Quark Wigner Distributions and Orbital Angular Momentum in Light-front Dressed Quark Model (1403.6233v3)
Published 25 Mar 2014 in hep-ph
Abstract: We calculate the Wigner functions for a quark target dressed with a gluon. These give a combined position and momentum space information of the quark distributions and are related to both generalized parton distributions (GPDs) and transverse momentum dependent parton distributions (TMDs). We calculate and compare the different definitions of quark orbital angular momentum in this model. We compare our results with other model calculations.
