QED 5-loop on the lattice

Year: 2024

Type: preprint

Abstract: We report the result of the numerical lattice computation of the lepton anomalous magnetic moment in QED up to five loops. We concentrate on the contributions from diagrams without lepton loops, which are the most difficult part of the calculation in the Feynman diagram method while the lattice formulation is the easiest. Good agreement with the results of the Feynman diagram method is observed.
