Gluon Wigner distributions under transverse polarization at non-zero skewness
Abstract
Abstract We investigate the Wigner distributions of gluons at non-zero skewness using light-front wave functions within the dressed quark model, where the target state is a quark dressed with a gluon in the leading-order Fock space expansion. The analyses focus on the configurations wherein the gluon and/or the target are transversely polarized. Subsequently, we derive analytical expressions for the Wigner distributions in the boost-invariant longitudinal space ( σ ) for transversely polarized configurations. Resultantly, a diffraction-like oscillatory pattern is yielded in σ -space, which is analogous to that reported previously for unpolarized and longitudinally polarized gluons.
