摘要：

我提出了一个新的扩展粒子物理学的标准模型，它引入了一个黑暗的部门与$SU(2)_{D}\otimes U(1)_{D'}$对称除了SM部门。模型中的新粒子都存在于暗区。暗规范对称性破缺将带来超越SM的丰富物理学。微小的中微子质量是通过狄拉克类型的跷跷板机制产生的。暴胀子衰变不仅可以提供宇宙的暴胀和再加热，还可以导致重子的不对称性和冷暗物质的不对称性。简而言之，该模型提供了中微子质量、重子不对称性、不对称CDM和暴胀的统一，并能解释它们的共同起源。最后，在不久的将来的实验中，很有可能检验模型的预测和探测暗区物理。

英文摘要：

I suggest a new extension of the standard model of particle physics, which introduces a dark sector with the $SU(2)_{D}\otimes U(1)_{D'}$ symmetry besides the SM sector. The new particles of the model all inhabit in the dark sector. The dark gauge symmetry breaking will bring about fruitful physics beyond the SM. The tiny neutrino mass is generated through the Dirac-type seesaw mechanism. The inflaton decay can not only provide the universe inflation and reheating, but also lead to the baryon asymmetry and the asymmetric cold dark matter. In short, the model provides an unification of the neutrino mass, the baryon asymmetry, the asymmetric CDM and the inflation, and it can account for their common origin. Finally, it is very possible to test the model predictions and probe the dark sector physics in near future experiments.
