Triviality and vacuum stability bounds in the three-loop neutrino mass model
Triviality and vacuum stability bounds in the three-loop neutrino mass model
We study theoretical constraints on the parameter space under the conditions from vacuum stability and triviality in the three-loop radiative seesaw model with TeV-scale right-handed neutrinos which are odd under the $Z_2$ parity. In this model, some of the neutrino Yukawa coupling constants can be of the order of one. …
