Query: Isospin correlations in high-energy heavy-ion collisions   We study the posibility of large isospin fluctuations in high-energy
heavy-ion collisions by assuming that pions are produced semiclassically both
directly and in pairs through the isovector channel. 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. In terms of the
joint probability function $P_{II_{3}}(n_{0},n_{\_})$ for producing $n_{0}$
neutral and $n_{\_}$ negative pions from a definite isospin state $II_{3}$ of
the incoming leading-particle system we calculate the two pion correlation
parameters $f_{2,n_{\_}}^{0}$ and the average number of neutral pions $(< n_{0}
>_{n_{\_}})$ as a function of negative pions $(n_{\_})$ produced. We show that
only direct production of pions without isovector pairs leads to large isospin
fluctuations.
