Abstract

One of the primary aims of heavy-ion collisions is to map the QCD phase diagram and search for different phases and phase boundaries. The RHIC Energy Scan Program was launched to address this goal by studying heavy-ion collisions at different center of mass energies. The first test run with Au+Au collisions at took place in early 2008. The large acceptance STAR detector has collected few thousand minimum bias collisions at this beam energy. We present the first results for identified particle yields and particle ratios. The results for the azimuthal anisotropy parameters v1 and v2 and those from pion interferometry measurements are also discussed in this paper. These results are compared to data from the SPS at similar beam energies.
