夸克-胶子等离子体的硬QCD探针

Hard QCD probes to quark-gluon plasma

Carlos A. Salgado

摘要:

在对撞机能量下的重离子实验中,QCD完全未被探索的区域,主要是高密度/温度效应。成功的RHIC计划显示了频谱的高横向动量部分对于所创建介质的特性的表征是多么相关。它还指出,原子核的波函数在动量x的一小部分时具有有趣的性质,可能由饱和色场支配。在这两个领域中,即将到来的LHC计划将提供一个相空间,相对于RHIC研究的相空间扩大了几个数量级。我将回顾重离子碰撞中硬探测器的现状以及对大型强子对撞机的期望。

英文摘要:

Completely unexplored regimes of QCD, dominated by high-density/temperature effects, are available in heavy ion experiments at collider energies. The successful RHIC program shows how relevant the high transverse momentum part of the spectrum is for the characterization of the properties of the created medium. It points, as well, to interesting properties of the nuclear wave function at small fraction of momentum x, probably dominated by saturated color fields. In both domains, the imminent LHC program will provide a phase space enlarged by orders of magnitude with respect to those studied at RHIC. I will review the present status of hard probes in heavy ion collisions as well as the expectations for the LHC.
