论文摘要
我们探索了一个暗物质(DM)的模型,该模型可以解释MUON异常磁矩中报告的差异,并预测MUON的大型电偶极矩(EDM)。该模型包含一个DM费米和新标量,其与MUON的独家相互作用辐射产生了观察到的MUON质量。 DM直接和间接检测实验以及对撞机搜索的约束被安全逃避。具有观察到的DM丰度并解释Muon $ G-2 $异常的模型参数空间导致$d_μ\ simeq(4 $ - $ 5)\ times 10^{ - 22} \,e \,e \,{\ rm cm cm} $可以通过Projected Psi psi Mudem mudm mudm mudem验证。另一个可行的参数空间甚至达到了$d_μ= \ Mathcal {o}(10^{ - 21})\,e \,{\ rm cm} $,由正在进行的Fermilab Muon $ g-2 $实验和未来的J-Parc Muon $ g-2 $ g-2 $ g-2 $ g-2 $ g-2 $ g-2 $ g-2 $ g-2 $ g-2 $ g。
We explore a model of dark matter (DM) that can explain the reported discrepancy in the muon anomalous magnetic moment and predict a large electric dipole moment (EDM) of the muon. The model contains a DM fermion and new scalars whose exclusive interactions with the muon radiatively generate the observed muon mass. Constraints from DM direct and indirect detection experiments as well as collider searches are safely evaded. The model parameter space that gives the observed DM abundance and explains the muon $g-2$ anomaly leads to the muon EDM of $d_μ \simeq (4$-$5) \times 10^{-22} \, e \, {\rm cm}$ that can be probed by the projected PSI muEDM experiment. Another viable parameter space even achieves $d_μ = \mathcal{O}(10^{-21}) \, e \, {\rm cm}$ reachable by the ongoing Fermilab Muon $g-2$ experiment and the future J-PARC Muon $g-2$/EDM experiment.
