Description
Wigner distributions give a three dimensional picture of the quarks and gluons in a nucleon, and are related to the generalzed transverse momentum dependent parton distributions (GTMDs). These also give the orbital angular momentum and the spin-orbit correlations of the quarks and gluons. We calculate the Wigner distributions and GTMDs for a simple spin 1/2 composite state, namely a quark dressed with a gluon, for different target and quark polarization including transverse polarization. We also discuss the gluon Wigner distributions in this model for different polarizations.
