sqrt(s_NN)= 200 GeV Au+Au碰撞中直接光子产生的中心性依赖

Centrality Dependence of Direct Photon Production in sqrt(s_NN) = 200 GeV Au+Au Collisions

PHENIX Collaboration, S. S. Adler

摘要:

首次测量了sqrt(sNN)= 200GeV的Au+Au碰撞中的直接光子.直接的光子信号提取作为一个功能的金+金碰撞中心和比较NLO pQCD计算。直接光子产额示出的规模与核子核子碰撞的数量为所有的中心。

英文摘要:

The first measurement of direct photons in Au+Au collisions at sqrt(s_NN) = 200 GeV is presented. The direct photon signal is extracted as a function of the Au+Au collision centrality and compared to NLO pQCD calculations. The direct photon yield is shown to scale with the number of nucleon-nucleon collisions for all centralities.
