Spontaneous symmetry breaking in the Higgs mechanism
The Higgs mechanism is very powerful: it furnishes a description of the electroweak theory in the Standard Model which has a convincing experimental verification. But although the Higgs mechanism had been applied successfully, the conceptual background is not clear. The Higgs mechanism is often presented as spontaneous breaking of a local gauge symmetry. But a local gauge symmetry is rooted in ...
متن کاملLecture Notes on Spontaneous Symmetry Breaking and the Higgs mechanism
ing the previous discussion, spontaneous symmetry breaking involves: • a C∗-algebra A (e.g., of the form (4.3)) with time-evolution α : R→ Aut(A); • a symmetry group γ : G→ Aut(A) such that αtγg = γgαt for all t ∈ R, g ∈ G. • a groundor KMS-state ω on A for which ωg ≡ γ∗ gω 6= ω for some g ∈ G. Naively, one would conversely say that SSB is absent if a symmetric groundor KMSstate exists, but thi...
متن کاملHiggs Mechanism and Symmetry Breaking without Redundant Variables
The Higgs mechanism is reconsidered in the canonical Weyl gauge formulation of quantized gauge theories, using an approach in which redundant degrees of freedom are eliminated. As a consequence, its symmetry aspects appear in a different light. All the established physics consequences of the Higgs mechanism are recovered without invoking gauge symmetry breaking. The occurence of massless vector...
متن کاملTHE FRANK KINETIC MODEL FOR SPONTANEOUS CHIRAL SYMMETRY BREAKING WITH VARIABLE CONCENTRATION OF THE ACHIRAL SUBSTRATE
This paper considers the possibility of spontaneous transition of aracemic mixture (composed of equal amounts of two enantiomeric species, say L and D) into a monochiral state (in which only one enantiomer, say L, is present). Transitions of this kind have been recently experimentally observed. A plausible approach to this phenomenon is a model put forward by Frank, based on simple laws of ...
متن کاملSpontaneous breaking of symmetry in Moyal spacetime with twisted Poincaré symmetry
After briefly reviewing the gauge symmetry in Moyal spacetimes, we analyse aspects of symmetry breaking within a quantisation program preserving the twisted Poincaré symmetry. We develop the LSZ approach for Moyal spacetimes and derive a mapping for scattering amplitudes on these spacetimes from the corresponding ones on the commutative spacetime. This map applies in the presence of spontaneous...
