Estimates of the eighth-order corrections to the anomalous magnetic moment of the muon

Abstract

All the diagrams which contribute to the eighth-order muon anomaly are classified and their contributions are estimated. The Kinoshita method is used whenever possible. The total correction is estimated to be $230{\left(\frac{\alpha }{\pi }\right)}^4=6.7\mathrm{}\times {10}^{-9\mathrm{}}$.
