Description
Experiments at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) probe the properties of nuclear matter at extremely high temperatures and densities. Hadronic observables in the final stage of the heavy ion collision can be described well by fluid dynamics or blast wave parameterizations. We improve existing blast wave models by adding shear viscous corrections to the particle distributions in the Navier-Stokes approximation. The specific shear viscosity of a hadron gas at the freeze-out temperature is a new parameter in this model. We extract the blast wave parameters with viscous corrections from experimental data which leads to constraints on the specific shear viscosity.
Summary
we provide a blast wave model with viscous corrections and extract the blast wave parameters using this model.
