New Method of Modelling Dissipative Hydrodynamics
arXiv:0812.4164
Abstract
We propose to model the dissipative hydrodynamics used in description of the multiparticle production processes (-hydrodynamics) by a special kind of the perfect nonextensive fluid (-fluid) where denotes the nonextensivity parameter appearing in the nonextensive Tsallis statistics. The advantage of -hydrodynamics lies in its formal simplicity in comparison to the -hydrodynamics. We argue that parameter describes summarily (at least to some extent) all dynamical effects behind the viscous behavior of the hadronic fluid.
