Abstract

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. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 72 is September 2022.

用子结构搜索重共振

在过去的十年里，大型强子对撞机（LHC）探测到了比以往任何时候都更高的能量尺度。大多数超出标准模型（BSM）的物理模型预测新的重粒子的产生；LHC的结果已经排除了这种粒子的较低质量。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，新的重共振衰减为标准模型粒子。在这些模型的一个子集中，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，产生具有亚结构的粒子喷流；采用基于子结构的事件选择方法来抑制标准模型背景。这篇综述涵盖了基于射流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。《核与粒子科学年度评论》第72卷预计最终在线出版日期为2022年9月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

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.
