Abstracts

EN

The first part of the beam energy scan (BES) program at RHIC was successfully completed in the years 2010 and 2011. First STAR results from particle yield measurements are in good agreement with previously published data from SPS and AGS experiments whereas other results like azimuthal HBT and K/π event-by-event fluctuations differ at some energies. In addition, new observations like the centrality dependence of chemical freeze-out parameters (T
ch and µB) or the smoothly increasing difference with decreasing energy in the elliptic flow v
2 between particles and corresponding anti-particles, are discussed.
