Abstract: (Elsevier)
The n -bubble diagram contributions to the electron anomalous magnetic moment are studied. In supersymmetric QED, the photon- and photino-exchange contributions exactly cancel. When supersymmetry is broken, n ! growth is restored and Borel summability is apparently lost. The potential first renormalon singularity is absent but the second is present in both the non-supersymmetric and broken supersymmetry cases. Other possibilities for Borel summability are discussed.- quantum electrodynamics
