用轻子非零$θ_{13}$统一暗物质的味起源
Unifying the flavor origin of dark matter with leptonic nonzero $θ_{13}$
摘要：
我们提出了一个味对称的方法来统一暗物质（DM）的起源与非零的$θ_{13}$轻子部门。在这个框架中，打破$U(1)$味对称性的残余$Z_2$确保DM的稳定性，并引起对现有的基于$A_4$的三双峰中微子混合的修改，以获得所需的非零$\sin θ_{13}$。这导致在一系列的希格斯门户耦合的DM，可以潜在地访问在各种正在进行的和未来的直接和对撞机搜索实验。
英文摘要：
We propose a flavor symmetric approach to unify the origin of dark matter (DM) with the non-zero $θ_{13}$ in the lepton sector. In this framework, breaking of a $U(1)$ flavor symmetry to a remnant $Z_2$ ensures the stability of the DM and gives rise to a modification to the existing $A_4$-based tri-bimaximal neutrino mixing to attain the required non-zero $\sin θ_{13}$. This results in a range of Higgs portal coupling of the DM which can be potentially accessible at various ongoing and future direct and collider search experiments.
