Strong Interactions at Low Energy

High Energy Physics - Phenomenology 2015-06-25 v1

Abstract

The lectures review some of the basic concepts relevant for an understanding of the low energy properties of the strong interactions: chiral symmetry, spontaneous symmetry breakdown, Goldstone bosons, quark condensate. The effective field theory used to analyze the low energy structure is briefly sketched. As an illustration, I discuss the implications of the recent data on the decay KππeνK\to \pi\pi e\nu for the magnitude of the quark condensate.
