Linearized Dissipative Relativistic Hydrodynamics

Leopoldo Garcia-Colin, Universidad Autonoma Metropolitana, Mexico
Building 6008 Conference Room

Relativistic hydrodynamic equations have become a rather fashionable subject to deal with the hot dense matter produced in the Relativistic Heavy Ion Collider (RHIC). In this talk I will show how such a set of equations may be derived from a suitable generalization of Classical Irreversible Thermodynamics. In their linearized form, these equations are free from instabilities and do not violate causality. These results are thus an improvement on the so-called "first order" theories and suggest that "second order" theories, although free from instabilities, may also be reconsidered since they contain adjustable parameters.
