Abstract

We report the most general classification of 3-3-1 models with

β=3

. We found several solutions where anomaly cancellation occurs among fermions of different families. These solutions are particularly interesting as they generate non-universal heavy neutral vector bosons. Non-universality in the standard model fermion charges under an additional gauge group generates charged lepton flavor violation and flavor changing neutral currents; we discuss under what conditions the new models can evade constraints coming from these processes. In addition, we also report the Large Hadron Collider~(LHC) constraints.

带有异种电荷的 3-3-1 备选模型

我们报告了 β=3 的 3-3-1 模型的最一般分类。我们发现了几种在不同系的费米子之间发生反常抵消的解。这些方案特别有趣，因为它们产生了非普遍的重中性矢量玻色子。标准模型费米子电荷在额外规规群下的非普遍性产生了带电轻子的味道违反和味道变化的中性电流；我们讨论了新模型在什么条件下可以规避来自这些过程的约束。此外，我们还报告了大型强子对撞机（LHC）的约束。
