I suggest a left-right mirror symmetric particle model as the natural and aes- thetic extension of the SM. As the left-right mirror symmetry breaking, the tiny neutrino mass is generated by the radiative mechanism, the baryon asymmetry through the lepto- genesis arises from the characteristic decay of the TeV-scale mirror charged lepton, and a KeV-mass sterile Dirac fermion eventually becomes the CDM. The model can completely account for the common origin of the neutrino mass, the baryon asymmetry and the dark matter, moreover, profoundly uncover the internal connections among them. Finally, I discuss several feasible approaches to test the model predictions and probe the new physics by near future experiments.

左右镜像对称模型：中微子质量、重子不对称和暗物质的共同起源

我建议使用左右镜像对称粒子模型作为 SM 的自然和美学延伸。随着左右镜像对称性的破坏，微小的中微子质量由辐射机制产生，通过轻质发生的重子不对称性产生于 TeV 级镜像带电轻子的特征衰变，以及 KeV 质量的不育狄拉克费米子最终成为 CDM。该模型可以完全解释中微子质量、重子不对称性和暗物质的共同起源，并深刻揭示了它们之间的内在联系。最后，我讨论了几种可行的方法来测试模型预测并通过近期的实验探索新物理。
