The Analytical Value of the Corner-Ladder Graphs Contribution to the Electron G-2 in QED

Abstract

The contributions to the (g-2) of the electron from the corner-ladder graphs in sixth-order (three-loop) QED perturbation theory are evaluated in closed analytical form. The results obtained are in excellent agreement with the most precise numerical evaluations already existing in the literature. Our results allows one to reduce the numerical uncertainty of the theoretical determination of the g-2 of the electron.
