我们研究基于 3 代数的超共形陈-西蒙斯物质理论的边缘变形。为此,我们引入了相关三乘积的概念,它捕获了 BLG 和 ABJM 模型超势的非常普遍的规范不变变形。我们还考虑保留 N=2 超对称性的共形多迹变形。然后,我们使用 N=2 超图技术来计算这些变形的二环 beta 函数。除了确认 BLG 和 ABJM 模型的共形不变性之外,我们还验证了最近提出的 ABJM 模型的 β 变形确实与我们正在考虑的阶次无关。
We study marginal deformations of superconformal Chern–Simons matter theories that are based on 3-algebras. For this, we introduce the notion of an associated 3-product, which captures very general gauge invariant deformations of the superpotentials of the BLG and ABJM models. We also consider conformal multi-trace deformations preserving N=2 supersymmetry. We then use N=2 supergraph techniques to compute the two-loop beta functions of these deformations. Besides confirming conformal invariance of both the BLG and ABJM models, we also verify that the recently proposed β-deformations of the ABJM model are indeed marginal to the order we are considering.
