Eta decays at and beyond p(4) in Chiral Perturbation Theory

Author

  • Johan Bijnens
  • J Gasser

Summary, in English

An overview is given of Chiral Perturbation Theory and various applications to eta decays. In particular. the main decay eta --> 3pi is discussed at the one-loop level, and estimates of the higher order corrections are given. The importance of p(6) and higher order effects in double Dalitz and eta --> pi(0)gammagamma decays is pointed out. In all these cases the need for new experimental results is stressed.
