Nucleon thermal width owing to pion-baryon loops and its contributions to shear viscosity
Nucleon thermal width owing to pion-baryon loops and its contributions to shear viscosity
In the real-time thermal field theory, the standard expression of shear viscosity for the nucleonic constituents is derived from the two point function of nucleonic viscous stress tensors at finite temperature and density. The finite thermal width or Landau damping is traditionally included in the nucleon propagators. This thermal width …
