STAR在sqrt(s_NN)= 4.5 GeV时Au + Au固定靶碰撞的结果

STAR Results from Au + Au Fixed-Target Collisions at sqrt(s_NN) = 4.5 GeV

Kathryn Meehan

摘要:

我们目前的结果,从星的第一个专用的固定目标运行在2015年进行的金+金碰撞sqrt(s_NN)= 4.5 GeV。质子和强子的定向流、已识别强子的椭圆流、HBT半径以及π、K^0_s和λ谱与AGS的先前结果进行了比较。这些结果表明,STAR具有良好的事件重建和粒子识别能力的固定目标配置。这些结果对未来的STAR固定目标运行的影响进行了讨论。

英文摘要:

We present results from STAR's first dedicated fixed-target run conducted in 2015 with Au + Au collisions at sqrt(s_NN) = 4.5 GeV. Directed flow of protons and lambdas, elliptic flow of identified hadrons, HBT radii, as well as pion, K^0_s, and Lambda spectra are compared with previous results from the AGS. These results demonstrate that STAR has good event reconstruction and particle identification capabilities in the fixed-target configuration. The implications of these results on future STAR fixed-target runs are discussed.
