Phys. Rev. C 63, 061901(R) (2001) [5 pages]Probing chiral dynamics by charged-pion correlations
The environment generated in the midrapidity region of a high-energy nuclear collision endows the pionic degrees of freedom with a time-dependent effective mass. Its specific evolution provides a mechanism for the production of back-to-back charge-conjugate pairs of soft pions which may present an observable signal of the nonequilibrium dynamics of the chiral order parameter. © 2001 The American Physical Society URL:
