STAR p+p和Au+Au碰撞的J/psi产生和关联

J/psi production and correlation in p+p and Au+Au collisions at STAR

Zebo Tang

摘要:

本文给出了200 GeV p+p和Au+Au碰撞中J/psi pT谱的测量结果,pT范围为3-10 GeV/c。高pT J/psi的核修正因子在外围Au+Au碰撞中与无抑制一致,在中心Au+Au碰撞中显著小于1。在20- 60%Au +Au碰撞中,当pT < 10 GeV/c时,J/psi椭圆流与无流是一致的。

英文摘要:

The results on J/psi pT spectra in 200 GeV p+p and Au+Au collisions at STAR with pT in the range of 3-10 GeV/c are presented. Nuclear modification factor of high-pT J/psi is found to be consistent with no suppression in peripheral Au+Au collisions and significantly smaller than unity in central Au+Au collisions. The J/psi elliptic flow is measured to be consistent with no flow at pT < 10 GeV/c in 20-60% Au+Au collisions.
