标题： Multichannel Conformal Blocks for Polygon Wilson Loops

摘要： 我们引入了与多通道共形块相关的概念，这对于具有超过六条边的零多边形威尔逊环的算子乘积展开是重要的。作为这些概念的应用，我们分解了一环七边形威尔逊环，并预测了其二环OPE不连续性的值。在函数层面上，OPE不连续性大约是完整结果的一半。使用符号，它们足以预测完整的二环结果。我们还提出了关于七边形结果在任何环序下的几个新预测。 显示英文摘要

摘要： We introduce the notion of Multichannel Conformal Blocks relevant for the Operator Product Expansion for Null Polygon Wilson loops with more than six edges. As an application of these, we decompose the one loop heptagon Wilson loop and predict the value of its two loop OPE discontinuities. At the functional level, the OPE discontinuities are roughly half of the full result. Using symbols they suffice to predict the full two loop result. We also present several new predictions for the heptagon result at any loop order.
