论文摘要
我们介绍了一环平方振幅的分析结果，以$ TW $生产在强子对撞机上。使用微分方程的方法进行计算。重新归一化后，我们检查了红外差异与由异常维度预测的一般结构一致。有限的剩余成员有助于临时到领导的订单硬功能，这是红外区域附近横截面的分解配方中的重要成分之一，可用于重新召集全阶软gluon效应或基于相位空间切片方法的全阶软gluon效应或近代临界到next to-next to-next序列计算。
We present the analytic results of one-loop squared amplitudes for $tW$ production at a hadron collider. The calculation is performed using the method of differential equations. After renormalization, we have checked that the infrared divergences agree with the general structure predicted by anomalous dimensions. The finite remainder contributes to the next-to-next-to-leading order hard function, one of the essential ingredients in the factorization formula of the cross section near the infrared region, which can be used in resummation of all-order soft gluon effects or a differential next-to-next-to-leading order calculation based on the phase space slicing method.
