基础复合材料2 HDM:SU(N),具有4种风味

Fundamental Composite 2HDM: SU(N) with 4 flavours

Teng Ma, Giacomo Cacciapaglia

摘要:

我们提出了一个新的复合Higgs模型,该模型基于规范SU(N)群,在基本表象中有4个Dirac费米子。在低能量下,该模型具有整体对称性SU(4)$\times$ SU(4)破缺为对角SU(4),在陪集中包含2个Higgs双峰。我们详细研究了通过4-费米子相互作用产生的顶质量,以及真空排列的问题。特别是,我们证明了,不失一般性,真空总是可以与一个偶极子对齐。在某些条件下,在顶部的前Yukawas,第二个双重态,加上额外的三重态,是稳定的,因此可以发挥暗物质的作用。因此,该模型可以作为复合惰性-2HDM模型的一个例子。

英文摘要:

We present a new model of composite Higgs based on a gauged SU(N) group with 4 Dirac fermions in the fundamental representation. At low energy, the model has a global symmetry SU(4)$\times$SU(4) broken to the diagonal SU(4), containing 2 Higgs doublets in the coset. We study in detail the generation of the top mass via 4-fermion interactions, and the issue of the vacuum alignment. In particular, we prove that, without loss of generality, the vacuum can always be aligned with one doublet. Under certain conditions on the top pre-Yukawas, the second doublet, together with the additional triplets, is stable and can thus play the role of Dark Matter. This model can therefore be an example of composite inert-2HDM model.
