Initial State of Disoriented Chiral Condensate Formation
  It is unlikely to reach at high temperatures the state which is used as the starting point of DCC formation in the quenched approximation. The chiral symmetry is restored in the linear sigma model by Goldstone modes (pions), because such isospin-p-wave states carry more entropy. In this paper we estimate this effect of isospin-angular motion in the mean field approximation assuming equipartition of the energy.
