论文摘要
我们解决了一个长期以来的问题，即ABJM理论是否有Wilson Loop操作员保留八个增压（SO 1/3 BP）。我们提出了这样的威尔逊循环，该循环由大型超级座椅制成，结合了两个1/2 BPS Wilson Loops。我们研究了操作员插入其中的光谱，包括位移操作员和其他几个，并研究其相关功能。在这种情况下，出现的另一个自然结构是Wilson循环，具有交替的超级连接。这相当于沿着循环包含“变化的算子”，类似于离散的尖端。此插入是拓扑结构，并保留了两个增压。我们研究了该操作员的多重组以及如何使用它来引入更多操作员。我们还构建了由边缘缺陷算子产生的缺陷保形流形。
We address a longstanding question of whether ABJM theory has Wilson loop operators preserving eight supercharges (so 1/3 BPS). We present such Wilson loops made of a large supermatrix combining two 1/2 BPS Wilson loops. We study the spectrum of operator insertions into them including the displacement operator and several others and study their correlation functions. Another natural construction arising in this context are Wilson loops with alternating superconnections. This amounts to including "defect changing operators" along the loop, similar to a discrete cusp. This insertion is topological and preserves two supercharges. We study the multiplet of this operator and how it can be used to introduce further operators. We also construct the defect conformal manifold arising from marginal defect operators.
