abstract

We discuss the relation between the CP symmetry and the custodial $SU(2)$ symmetry in the Higgs sector. In particular, we show that CP violation in the Higgs-gauge sector is allowed only if the custodial $SU(2)$ symmetry is broken. We exploit these facts to constrain CP violation using the experimental bounds on $\rho-1$. CP nonconservation in the Higgs-fermion interactions can also be constrained in a similar way although a possible exception is pointed out.

  1. CP violation in H^\pm \to W^\pm Z: A physical approach for the 2HDM

    hep-ph 2026-02 conditional novelty 6.0 of 10

    H±→W±Z develops a one-loop CP-violating charge asymmetry in the 2HDM from internal bosonic and fermionic loop interferences, with the purely bosonic part vanishing in the alignment limit when the extra scalars are heavy.

  2. Dark Matter and CP Violation in Some Symmetry-Constrained 3HDMs

    hep-ph 2025-06 conditional novelty 4.0 of 10

    S3-symmetric three-Higgs-doublet models allow dark matter in a 29-42 GeV window, exclude heavy candidates above 500 GeV, and admit MeV-scale light scalars, while continuous-symmetry variants produce mass-degenerate da...
