论文摘要
我们建议使用隐藏的$ \ mathrm {u}（1）$量规对称性的伪 - nambu-goldstone暗物质的紫外线完成模型。与以前的研究相比，这种设置更简单，引入了更少的相互作用。紫外线量表高度抑制了核子的暗物质散射，直接检测约束很容易逃避。隐藏的$ \ mathrm {u}（1）$与$ \ mathrm {u}（1）_ \ mathrm {y} $ gauge fields之间的动力学混合将导致暗物质衰减。我们发现，暗物质寿命上的电流绑定意味着紫外线量表应高于$ 10^{10}〜\ mathrm {gev} $。还研究了125个GEV Higgs测量，暗物质遗物密度和间接检测暗物质歼灭的现象学约束。
We propose an ultraviolet completion model for pseudo-Nambu-Goldstone dark matter with a hidden $\mathrm{U}(1)$ gauge symmetry. Compared to previous studies, this setup is simpler, introducing less interactions. Dark matter scattering off nucleons is highly suppressed by the ultraviolet scale and direct detection constraints can be easily evaded. The kinetic mixing between the hidden $\mathrm{U}(1)$ and the $\mathrm{U}(1)_\mathrm{Y}$ gauge fields would lead to dark matter decays. We find that the current bound on the dark matter lifetime implies that the ultraviolet scale should be higher than $10^{10}~\mathrm{GeV}$. The phenomenological constraints from the 125 GeV Higgs measurements, the dark matter relic density, and indirect detection of dark matter annihilation are also investigated.
