论文摘要
在这项工作中，我们首次提出和探索了通常在许多不同类别的多higgs模型中发现的重型中性标量的新对撞机签名。该签名在大型强子对撞机（LHC）测量的背景下特别相关，是基于拓扑结构，其中有两个带电的瘦素和四个由第一代和第二代夸克产生的喷气机。作为多基格斯模型的重要基准场景，我们专注于最近提出的Branco-Grimus-Lavoura（BGL）类型模型，增强了Abelian U（1）风味对称性，并具有右手中微子的附加领域。我们讨论该模型中标量场的运动学如何用于有效地将信号与主要背景区分开，并探索即将到来的LHC运行中新的重型标量的发现潜力。该方法可以用于分析LHC在LHC和未来的任何多HIGGS模型中重量标量生产的统计显着性。
In this work, we propose and explore for the first time a new collider signature of heavy neutral scalars typically found in many distinct classes of multi-Higgs models. This signature, particular relevant in the context of the Large Hadron Collider (LHC) measurements, is based on a topology with two charged leptons and four jets arising from first and second generation quarks. As an important benchmark scenario of the multi-Higgs models, we focus on a recently proposed Branco-Grimus-Lavoura (BGL) type model enhanced with an abelian U(1) flavour symmetry and featuring an additional sector of right-handed neutrinos. We discuss how kinematics of the scalar fields in this model can be used to efficiently separate the signal from the dominant backgrounds and explore the discovery potential of the new heavy scalars in the forthcoming LHC runs. The proposed method can be applied for analysis of statistical significance of heavy scalars' production at the LHC and future colliders in any multi-Higgs model.
