梯度流[1-5]给出了一种以正则化无关的方式构造重正化复合算子的通用方法。通过采用这种方法，作者的参考文献。[6-9]得到了晶格正则化破坏相关对称性时晶格上Noether电流的表达式。我们将同样的方法应用于与超对称性相关的Noether电流，即，超级电流考虑4DN= 1超杨-米尔斯理论，计算了Wess-Zumino规范中单圈能级的重整化超流.然后，我们用流动规范场和流动的高吉诺场来重新表达这种超电流[10]。
The gradient flow [1–5] gives rise to a versatile method to construct renor-malized composite operators in a regularization-independent manner. By adopting this method, the authors of Refs. [6–9] obtained the expression of Noether currents on the lattice in the cases where the associated symmetries are broken by lattice regularization. We apply the same method to the Noether current associated with supersymmetry, i.e., the supercurrent. We consider the 4DN= 1 super Yang–Mills theory and calculate the renormalized supercurrent in the one-loop level in the Wess–Zumino gauge. We then re-express this supercurrent in terms of the flowed gauge and flowed gaugino fields [10].
