我们提出了在大型强子对撞机（LHC）中与最多两个额外的硬喷流相关联的夸克和胶子生产的截面预测。与包容性出生率相比，这些横截面可能非常大。由于强子对撞机实验利用硬射流来重建级联衰变，或者作为分离方克和胶子产生的一种方式，因此对这些过程的理解至关重要。我们展示了硬射流辐射在多大程度上可以用阵雨算法来描述，并指出如何调整这些阵雨，例如顶夸克对的产生，可以帮助减少LHC新物理搜索的理论不确定性。
We present cross section predictions for squark and gluino production at the LHC, in association with up to two additional hard jets. These cross sections can be very large in comparison to the inclusive Born rates. Because hadron collider experiments utilize hard jets in the reconstruction of cascade decays or as a way to separate squark and gluino production, the understanding of these processes is crucial. We show to what degree hard jet radiation can be described by shower algorithms and point out how tuning these showers, for example to top quark pair production, could help reduce theoretical uncertainties for new physics searches at the LHC.
