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

Key Points

• This research aims to calculate and connect shear viscosity in perturbative QCD and a hadron resonance gas at finite baryon strangeness quantum (BSQ) densities.
• Calculated shear viscosity in perturbative QCD and excluded-volume HRG limits.
• Utilized interpolation framework to connect different regimes.
• Examined next-to-leading order weak-coupling shear viscosity for QCD at finite baryon chemical potential.
• Shear viscosity was successfully computed in both perturbative and HRG scenarios.
• Next-to-leading order results were presented, indicating convergence of the perturbative series.
• Demonstrated the impact of finite BSQ densities on shear viscosity calculations.
