Abstract
Ultra-relativistic nucleus-nucleus collisions create a state of matter of high temperature and small baryo-chemical potential, which is similar to the thermodynamical conditions in the primordial universe. Recent analyses of Au+Au collisions at RHIC revealed the temperature, size and density of the system. Thus, a comparison to the primordial universe can be attempted. In particular, two observables shall be investigated, namely (1) the temperature at baryon freeze-out (about t=10 fm/c in the + collision) and (2) the matter density at the partonic stage (t>1 fm/c).
