Microscopic- versus Effective Coupling in N=2 Yang-Mills With Four Flavours
arXiv:hep-th/9910015 · doi:10.1016/S0370-2693(00)00338-5
Abstract
We determine the instanton corrections to the effective coupling in SU(2), N=2 Yang-Mills theory with four flavours to all orders. Our analysis uses the S(2,Z)-invariant curve and the two instanton contribution obtained earlier to fix the higher order contributions uniquely.
