Abstract

The discovery of the Higgs boson has led to new possible signatures for heavy resonance searches at the LHC. Since then, search channels including at least one Higgs boson plus another particle have formed an important part of the program of new physics searches. In this report, the status of these searches by the CMS Collaboration is reviewed. Searches are discussed for resonances decaying to two Higgs bosons, a Higgs and a vector boson, or a Higgs boson and another new resonance. All analyses use proton–proton collision data collected at s=13TeV in the years 2016–2018. A combination of the results of these searches is presented together with constraints on different beyond-the-standard model scenarios, including scenarios with extended Higgs sectors, heavy vector bosons and extra dimensions. Studies are shown for the first time by CMS on the validity of the narrow-width approximation in searches for the resonant production of a pair of Higgs bosons. The potential for a discovery at the High Luminosity LHC is also discussed.
通过重共振衰变寻找希格斯玻色子的产生
希格斯玻色子的发现为大型强子对撞机的重共振搜索带来了新的可能特征。从那时起,包括至少一个希格斯玻色子和另一个粒子的搜索通道已经成为新物理搜索计划的重要组成部分。在本报告中,CMS协作审查了这些搜索的状态。讨论了共振衰减到两个希格斯玻色子,一个希格斯玻色子和一个矢量玻色子,或者一个希格斯玻色子和另一个新的共振的搜索。所有分析都使用了2016-2018年在s=13TeV下收集的质子-质子碰撞数据。这些搜索结果的组合与不同的超出标准模型场景的约束一起呈现,包括扩展希格斯扇区,重矢量玻色子和额外维度的场景。CMS首次证明了窄宽度近似在寻找一对希格斯玻色子共振产生中的有效性。高亮度大型强子对撞机的潜在发现也进行了讨论。

期刊介绍: Physics Reports keeps the active physicist up-to-date on developments in a wide range of topics by publishing timely reviews which are more extensive than just literature surveys but normally less than a full monograph. Each report deals with one specific subject and is generally published in a separate volume. These reviews are specialist in nature but contain enough introductory material to make the main points intelligible to a non-specialist. The reader will not only be able to distinguish important developments and trends in physics but will also find a sufficient number of references to the original literature.
