从RHIC束流能量扫描确定强子产生

Identified Hadron Production from the RHIC Beam Energy Scan

Lokesh Kumar

摘要:

RHIC目前的焦点是研究QCD相图--温度($T$)与重子化学势($μ_{B}$)。STAR实验收集了2010年$\sqrt{s_{NN}}=$ 7.7 GeV、11.5 GeV和39 GeV的Au+Au碰撞数据。我们目前midrapidity的快度密度,平均横向质量,和粒子比确定强子从STAR实验的结果。碰撞动力学研究的化学和动力学的冻结条件的框架。

英文摘要:

A current focus at RHIC is the Beam Energy Scan to study the QCD phase diagram -- temperature ($T$) vs. baryon chemical potential ($μ_{B}$). The STAR experiment has collected data for Au+Au collisions at $\sqrt{s_{NN}}=$ 7.7 GeV, 11.5 GeV, and 39 GeV in the year 2010. We present midrapidity results on rapidity density, average transverse mass, and particle ratios for identified hadrons from the STAR experiment. Collision dynamics are studied in the framework of chemical and kinetic freeze-out conditions.
