在Higgs门框架中探测来自Higgs奇异衰变的多μ子喷流

Detecting multimuon jets from the Higgs exotic decays in the Higgs portal framework

Jung Chang, Kingman Cheung, Shih-Chieh Hsu, Chih-Ting Lu

摘要:

μ子喷流($μ$ -jet)是一种非常特殊的特征,它由质量约为$\mathcal{O}$(1 GeV)的快速移动轻粒子衰变产生的准直μ子簇组成。我们将利用这一特性从希格斯玻色子的罕见衰变中寻找非常轻的粒子。对于这种小角距的μ子,这可能来自一个长寿命的粒子,ATLAS和CMS都可以有位移顶点重建能力。我们使用两个简单的模型的希格斯门型探索事件拓扑的可能性,两个$2μ$ -喷气机,一个$2μ$ -喷气机$\&$一个$4μ$ -喷气机,和两个$4μ$ -喷气机在LHC-14的最终状态。我们还总结了这些模型的现有限制。

英文摘要:

A muon jet ($μ$-jet) is a very special feature that consists of a cluster of collimated muons from the decay of a fast moving light particle of mass about $\mathcal{O}$(1 GeV). We will use this feature to search for very light particles from rare decays of the Higgs boson. For such a small angular separation of muons which might come from a long-lived particle, both ATLAS and CMS could have the displaced-vertexing-reconstruction capability. We use two simple models of the Higgs-portal type to explore the possibilities of event topologies with two $2μ$-jets, one $2μ$-jet $\&$ one $4μ$-jet, and two $4μ$-jets in the final state at LHC-14. We also summarize existing constraints on these models.
