Fluctuations and correlations in pion system with fixed isospin

Viktor Begun, M. I. Gorenstein, O. A. Mogilevsky

Abstract

The statistical system of π 0 , π + and π − mesons with zero total isospin is studied. For neutral pions there is the enhancement of the fluctuations, whereas for charged pions the isospin conservation suppresses fluctuations. The correlations between the numbers of charged and neutral pions are observed for finite systems.
