Abstract

Abstract For 50 years, the standard model of particle physics has been very successful in describing subatomic phenomena. In the past quarter of a century, this was challenged by a mismatch between its predictions and precision measurements of the anomalous magnetic moment of the muon, a μ . This disagreement was eventually reconciled, first through a determination in an ab initio lattice calculation 1 of the most uncertain theoretical contribution, the leading-order hadronic vacuum polarization (LO-HVP), $${a}_{\mu }^{\text{LO-HVP}}$$ a μ LO-HVP , and subsequently by experimental results 2 and updates of the reference standard-model predictions using lattice results for $${a}_{\mu…
