Description
I will discuss a new exact formula for supersymmetric correlation functions of gauged linear sigma models (GLSM) with $\mathcal{N}=(2,2)$ supersymmetry on the two-sphere with a twist. More precisely, the $S^2$ supersymmetric background is an ``Omega-background'' which generalizes the familiar A-twist. The formula simplifies previous results and leads to new results for non-Abelian gauge theories. It provides an interesting new tool to study strongly coupled 2d supersymmetric gauge theories with matter.
