论文摘要
中微子质量的起源是一个谜,它的性质也是如此,即中微子是狄拉克还是主要的颗粒。最重要的是,MUON和电子异常磁矩(AMM)的大偏差的提示是超出标准模型的物理学的有力证据。在这项工作中,将这些难题拼凑在一起,我们提出了一类辐射迪拉克中微子质量模型,以调和$(g-2)_ {μ,e} $带有中微子振荡数据的异常。在此框架中,一组通用的新物理(NP)状态通过产生非零中微子质量的环,由于手性增强,对Lepton Amms提供了大量的NP贡献。此外,这项工作中研究的三个模型之一提供了一个由残留对称性自动稳定的暗物质候选者,其现象学无关紧要与上面提到的其他两个难题。最后,我们的详细数值分析揭示了这些谜团的成功解决,同时与所有山脉和宇宙学约束保持一致。
The origin of neutrino mass is a mystery, so is its nature, namely, whether neutrinos are Dirac or Majorana particles. On top of that, hints of large deviations of the muon and the electron anomalous magnetic moments (AMMs) are strong evidence for physics beyond the Standard Model. In this work, piecing these puzzles together, we propose a class of radiative Dirac neutrino mass models to reconcile $(g-2)_{μ,e}$ anomalies with neutrino oscillation data. In this framework, a common set of new physics (NP) states run through the loops that generate non-zero neutrino mass and, due to chiral enhancement, provide substantial NP contributions to lepton AMMs. In addition, one of the three models studied in this work offers a Dark Matter candidate automatically stabilized by the residual symmetry, whose phenomenology is non-trivially connected to the other two puzzles mentioned above. Finally, our detailed numerical analysis reveals a successful resolution to these mysteries while being consistent with all colliders and cosmological constraints.
