摘要
我们提出了完全局域减法方案 CoLoRFulNNLO 扩展到强子碰撞中色 singlet 生产的方案。我们提供明确的动量映射以及该类过程所需的完整双实减项集合。这些减项系统地从已知的 QCD 矩阵元红外极限公式中推导而来，特别注意确保其解析可积性。 resulting construction involves a relatively small number of counter-events, preserving the locality and efficiency of the scheme. All formulae have been implemented within the publicly available NNLOCAL Monte Carlo program, and we explicitly validate all IR limits using arbitrary-precision computer algebra and present representative results. The counterterms presented here constitute a self-contained subset applicable to general hadronic processes within the CoLoRFulNNLO approach.
