Analytical on shell QED results: 3-loop vacuum polarization, 4-loop $\beta$-function and the muon anomaly
We present the results of analytical calculations of the 3-loop contributions to the asymptotic photon vacuum polarization function, in the on shell scheme, and of the 4-loop contributions to the on shell QED beta-function. These are used to evaluate various 4-loop and 5-loop contributions to the mu...
