Matching gluon scattering amplitudes and Wilson loops in off-shell regularization

High Energy Physics - Theory 2008-11-26 v2

Abstract

We construct a regularization for light-like polygonal Wilson loops in N=4{\cal N}=4 SYM, which matches them to the off-shell MHV gluon scattering amplitudes. Explicit calculations are performed for the 1-loop four gluon case. The off light cone extrapolation has to be based on the local supersymmetric Wilson loop. The observed matching concerns Feynman gauge. Furthermore, the leading infrared divergent term is shown to be gauge parameter independent on 1-loop level.
