A bstractWe study the correspondence between four-dimensional supersymmetric gauge theories and two-dimensional conformal field theories in the case of $ \mathcal{N}={2^{*}} $ gauge theory. We emphasize the genus expansion on the gauge theory side, as obtained via geometric engineering from the topological string. This point of view uncovers modular properties of the one-point conformal block on a torus with complexified intermediate momenta: in the large intermediate weight limit, it is a… CONTINUE READING
