三维$\mathcal{N}=2$渔网理论中的圈算子

Loop Operators in Three-Dimensional $\mathcal{N}=2$ Fishnet Theories

Jun-bao Wu, Jia Tian, Bin Chen

摘要:

在这项工作中,我们详细研究了三维${\mathcal N}=2$渔网理论中的线算子和环算子。我们构造了至少是经典的半BPS的直线和循环算子。我们在$-1$框架下发展了一个新的正则化方案,该方案适用于一般超Chern-Simons物质理论中的费米BPS圈的研究.基于该方案,我们初始化了循环BPS圈算子真空期望值的微扰计算。我们构造了尖线算子,并计算了这些尖线算子的真空期望值,直到两圈阶。我们发现,如果不考虑广义势在$1/ε$展开式中具有双极点的事实,普适尖点反常维数为零。

英文摘要:

In this work, we study the line and loop operators in three-dimensional ${\mathcal N}=2$ fishnet theories in detail. We construct the straight line and circular loop operators which are at least classically half-BPS. We develop a new regularization scheme at frame $-1$ which is suitable for the study of the fermionic BPS loops in general super-Chern-Simons-matter theories. We initialize the perturbative computation for the vacuum expectation values of the circular BPS loop operators based on this scheme. We construct the cusped line operators as well, and compute the vacuum expectation values of these cusped line operators up to two-loop order. We find that the universal cusp anomalous dimension vanishes, if we put aside the fact that the generalized potential has a double pole in the $1/ε$ expansion.
