摘要:

在重离子碰撞中的喷流能量损失,如由高$p_T$强子的核修饰因子$R_{AA}$的传统可观察性量化的,提供了在重离子碰撞中产生的热介质的高度信息化的“成像”。现在有全面的可用数据集,从平均抑制到方位各向异性,从轻到重,从RHIC 200 GeV到LHC 2.76TeV以及5.02TeV碰撞。这样一个全面的数据的统一描述提出了一个严格的审查任何可行的模型射流淬火现象。在这篇文章中,我们报告了这样一个系统的和成功的测试CUJET 3,喷气能量损失模拟框架建立在一个非微扰微观模型的热介质作为半夸克胶子等离子体(sQGMP),它集成了两个基本要素的限制,即Polyakov环抑制夸克/胶子和紧急磁单极子。

英文摘要:

Jet energy loss in heavy ion collisions, as quantified by the traditional observable of high $p_T$ hadron's nuclear modification factor $R_{AA}$, provides highly informative "imaging" of the hot medium created in heavy ion collisions. There are now comprehensive sets of available data, from average suppression to azimuthal anisotropy, from light to heavy flavors, from RHIC 200GeV to LHC 2.76TeV as well as 5.02TeV collisions. A unified description of such comprehensive data presents a stringent vetting of any viable model for jet quenching phenomenology. In this contribution we report such a systematic and successful test of CUJET3, a jet energy loss simulation framework built upon a nonperturbative microscopic model for the hot medium as a semi-quark-gluon-monopole plasma (sQGMP) which integrates two essential elements of confinement, i.e. the Polyakov-loop suppression of quarks/gluons and emergent magnetic monopoles.
