Abstract: (Elsevier)
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 hadronic light-by-light contribution to aμ by using dispersive techniques combined with a dedicated experimental program to obtain the required hadronic input.
