Inverse seesaw model with a natural hierarchy at the TeV scale
Inverse seesaw model with a natural hierarchy at the TeV scale
We propose a new kind of inverse seesaw model without any additional symmetries. Instead of the symmetries, we introduce several fermions and bosons with higher $SU(2)_L$ representations. After formulating the Higgs sector and neutrino sector, we show that the cut-off energy, which is valid to our model, is at around …
