In the past decade, the Large Hadron Collider (LHC) has probed a higher energy scale than ever before. Most models of physics beyond the standard model (BSM) predict the production of new heavy particles; the LHC results have excluded lower masses of such particles. This makes the high-mass regions especially interesting for current and future searches. In most BSM scenarios of interest, the new heavy resonances decay to standard model particles. In a subset of these models, the new particles have large couplings to the top quark, the W and Z bosons, or the Higgs boson. The top quark and W, Z, and Higgs bosons often decay to quarks, giving rise to jets of particles with substructure; event selection based on substructure is used to suppress standard model backgrounds. This review covers the key concepts in experimental searches based on the jet substructure and discusses recent results from the ATLAS and CMS experiments.

搜索具有 Substructure 的重共振


在过去的十年中，大型强子对撞机 （LHC） 探测到的能量尺度比以往任何时候都高。标准模型 （BSM） 之外的大多数物理模型都预测了新的重粒子的产生;LHC 结果排除了此类粒子的较低质量。这使得高质量区域对于当前和未来的搜索特别有趣。在大多数感兴趣的 BSM 场景中，新的重共振会衰减为标准模型粒子。在这些模型的子集中，新粒子与顶夸克、W 和 Z 玻色子或希格斯玻色子有很大的耦合。顶夸克和 W、Z 和希格斯玻色子经常衰变为夸克，从而产生具有子结构的粒子射流;基于子结构的事件选择用于抑制标准模型背景。本综述涵盖了基于 jet 子结构的实验搜索中的关键概念，并讨论了 ATLAS 和 CMS 实验的最新结果。
