The Two-Loop Euler-Heisenberg Lagrangian in Dimensional Renormalization
arXiv:hep-th/9704194 · doi:10.1007/BF02634170
Abstract
We clarify a discrepancy between two previous calculations of the two-loop QED Euler-Heisenberg Lagrangian, both performed in proper-time regularization, by calculating this quantity in dimensional regularization.
