关于在LHC上寻找第二个标量偶线

On the search for a second scalar doublet at the LHC

Alejandro Celis

摘要:

出于自然风味守恒的原则,在大型强子对撞机上寻找第二个标量双峰的签名通常仅限于具有非常受限的汤川结构的模型。在这些模型中,由于基本的味道原理,标量耦合到费米子之间的强相关性是固定的,使得从这种分析中获得的结果高度依赖于模型。此外,来自风味实验的约束也有很大的不同模型内考虑。汤川对齐的假设提供了一个合适的框架,以执行更一般的分析125 GeV玻色子的数据和搜索额外的标量在大型强子对撞机,允许相当大的新的物理效应被观察到的标量部门,同时适应严格的限制,从味实验在同一时间。这种一般设置包括不同的模式与自然风味的保护作为特殊情况。

英文摘要:

Motivated by the principle of natural flavour conservation, searches for signatures of a second scalar doublet at the LHC are usually limited to models with a very restricted Yukawa structure. Strong correlations between the scalar couplings to fermions are fixed in these models due to the underlying flavour principle, making the results obtained from such analyses highly model dependent. Moreover, constraints derived from flavour experiments also vary radically within the different models considered. The hypothesis of Yukawa alignment provides a suitable framework to perform a more general analysis of 125 GeV boson data and searches for additional scalars at the LHC, allowing for sizable new physics effects to be observed in the scalar sector while accommodating the stringent limits from flavour experiments at the same time. This general setting includes the different models with natural flavour conservation as particular cases.
