Description
We estimate dissipative properties viz: shear and bulk viscosities of hadronic matter using relativistic Boltzmann equation in relaxation time approximation within ambit of excluded volume
hadron resonance gas (EHRG) model. We find that at zero baryon chemical potential the shear
viscosity to entropy ratio (η/s) decreases with temperature and reaches very close to Kovtun-Son-Starinets (KSS) bound. At sufficiently large baryon chemical potential this ratio shows same behavior as a function of temperature but goes below KSS bound. We further find that along chemical freezout line η/s increases monotonically while the bulk viscosity to entropy ratio (ζ/s) decreases monotonically.
