摘要：
For cylindrical systems endowed with a longitudinal Bjorken scaling expansion, the semiclassical linear sigma model is employed to calculate the self-consistent dynamical evolution from the initially hot configuration towards the asymptotic state of freely moving pions. The correlation function for charge-conjugate soft pions with similar rapidities and transverse energies exhibits pronounced azimuthal anticorrelations that may be used to probe the nonequilibrium chiral relaxation dynamics.
