Unveiling Skewness Dependence of Quark Wigner Distributions

We present a detailed investigation of the skewness dependence of quark Wigner distributions within the light-front dressed quark model. While previous studies have largely focused on the forward limit, we explore the impact of nonzero longitudinal momentum transfer ($\xi \neq 0$) on the full set of leading-twist quark Wigner distributions across various polarization configurations. We observe characteristic distortions in the spatial and momentum correlations with increasing skewness, including the emergence of dipole and quadrupole patterns, asymmetries, and localization effects. These features reflect spin-orbit correlations and quantum interference between light-front wave function components with differing orbital angular momentum.
