论文摘要
我们探讨了重量法化组（RG）效应对LHC测量的标准模型有效现场理论（SMEFT）解释的影响。我们将RG运行和混合Wilson系数从SMEFT中的一环异常尺寸矩阵中获得，以进入蒙特卡洛发生器。这使得以不同尺度为特征的全局拟合观测值始终预测并组合。作为展示，我们研究了RG在强耦合中运行的影响对$ t \ bar t $生产横截面和差分分布的SMEFT预测，以及从当前LHC数据中获得的Wilson系数的界限。
We explore the impact of Renormalisation Group (RG) effects in the Standard Model Effective Field Theory (SMEFT) interpretations of LHC measurements. We implement the RG running and mixing for the Wilson coefficients as obtained from the one-loop anomalous dimension matrix in the SMEFT into a Monte Carlo generator. This allows to consistently predict and combine in global fits collider observables characterised by different scales. As a showcase, we examine the impact of RG running in the strong coupling on the SMEFT predictions for $t \bar t$ production cross sections and differential distributions as well as on the bounds on the Wilson coefficients that can be obtained from current LHC data.
