四回路辐射跷跷板模型

A four-loop Radiative Seesaw Model

Takaaki Nomura, Hiroshi Okada

摘要:

提出了一种新的辐射中微子模型,该模型具有全局隐$U(1)$对称性,中微子质量在四圈能级上诱导。然后讨论了μ子反常磁矩,解决了观测与标准模型预测之间的矛盾,并估算了模型中费米子或玻色子DM候选者的残余密度。我们还讨论了双光子共振$R$考虑过程$pp \to R \to γγ$作为我们的模型的一个可能的信号。

英文摘要:

We propose a new type of radiative neutrino model with global hidden $U(1)$ symmetry, in which neutrino masses are induced at the four loop level. Then we discuss the muon anomalous magnetic moment to solve the discrepancy between observation and the standard model prediction, and estimate the relic density of a fermion or boson DM candidate in the model. We also discuss the diphoton resonance $R$ by considering a process $pp \to R \to γγ$ as a possible signal of our model.
