论文摘要
一环可以根据简单，无关的基础编写。我们表明，对于近代领先顺序的实体贡献的相位空间积分的积分的集成存在类似的基础。我们的演示将技术从计算代数的几何形状到系统的分数集成。这是根据主积分的基础迈出了相位积分分解的第一步。
One-loop integrands can be written in terms of a simple, process-independent basis. We show that a similar basis exists for integrands of phase-space integrals for the real-emission contribution at next-to-leading order. Our demonstration deploys techniques from computational algebraic geometry to partial-fraction integrands in a systematic way. This takes the first step towards a decomposition of phase-space integrals in terms of a basis of master integrals.
