论文摘要
III型SeeSaw是标准模型〜（SM）的简单扩展，并使用SU $（2）_ \ text {l} $ Triplet Fermion和零超收费。它可以解释小中微子质量和风味混合的起源。电动对称性破坏光中微子质量后，锯齿机构将进一步确保轻中微子和重中性Lepton Lepton质量特征状态之间的混合。如果三胞胎费米子在电动量表附近具有相当大的混合物与正确的规格对称性允许的SM扇区相当的混合，则可以在高能量攻针上产生它们，留下各种特征性的特征标志。基于对模型的简单而具体的实现，我们采用了中微子狄拉克质量矩阵的一般参数化，并执行参数扫描，以确定满足中微子振荡数据，电动eakeak精确测量的实验约束的允许区域，并分别考虑了正常和内在的群体nironer Inline shiere nirosriman。这些参数区域可以在不同的对撞机实验上进行探测。
Type-III seesaw is a simple extension of the Standard Model~(SM) with the SU$(2)_\text{L}$ triplet fermion with zero hypercharge. It can explain the origin of the tiny neutrino mass and flavor mixing. After the electroweak symmetry breaking the light neutrino mass is generated by the seesaw mechanism which further ensures the mixings between the light neutrino and heavy neutral lepton mass eigenstates. If the triplet fermions are around the electroweak scale having sizable mixings with the SM sector allowed by the correct gauge symmetry, they can be produced at the high energy colliders leaving a variety of characteristic signatures. Based on a simple and concrete realizations of the model we employ a general parametrization for the neutrino Dirac mass matrix and perform a parameter scan to identify the allowed regions satisfying the experimental constraints from the neutrino oscillation data, the electroweak precision measurements and the lepton-flavor violating processes, respectively considering the normal and inverted neutrino mass hierarchies. These parameter regions can be probed at the different collider experiments.
