Symmetries of the 2HDM: an invariant formulation and consequences
Ferreira, Pedro M.; Grzadkowski, Bohdan; Øgreid, Odd Magne; Osland, Per (Peer reviewed; Journal article, 2021)Symmetries of the Two-Higgs-Doublet Model (2HDM) potential that can be extended to the whole Lagrangian, i.e. the CP-symmetries CP1, CP2, CP3 and the Higgs-family symmetries Z2, U(1) and SO(3) are discussed. Sufficient and ... -

Two dark matter candidates in three-Higgs-doublet models with S3 symmetry
Kuncinas, Anton; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida Nesbitt (Peer reviewed; Journal article, 2022)Models with an extended scalar electroweak sector can have vanishing vacuum expectation values in a basis where an underlying symmetry is imposed. Such extensions are very well motivated. If a symmetry prevents couplings ... -
Update on the CP-Violating Inert-Doublet Model
Grzadkowski, Bohdan; Øgreid, Odd Magne; Osland, Per; Pukhov, Alexander; Purmohammadi, Mahdi (Peer reviewed; Journal article, 2012)We have updated a recently proposed extension of the Inert Doublet Model. The extension amounts to the addition of an extra non-inert scalar doublet. The model thus offers a possibility of CP violation in the scalar sector ...
