Abstract
The PHENIX experiment at the relativistic heavy ion collider (RHIC) has measured transverse energy and charged particle multiplicity at midrapidity in collisions at center-of-mass energies , and as a function of centrality. The presented results are compared to measurements from other RHIC experiments and experiments at lower energies. The dependence of and per pair of participants is consistent with logarithmic scaling for the most central events. The centrality dependence of and is similar at all measured incident energies. At RHIC energies, the ratio of transverse energy per charged particle was found to be independent of centrality and growing slowly with . A survey of comparisons between the data and available theoretical models is also presented.
