On vacua and bounded masses in the general 2HDM
José M. Camacho, Carlos Miró, Miguel Nebot +1
Two Higgs doublets models with a scalar potential that breaks electroweak symmetry spontaneously can have either one or two local minima. While potentials with one minimum can have…

Light states in real 3HDMs with spontaneous CP violation and softly broken symmetries
José M. Camacho, Carlos Miró, Miguel Nebot +2
Scalar sectors with several Higgs doublets, a CP invariant potential, and a CP violating vacuum, possess a mass spectrum in which, unexpectedly, new scalars cannot have masses much…

Spontaneous CP violation and symmetry in two-Higgs-doublet models with flavour conservation
João M. Alves, Francisco J. Botella, Carlos Miró +1
In multi-Higgs-doublet models, requiring simultaneously that (i) CP violation only arises spontaneously, (ii) tree level scalar flavour changing couplings are absent and (iii) the…
