5 SU(2) theory with one flavor

Our next task is to study 𝒩=2 supersymmetric SU(2) gauge theory with one hypermultiplet in the doublet representation. This is often called the SU(2) theory with one flavor, or more simply Nf = 1. We will see that all the methods employed in the last section are readily adapted to this theory, too. We again follow the presentation of the original paper [3], but we use the Seiberg-Witten curve in a form more suitable for the generalization later. Appendix C of [48] is a good source where many different forms of the Seiberg-Witten curves of SU(2) theories are summarized.
