Spontaneous Symmetry Breaking in Fermion - Gauge Systems : A Non Standard Approach
We propose a new method for the study of the chiral properties of the ground state in QFT’s based on the computation of the probability distribution function of the chiral condensate. It can be applied directly in the chiral limit and therefore no mass extrapolations are needed. Furthermore this approach allows to write up equations relating the chiral condensate with quantities computable by s...
متن کاملInvestigation of Spontaneous Symmetry Breaking from a Non Standard Approach
We propose a new method for the study of the chiral properties of the ground state in Quantum Field Theories (QFT 0 s) which is based on the computation of the probability distribution function (p:d:f:) of the chiral condensate in the chiral limit. We show how despite of the fact that Grassmann variables cannot be simulated on a computer, an analysis of spontaneous symmetry breaking without a s...
متن کاملSpontaneous Symmetry Breaking in Non Abelian Gauge Theories
This term paper explores the phenomenon of spontaneous symmetry breaking in systems with non-abelian gauge symmetry. The most famous example comes from the standard model of particle physics, wherein symmetry breaking is responsible for the masses of the W and Z bosons and the corresponding short range of the weak nuclear force. The electroweak theory will be discussed as well as a more ambitio...
متن کاملSpontaneous Family Symmetry Breaking And Fermion Mixing
We propose a theory to describe fermion mixing. The theory respects the maximal abelian family symmetries which are spontaneously broken down at a large scale. We find that quark mixing can be well described in this theory. Some concrete models are constructed. The crucial point for model building is to introduce some new particles which are SU(2) gauge singlets and carry -1/3 electric charge. ...
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...
