Non-Abelian chiral kinetic theory with self-consistent semiclassical expansion

Abstract

We derive the chiral kinetic theory in a non-Abelian gauge field using a self-consistent semiclassical expansion. Within this new expansion scheme, we disentangle the Wigner equations up to second order and demonstrate that they do not introduce additional constraint equations. By integrating the covariant chiral kinetic equations in eight-dimensional phase space, we obtain the corresponding equations in seven-dimensional phase space. This reduction facilitates numerical simulations and practical applications.
