论文摘要
我们提出了一种局部减法方案，用于计算近代到领先的QCD校正，以从无色初始状态从无色初始状态中生产出大量的夸克 - 易夸克对。减法术语是按照彩色方法的方法构建的，并以使它们的整合产生紧凑，完全分析表达式的方式进行了完善。详细提供了我们的减法方案的数值实施所需的所有成分。例如，我们计算出标准模型希格斯玻色子的完全差异衰减速率，以在扰动QCD中的近代到领先的订单准确性下质量质量。
We present a local subtraction scheme for computing next-to-next-to-leading order QCD corrections to the production of a massive quark-antiquark pair from a colourless initial state. The subtraction terms are built following the CoLoRFulNNLO method and refined in such a way that their integration gives rise to compact, fully analytic expressions. All ingredients necessary for a numerical implementation of our subtraction scheme are provided in detail. As an example, we calculate the fully differential decay rate of the Standard Model Higgs boson to massive bottom quarks at next-to-next-to-leading order accuracy in perturbative QCD.
