Studies of meson decays with the Crystal Ball/TAPS setup at MAMI

Patrik Adlarson (Uppsala)

Precision studies of light meson decays are used to investigate a wide range of topics related to fundamental aspects of hadron physics. Precision measurements of meson Dalitz decays give input to hadronic determinations of the light-by-light contribution to the anomalous magnetic moment of the muon. Pseudoscalar 𝜂′ decays allow for tests of such diverse topics as 𝜋𝜋 scattering lengths, the SU(3) singlet- octet mixing angle, effective field theory and symmetries. Recently, a large statistics sample of 𝜂′ (𝜔) mesons have been produced and collected with the Crystal Ball/TAPS setup at MAMI. An overview of the physics motivations, the experimental setup and recent results are presented.
