In this talk, I will discuss the construction of the multi-Higgs Doublet Model (n-HDM) based on the Maximal symmetry Sp(2n$)/Z_2$. The maximal symmetry n-HDM provides the natural SM alignment limit which is a phenomenologically rich framework with a special feature of unification of all quartic couplings. The list of most possible accidental symmetries as subgroups of symplectic group Sp(2n$)/Z_2$

We show that biquadratic potentials admit nontrivial flat directions when the determinant of the quartic coupling matrix of the scalar fields vanishes. This consideration suggests a new approach to the problem of finding flat directions in scale-invariant theories, noticeably simplifying the study of scalar potentials involving many fields. The method generalizes to arbitrary quartic potentials by

In my presentation I will be considering non-standard models with additional scalar triplets: without modification of the gauge group (Higgs Triplet Model - HTM) and with extended gauge group $SU(2)_R x SU(2)_L x U(1)$ (Left Right Symmetric Model - LRSM). Those two models vary in the triplet vacuum expectation value (VEV). Within the HTM we have to keep the triplet VEV at most at the range of GeV

Imposing one of the symmetries (CP1, Z_2, U(1), CP2, CP3, SO(3))on the 2HDM potential implies certain constraints on the masses and couplings of the model. These constraints are expressed in terms of a minimal set, consisting of 11 masses and couplings.

I introduce generally applicable strategies for the construction of basis invariants in multi-Higgs models. Applied to the two Higgs doublet model (2HDM), this allows us to find the full set of generating (CP-even and CP-odd) basis invariants. The complete ring of basis invariants is constructed, and novel relations between the CP-odd basis invariants emerge. This allows to derive the basis invari

We discuss the scalar sector of a class of BSM models with enlarged gauge symmetry, the so called 331 models. For all of them the gauge group is $SU(3)_c\times SU(3)_L \times U(1)_X$ but, depending on a parameter entering in the definition of the electric charge operator, they allow different kind of new particles. Interestingly, the scalar potential is universal for the 331 models. We give an ove

The precise study of the properties of the Higgs boson offers a unique and crucial opportunity to probe Beyond-the-Standard-Model (BSM) Physics indirectly. Among these, the Higgs trilinear coupling is of particular importance, because it determines the shape of the Higgs potential and in turn the nature of the electroweak phase transition (EWPT). It has been known for some time that, in a variety
