摘要:

高能重离子碰撞的主要目标之一是建立QCD相图和寻找可能的相边界。计划中的RHIC能量扫描计划将利用不同质心能量的重离子碰撞来探索这一令人兴奋的物理学课题。在$\sqrt{s_{NN}}$ = 9.2 GeV的Au+Au碰撞的第一次测试运行发生在2008年初。我们提出的结果,确定粒子比,方位角各向异性参数(V1和V2)和HBT在midrapidity使用的数据,从这次运行。这些结果进行了比较,在AGS,SPS和RHIC的较低和较高的质心能量的数据。这些新的数据证明了STAR探测器探索QCD相图的能力。

英文摘要:

One of the primary goals of high-energy heavy-ion collisions is to establish the QCD phase diagram and search for possible phase boundaries. The planned RHIC energy scan program will explore this exciting physics topic using heavy-ion collisions at various center of mass energies. The first test run with Au+Au collisions at $\sqrt{s_{NN}}$ = 9.2 GeV took place in early 2008. We present the results on identified particle ratios, azimuthal anisotropy parameters (v1 and v2) and HBT at midrapidity using data from this run. These results are compared to data for both lower and higher center of mass energies at the AGS, SPS and RHIC. These new data demonstrate the capabilities of the STAR detector for exploring the QCD phase diagram.
