short distance and large momentum
Talal Ahmed Chowdhury, Taku Izubuchi, Methun Kamruzzaman +6
Lattice quantum chromodynamics (QCD) calculations share a defining challenge by requiring a small finite range of spatial separation between quark/gluon bilinears for controlla…

Nonlocal chiral anomaly and generalized parton distributions
Shohini Bhattacharya, Yoshitaka Hatta, Jakob Schoenleber
We discuss the nonlocal generalization of the QCD chiral anomaly along the light-cone and derive relations between twist-two, twist-three and twist-four generalized parton distribu…

Breakdown of collinear factorization in the exclusive photoproduction of a pair with large invariant mass
Saad Nabeebaccus, Jakob Schoenleber, Lech Szymanowski +1
We study the exclusive photoproduction of a pair with large invariant mass , which is sensitive to the exchange of either two quarks or two gluons in th…
