Assessing boundedness from below in the $Z_{2} \times Z_{2}$ -symmetric three-Higgs-doublet model: algorithm and machine learning

Darius JurÄiukonis, LuÃs Lavoura, AndrÃ© 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 $S U (2)$ doublets of scal…

Perturbative unitarity for models with singlet and doublet scalars

Carolina T. Lopes, AndrÃ© Milagre, JoÃ£o P. Silva

We provide a complete description of perturbative unitarity bounds on the gauge-scalar sectors of models with extra $S U (2)$ doublet, neutral singlet, and charged singlet scalars. S…

Interplay between Electroweak Symmetry Breaking and Higgs Portal Dark Matter

Sreemanti Chakraborti, AndrÃ© Milagre, Rui Santos +1

Models of Dark Matter must contend with the fact that the presence of electroweak symmetry breaking along the thermal evolution of the Universe modifies the masses, interactions an…

Vacuum Stability Conditions for New $S U (2)$ Multiplets

We consider the addition to the Standard Model of a scalar $S U (2)$ multiplet $I^_{n}$ with dimension $n$ going from $1$ to $6$ . The multiplet $I^_{n}$ is assumed to have null vacuum ex…

Theorem on vacuum stability

We consider an extension of the Standard Model with one or more scalar multiplets beyond the Higgs doublet $I^¦$ . The additional scalar multiplets are supposed to carry arbitrary hy…
