Angular momentum (AM) contains explicit position vectors, and its definition depends on the choice of pivot. The corresponding internal AM operators defined relative to the relativistic centers of energy, mass, and spin, as well as their transverse spin sum rules, have been studied previously. We extend this discussion to spatial distributions in the nucleon. We derive the two-dimensional...

We report updates on tackling the systematics in the nucleon gluon parton distribution function (PDF) from Large-Momentum Effective Theory (LaMET). We compute use the self renormalization technique to compute gluon PDFs from data measured on HISQ ensembles generated by the MILC collaboration with $N_f = 2 + 1 + 1$, $a = 0.15, 0.12, 0.09$ fm, with valence pion masses around 310 and 690 MeV. We...

The deuteron, as the lightest nuclear bound state, provides a unique laboratory for investigating the transition from conventional nuclear degrees of freedom to quark-gluon dynamics in nuclei. In this work, we explore QCD effects in the deuteron beyond the traditional proton-neutron description by incorporating hidden-color configurations within a light-front framework. Using a...
