论文摘要
我们将一环校正计算到软异常的尺寸矩阵，以生产与强子山脉处的喷气机相关的顶部夸克对。这是迈向实施$ t \ bar {t} j + x $ hadrroductucty过程的软性 - 葡萄糖发射对数的过程迈出的一步，该过程将使$ t \ bar {t} j + x $交叉部门的准确性提高，超过当前知识。到目前为止，后者已经达到了次接头的顺序（NLO）水平，并与淋浴蒙特卡洛方法的准确性相辅相成，用于将NLO计算与Parton Showers（PS）匹配，并与具有不同数量的光Jets的矩阵元素合并。
We calculate the one-loop corrections to the soft anomalous dimension matrices for the production of a top-antitop quark pair in association with a jet at hadron colliders. This is a step forward towards implementing a procedure for the resummation of soft-gluon emission logarithms for the $t\bar{t}j + X$ hadroproduction process, that will enable the improvement of the accuracy of the $t\bar{t} j + X$ cross sections, beyond the current degree of knowledge. The latter, so far, has reached the next-to-leading order (NLO) level, complemented by the accuracy of the Shower Monte Carlo approaches used in matching the NLO computations to parton showers (PS) and by merging with matrix elements with a different number of light jets.
