论文摘要
在局部分析部门减法的框架内，我们介绍了在最初和最终状态中以无质有色粒子为特征的过程的近级到领先阶QCD奇点的减法。该方法的特征将进行详细说明，包括引入旨在以无额外的分析复杂性为代价提高数值稳定性的优化程序。为与Lepton和Handron Collider相关的各种过程提供了数值验证。鉴于将我们的减法方法应用于QCD中近代到次要领导顺序的过程，这项工作构成了相关步骤。
Within the framework of local analytic sector subtraction, we present the subtraction of next-to-leading-order QCD singularities for processes featuring massless coloured particles in the initial as well as in the final state. The features of the method are explained in detail, including the introduction of an optimisation procedure aiming at improving numerical stability at the cost of no extra analytic complexity. A numerical validation is provided for a variety of processes relevant to lepton as well as hadron colliders. This work constitutes a relevant step in view of the application of our subtraction method to processes involving initial-state radiation at next-to-next-to-leading order in QCD.
