Sažetak
The posibility of large charge and isospin fluctuations in high-energy heavy ion-collisions are studied within the framework of the quantum nonlinear sigma-model coupled to quark degrees of freedom. The multipion exchange potential between two quarks is derived which is different from one-gluon exchange potential. It is shown that the soft chiral pion bremsstralung leads to anomalously large fluctuations in the ratio of neutral to charged pions, predicted by the formation of a disoriented chiral condensate(DCC). The factorization property of the scattering amplitude in the impact parameter space of the leading two-nucleon system is used to study semiclassical production of pions in the central region.
