Present Status of Chiral Perturbation Theory
A. Pich🇪🇸
Abstract
The basic ideas and methods of chiral perturbation theory are briefly reviewed. I discuss the recent attempts to build an effective Lagrangian in the resonance region and summarize the known large-N_C constraints on the low-energy chiral couplings.
