Dynamical gluon effects in proton transversity and off-forward parton distributions from a light-front Hamiltonian approach
Year: 2026
Type: preprint
Abstract: Building on proton light-front wave functions in the $|qqq\rangle$ and $|qqqg\rangle$ Fock sectors, obtained by diagonalizing the proton light-front Hamiltonian within the Basis Light-Front Quantization framework, we present a unified study of the proton's leading-twist transversity parton distribution functions, tensor charges, generalized tensor form factors, and chiral-odd skewed generalized parton distributions in the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi region. Our results compare reasonably with available phenomenological extractions and lattice-QCD simulations and follow similar qualitative trends.
