超对称规范理论的最新发现对于我们对 QCD 和一般场论的理解具有重大意义。讨论了N=1超对称QCD（SQCD）的相位，并强调了非超对称QCD中类似相位的可能性。描述了 SQCD 中的对偶性如何将许多先前已知的对偶变换联系起来，这些变换被认为是不同的，包括 N = 4 超对称规范理论的 Olive-Montonen 对偶性和 (S)QCD 中的 quarkhadron 对偶性。解释了 Olive-Montonen 对偶性与 (S)QCD 限制弦之间的联系，其中通过非阿贝尔单极子凝聚（广义的对偶迈斯纳效应）进行限制的图景明确出现。在这张图中，与之前的不同，约束通量管携带正确的 ZN 离散电荷。提出了许多可以使用晶格规范理论进行的这些主题的研究。 *) 在日本京都 YKIS’97 上发表的演讲。 ***) 电子邮件地址：strassler@ias.edu 1 使用 PTPTEX.sty 排版
Recent discoveries in supersymmetric gauge theories have significant implications for our understanding for QCD and of field theory in general. The phases of N = 1 supersymmetric QCD (SQCD) are discussed, and the possibility of similar phases in non-supersymmetric QCD is emphasized. It is described how duality in SQCD links many previously known duality transformations that were thought to be distinct, including Olive-Montonen duality of N = 4 supersymmetric gauge theory and quarkhadron duality in (S)QCD. A link between Olive-Montonen duality and the confining strings of (S)QCD is explained, in which a picture of confinement via non-abelian monopole condensation — a generalized dual Meissner effect — emerges explicitly. In this picture, unlike previous ones, the confining flux tubes carry the correct ZN discrete charges. A number of studies of these subjects, which could be carried out using lattice gauge theory, are proposed. ∗) Talk given at YKIS’97, Kyoto, Japan. ∗∗) E-mail address: strassler@ias.edu 1 typeset using PTPTEX.sty
