Abstract

Gauge theory is the foundation of the particle physics Standard Model (SM). Considering the multiple gauge sectors for one gauge transformation, we study the generalized Abelian and non-Abelian (Yang-Mills theory) gauge theories. We first point out that the U(1) gauge theory has a few unique properties, which provide the motivations for the generalized Yang-Mills theory. Also, we consider the generalized Abelian gauge theory, and study the Higgs mechanism with new interesting properties. In addition, we propose the simple and generic generalizations of Yang-Mills theory. In the simple generalization, we realize two specific properties in the Abelian gauge theory. For applications in particle physics, we propose the invisible axion model with TeV-scale Peceei-Quinn symmetry breaking. We can solve the strong CP problem, and obtain the effective decay constant around the intermediate scale. Moreover, we study the SM electroweak symmetry breaking induced from the symmetry breaking in the other gauge Sector. In particular, we can easily obtain the strong first order electroweak phase transition in the SM, which is important for electroweak baryogenesis and gravitational wave.
