It is important to understand moduli spaces of vacua of four dimensional (4d) N = 2 su-perconformal field theories (SCFTs). fika login An N = 2 SCFT could have a Coulomb branch and a Higgs branch The low energy effective theory on the Coulomb branch is solved by finding a Seiberg-Witten geometry Almost every nontrivial 4d N = 2 SCFT has a Coulomb branch,
