论文摘要
对超宪法场理论的准确边际变形的研究是一个主题，由于其丰富的特性而受到了相当大的关注。我们研究了$ \ Mathcal {n} = 2 $保留3D $ s $ fold scfts的边缘运算符。考虑了两个此类理论的家族：一个是通过衡量$ t（u（2））$和$ t（u（3））$理论的对角性风味对称性来构建的，而另一个是通过衡量$ t^{[2,1^2]} _ {[2,1^2] _ {[2,1^2] $ the $ t^{[2,1^2]} $ t^{[2,1^2] _ {[2,1^2] $理论的对角线风味对称的。在这两个家庭中，每个量规组都可以打开Chern-Simons级别，并将各种数量的超多年级与每个理论相结合。精确边缘运算符的详细分析以及超符号指数使我们能够确定在红外线中的超对称性是否增强，并推断相应的SCFT的超对称性量。
The study of exactly marginal deformations of superconformal field theories is a topic that has received considerable attention due to their rich properties. We investigate the $\mathcal{N}=2$ preserving exactly marginal operators of 3d $S$-fold SCFTs. Two families of such theories are considered: one is constructed by gauging the diagonal flavour symmetry of the $T(U(2))$ and $T(U(3))$ theories, and the other by gauging the diagonal flavour symmetry of the $T^{[2,1^2]}_{[2,1^2]}(SU(4))$ theory. In both families, it is possible to turn on a Chern--Simons level for each gauge group and to couple to each theory various numbers of hypermultiplets. The detailed analysis of the exactly marginal operators, along with the superconformal indices, allows us to determine whether supersymmetry gets enhanced in the infrared and to deduce the amount of supersymmetry of the corresponding SCFT.
