论文摘要

通过Katrin实验,将绝对中微子的质量规模降低到宇宙学上的偏爱值。我们表明,该测量值在Scotogenic模型中提供了标准模型与黑暗扇区之间的缺失联系,在经济上,抑制中微子质量是通过其唯一的间接耦合到Higgs场来解释的。我们确定电子中微子质量与标量耦合$λ_5$之间的线性关系与深中性标量质量分裂为$λ_5= 3.1 \ times10^{ - 9} \ m_ {ν_e}/$ ev。然后,这种关系引起了DM和新标量质量及其Yukawa耦合之间的相关性。随后,Katrin和未来的Lepton侵犯实验可以探测Fermion DM参数空间,而与中微子质量层次结构和CP相关。

With the KATRIN experiment, the determination of the absolute neutrino mass scale down to cosmologically favored values has come into reach. We show that this measurement provides the missing link between the Standard Model and the dark sector in scotogenic models, where the suppression of the neutrino masses is economically explained by their only indirect coupling to the Higgs field. We determine the linear relation between the electron neutrino mass and the scalar coupling $λ_5$ associated with the dark neutral scalar mass splitting to be $λ_5=3.1\times10^{-9}\ m_{ν_e}/$eV. This relation then induces correlations among the DM and new scalar masses and their Yukawa couplings. Together, KATRIN and future lepton flavor violation experiments can then probe the fermion DM parameter space, irrespective of the neutrino mass hierarchy and CP phase.
