On the symmetries of the 1+1 dimensional relativistic fluid dynamics

Abstract

A very intuitive description of nucleus-nucleus collision phenomena is provided by the relativistic fluid dynamics. We consider a 1+1 dimensional relativistic imperfect fluid flow to approximate the high energy heavy ion collision. The article investigates the application of the continuous symmetry group on the relativistic fluid energy-momentum tensor conservation equations in the ultrarelativistic limit $\gamma \to \infty$.
