六边形OPE恢复与多Regge Kinetics

Hexagon OPE Resummation and Multi-Regge Kinematics

J. M. Drummond, G. Papathanasiou

摘要:

在平面N=4超Yang-Mills理论中,分析了六角威尔逊圈的双标度极限中胶子束缚态的OPE贡献.我们提供了一个系统的方法来微扰化胶子单粒子束缚态的贡献,并将结果用二元多项式表示。我们还分析了两粒子胶子束缚态的贡献,发现在解析延拓到$2\to 4$ Mandeldalle区域并传递到多Regge运动学(MRK)之后,只有单粒子胶子束缚态有贡献.从这个双尺度版本的MRK中,我们能够通过调用结果的单值性来重建MRK中多达五个循环的完整六边形剩余函数。

英文摘要:

We analyse the OPE contribution of gluon bound states in the double scaling limit of the hexagonal Wilson loop in planar N=4 super Yang-Mills theory. We provide a systematic procedure for perturbatively resumming the contributions from single-particle bound states of gluons and expressing the result order by order in terms of two-variable polylogarithms. We also analyse certain contributions from two-particle gluon bound states and find that, after analytic continuation to the $2\to 4$ Mandelstam region and passing to multi-Regge kinematics (MRK), only the single-particle gluon bound states contribute. From this double-scaled version of MRK we are able to reconstruct the full hexagon remainder function in MRK up to five loops by invoking single-valuedness of the results.
