论文摘要
相对论重离子对撞机和大型强子对撞机处的高能重型离子碰撞已经从定性的理解中演变为在极高温度下量子染色体动力学培养基的性能的精确提取。喷气淬火提供了对这些充满活力碰撞中产生的夸克 - 格鲁隆等离子体（QGP）的运输特性的独特见解。除了媒介物的中等变化外，喷气引起的介质激发构成了JET-QGP相互作用的另一个关键方面，并且在理解喷气机的软组件方面是必不可少的。我们回顾了对喷气能量损失的中等反应的最新理论和现象学发展，包括概述弱和强烈耦合的方法，用于描述喷气机对能量沉积的热化和传播，培养基响应对喷气式可观察物的影响以及探索其在喷气式 - 哈德隆相关中的独特签名。喷射诱导的培养基激发被证明是探测喷气机内动力学的重要组成部分，并且是朝着精确提取QGP特性的关键步骤。
High-energy heavy-ion collisions at the Relativistic Heavy-Ion Collider and the Large Hadron Collider have evolved from qualitative understanding into precise extraction of the properties of the Quantum Chromodynamics medium at extremely high temperature. Jet quenching has offered unique insights into the transport properties of the Quark-Gluon Plasma (QGP) created in these energetic collisions. Apart from medium modification of jets, jet-induced medium excitation constitutes another crucial aspect of jet-QGP interaction, and is indispensable in understanding the soft components of jets. We review recent theoretical and phenomenological developments on medium response to jet energy loss, including an overview of both weakly and strongly coupled approaches for describing the thermalization and propagation of energy deposition from jets, effects of medium response on jet observables, and exploration of its unique signatures in jet-hadron correlations. Jet-induced medium excitation is shown to be an essential component in probing the in-medium dynamics of jets and a critical step towards precise extraction of the QGP properties.
