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…

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…

On the addition of a large scalar multiplet to the Standard Model
Darius Jurčiukonis, Luís Lavoura
We consider the addition of a single multiplet of complex scalar fields to the Standard Model (SM). We explicitly consider the various possible values of the weak isospin $…
