Query: 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 $R^{-1/2}/2$. 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.
