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 QFTs based on the computation of the probability distr ibution function of the chiral condensate. It can be applied directly in the chiral limit and therefore no mass extrapolations are needed. F urthermore this approach allows to write up equations relating the chi ral condensate with quantities computable by standard numerical method s, the functional form of these relations depending on the broken symm etry group. As a check, we report some results for the compact Schwing er model.
