Abstract: 這篇論文總結了如何運用Seiber-Witten 曲線定義N=2 超對稱量子場論真空態上的低能量有效理論,同時分析在形變之下代表著不同真空的模空間構造如何變化。為了介紹基礎的概念,引進SU(2)規範場論的例子來描述以上的分析。同時介紹了另一種從超弦理論中的F-理論中推導出N=2 超對稱規範場論的方法,以另一種角度分析真空的模空間構造,並且能找到對應其幾何構造的ADE-奇異點。這些奇異點等效上定義了局域的模空間構造,並且分類出7種對應於共形場論的奇異點。反過來以共形對稱的真空模空間來定義出秩1超對稱共形場論,並且加以自然條件來尋找出可能存在的共形場論。這些共形場論是強耦合的理論,並不持有拉格朗日量來描述其下的物理性質,微擾理論無法用於分析此種場論。僅有其味對稱性及特定的非微擾量可以被分析出來。
I study low energy theory on Coulomb branch of N=2 theory using Seiberg-Witten curves and SW differential. Various generalization of curve for rank 1 gauge theories have been found for decades. A series of non-Lagrangian interacting N=2 SCFT with ADE type global symmetry has been predicted and corresponding curves are constructed. I review on basic ingredients used to analyse N=2 SU(2) gauge theory where Seiberg-Witten curve will be introduced. I also review rank-1 Argyres-Douglas theories and string theory approach to N=2 gauge theory. Finally I will review the classification of N=2 rank 1 SCFTs using geometric constraints and relevant deformations.
