重离子碰撞理论

Theory of Heavy-Ion Collisions

Thorsten Renk

摘要:

在高能核-核碰撞中,产生了由量子色动力学控制的热化、热和致密物质的瞬态。这种态的性质反映在集体介质的残余物即低横动量强子的产生,以及不属于热化介质的所谓探测物的变形,即在高横动量过程中产生的喷流或不参与强相互作用的轻子和光子。理论工作的目标是从这些观测量推导出QCD的热力学和集体性的性质。

英文摘要:

In high energy nucleus-nucleus collisions, a transient state of thermalized, hot and dense matter governed by Quantum Chromodynamics is produced. Properties of this state are reflected in the bulk low transverse momentum (P_T) hadron production which represent the remnant of the collective medium as well as in modifications of so-called probes which are not part of the thermalized medium, i.e. jets generated in high P_T processes or leptons and photons which do not participate in the strong interaction. Theory effords aim at deducing the properties of QCD thermodynamics and collectivity from such observables.
