Propagation Speeds of Relativistic Conformal Particles from a Generalized Relaxation Time Approximation

The propagation speeds of excitations are a crucial input in the modeling of interacting systems of particles. In this paper, we assume the microscopic physics is described by a kinetic theory for massless particles, which is approximated by a generalized relaxation time approximation (RTA) where th...
