Measurements of Meson Transition Form Factors — •Susan Schadmand — Forschungszentrum Jülich

This talk will give an experimental overview of the electromagnetic transition form factors of light mesons. In particular, the results from WASA-at-COSY and CLAS6 are presented. At Forschungszentrum Jülich, π⁰ and η mesons were produced in proton-proton reactions at the COSY accelerator where the WASA detector was used to detect all final-state particles. At Jefferson Lab, the g12 experimental run used a tagged photon beam on protons to produce mesons up to the φ meson where the CLAS6 detector recorded charged particles including final states with dileptons.
