论文摘要
我们用n个全局非线性超对称性分析了标准的费米克4D Volkov-Akulov作用。我们发现，系统的固定点由有效电位描述，用两个复合的真实标量场编写，该字段接近较大的N极限中的确切量子有效电位。我们确定了至少两个固定点的存在，一个代表原始的超对称性断裂构型，另一个代表与戈德斯蒂诺凝结相对应的一个，其中一个对应于戈德斯蒂诺的凝结，在深处IR中恢复了超对称性。
We analyze the standard fermionic 4D Volkov-Akulov action with N global non-linear supersymmetries. We find that the stationary points of the system are described by an effective potential, written in terms of two composite real scalar fields, which approaches the exact quantum effective potential in the large N limit. We identify the existence of at least two stationary points, one representing the original supersymmetry breaking configuration and the other one corresponding to goldstino condensation, where supersymmetry is restored in the deep IR.
