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

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