O $$ \mathcal{O} $$ (mα 2(Zα)6) contribution to Lamb shift from radiative corrections to the Wichmann-Kroll potential

Abstract

Abstract We derive an analytical expression for the contribution of the order mα 2(Zα)6 to the hydrogen Lamb shift which comes from the diagrams for radiative corrections to the Wichmann-Kroll potential. We use modern methods of multiloop calculations, based on IBP reduction, DRA method and differential equations.
