A Transport Equation for Quantum Fields with Continuous Mass Spectrum

Abstract

Within a relativistic real-time Green's function formalism, a quantum transport equation for the phase-space distribution function is derived without a quasi-particle approximation. Dissipation is due to a nonzero spectral width, and can be separated into time-local and memory effects.
