论文摘要
我们提出了一个用于中微子质量的复合术模型,该模型是通过$ \ mathbb {z} _2 $ -ODD复合标量生成的。我们考虑了中微子(包括三个右撇子单元)和复合部门的三种不同方法:等等的四边形相互作用,基本的部分综合性和费米子部分综合性。在所有情况下,如果三个$ \ mathbb {z} _2 $ -ODD右手中微子在TEV和Planck尺度之间具有质量,则该模型都可以具有较大的耦合,并相对于各种实验约束。此外,最轻的$ \ mathbb {z} _2 $ -ODD复合标量可能会通过热冻结或作为不对称的遗物来扮演暗物质的角色。该机制可以在基于真空错位的多种模型中进行特征。为了进行具体性,我们在基于coset su(6)/sp(6)的复合材料两-higgs方案中证明了这一点。
We present a composite scotogenic model for neutrino masses, which are generated via loops of $\mathbb{Z}_2$-odd composite scalars. We consider three different approaches to the couplings of the neutrinos (including three right-handed singlets) and the composite sector: ETC-like four-fermion interactions, fundamental partial compositeness and fermion partial compositeness. In all cases, the model can feature sizeable couplings and remain viable with respect to various experimental constraints if the three $ \mathbb{Z}_2 $-odd right-handed neutrinos have masses between the TeV and the Planck scales. Additionally, the lightest $\mathbb{Z}_2$-odd composite scalar may play the role of Dark Matter, either via thermal freeze-out or as an asymmetric relic. This mechanism can be featured in a variety of models based on vacuum misalignment. For concreteness, we demonstrate it in a composite two-Higgs scheme based on the coset SU(6)/Sp(6).
