It is known that the CP-even and CP-odd scalars contribute with an opposite sign to the anomalous magnetic moment of the muon.
We study popular scalar extensions of the Standard Model, namely the singlet extension, the 2-Higgs doublet model (2HDM) and the doublet plus singlet extension.
We show that these models are incapable of explaining the observed discrepancy in (g−2)_\mu, with the exce

We study the discovery prospects of heavy neutral higgs bosons in Beyond the Standard Model scenarios where it cascade decays to a lighter scalar eigenstate which subsequently decays to the Standard Model Higgs. We consider either of 4 leptons and 2 b-jets or of 2 leptons + 4 b-jets final states. We find that these two signatures allows us to both optimally reduce the Standard Model backgrounds an

We consider the electroweak production of multiple Higgs bosons at the LHC in the two-Higgs doublet model (2HDM). We show that in realistic models the electroweak cross sections for production of 2 or 3 Higgs bosons can dominate over QCD production. This is because in a gg-initiated process, production via a resonant Z in the s-channel is prohibited according to the Landau-Yang theorem, which is n

A straightforward method to translate the potential parameters of the 2HDM into physical masses and couplings is presented. The method is applied to CP-odd and CP-even weak-basis invariants of the model in order to express them exclusively in terms of the physical observable masses and couplings.

We would like to show how stability, electroweak
symmetry breaking and symmetries may be studied in models with
various Higgs-boson doublets.

A general Two Higgs Doublet Model includes uncontrolled sources of tree level flavour violation in neutral couplings. In popular cases like type I or II, the imposition of a symmetry forbids them. We explore scenari where a symmetry requirement, rather than removing them, allows for their presence in a controlled manner. Phenomenological consequences of those controlled tree level FCNC are explore

We discuss composite two Higgs doublet models based on the global symmetry breaking SO(6) to SO(4)*SO(2). We construct two Higgs doublets emerging from 8 pseudo Nambu-Goldstone bosons, and then show how the scalar potential is generated through the Coleman-Weinberg mechanism at one-loop level.
We also show several phenomenologically viable scenarios, a mass spectrum of Higgs bosons, their couplin

The Two-Higgs-doublet model (2HDM) is one of the most studied extensions of the Standard Model. But just as the other popular "New Physics" models, it gets more and more constrained by recent experimental progress, especially by the LHC data. For all four 2HDM types with a softly broken Z2 symmetry, we present updated results of global analyses obtained with the open-source HEPfit code. We obtain
