论文摘要
我们从隐藏的SU（2）_D量规对称性上提出了矢量暗物质模型。引入标量septulet，以自发打破SU（2）_D对称性。 Septuplet还起着标准模型和黑暗扇区之间门户的作用。我们发现，有两种不同的真空配置对应于四分之一耦合$λ_3$的符号，该符号为仪表玻色子产生不同的质谱。对于$λ_3<0 $，仪表玻色子的质量正在分裂，而对于$λ_3\ geq0 $，质量是退化的。我们还研究了耦合的RG演变，并发现扰动性和真空稳定性可以在参数空间上设置一个严格的结合。对于现象学方面，我们考虑了实验性约束，包括暗物质直接检测，间接检测，遗物密度和希格斯耦合测量值。我们发现，有参数空间来自所有约束，并且可以在未来的暗物质直接和间接检测实验中进行测试。
We propose a vector dark matter model from a hidden SU(2)_D gauge symmetry at TeV scale. A scalar septuplet is introduced to break the SU(2)_D symmetry spontaneously. The septuplet also play the role of a portal between the standard model and the dark sector. We find that there are two different vacuum configurations corresponding to the sign of the quartic coupling $λ_3$, which yields different mass spectrum for the gauge bosons. For a $λ_3<0$, the masses of gauge bosons are splitting, while for a $λ_3\geq0$, the masses are degenerate. We also study the RG evolutions of the couplings, and find that the perturbativity and vacuum stability can set a stringent bound on the parameter space. For the phenomenological aspect, we consider the experimental constraints including dark matter direct detection, indirect detection, relic density, and Higgs couplings measurements. We find that there are parameter space survive from all the constraints, and they can be tested in future dark matter direct and indirect detection experiments.
