Life time of resonances in transport simulations

Abstract

We calculate the life time of a resonance in our recently developed framework for a test-particle description of transport processes for states with continuous mass spectra. The result differs from the expression commonly used in transport simulations but agrees with the one derived by Danielewicz and Pratt relating the life time to the scattering phase shift.
