从微观拉格朗日模型出发,提出了一种计算超对称广义傅里叶变换低能非微扰性质的方法。该方法依赖于协变超对称费曼图技术,适应于低能量,和重整化群改进的微扰理论。我们应用该方法计算了= 1 SU(2)SYM中的胶球超势,得到了Veneziano-Yankielowicz型势.
A method for computing the low-energy non-perturbative properties of SUSY GFT, starting from the microscopic lagrangian model, is presented. The method relies on covariant SUSY Feynman graph techniques, adapted to low energy, and Renormalization-Group-improved perturbation theory. We apply the method to calculate the glueball superpotential in = 1 SU(2) SYM and obtain a potential of the Veneziano-Yankielowicz type.
