论文摘要
提出了四维n = 1上对称QCD（SQCD）的超对称梯度流。流程方程在Wess-Zumino仪表的超级场和组件字段中给出。为每个仪表和物质多重组定义了超场流程。添加量规固定，组件场流程方程以量规协变方式在Wess-Zumino仪表中定义。我们发现后一个方程在某种意义上是超对称的，从流动时间衍生物的换向器和超对称转换的换向器消失到量规变换。我们还通过使用超对称阳米尔（SYM）动作的梯度，而不是使用SQCD动作来定义规格多重流程来讨论简化的流动。
A supersymmetric gradient flow for four-dimensional N=1 supersymmetric QCD (SQCD) is proposed. The flow equation is given in both the superfield and component fields of the Wess-Zumino gauge. The superfield flow equation is defined for each of the gauge and matter multiplets individually. Adding a gauge fixing, the component-field flow equation is defined in the Wess-Zumino gauge in a gauge covariant manner. We find that the latter equation is supersymmetric in a sense that the commutator of the flow time derivative and the supersymmetry transformation vanishes up to a gauge transformation. We also discuss a simplified flow by using the gradient of supersymmetric Yang-Mills (SYM) action instead of using SQCD action to define a gauge multiplet flow.
