Description
Chern-Simons-matter theories in 3 dimensions are known to display a plethora of Wilson loops that can be used to define 1-dimensional defect conformal field theories (dCFTs) living on their contours. In this talk we propose to discuss a few examples from an intricate web of RG flows connecting the dCFTs defined on the BPS and non-BPS Wilson loops of ABJM theory. We compute the anomalous dimensions of the deforming operators, establish g-theorems along the flows, and also discuss the role played by cohomological anomalies and framing. We do this both at weak coupling in perturbation theory and at strong coupling, using the holographic duals of these operators.
