Description
Precision studies of light mesons decays are used to study a wide range of topics related to fundamental aspects of hadron physics. Besides tests of fundamental symmetries of the Standard Model, precision data of η and η’ decays provide a testing ground for effective field theory. In addition, measurements of the η and η’ transition form factors give valuable information on the hadronic light-by-light contribution to the anomalous magnetic moment of the muon. With the Crystal Ball-TAPS detector setup at the Mainz Microtron, large statistics samples of η and η’ have been collected. An overview of the experimental setup and recent results on electromagnetic η and η’ decays are presented.
