A three Higgs doublet model with symmetry-suppressed flavour changing neutral currents

Abstract

We construct a three-Higgs doublet model with a flavour non-universal $\mathrm{U}(1)\times {\mathbb{Z}}_2$ 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.
