Аннотация:We discuss the spacetime structure for the decay of a bubble of hypothetical phase-disoriented chiral condensate (DCC). The evolution of the initial classical-field configuration corresponding to a DCC bubble has been studied both numerically and analytically. The decay of this initial configuration depends crucially on the self-interaction of pion fields. It has been shown that, in some cases, this self-interaction leads to the formation of a breather solution formed from pion fields and situated at the center of the initial DCC bubble. This breather appears to be a long-lived source of pion fields.
