Leading-order hadronic contribution to the electron and muon g − 2
I present a new data driven update of the hadronic vacuum polarization effects for the muon and the electron g − 2. For the leading order contributions I find aμhad(1) = (688.57 ± 4.28) [688.91 ± 3.52] × 10−10 based on e+e− data [incl. τ data], aμhad(2) = (− 9.92 ± 0.10) × 10−10 (NLO) and aμhad(3) =...
