Abstract
We study a Centauro-type phenomenon 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. We show that the Centauro-type effect is strongly suppressed if a large number of pions are produced in isovector pairs. Our conclusion is supported through the calculation of two pion correlation parameters, ${\mathit{f}}_{2}^{0\mathrm{\ensuremath{-}}}$ and ${\mathit{f}}_{2}^{00}$, as well as ${\mathit{f}}_{2,}$${\mathit{n}}_{\mathrm{\ensuremath{-}}}^{0}$ and the average number of neutral pions (〈${\mathit{n}}_{0}$${\mathrm{〉}}_{\mathit{n}\mathrm{\ensuremath{-}}}$) a a function of negative pions (${\mathit{n}}_{\mathrm{\ensuremath{-}}}$) produced.
