Symmetry breaking in the standard model : a non-perturbative outlook [Documento eletrónico] / by Franco Strocchi. - Pisa : Scuola Normale Superiore : Edizioni della Normale , 2019 . - 106 p.. - (Lecture Notes (Scuola Normale Superiore)) ; 19 The book provides a non-perturbative approach to the symmetry breaking in the standard model, in this way avoiding the critical issues which affect the standard presentations. The debated empirical meaning of global and local gauge symmetries is clarified. The absence of Goldstone bosons in the Higgs mechanism is non-perturbatively explained by the validity of Gauss laws obeyed by the currents which generate the related global gauge symmetry. The solution of the U(1) problem and the vacuum structure in QCD are obtained without recourse to the problematic semiclassical instanton approximation, by rather exploiting the topology of the gauge group.
