Related power-law growth of particle multiplicities near midrapidity in central Au+Au collisions and in p(p)–p collisions Original Research Article

A simple power-law growth of charged-particle multiplicities near midrapidity in central Au+Au collisions at View the MathML source and 130 GeV, recently measured at RHIC, is derived. We give predictions for the central particle densities up to View the MathML source GeV. A strong growth of the Au+Au densities above those for View the MathML source–p collisions is predicted.
