A simple method to detect spontaneous CP violation in multi-Higgs models
Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Peer reviewed; Journal article, 2017) -
CP violation in extended Higgs sectors
Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Journal article; Peer reviewed, 2018)We discuss how one can identify CP violation (and conservation) in multi-Higgs-doublet potentials. After a brief review of CP violation in the 2HDM, we refer to the fact that for NHDM with N ≥ 3 the well known methods ... -
CP Violation in the scalar sector
Emmanuel-Costa, David; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Peer reviewed; Journal article, 2016) -
Dark matter in a CP-violating three-Higgs-doublet model with S3 symmetry
Kuncinas, Anton; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Peer reviewed; Journal article, 2022)In spite of the success of the Standard Model of particle physics, there are some theoretical predictions which are not yet fully established experimentally, as well as some experimental observations which cannot be fitted ... -
Implications of symmetries in the scalar sector
Haber, Howard E.; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Peer reviewed; Journal article, 2020)Symmetries play a very important rôle in Particle Physics. In extended scalar sectors, the existence of symmetries may permit the models to comply with the experimental constraints in a natural way, and at the same time ... -
S3-inspired three-Higgs-doublet models: A class with a complex vacuum
Kuncinas, Anton; Osland, Per; Øgreid, Odd Magne; Rebelo, Margarida N. (Peer reviewed; Journal article, 2020)In this paper we analyze in detail an S3-symmetric three-Higgs-doublet model with a specific vacuum configuration. This analysis allows us to illustrate important features of models with several Higgs doublets, such as the ... -
Spontaneous symmetry breaking in the S 3-symmetric scalar sector
Emmanuel-Costa, David; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Peer reviewed; Journal article, 2016) -
Spontaneous symmetry breaking in three-Higgs-doublet S3-symmetric models
Emmanuel-Costa, David; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Peer reviewed; Journal article, 2017) -
Symmetries and mass degeneracies in the scalar sector
Haber, Howard E.; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Peer reviewed; Journal article, 2019)We explore some aspects of models with two and three SU(2) scalar doublets that lead to mass degeneracies among some of the physical scalars. In Higgs sectors with two scalar doublets, the exact degeneracy of scalar masses, ... -
