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…

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-dime…

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 ex…

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 hy…

On the extension of the SM through a scalar quadruplet

Darius Jurčiukonis, Luís 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…
