AI总结:

本文是面向非专业人士的喷注修正理论综述,梳理传统与现代可观测量的研究现状,展望未来理论、唯象学进展与新数据结合对定量确定介质性质的作用。

摘要:

本篇综述面向非专业人士与初学者,梳理了致密物质中喷注修正理论的研究现状。我们首先概述无需借助事件产生器即可计算的“传统”可观测量,包括单强子与双强子抑制、核修正因子随反应平面的变化等。所有这些测量结果既用于佐证喷注修正所需的基础物理图像,也用于验证最终得到的喷注输运系数取值。随后,我们综述了随着全喷注重建能力发展而出现的更现代的可观测量,以及其中面临的挑战。最后,我们预览了该领域即将到来的理论进展,并展望这些进展、唯象学改进与即将获取的数据三者的结合,将如何让我们能够定量确定影响硬喷注修正的介质性质。

英文摘要:

In this review, intended for non-specialists and beginners, we recount the current status of the theory of jet modification in dense matter. We commence with an outline of the "traditional" observables which may be calculated without recourse to event generators. These include single and double hadron suppression, nuclear modification factor versus reaction plane etc. All of these measurements are used to justify both the required underlying physical picture of jet modification as well as the final obtained values of jet transport coefficients. This is followed by a review of the more modern observables which have arisen with the ability to reconstruct full jets, and the challenges faced therein. This is followed by a preview of upcoming theoretical developments in the field and an outlook on how the interface between these developments, phenomenological improvements, and upcoming data will allow us to quantitatively determine properties of the medium which effect the modification of hard jets.
