Abstract: Models with two or more scalar doublets with discrete or global symmetries can have vacua with vanishing vacuum expectation values in the bases where symmetries are imposed. If a suitable symmetry stabilises such vacua, these… read more here.

DOI: 10.1007/jhep06(2019)119
Abstract: A bstractIn this article we study b → sμ+μ− transitions and possible correlations with the anomalous magnetic moment of the muon (aμ) within two-Higgs-doublet models with generic Yukawa couplings, including the possibility of right-handed neutrinos.… read more here.

DOI: 10.1007/jhep08(2018)195
Abstract: A bstractContrary to the standard model that does not admit topologically nontrivial solitons, two Higgs doublet models admit topologically stable vortex strings and domain walls. We numerically confirm the existence of a topological Z-string confining… read more here.

DOI: 10.3390/sym12010156
Abstract: Imposing a family symmetry on the Standard Model in order to reduce the number of its free parameters, due to the Schur’s Lemma, requires an explicit breaking of this symmetry. To avoid the need for… read more here.
