    "abstract": "We derive the effective coarse-grained field equation for the scalar\ncondensate of the linear sigma model in a simple and straightforward manner\nusing linear response theory. The dissipative coefficient is calculated at tree\nlevel on the basis of the physical processes of sigma-meson decay and of\nthermal sigma-mesons and pions knocking sigma-mesons out of the condensate. The\nfield equation is solved for hot matter undergoing either one or three\ndimensional expansion and cooling in the aftermath of a high energy nuclear\ncollision. The results show that the time constant for returning the scalar\ncondensate to thermal equilibrium is of order 2 fm/c.",
