Eta decays at and beyond p4 in Chiral Perturbation Theory

Author

  • Johan Bijnens
  • Jürg Gasser

Summary, in English

An overview is given of Chiral Perturbation Theory and various applications to eta decays. In particular, the main decay η → 3π is discussed at the one-loop level, and estimates of the higher order corrections are given. The importance of p6 and higher order effects in double Dalitz and η → π0γγ decays is pointed out. In all these cases the need for new experimental results is stressed.
