Abstract

Quantum transport theory and disoriented chiral condensate (DCC) in the Nambu-Jona-Lasinio model are investigated. The kinetic equations are derived in covariant and equal-time formulations. It is found that DCC is closely connected with the fluctuation of quark spin density. For the longitudinally expanding system, which models a highenergy nucleus-nucleus collision, a DCC present initially is quickly dissolved due to the expansion and the collision processes. However, the quantum off-shell effect leads to a strong fluctuation of DCC.
