The Hypermultiplet in N = 2 Superspace

Abstract

Global N=2 supersymmetry in four dimensions with a Fayet-Sohnius hypermultiplet and a complex central charge is studied in N = 2 superspace. It is shown how to construct the complete expansion of the hypermultiplet with respect to the central charge. In addition the low-energy effective action is discussed and it is shown that the `kernel' of the Lagrangian only needs an integration over a `small' superspace to construct a supersymmetric action.
