• Computable conditions for order-2 CP symmetry in NHDM potentials 

      Plantey, Robin Maurice Yves; Solberg, Rolf Marius Aase (Journal article; Peer reviewed, 2024)
      We derive necessary and sufficient conditions for order-2 CP (CP2) symmetry in N-Higgs-doublet potentials for N>2. The conditions, which are formulated as relations between vectors that transform under the adjoint ...
    • Weinberg’s 3HDM potential with spontaneous CP violation 

      Plantey, Robin Maurice Yves; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N.; Solberg, Rolf Marius Aase (Peer reviewed; Journal article, 2023)
      We study the potential of Weinberg’s Z2 × Z2-symmetric three-Higgs-doublet model. The potential is designed to accommodate CP violation in the scalar sector within a gauge theory, while at the same time allowing for natural ...
