The Standard Model and Beyond ; Proceedings of the 2nd International Summer School in High Energy Physics, Muğla, 25–30 September 2006
This volume collects the edited tutorial lectures given at The Second International Summer School in High Energy Physics in Mgla, Turkey, in September 2006 - an annual event with international participation and a special focus on work done in the regions of central Asia. With emphasis on the standard model and beyond, lectures were devoted to presenting an introduction and update to many of the relevant topics, such as chiral perturbation theory, the Higgs mechanism, heavy flavour and b physics, CP violation, the AdS/CFT correspondence, ideas on grand unification and neutrino physics and astrophysics
Symmetry Breaking ; 1st ed.
Devoted to classical field theory, such a mechanism is explained in terms of the occurrence of disjoint sectors and their stability properties and of an improved version of the Noether theorem. For infinitely extended quantum systems, discussed in the second part, the mechanism is related to the occurrence of disjoint pure phases and characterized by a symmetry breaking order parameter, for which non perturbative criteria are discussed, following Wightman, and contrasted with the standard Goldstone perturbative strategy. The Goldstone theorem is discussed with a critical look at the hypotheses that emphasizes the crucial role of the dynamical delocalization induced by the interaction range. The Higgs mechanism in local gauges is explained in terms of the Gauss law constraint on the physical states.
Symmetry Breaking ; 2nd ed.
Presents a more detailed and thorough discussion of the mechanism of symmetry breaking in classical field theory in relation with the Noether theorem. Moreover, the link between symmetry breaking without massless Goldstone bosons in Coulomb systems and in gauge theories is made more explicit in terms of the delocalized Coulomb dynamics. Furthermore, the chapter on the Higgs mechanism has been significantly expanded with a non-perturbative treatment of the Higgs phenomenon, at the basis of the standard model of particle physics, in the local and in the Coulomb gauges.
