在LHC上寻找额外Higgs玻色子

Extra Higgs boson searches at the LHC

Junquan Tao

AI总结:

本文汇总ATLAS和CMS利用13 TeV质子-质子碰撞数据寻找额外Higgs玻色子的最新结果,涵盖直接产生及经由标准模型Higgs或重共振衰变的渠道,尚未发现新物理直接证据,但部分末态存在轻微超出。

摘要:

许多有趣的标准模型之外的模型都预言了额外的Higgs玻色子,在LHC上已经开展了大量针对这些额外Higgs玻色子的寻找。本文介绍了在LHC上寻找额外Higgs玻色子的若干精选最新结果。这些额外Higgs玻色子既可能直接由部分子相互作用产生,也可能来自已观测到的标准模型Higgs玻色子或某种新的更重共振态的衰变。这些寻找使用了LHC在质心系能量√s=13 TeV下提供、并由ATLAS和CMS探测器记录的质子-质子碰撞数据。目前尚未观测到新物理的直接证据。在部分末态中观测到若干轻微的超出。需要更多数据才能断定这些超出的本质。

英文摘要:

Many searches for additional Higgs bosons, which are predicted by a lot of interesting models beyond the standard model, have been performed at the LHC. Some selected latest results of the searches for extra Higgs bosons at the LHC are presented. These additional Higgs bosons could be produced either directly from the parton interactions or from the decays of the observed standard model Higgs boson or a new heavier resonance. The searches used the data from proton-proton collisions delivered by the LHC at a centre-of-mass energy of $\sqrt{s}=13~\TeV$ and recorded with the ATLAS and CMS detectors. No direct evidence of new physics has been observed yet. Several mild excesses were observed in some final states. More data is needed to conclude on the nature of these excesses.
