AI 中文摘要
我们研究了一个具有世代分离的超荷与暗荷的框架。在扩展的超荷对称性\(U(1)_{Y1}\otimes U(1)_{Y2}\otimes U(1)_{Y3}\)自发破缺为标准模型的\(U(1)_Y\)后，带电费米子的层级质量和小的夸克混合可源于涉及超子场的高维算符。给出了不同超子扇区的几种实现方式以说明可能的味结构。聚焦于有四个超子的实现方式，通过跷跷板机制或暗跷跷板机制研究中微子质量产生，其可容纳微小的中微子质量和大的中微子混合。暗规范对称性\(U(1)_D\)的破缺留下一个残余的\(\mathbb{Z}_2\)对称性来稳定暗物质，允许费米子或标量候选者在与观测到的暗物质遗迹丰度和当前直接探测约束一致的可行的 TeV 尺度参数区域。
英文摘要
We study a framework with generation-separated hypercharges and dark charges. After the extended hypercharge symmetry $U(1)_{Y1}\otimes U(1)_{Y2}\otimes U(1)_{Y3}$ is spontaneously broken to the Standard Model $U(1)_Y$, hierarchical masses of charged fermions and small quark mixing can arise from higher-dimensional operators involving hyperon fields. Several realizations with different hyperon sectors are presented to illustrate possible flavor structures. Focusing on the realization with four hyperons, we examine neutrino mass generation through either a seesaw or a scotoseesaw mechanism, which can accommodate tiny neutrino masses and large neutrino mixing. The breaking of the dark gauge symmetry $U(1)_D$ leaves a residual $\mathbb{Z}_2$ symmetry that stabilizes dark matter, allowing either fermionic or scalar candidates with viable TeV-scale parameter regions consistent with the observed dark matter relic abundance and current direct detection constraints.
