A duality relation has been proposed between the planar gluon MHV amplitudes and lightlike Wilson loops in N=4 super Yang–Mills. At sixpoint twoloop, the results for the planar gluon MHV amplitude and for the lightlike Wilson loop agree, but they both differ from the Bern–Dixon–Smirnov ansatz by a finite remainder function. Recently Del Duca, Duhr and Smirnov presented an analytical result for the twoloop hexagon Wilson loop remainder function in general kinematics. Their result is rather lengthy, and the dependence on the conformal cross ratios appears in a complicated way. Here we present an alternate, more
compact representation
for the twoloop hexagon Wilson loop remainder function.
