我们将类光六边形Wilson环有限部分的双环修正与伯尔尼、狄克逊、Kosower、Roiban、Spradlin、Vergu和Volovich（arXiv：0803.1465 [hep-th]）最近对N=4 SYM理论中MHV六胶子振幅有限部分的数值结果进行了比较，并证明它们在误差条内是一致的，同时它们与BDS的修正有一个非平凡的（对偶）共形运动学不变量函数的区别。这提供了强有力的证据，威尔逊回路/散射振幅对偶持有平面N=4 SYM理论的所有循环的任意数量的外部粒子。
We compare the two-loop corrections to the finite part of the light-like hexagon Wilson loop with the recent numerical results for the finite part of the MHV six-gluon amplitude in N=4 SYM theory by Bern, Dixon, Kosower, Roiban, Spradlin, Vergu and Volovich (arXiv:0803.1465 [hep-th]) and demonstrate that they coincide within the error bars and, at the same time, they differ from the BDS ansatz by a non-trivial function of (dual) conformal kinematical invariants. This provides strong evidence that the Wilson loop/scattering amplitude duality holds in planar N=4 SYM theory to all loops for an arbitrary number of external particles.
