Abstract

The study of high-energy heavy-ion collisions at the Relativistic Heavy Ion Collider and the Large Hadron Collider has evolved from a qualitative understanding to the precise extraction of the properties of the quantum chromodynamics medium at extremely high temperatures. 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 regarding 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 toward precise extraction of the QGP properties. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 73 is September 2023.

相对论重离子碰撞中的介质响应和射流-强子关联

在相对论重离子对撞机和大型强子对撞机上对高能重离子碰撞的研究已经从定性认识发展到精确提取极高温度下量子色动力学介质的性质。射流猝灭为高能碰撞中产生的夸克-胶子等离子体(QGP)的输运特性提供了独特的见解。除了射流的介质修饰外，射流诱导的介质激励是射流- qgp相互作用的另一个重要方面，对于理解射流的软成分是必不可少的。我们回顾了最近关于介质对射流能量损失的响应的理论和现象学发展，包括描述射流能量沉积的热化和传播的弱耦合和强耦合方法的概述，介质响应对射流观测值的影响，以及其在射流-强子相关性中的独特特征的探索。射流诱导介质激励被证明是探测射流介质动力学的重要组成部分，也是精确提取QGP特性的关键步骤。预计《核与粒子科学年度评论》第73卷的最终在线出版日期为2023年9月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
