CP violation in H^\pm \to W^\pm Z: A physical approach for the 2HDM
Wafaa Khater, Odd Magne Ogreid, Per Osland +1
We investigate CP violation in the process H^\pm \to W^\pm Z within the framework of the two-Higgs-Doublet model (2HDM). Amplitudes are expressed transparently in terms of physical…
Systematic analysis of 3HDM symmetries
A. Kunčinas, P. Osland, M. N. Rebelo
Symmetries play a crucial role in shaping the structure and predictions of multi-Higgs-doublet models. In three-Higgs-doublet models considerable effort has been put into classifyi…
CP-violation in the Weinberg 3HDM potential
O. M. Ogreid, P. Osland, M. N. Rebelo
We explore the phenomenology of Weinberg's symmetric three-Higgs-doublet potential, allowing for spontaneous violation of CP due to complex vacuum expectation value…
-charged Dark Matter in three-Higgs-doublet models
A. Kunčinas, P. Osland, M. N. Rebelo
We explore three-Higgs-doublet models that may accommodate scalar Dark Matter where the stability is based on an unbroken -based symmetry, rather than the familiar $\mathbb{Z…
New Symmetries of the Two-Higgs-Doublet Model
Pedro M. Ferreira, Bohdan Grzadkowski, Odd Magne Ogreid +1
The Two Higgs Doublet Model invariant under the gauge group SU(2)xU(1) is known to have six additional global discrete or continuous symmetries of its scalar sector. We have discov…
Complex -symmetric 3HDM
A. Kunčinas, O. M. Ogreid, P. Osland +1
CP violation plays a very important role in nature with implications both for Particle Physics and for Cosmology. Accounting for the observed matter anti-matter asymmetry of the Un…
