String derivation of two-loop Feynman diagrams

arXiv:hep-ph/9708471 · doi:10.1063/1.54495

Abstract

We briefly review the technology involved in extracting the field-theory limit of multiloop bosonic string amplitudes, and we apply it to the evaluation of simple two-loop diagrams involving scalars and gauge bosons.
