论文摘要
我们介绍了五颜六色的天线减法方法，这是QCD中近代到领先顺序（NNLO）计算的天线减法方案的重新制定。这种新方法的目的是实现NNLO减法基础设施的一般和过程无关的结构。我们依赖于在颜色空间中单循环幅度的红外奇异性结构的可预测性来生成虚拟减法项，然后，我们定义了一个可自动化的过程，以系统地推断出实际减法项的表达，并由未纳入和集成的天线功能之间的相应性指导。为了证明所描述的方法的适用性，我们在仅在Gluons的假设中计算了全彩色NNLO校正到Gluonic三射流产生$ PP（GG）\ ggg $。
We present the colourful antenna subtraction method, a reformulation of the antenna subtraction scheme for next-to-next-to-leading order (NNLO) calculations in QCD. The aim of this new approach is to achieve a general and process-independent construction of the subtraction infrastructure at NNLO. We rely on the predictability of the infrared singularity structure of one- and two-loop amplitudes in colour space to generate virtual subtraction terms and, subsequently, we define an automatable procedure to systematically infer the expression of the real subtraction terms, guided by the correspondence between unintegrated and integrated antenna functions. To demonstrate the applicability of the described approach, we compute the full colour NNLO correction to gluonic three-jet production $pp(gg)\to ggg$, in the gluons-only assumption.
