Sažetak
He posibility of large isospin fluctuations in high-energy heavy ion-collisions is studied within the framework of the nonlinear sigma-model with quark degrees of freedom. The multipion exchange potential between quarks is derived. The leading-particle effect and the factorization property of the scattering amplitude in the impact parameter space are used to define the classical pion field. The joint probability function for producing n0 neutral and n- negative pions is studied. It is shown that emission of isovector clusters of pions with the global conservation of isospin strongly suppresses the isospin fluctuation.
