摘要
We propose a simple model to obtain a sizable muon anomalous magnetic dipole moment (muon g - 2) that introduces several SU(2)(L )multiplet fields without any additional symmetries. The neutrino mass matrix is simply induced via a 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-like fermion with hypercharge 1/2and scalar with hypercharge 3/2. The quartet fermion plays a crucial role in explaining muon g - 2 causing the chiral flip inside a loop diagram with the mixing of triplet and quartet scalar bosons via the standard model Higgs. We conduct a numerical analysis and search for the allowed region in our parameter space and demonstrate the collider physics.
