Conditions for boundedness from below of a -symmetric three-Higgs-doublet model
Darius JurÄiukonis, LuÃs Lavoura
We investigate the orbit space of the scalar potential of a -symmetric three-Higgs-doublet model. We find that, if the potential enjoys invariance, then its three-dime…

Vacuum Stability Conditions for New Multiplets
André Milagre, Darius JurÄiukonis, LuÃs Lavoura
We consider the addition to the Standard Model of a scalar multiplet with dimension going from to . The multiplet is assumed to have null vacuum ex…

On the extension of the SM through a scalar quadruplet
Darius JurÄiukonis, LuÃs Lavoura
We consider the extension of the Standard Model (SM) through a scalar quadruplet with hypercharge either or ; in the first case, we assume invariance of the scalar…
