A theoretical study of meson transition form factors

Understand

In this thesis we discuss a rational and data-based description of the single- and double-virutal transition form factors of the lightest pseudoscalar mesons.

• We obtain an accurate description of these in the spacelike and low-energy timelike regions.
• The phenomenological applications are wide.
• Among them, we discuss, the eta-eta' mixing, the rare pseudoscalar decays into a lepton pair and the pseudoscalar-pole contribution to the hadronic light-by-light part of the anomalous magnetic moment of the muon.
