Disoriented Chiral Condensates and Quantum Mechanical Isospin Correlation

Classical considerations suggest that the probability distribution P (R), where R is the ratio of neutral pions to total pions emitted from a disoriented chiral condensate (which has been hypothesized to form in heavy ion reactions) is R \Gamma1=2 =2. Quantum mechanical isospin correlations between the condensate and the remainder of the system can alter this. Moments of the P(R) distribution can be expressed in terms of expectation values of (I 2 =N 2 ) m where I is the isospin carried by the condensate, N is the number of pions emitted and m is an arbitrary integer. We find that the probability distribution is very similar to the classical distribution for 0:1 ! R ! 0:9 unless the isospin carried by the condensate is very large. 1 Permanent address: Instituto de F'isica, Universidade de S~ao Paulo, 01498 - SP- Brazil. Recently, there has been considerable attention given to the possible formation of a disoriented chiral condensate (DØC) in high energy collisions of heavy i..
