Representation-theoretical characterization of canonical custodial symmetry in NHDM potentials
R. Plantey, M. Aa. Solberg
By considering the basis-covariant constituents of N-Higgs-doublet potentials, we derive necessary and sufficient conditions for canonical SO(4)_C Custodial Symmetry (CS) of potent…
Computable conditions for order-2 symmetry in NHDM potentials
R. Plantey, M. Aa. Solberg
We derive necessary and sufficient conditions for order-2 () symmetry in -Higgs-doublet potentials for . The conditions, which are formulated as relations between…
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…
On the terms violating the custodial symmetry in multi-Higgs-doublet models
M. Aa. Solberg
We prove that a generic multi-Higgs-doublet model (NHDM) generally must contain terms in the potential that violate the custodial symmetry. This is done by showing that the O(4) vi…
