Abstract: | We consider a gas of interacting relativistic effective mesons (qualitatively, like those produced in a heavy-ion collision),
regarded as an out-of-equilibrium statistical system. We suppose large occupation numbers, temperature somewhat below typical
critical temperatures and the quasi-classical regime. At some initial time t0, let the gas be in a nonequilibrium state, with spatial inhomogeneities. The time evolution of the gas for t > t
0 is studied by a moment method, and appropriate long-time approximations, which could yield the approach to global thermal
equilibrium, are discussed. |
