Transport coefficients for multi-component gas of hadrons using Chapman Enskog method
The transport coefficients of a multicomponent hadronic gas at zero and nonzero baryon chemical potential are calculated using the Chapman-Enskog method. The calculations are done within the framework of an S-matrix based interacting hadron resonance gas model. In this model, the phase shifts and cr...

description | The transport coefficients of a multicomponent hadronic gas at zero and nonzero baryon chemical potential are calculated using the Chapman-Enskog method. The calculations are done within the framework of an S-matrix based interacting hadron resonance gas model. In this model, the phase shifts and cross sections are calculated using K-matrix formalism and where required, by parametrizing the experimental phase shifts. Using the energy dependence of the cross section, we find the temperature dependence of various transport coefficients such as shear viscosity, bulk viscosity, heat conductivity, and diffusion coefficient. We finally compare our results regarding various transport coefficients with previous results in the literature. |
