Topologically nontrivial time-dependent chiral condensates

Abstract

Topologically nontrivial time-dependent solutions of the classical nonlinear sigma model are studied as candidates of the disoriented chiral condensate (DCC) in 3+1 dimensions. Unlike the analytic solutions so far discussed, these solutions cannot be transformed into isospin-uniform ones by chiral rotations. If they are produced as DCC's, they can be detected by a distinct pattern in the angle-rapidity distribution of the neutral-to-chrged-pion ratio.
