Abstract

Wegive a physical interpretation for the analytic continuation of the partitionfunction of superconformal SU(2) N = 2 gauge theory on the four-sphere to all values ofthe Yang-Mills coupling. We show that a well-motivated 2d construction associates twodimensional unstable instantons to the 4d complex saddles which appear as singularitiesin the integrand of the supersymmetric localization expression. The construction is basedon the chiral algebra subsector, and aligns with. the alternative Higgs branch localization
