Chiral perturbation theory: a basic introduction

Abstract : Chiral perturbation theory is a very general expansion method which can be applied to any dynamical system which has continuous global symmetries and in which the ground state breaks some of these spontaneously. In these lectures we explain at a basic level and in detail how such symmetries are identified in the case of the QCD Lagrangian and describe the steps which are involved in practice in the construction of a low-energy effective theory for QCD.
