论文摘要
我们在强子山子上重新访问标量leptoquark成对生产，并显着提高了横截面计算的精度水平。除了QCD的贡献外，我们还包括Lepton T通道交换图，根据最近的B-异常，结果与之相关。我们以QCD和简历的近级准确性评估所有贡献，在阈值范围内，在近隔到领导的对数准确度下的软光射辐射。因此，我们的预测包括迄今为止可用的最精确的Leptoquark横截面计算，对于在LHC上最佳利用Leptoquark搜索是必需的。
We revisit scalar leptoquark pair-production at hadron colliders and significantly improve the level of precision of the cross section calculations. Apart from QCD contributions, we include lepton t-channel exchange diagrams that turn out to be relevant in the light of the recent B-anomalies. We evaluate all contributions at next-to-leading-order accuracy in QCD and resum, in the threshold regime, soft-gluon radiation at next-to-next-to-leading logarithmic accuracy. Our predictions consist hence in the most precise leptoquark cross section calculations available to date, and are necessary for the best exploitation of leptoquark searches at the LHC.
