Abstract

The early stage of high multiplicity nuclear collisions is represented by a nearly quarkless, hot, deconfined pure gluon plasma. These new scenario should be characterized by a suppression of high pT photons and dileptons as well as by reduced baryon to meson ratios. We present the numerical results for central Pb+Pb collisions at the LHC energies by using the ideal Bjorken hydrodynamics with time-dependent quark fugacity. It is shown that about 25 % of final total entropy is generated during the hydrodynamic evolution of chemically undersaturated quark-gluon plasma. (
