论文摘要
我们提出了简单的Scoto-SeeSaw模型，以解释具有自发CP违规的暗物质和中微子质量。这是通过单个水平$ \ MATHCAL {Z} _8 $离散对称性来实现的，破坏了残留的$ \ Mathcal {Z} _2 $子组负责稳定暗物质。 CP通过标量单元的复杂真空期望值自发折断，从而诱导了麻质的CP侵略效应。我们发现，施加的$ \ Mathcal {Z} _8 $对称性将Dirac CP相位的值和最轻的中微子质量推向已经进行的实验已经探索的范围，因此可以通过宇宙学观察结果和中性beta beta beta deble Beta deble deas day实验来将正常排序的中微子质量缠绕。
We propose simple scoto-seesaw models to account for dark matter and neutrino masses with spontaneous CP violation. This is achieved with a single horizontal $\mathcal{Z}_8$ discrete symmetry, broken to a residual $\mathcal{Z}_2$ subgroup responsible for stabilizing dark matter. CP is broken spontaneously via the complex vacuum expectation value of a scalar singlet, inducing leptonic CP-violating effects. We find that the imposed $\mathcal{Z}_8$ symmetry pushes the values of the Dirac CP phase and the lightest neutrino mass to ranges already probed by ongoing experiments, so that normal-ordered neutrino masses can be cornered by cosmological observations and neutrinoless double beta decay experiments.
