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.Comment: 7 pages, 1 figure, contributed to Beyond the Standard Model V, Balholm, Norway, April 1997.
