Anomalous net-baryon-rapidity spectra at RHIC

Abstract

Net-baryon rapidity distributions in central Au+Au collisions at 200 GeV per nucleon are shown to consist of three components. The nonequilibrium contributions are accounted for in a Relativistic Diffusion Model. Near midrapidity, a third fraction containing approximately 22 protons reaches local statistical equilibrium in a discontinuous transition. It may be associated with a deconfinement of the participant partons and thus, serve as a signature for Quark-Gluon Matter formation.
