Leading-order hadronic contributions to the electron and tau anomalous magnetic moments

Abstract
The leading hadronic contributions to the anomalous magnetic moments of the electron and the $Ï$-lepton are determined by a four-flavour lattice QCD computation with twisted mass fermions. The continuum limit is taken and systematic uncertainties are quantified. Full agreement with results obtained by phenomenological analyses is found.
