Description
We present the first lattice QCD determination of the gluon helicity parton distribution function (PDF) toward ruling out the negative gluon polarization in the nucleon within the mid to large momentum fraction region. Additionally, we highlight the potential synergy between lattice QCD and generative machine learning applications, offering an avenue to explore the diverse systematic uncertainties linked to determining both unpolarized and polarized gluon distributions in the nucleon. We briefly outline preliminary findings concerning the gluon distribution in the pion using large-$N_c$ lattice gauge theory calculations and explore its potential implications.
