A three Higgs doublet model with symmetrysuppressed flavour changing neutral currents
Abstract
We construct a threeHiggs doublet model with a flavour nonuniversal U(1) × &Z;_{2} symmetry. That symmetry induces suppressed flavourchanging 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 nontrivial flavour structure.
