摘要：

利用Landau规范固定条件，在Wess-Zumino规范下分析了含有局域复合算符$A^2$的$\mathcal{N}=1$ Super Yang-Mills理论.由于该理论的超对称结构，还引入了与$A^2$的SUSY变式有关的两个复合算子$A_μγ_μλ$和$\barλλ$.一个BRST不变的行动，包含所有这些运营商。然后，通过代数重整化装置提供了所得到的理论的乘法重整化的全阶证明。然而，由于Wess-Zumino规范场超对称性的非线性实现，规范场的重整化因子与胶子的重整化因子不同。

英文摘要：

The $\mathcal{N}=1$ Super Yang-Mills theory in the presence of the local composite operator $A^2$ is analyzed in the Wess-Zumino gauge by employing the Landau gauge fixing condition. Due to the superymmetric structure of the theory, two more composite operators, $A_μγ_μλ$ and $\barλλ$, related to the susy variations of $A^2$ are also introduced. A BRST invariant action containing all these operators is obtained. An all order proof of the multiplicative renormalizability of the resulting theory is then provided by means of the algebraic renormalization setup. Though, due to the non-linear realization of the supersymmetry in the Wess-Zumino gauge, the renormalization factor of the gauge field turns out to be different from that of the gluino.
