Semiclassical Transport of Particles with Dynamical Spectral Functions *


The conventional transport of particles in the on-shell quasiparticle limit is extended to particles of finite life time by means of a spectral function A(X, P , M 2) for a particle moving in an area of complex self-energy Σ ret X = ReΣ ret X − iΓ X /2. Starting from the Kadanoff-Baym equations we derive in first order gradient expansion equations of motion… (More)
