We review the present status of the Standard Model calculation of the anomalous magnetic
moment of the muon. This is performed in a perturbative expansion in the fine-structure …

In this work we study the axial contributions to the hadronic light-by-light piece of the muon
anomalous magnetic moment. We point out some theoretical ambiguities in previous …

This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …

In view of the current 3–4 σ deviation between theoretical and experimental values for the
muon's anomalous magnetic moment, we review the ongoing efforts in constraining the …

A bstract Estimating the contribution from axial-vector intermediate states to hadronic light-by-
light scattering requires input on their transition form factors (TFFs). Due to the L andau–Y …

We reassess the impact of short-distance constraints for the longitudinal component of the
hadronic light-by-light amplitude on the anomalous magnetic moment of the muon, a μ=(g-2) …

We evaluate the light-quark meson contributions to three exact light-by-light scattering sum
rules in light of new data by the Belle Collaboration, which recently has extracted the …

A bstract We study the transition form factors (TFFs) of axial-vector mesons in the context of
currently available experimental data, including new constraints from e+ e−→ f 1 (1285) π+ …

We develop the formalism to provide an improved estimate for the hadronic light-by-light
correction to the muon's anomalous magnetic moment a_ μ a μ, by considering single …
