Description
The anomalous magnetic moment of both electron and muon are one of the theoretically best predicted quantities. The
MSbar-onshell is a fundamental relation of QCD and an important building block for the measurement
of the top-quark mass at a future linear collider.
Both quantities lead to the same class of diagrams and can be considered together. We present first steps of the calculation
of these quantities at four-loop order.
