Description

We present the Mainz update on the determination of the hadronic vacuum polarization contribution to the muon $g-2$. We discuss ongoing improvements to our dataset and ensemble set aimed at better constraining the chiral–continuum extrapolation, as well as our efforts toward a complete estimate of isospin-breaking effects. In addition, we report on our progress in the determination of satellite observables relevant to the anomalous magnetic moment.
