摘要:

本文研究了强子对撞机上lνb \bar{b}和l+ l- b \bar{b}的产生.我们的结果,精确到下一个领先的顺序QCD,是基于自动矩阵元计算MadLoop和MadFKS进行的,并给出在两个部分子水平,和匹配后与Herwig事件发生器,实现与aMC@NLO。我们保留了对底夸克质量的完全依赖性,并精确地包括了末态轻子的所有自旋关联。我们讨论的情况下,在大型强子对撞机的几个可观的突出的重要性,准确的模拟。

英文摘要:

We present a study of lνb\bar{b} and l+ l- b\bar{b} production at hadron colliders. Our results, accurate to the next-to-leading order in QCD, are based on automatic matrix-element calculations performed by MadLoop and MadFKS, and are given at both the parton level, and after the matching with the Herwig event generator, achieved with aMC@NLO. We retain the complete dependence on the bottom-quark mass, and include exactly all spin correlations of final-state leptons. We discuss the cases of several observables at the LHC which highlight the importance of accurate simulations.
