Cutting rules on a cylinder: a simplified diagrammatic approach to quantum kinetic theory
Abstract Nonequilibrium quantum field theory is often used to derive an approximation for the evolution of number densities and asymmetries in astroparticle models when a more precise treatment of quantum thermal effects is required. This work presents an alternative framework using the zero-tempera...
