Abstract:
The present scenarios on the Universe and its evolution after Big Bang suggest that at a few microseconds a quark-gluon plasma has been formed. Recent experimental results obtained in nucleus-nucleus collisions at RHIC-BNL energies indicated that such a form of nuclear matter has been observed. Using different models for Universe evolution, experimental results, simulations, and calculations for the space-time characteristics of the particle emitting source formed in relativistic nuclear collisions we establish a "microscopic Hubble constant" and a posssible "temporal Hubble scale" for relativistic nuclear collisions, Our results are in agreement with other attempts.
