First results from Au+Au collisions at $\sqrt{(}{s}_{NN})$ = 9.2 GeV in STAR

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. 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 $\sqrt{s_{NN}}$ = 9.2 GeV took place in early 2008. The large acceptance STAR detector has collected few thousands 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 $v_1$ and $v_2$ 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.
