Description
The anomalous magnetic moment shows a three to four standard deviations
tension between its experimental value and theory predictions, and
therefore demands further investigation. Experiments at Fermilab and
J-PARC aim to reduce the uncertainty by a factor of four. The
theoretical uncertainty has to be reduced in equal measure. It is
dominated by the hadronic vacuum polarization (HVP) and hadronic
light-by-light (HLbL) contribution. We will present developments in
the position-space approach to the HLbL contribution.
