Status of Strong ChPT

High Energy Physics - Phenomenology 2009-04-24 v1

Abstract

The present status of Chiral Perturbation Theory (ChPT) in the strong mesonic sector is discussed. A very short introduction to ChPT is followed by an overview of existing two-loop calculations and the determination of the Low-Energy-Constants (LECs). I discuss the case of ηπππ\eta\to\pi\pi\pi decays in somewhat more detail and finish by mentioning some recent work on partially quenched ChPT and on the renormalization group in ChPT.
