Excitations of gauge bosons, and other aspects of gauge Higgs theories

Abstract

I review the qualitative physical distinction between the Higgs and confinement phases of a gauge Higgs theory, and the non-local order parameter introduced by Matsuyama and myself which identifies the two phases. I then present some new results suggestive of a possible excitation spectrum of vector bosons in the electroweak sector of the Standard Model.
