Abstract content
It is pointed out why a good understanding of the electromagnetic properties of light mesons is mandatory to explore the structure of hadrons, but also to improve the Standard Model predictions for quantities like $g-2$ of the muon or the rare decay of pseudoscalars to a dilepton [1]. Recent results for meson transition form factors, two-photon reactions and related quantities are shown [2,3,4].
