论文摘要
我们研究了大型强子对撞机（LHC）Energies $ t $ channel单夸克生产的建模。我们将5Favor方案的预测与4FARAIVE方案的临近序列进行比较，以4型风味方案的方式进行比较，发现这两个方案一般在几个百分之几中同意了顶级夸克的运动学分布的形式。 5味方案中的预测在归一化和分布方面都表现出较强的稳定性，并且优于可比较顺序的4味方案的稳定性。我们将预测与LHC数据进行比较。我们的发现为LHC的单个Quark物理学精确研究提供了明确的理论指导。
We study the modeling of $t$-channel single top-quark production at Large Hadron Collider (LHC) energies. We compare predictions at next-to-next-to-leading order in a 5-flavor scheme to those of next-to-leading order in a 4-flavor scheme, finding the two schemes agree within a few percent in general for the shape of kinematic distributions of the top quark. The predictions in the 5-flavor scheme show strong stability for both normalization and distributions, and are superior to those of the 4-flavor scheme at comparable orders. We present comparisons of the predictions with LHC data. Our findings provide clear theoretical guidance for precision studies of single top-quark physics at the LHC.
