Transport coeffcients from pQCD to the Hadron resonance gas at finite BSQ densities

We calculate the shear viscosity, η, in two limits: perturbative QCD and an excluded-volume hadron resonance gas (HRG), at finite BSQ densities. Using an interpolation framework, we connect these regimes. In addition, we present results for (almost) next-to-leading order weak-coupling shear viscosity for QCD at finite μB, and discuss the convergence of the perturbative series

Abstract

We calculate the shear viscosity, η, in two limits: perturbative QCD and an excluded-volume hadron resonance gas (HRG), at finite BSQ densities. Using an interpolation framework, we connect these regimes. In addition, we present results for (almost) next-to-leading order weak-coupling shear viscosity for QCD at finite μB, and discuss the convergence of the perturbative series
