Two-loop Feynman Diagrams in Yang-Mills Theory from Bosonic String Amplitudes

We present intermediate results of an ongoing investigation which attempts a generalization of the well known one-loop Bern Kosower rules of Yang-Mills theory to higher loop orders. We set up a general procedure to extract the field theoretical limit of bosonic open string diagrams, based on the sewing construction of higher loop world sheets. It is tested with oneand two-loop scalar field theo...

From Trees to Loops and Back

We argue that generic one-loop scattering amplitudes in supersymmetric Yang-Mills theories can be computed equivalently with MHV diagrams or with Feynman diagrams. We first present a general proof of the covariance of one-loop non-MHV amplitudes obtained from MHV diagrams. This proof relies only on the local character in Minkowski space of MHV vertices and on an application of the Feynman Tree ...

Exact Combinatorics of Bern - Kosower - type Amplitudes for Two - Loop Φ 3 Theory

Counting the contribution rate of a world-line formula to Feynman diagrams in φ theory, we explain the idea how to determine precise combinatorics of Bern-Kosower-like amplitudes derived from a bosonic string theory for N -point two-loop Feynman amplitudes. In this connection we also present a method to derive simple and compact world-line forms for the effective action. PACS: 11.15.Bt; 11.55.-...
