Chiral perturbation theory and mesons
The talk contains a short introduction to mesonic Chiral Perturbation Theory (ChPT). In addition four disparate areas where some progress has been made in recent years are discussed. These are the last fit of the order p4 low-energy-constants Lri to data, hard pion ChPT, the recent twoloop work on EFT for QCD like theories and the high order leading logarithm calculations in the massive O(N) nonli
