abstract

We construct a three-Higgs doublet model with a flavour non-universal ${\rm U}(1)\times \mathbb{Z}_2$ symmetry. That symmetry induces suppressed flavour-changing interactions mediated by neutral scalars. New scalars with masses below the TeV scale can still successfully negotiate the constraints arising from flavour data. Such a model can thus encourage direct searches for extra Higgs bosons in the future collider experiments, and includes a non-trivial flavour structure.

Discussion (0). Continue with ORCID to comment.

  1. Deconstructed Weak Isospin from a Symplectic Symmetry

    hep-ph 2026-03 conditional novelty 6.0 of 10

    An Sp(6) completion of deconstructed weak isospin predicts six new flavour-changing gauge bosons and pushes the intermediate SU(2)^3 breaking scale above ~550 TeV (or ~150 TeV at large scale separation) via K/D mixing...

  2. Flavor Constraints in a Generational Three Higgs Doublet Model

    hep-ph 2025-02 conditional novelty 5.0 of 10

    A generational three-Higgs-doublet model is constructed, and flavor constraints show that its additional Higgs bosons can be as light as about 1.5 TeV if the only flavor violation is the minimal amount needed to repro...
