One-loop neutrino mass model without any additional symmetries

We propose a radiative seesaw model at one-loop level, introducing fields with large multiplet of SU(2)(L). Thanks to large representations, any additional symmetries are not needed. In this framework, we formulate lepton and new fermion sector such as mass matrices, LFVs, and muon g-2. Furthermore, we show our cut-off scale via RGEs of SU(2)(L), and numerical analysis at a benchmark point included in dark matter candidate. Finally, we briefly discuss processes producing exotic particles in our model via proton-proton collision and possibility of detecting them at the large hadron collider experiments.
