Sommario:
- 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 $μ_B$, and discuss the convergence of the perturbative series.
