Fluctuations and correlations in pion system with fixed isospin
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 obs...

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. |
