On gauge invariance and spontaneous symmetry breaking
We show how the widely used concept of spontaneous symmetry breaking can be explained in causal perturbation theory by introducing a perturbative version of quantum gauge invariance. Perturbative gauge invariance, formulated exclusively by means of asymptotic fields, is discussed for the simple example of Abelian U(1) gauge theory (Abelian Higgs model). Our findings are relevant for the electro...
متن کاملSpontaneous symmetry breaking in gauge theories.
The aim of this historical article is to describe the development of the idea of spontaneous symmetry breaking in gauge theories as seen from my perspective as a member of Abdus Salam's group at Imperial College London, UK. Beginning with an account of particle physics in the years after the Second World War, I describe early attempts at constructing a unified theory of weak and electromagnetic...
متن کاملGauge Symmetry Breaking with a Large Mass Hierarchy
Recently, new possibilities of Grand Unified Theories (GUTs) in the context of higher dimensional field theories have extensively been explored to avoid common problems of four-dimensional GUTs. The GUT symmetry breaking scale is naturally given by the inverse length of the extra dimensions, but the origin of the weak scale is still a mystery. In this paper, we propose a higher dimensional scen...
متن کاملHiggsless Gauge Symmetry Breaking with a Large Mass Hierarchy
We propose a mechanism of Higgsless gauge symmetry breaking with a large mass hierarchy. We consider a 5D gauge theory on an orbifold S1/Z2. The gauge symmetry is broken by orbifolding and also nontrivial boundary conditions at fixed points. All 4D modes which survive at low energies are found to be localized around fixed points. Supersymmetry plays an important role in our mechanism. The tree-...
متن کاملSpontaneous symmetry breaking in gauge theories via Bose-Einstein condensation
We propose a mechanism naturally leading to the spontaneous symmetry breaking in a gauge theory. The Higgs field is assumed to have global and gauged internal symmetries. We associate a non zero chemical potential to one of the globally conserved charges commuting with all of the gauge transformations. This induces a negative mass squared for the Higgs field triggering the spontaneous symmetry ...
