Abstract
Meson transition form factors describe the coupling of photons and hadrons. They are an important input to the calculations of the light-by-light scattering contribution of the anomalous magnetic moment of the muon. At the BESIII experiment in Beijing, the transition form factors of pseudoscalar mesons are studied in their Dalitz decays, in their radiative production in annihilation, and in their production in two-photon scattering. All relevant kinematic regimes are covered. An overview of the recent results and the status of the ongoing analyses is provided.
