Multiloop Calculations in QED by Superparticle Path Integrals
Abstract
We use the worldline path integral approach to the Bern-Kosower formalism for extending this formalism to the calculation of higher order corrections to N - photon scattering. The case of the two-loop QED β-function is considered in detail.
