Fluid dynamics of out of equilibrium boost invariant plasmas

Fluid dynamics of out of equilibrium boost invariant plasmas

By solving a simple kinetic equation, in the relaxation time approximation, and for a particular set of moments of the distribution function, we establish a set of equations which, on the one hand, capture exactly the dynamics of the kinetic equation, and, on the other hand, coincide with the hierar...
