Vacuum stability in U(1)-prime extensions of the Standard Model with TeV scale right handed neutrinos
We investigate a minimal U(1)′ extension of the Standard Model with one extra complex scalar and generic gauge charge assignments. We use a type-I seesaw mechanism with three heavy right handed neutrinos to illustrate the constraints on the charges, on their mass and on the mixing angle of the two s...
