Bulk viscosity of nuclear matter with pions in the neutrino-trapped regime
Bulk viscosity of nuclear matter with pions in the neutrino-trapped regime
Recent work [Fore and Reddy, Phys. Rev. C 101, 035809 (2020)] has shown that a population of thermal pions could modify the equation of state (EoS) and transport properties of hot and dense neutron-rich matter and introduce new reaction pathways to change the proton fraction. In this article we study …
