论文摘要
我们提出了一个简单的模型，以获取可观的MUON异常磁性偶极矩（MUON $ G-2 $），引入了几个$ SU（2）_l $多重磁场，而没有任何其他对称性。仅通过$ su（2）_l $ $ u（1）_y $ $ hypercharge 1的$ su（2）_l $ seesaw seesaw speasario诱导了中微子质量矩阵。此外，我们还引入了$ su（2）_l $ su（2）_l $ QUARTET矢量fermion，并带有$ 1/2 $ HyperCharge and Scalsar and Scalsar and Scalsar and Scalsar and Scalsar and Scalsar and Scalsar and Chapherge $ 3/2 $ 3/2 $ 3/2 $ 3/2。四重奏费米昂在解释Muon $ g-2 $的过程中起着至关重要的作用，从而在环图内通过标准模型Higgs在三重态和四重奏标量玻色子之间进行混合。我们在参数空间中显示数值分析并搜索允许的区域，并演示对撞机物理。
We propose a simple model to obtain sizable muon anomalous magnetic dipole moment (muon $g-2$) introducing several $SU(2)_L$ multiplet fields without any additional symmetries. The neutrino mass matrix is simply induced via type-II seesaw scenario in terms of $SU(2)_L$ triplet Higgs with $U(1)_Y$ hypercharge 1. In addition, we introduce an $SU(2)_L$ quartet vector fermion with $1/2$ hypercharge and scalar with $3/2$ hypercharge. The quartet fermion plays a crucial role in explaining muon $g-2$ causing the chiral flip inside a loop diagram with mixing between triplet and quartet scalar bosons via the standard model Higgs. We show numerical analysis and search for allowed region in our parameter space, and demonstrate the collider physics.
