Summary

The quark-gluon plasma created in relativistic heavy ion collisions is described as a relativistic fluid, with a formidably large value of initial acceleration (10^30 g). We show that stress-energy tensor mean value have additional terms with respect to the ideal form which are quadratic in the acceleration and vorticity, of quantum origin and non-disspative, that is they do not increase entropy.
We show how to obtain these corrections by using general equilibrium form with acceleration and vorticity and performing a perturbative expansion from homogeneous global equilibrium. The thermodynamic coefficients relevant to these corrections can be expressed in terms of correlators of the stress-energy tensor operator and the generators of the Lorentz group.
