Abstract [en]

Decays of eta and eta ' mesons are a laboratory for low energy strong interactions. The rate of isospin breaking decays into three pions constrain ratios of the light quark masses. Particle distributions from hadronic decays allow to study the elementary processes of the low energy Quantum Chromodynamics: pi-pi and pi-eta interactions. Radiative and conversion decays of the eta and eta ' mesons provide information about internal structure of the mesons and the decay mechanism is strongly influenced by vector meson resonances. The lecture gives an introduction to the common decays of eta and eta ' mesons. The main the me of the lecture are three body decays: hadronic decays, radiative decays into pi(+)pi(-), pi(0)gamma gamma and Dalitz decays into l(+)l(-)gamma.
