　　Abstract:

　　The quasi-probabilistic Wigner distributions are the quantum mechanical analog of the classical phase-space distributions. We investigate quark Wigner distributions for a quark state dressed with a gluon, which can be thought of as a simple composite and relativistic spin-1/2 state with a gluonic degree of freedom.We also examine the connection between the Wigner distribution and the orbital angular momentum (OAM) of quarks.
