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 $z$ between quark/gluon bilinears for controlla…

Massless fermions in uniform flux background on $T^{2} \times R$ : Vacuum quantum numbers from single-particle filled modes using lattice regulator

Nikhil Karthik, Rajamani Narayanan, Ray Romero

The quantum numbers of monopoles in $R^{3}$ in the presence of massless fermions have been analyzed using a uniform flux background in $S^{2} \times R$ coupled to fermions. An analogous…

Lattice QCD Calculation of $x$ -dependent Meson Distribution Amplitudes at Physical Pion Mass with Threshold Logarithm Resummation

Ian Cloet, Xiang Gao, Swagato Mukherjee +5

We present a lattice quantum chromodynamics (QCD) calculation of the $x$ -dependent pion and kaon distribution amplitudes (DA) in the framework of large momentum effective theory. T…
