Energy Dependence of Hadronic Observables in Central Pb+Pb Reactions at the CERN SPS

Abstract

In this contribution the energy dependence of various hadronic observables as measured by the NA49 experiment in the beam energy range between 20 and 158 AGeV is presented. These include mt and rapidity distributions, particle ratio fluctuations, as well as HBT radii. The data are put in the context of results from the AGS and RHIC.
