Light scalars in the Weinberg 3HDM potential with spontaneous CP violation
R. Plantey, O. M. Ogreid, P. Osland +2
The -symmetric 3HDM potential, sometimes called Weinberg's 3HDM potential, can accommodate both explicit and spontaneous CP violation as well as natu…
Softly broken symmetries in the 2HDM -- an invariant formulation
Pedro M. Ferreira, Bohdan Grzadkowski, Odd Magne Ogreid +1
Soft breaking of a symmetry requires an invariance of the dimension-4 part of the Lagrangian and non-trivial variation of the lower-dimensional part. However, in general, separatio…
Weinberg's 3HDM potential with spontaneous CP violation
R. Plantey, O. M. Ogreid, P. Osland +2
We study the potential of Weinberg's -symmetric three-Higgs-doublet model (3HDM). The potential is designed to accommodate CP violation in the scala…
Two dark matter candidates in three-Higgs-doublet models with symmetry
A. Kunčinas, O. M. Ogreid, P. Osland +1
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 mot…
Dark matter in a CP-violating three-Higgs-doublet model with symmetry
A. Kunčinas, O. M. Ogreid, P. Osland +1
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 experim…
