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…
