论文摘要
在标准模型有效场理论中，我们使用壳体S-Matrix和形式因素来计算高维操作员的异常维度。我们发现，在许多情况下，通过使用壳方法使这些计算变得简单。我们首先计算在一环下发生的尺寸六个操作员对算子的异常尺寸的贡献。然后，我们使用这种强大的方法计算了相应的一环贡献的两循环异常维度。
We use the on-shell S-matrix and form factors to compute anomalous dimensions of higher dimension operators in the Standard Model Effective Field Theory. We find that in many instances, these computations are made simple by using the on-shell method. We first compute contributions to anomalous dimensions of operators at dimension-six that arise at one-loop. Then we calculate two-loop anomalous dimensions for which the corresponding one-loop contribution is absent, using this powerful method.
