QED logarithms in the electroweak corrections to the muon anomalous magnetic moment
QED logarithms in the electroweak corrections to the muon anomalous magnetic moment
We employ an effective Lagrangian approach to derive the leading-logarithm two-loop electroweak contributions to the muon anomalous magnetic moment, a_mu. We show that these corrections can be obtained using known results on the anomalous dimensions of composite operators. We confirm the result of Czarnecki et al. for the bosonic part …
