我们回顾了目前对超对称规范理论的非微扰特征的理解，这些特征被认为决定了其基态（真空）的性质。详细讨论了各种各样的理论：纯杨-米尔斯理论、有质量或无质量实物质场的理论、手性物质的理论，无论是对于 SU(N) 还是对于一般紧规范群的情况（例如 E8）。根据所考虑的理论的一些一般特征，会出现各种（也许）意想不到的现象。其中包括（微扰建立的）非重正化定理的崩溃、在一定限度内失控真空的出现、某些手性理论中超对称性本身的自发动力学破缺。在整个报告中，我们将自己限制在限制图像瞬子方法上，偶尔用来自手性和超对称 Ward-Takahashi 恒等式的信息对其进行补充。我们将我们的结果与之前通过有效的拉格朗日方法提出的结果进行比较，并简单地与希格斯图片中其他小组获得的结果进行比较。
We review our present understanding of those non-perturbative features of supersymmetric gauge theories that are believed to determine the properties of their ground states (vacua). A wide variety of theories is discussed in detail: pure Yang-Mills, theories with massive or massless real matter fields, theories with chiral matter, both for SU(N) and for the case of a general compact gauge group (as for instance E8). Depending on some general features of the theory under consideration, various (perhaps) unexpected phenomena are shown to occur. Among these the breakdown of the (perturbatively established) non-renormalization theorem, the occurrence of runaway vacua in certain limits, the spontaneous dynamical breaking of supersymmetry itself in some chiral theories. Throughout the report we restrict ourselves to the confining picture instanton method, occasionally complementing it with the information coming from chiral and supersymmetric Ward-Takahashi identities. We compare our results with the ones suggested earlier by effective Lagrangian methods and, only briefly, with those obtained by other groups in the Higgs picture.
