✦ Synopsis

Transport equations for quark matter are derived in the mean field approximation for the Nambu Jona-Lasinio Lagrangian. Emphasis is put on the chiral limit (zero current quark mass) and the consequences of the chiral symmetry are investigated in detail. Our approach is based on the spinor decomposition of the Wigner function. Kinetic equations for the quark densities and for the evolution of the spin are derived. We find that the latter is constrained by the requirement of the axial current conservation.
