Higher-Order Hadronic Contributions to the Anomalous Magnetic Moment of Leptons

  title={Higher-Order Hadronic Contributions to the Anomalous Magnetic Moment of Leptons},
  author={Bernd Krause},
Higher-order hadronic contributions to the anomalous magnetic moment of the electron, muon, and τ lepton are considered in detail. As a main result we find a reduction by −18 × 10 for the g-2 of the muon as compared to previous calculations. Analytical expressions for the kernel functions of higher-order hadronic effects are presented. We employ the method of asymptotic expansions to calculate kernel functions analytically in terms of a series expansion in the lepton mass. The complete… CONTINUE READING
