Is the Higgs boson associated with ColemanWeinberg dynamical symmetry breaking?
Abstract
The Higgs mechanism may be a quantum phenomenon, i.e., a ColemanWeinberg potential generated by the explicit breaking of scale symmetry in Feynman loops. We review the relationship of scale symmetry and trace anomalies, and we show that the ColemanWeinberg potential can be defined as the solution to a differential renormalization group equation that follows from the trace of the improved stress tensor. We propose a simple phenomenological model with "maximal visibility" at the LHC containing a "dormant" Higgs doublet [no VEV, coupled to standard model gauge interactions SU(2)×U(1)] with a mass of ̃380 GeV. We discuss the LHC phenomenology and UV challenges of such a model. We also give a schematic model in which new heavy fermions, with masses ̃230 GeV, can drive a ColemanWeinberg potential at two loops. The role of the "improved stress tensor" is emphasized, and we propose a nongravitational term, analogous to the θ term in QCD, which generates it from a scalar action.
