论文摘要
我们调查了在最小模型中统一通货膨胀和暗物质物理的可能性，该模型具有复杂的标量暗物质，并使用$ z_3 $对称性。黑暗的本地$ u（1）$对称性自发地破坏了黑暗希格斯机构的$ z_3 $对称性。与$ z_2 $奇偶校验的暗物质模型相比，暗物质立方体自我交互限制了与非最小耦合的通货膨胀，以超越纯净的暗物质方向，并在通货膨胀预测的环校正中起重要作用，并确定正确的暗元物质。考虑到$ 2 \ rightarrow 2 $，$ 3 \ rightarrow 2 $或禁止通道是暗物质的主要生产机制，我们显示了模型的可行参数空间，这些空间与理论和现象学约束一致。
We investigate the possibility of unifying the inflation and dark matter physics in the minimal model for a complex scalar dark matter with gauged $Z_3$ symmetry. The dark local $U(1)$ symmetry is broken spontaneously into the $Z_3$ symmetry by the dark Higgs mechanism. As compared to dark matter models with $Z_2$ parity, the dark matter cubic self-interaction restricts the inflation with non-minimal couplings to take place beyond the pure dark matter direction and plays an important role in the loop corrections for the inflationary predictions as well as determining the correct dark matter relic density. Considering either of $2\rightarrow 2$, $3\rightarrow 2$ or forbidden channels to be a dominant production mechanism for dark matter, we show the viable parameter space of the model that is consistent with the theoretical and phenomenological constraints combined from inflation and dark matter.
