Query: Leading-order hadronic contributions to the electron and tau anomalous
  magnetic moments   The leading hadronic contributions to the anomalous magnetic moments of the
electron and the $\tau$-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.
