$\sqrt{s_{NN}}=200$ GeV上AuAu,CuCu和pp碰撞的非光子电子-强子方位角关联

Non-photonic electron-hadron azimuthal correlation for AuAu, CuCu and pp collisions at $\sqrt{s_{NN}}=200$ GeV

摘要:

本文给出了在$\sqrt{s_{NN}}=200$ GeV下AuAu、CuCu和pp中非光子电子与强子之间方位角关联的初步STAR结果。比较这些碰撞系统的e-h相关性可以研究重夸克喷流与介质相互作用对系统尺寸的依赖性。我们还报告了从pp碰撞中测量的相关性中提取的非光子电子的相对魅力和底部贡献。我们的结果,当结合$R_{AA}$测量的非光子电子,约束的魅力和底部的能量损失在稠密介质。

英文摘要:

We present preliminary STAR results of azimuthal correlations between non-photonic electrons and hadrons in AuAu, CuCu and pp at $\sqrt{s_{NN}}=200$ GeV. Comparison of the e-h correlations from these colliding systems allows one to study the system-size dependence of heavy quark jet-medium interactions. We also report on the relative charm and bottom contributions to non-photonic electrons extracted from correlations measured in pp collisions. Our results, when combined with $R_{AA}$ measurements of non-photonic electrons, constrain the charm and bottom energy loss in the dense medium.
