Conditions for boundedness from below of a -symmetric three-Higgs-doublet model
Darius Jurčiukonis, Luís 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-dimen…
Assessing boundedness from below in the -symmetric three-Higgs-doublet model: algorithm and machine learning
Darius Jurčiukonis, Luís Lavoura, André Milagre
The scalar potential of any particle-physics model must be bounded from below (BFB). We consider the extension of the Standard electroweak Model with three doublets of scal…
On the addition of an quadruplet of scalars to the Standard Model
Darius Jurčiukonis, Luís Lavoura
We consider the extension of the Standard electroweak Model through an quadruplet of scalars with hypercharge either or (with an additional reflection symmetry…
Vacuum Stability Conditions for New Multiplets
André Milagre, Darius Jurčiukonis, Luís 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 expe…
Constraints on large scalar multiplets added to the Standard Model
Darius Jurčiukonis, Luís Lavoura
We study the extension of the Standard Model (SM) by introducing a scalar multiplet with arbitrary isospin and hypercharge . We explicitly consider various possible values o…
Theorem on vacuum stability
André Milagre, Luís Lavoura
We consider an extension of the Standard Model with one or more scalar multiplets beyond the Higgs doublet . The additional scalar multiplets are supposed to carry arbitrary hyp…
