Title: One-dimensional subsectors in three-dimensional supersymmetric gauge theories
Abstract: I will present some recent developments in supersymmetric gauge theories in three dimensions. I will discuss two classes of supersymmetric observable, invariant under certain supercharges available only with N≥4 supersymmetry. The first is a set of local operators whose correlators on a line do not depend on the position. They provide a tractable non-trivial subsector containing information on the whole theory. In particular, I will illustrate a Ward identity that relates the topological sector to some integrated correlators associated with real mass deformations. The second is the so-called latitude Wilson loop. I will propose a localization formula and exploit the result to argue a novel duality among loop operators.
