在NLO + NLL中，具有改进的PDF的LHC处的电弱子和slepton对产生
Electroweakino and slepton pair production at the LHC in NLO+NLL with resummation-improved PDFs
摘要：
使用部分子密度函数（PDF）与阈值再确认的改进，我们一贯计算希格西诺/高吉诺和slepton对生产下一个领先的顺序和下一个领先的对数精度在大型强子对撞机。较小的PDF不确定性的全球PDF集利用因式分解的方法，这也避免了在梅林空间中的阈值重建改进的PDF副本的改装中出现的并发症。我们明确地考虑到减少规模的不确定性，由于重申。我们发现，在PDF拟合的重结晶贡献部分补偿的截面增强引起的部分子矩阵元。
英文摘要：
Using parton density functions (PDFs) with threshold-resummation improvement, we consistently calculate higgsino/gaugino and slepton pair production at next-to-leading order and next-to-leading logarithmic accuracy at the LHC. The smaller PDF uncertainty of the global PDF sets is exploited with a factorisation method, which also avoids complications arising in the refitting of threshold-resummation improved PDF replicas in Mellin space. We explicitly take into account the reduction of the scale uncertainty due to the resummation. We show that the resummation contributions in the PDF fits partially compensate the cross section enhancements induced by those in the partonic matrix elements.
