在RHIC重离子碰撞中用半相干双光子过程产生软$e^+e^-$对

Production of soft $e^+e^-$ Pairs in Heavy Ion Collisions at RHIC by Semi-coherent Two Photon Processes

Pilar Staig, Edward Shuryak

摘要:

我们计算了双光子产生过程对$e^+e^-$谱的贡献,并与RHIC PHENIX探测器的实验数据进行了比较。我们研究了“半相干”运动学的贡献,其中一个光子相对较硬,由参与的质子非相干发射,而另一个光子可以足够软,可以在相干域中。

英文摘要:

We calculate the contribution of the two photon production process into $e^+e^-$ spectra, and compare the results with experimental data from the PHENIX detector at RHIC. We study the contribution given by ``semi-coherent" kinematics, in which one photon is relatively hard and is incoherently emitted by participating protons, while another can be soft enough to be in a coherent domain.
