The situations in which the bulk theory is conformal and the defect inhe rits part of this symmetry -- the so-called defect conformal field theorie s (dCFTs) -- have recently received a lot of attention\, also thanks to n ew powerful methods to tackle them\, like supersymmetric localization\, in tegrability or the bootstrap. A dCFT may be deformed by turning on margina lly relevant operators\, which trigger RG flows connecting different fixed points. A natural arena where this phenomenon can be explored are 3-dimen sional Chern-Simons theories coupled to matter. These are in fact known to display a plethora of Wilson loops that can be used to define 1-dimension al dCFTs living on their contours. In this talk we 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 dimensio ns of the deforming operators\, establish g-theorems along the flows\, and also discuss the role played by cohomological anomalies and framing.\n\nB ased on: 2211.16501\, 2305.01647\, 2312.13283\, 2410.10970\n LOCATION:https://researchseminars.org/talk/NKUA-HEP/36/ END:VEVENT END:VCALENDAR
