标题： Reduction of Feynman Integrals in the Parametric Representation IV: Integrals with Irregular Integration Regions

摘要： 参数费曼积分，其积分区域由某些多项式定义，在本文中进行了研究。 已经证明，具有不规则积分区域的积分可以转换为标准参数积分，对于这些积分已知一种约简方法。 本文展示了该方法在三点能量关联函数的解析计算中的应用。 原则上，这种方法适用于更一般的事件形状，甚至喷注观测量。 显示英文摘要

摘要： Parametric Feynman integrals with the regions of integration defined by some polynomials are considered in this paper. It is shown that integrals with irregular integration regions can be converted to standard parametric integrals, for which a reduction method is known. An application of this method to the analytic calculation of three-point energy correlators is presented. In principle, this method applies to more general event shapes and even jet observables.
