我们对顶夸克有效理论与 Tevatron 以及大型强子对撞机运行 I 和 II 的实验数据进行了最新的全局拟合。实验数据包括高达 13 TeV 的总横截面以及单顶和对生产的微分分布。我们还包括顶夸克宽度、电荷不对称性和顶衰变产物的偏振信息。我们提出了六维算子系数的界限，并检查了包容性测量和差分测量以及 Tevatron/LHC 数据之间的相互作用。目前所有结果都与标准模型非常吻合。
We perform an up-to-date global fit of top quark effective theory to experimental data from the Tevatron, and from LHC Runs I and II. Experimental data includes total cross-sections up to 13 TeV, as well as differential distributions, for both single top and pair production. We also include the top quark width, charge asymmetries, and polarisation information from top decay products. We present bounds on the coefficients of dimension six operators, and examine the interplay between inclusive and differential measurements, and Tevatron/LHC data. All results are currently in good agreement with the Standard Model.
