Description
An extended Higgs sector allows for reparametrizations, or different bases. These do not affect the physics. In addition, it can accommodate several genuine symmetries. These were identified some ten years ago in terms of reparametrization-invariant quantities. We have expressed these criteria in terms of physical quantities, masses and couplings.
