论文摘要
我们提出了一个基于$ U（1）_ {T3R} $扩展标准模型的模型。该模型解决了第三代和前两代费米子之间的质量层次结构。 $ u（1）_ {t3r} $在$ \ sim 1-10 $ gev时自发折断。该模型包含一个子GEV暗物质候选者和两个子GEV光标量表和矢量介体。该模型解释了热暗物质的丰度，MUON G-2和$ r_ {K^{（\ ast）}} $异常的测量。该模型可以在LHC，FASER，暗物质实验和各种基于光束降低的中微子设施，例如Coherent，CCM，Microboone，SBND，Icarus，Dune等。
We present a model based on a $U(1)_{T3R}$ extension of the Standard Model. The model addresses the mass hierarchy between the third generation and the first two generation fermions. $U(1)_{T3R}$ is spontaneously broken at $\sim 1-10$ GeV. The model contains a sub-GeV dark matter candidate and two sub-GeV light scalar and vector mediators. The model explains the thermal dark matter abundance, measurements of the muon g-2 and $R_{K^{(\ast)}}$ anomalies. The model can be probed at the LHC, FASER, dark matter experiments and various beam-dump based neutrino facilities, e.g., COHERENT, CCM, MicroBooNE, SBND, ICARUS, DUNE etc.
