核碰撞中轻子对的产生:过去、现在和未来

Lepton-pair production in nuclear collisions - past, present, future

H. J. Specht

摘要:

本文从70年代pp碰撞的根源开始,以RHIC和LHC对撞机的观点为基础,简要回顾了超相对论核碰撞中轻子对产生的关键结果。的存在是由最近的精度结果NA60在欧洲核子研究中心SPS,最终在第一次测量中的ρ谱函数和相关的热辐射的横向流动。在rho以上的流动似乎被切断,这很可能是核碰撞中部分子起源的热辐射的第一个直接暗示。在理论发展的主要里程碑也包括在内。

英文摘要:

The key results on lepton-pair production in ultra-relativistic nuclear collisions are shortly reviewed, starting at the roots of pp collisions in the seventies, and ending at the perspectives of the colliders RHIC and LHC. The presence is dominated by the recent precision results from NA60 at the CERN SPS, culminating in the first measurement of the in-medium rho spectral function and the transverse flow of the associated thermal radiation. The seeming cut-off of the flow above the rho may well be the first direct hint for thermal radiation of partonic origin in nuclear collisions. The major milestones in the theoretical developments are also covered.
