Abstract

The most general SU(2) × U(1)Y -symmetric quartic potential with two Higgs doublets, subject to an only softly broken discrete symmetry (φ1, φ2) → (−φ1, φ2), is considered. At tree-level, analytic bounds on the parameters are derived that ensure a stable vacuum, breaking SU(2) × U(1)Y down to U(1)em.
