Higgs-Free Symmetry Breaking from Critical Behavior near Dimension Four

Abstract

Starting from the infrared limit of Yang-Mills theory, we introduce here a Higgs-free model in which symmetry breaking arises from critical behavior near dimension four. Electroweak bosons develop mass near the Wilson-Fisher point of Renormalization Group flow. The family structure of Standard Model is recovered using the technique of “epsilon expansion”. We also find that dimensional regularization offers a straightforward solution to the cosmological constant problem.
