摘要：
We discuss status and prospects of a dispersive analysis of the eta and eta' transition form factors. Particular focus is put on the various pieces of experimental information that serve as input to such a calculation. These can help improve on the precision of an evaluation of the eta and eta' pole contributions to hadronic light-by-light scattering in the anomalous magnetic moment of the muon.
