论文摘要
已知在超相关的重型离子碰撞中产生的热和密集培养基的存在可以改变Parton淋浴的演变。对产生的射流活性的几个观察结果表明，可以被认为是从“真空”（质子 - 普罗顿）参考的中型射流的显着修改。这些修饰（通常称为喷射淬灭效应）是Parton淋浴与产生的快速发展的夸克 - 胶状等离子体（QGP）的多种相互作用的结果。最近的努力试图评估喷气淬火效应的时间依赖性，特别关注晚期或早期动态。在这次演讲中，我们展示了一种新颖的工具，可以通过应用喷气重凝集技术来潜在地评估QGP的全日制演变。结果可以将新颖的见解带入QGP扩展中，并阐明了如何以一致的方式重新和类似真空的和中等样的排放量重新融合到单个Parton淋浴演化方程中。
The presence of a hot and dense medium, produced in ultra-relativistic heavy-ion collisions, is known to modify the parton shower evolution. Several observations of the resulting intra-jet activity show significant modifications of what can be considered as a medium-modified jet from a "vacuum" (proton-proton) reference. These modifications, generically known as jet quenching effects, are the result of the multiple interactions of the parton shower with the produced fast-evolving quark-gluon plasma (QGP). Recent efforts have tried to assess the time dependence of jet quenching effects, with particular focus on late or early dynamics. In this talk, we show a novel tool that can potentially evaluate the full-time evolution of the QGP by applying jet reclustering techniques. The result can bring novel insights into the QGP expansion as well as shed some light on how to re-sum, in a consistent way, vacuum-like and medium-like emissions into a single parton shower evolution equation.
