The muon g ― 2
TL;DR: In this article, the authors present a review of the status of the theoretical prediction and in particular discuss the role of the hadronic vacuum polarization effects and hadronic light-by-light scattering correction, including a new evaluation of the dominant pion exchange contribution.

Harmonic sums and Mellin transforms up to two-loop order
Johannes Blümlein,Stefan Kurth +1 more
TL;DR: In this article, a systematic study on the finite harmonic sums up to level four was performed, and the authors derived algebraic relations connecting these sums to obtain representations based on a reduced set of basic functions.

Predictions for g-2 of the muon and alpha(QED)(M-Z(2))
TL;DR: In this article, a wide variety of data for the e+e−production of hadrons and their uncertainties were combined to obtain the optimum form of R(s)[equivalent]sigmahad0(s)/sigmapt(s), together with its uncertainty.
Journal ArticleDOI
On High Order Estimates in QED
TL;DR: In this article, it was shown that there are single gauge invariant diagrams contributing to the leptonic g − 2 for which the amplitude grows like n! in the n 'th order.

Fourth-Order Corrections in Quantum Electrodynamics and the Magnetic Moment of the Electron

TL;DR: The covariant S matrix formalism of Dyson has been applied to the calculation of the fourth-order radiative correction to the magnetic moment of the electron in this paper, and the results for the covariant Δ-functions which describe the interaction of virtual electrons and photons with the vacuum are given to order α.

Anomalous Magnetic Moment of the Electron, Muon, and Nucleon
Sidney D. Drell,Heinz Pagels +1 more
TL;DR: The anomalous magnetic moment of the electron was computed using dispersion theory in this paper, where the anomalous moment was derived from the low-energy behavior of the photon system near the threshold of the absorptive amplitude.
