论文摘要
在局部分析部门减法的框架内，我们介绍了使用任意数量的无质量最终状态部分的Double和Real-Virtual Entrual局部红外反反转词的完整分析集成。我们表明，仔细的相位映射选择会导致简单的分析结果，包括非单明项，可以通过常规的集成技术获得。
Within the framework of local analytic sector subtraction, we present the full analytic integration of double-real and real-virtual local infrared counterterms that enter NNLO QCD computations with any number of massless final-state partons. We show that a careful choice of phase-space mappings leads to simple analytic results, including non-singular terms, that can be obtained with conventional integration techniques.
