论文摘要
在大型强子对撞机（LHC）中检测单个希格斯玻色子已允许一个人探测其中的某些特性，包括Yukawa和量规耦合。但是，为了探测希格斯的潜力，必须依靠新的生产机制，例如希格斯对生产。在本文中，我们表明，这样的频道也对所谓的“ Flavon”字段（$ H_F $）的生产和衰减敏感，这是一种新的标量状态，该状态在试图解释标准模型（SM）fermion质量的层次结构的模型中产生。我们的分析还集中在涉及Flavon颗粒的其他衰减通道上，特别是Flavon对一对$ Z $ Bosons（$ H_F \ to Z Z $）的衰减，以及同时产生的顶级夸克和Charm Quark（$ h_f \ to tc $），在最终州具有一个或多个Leptons。特别是，我们表明，使用3000 fb $^{ - 1} $在LHC的14 TEV（运行3阶段）的累计数据中，可以通过这些频道通过这些频道来探索重量$ M_ {H_F} \ simeq 2M_T $的重量$ h_f} \ simeq 2m_t $的重量$ h_f} \ simeq 2m_t $。
The detection of a single Higgs boson at the Large Hadron Collider (LHC) has allowed one to probe some properties of it, including the Yukawa and gauge couplings. However, in order to probe the Higgs potential, one has to rely on new production mechanisms, such as Higgs pair production. In this paper, we show that such a channel is also sensitive to the production and decay of a so-called `Flavon' field ($H_F$), a new scalar state that arises in models that attempt to explain the hierarchy of the Standard Model (SM) fermion masses. Our analysis also focuses on the other decay channels involving the Flavon particle, specifically the decay of the Flavon to a pair of $Z$ bosons ($H_F \to Z Z$) and the concurrent production of a top quark and charm quark ($H_F\to tc$), having one or more leptons in the final states. In particular, we show that, with 3000 fb$^{-1}$ of accumulated data at 14 TeV (the Run 3 stage) of the LHC an heavy Flavon $H_F$ with mass $M_{H_F} \simeq 2m_t $ can be explored with $3σ-5σ$ significance through these channels.
