### Abstract

We perform a model-independent analysis of the spontaneously broken phase of an SU (2) × U (1) supersymmetric gauge theory, by using a non-linear parametrization of the Goldstone sector of the theory. The non-linear variables correspond to an SL(2, C) superfield matrix in terms of which a non-linear lagrangian can be constructed, and the pattern of supersymmetry breaking investigated. The supersymmetric order parameter is the VEV of the neutral pseudo-Goldstone boson. Some applications of this technique are considered, in relation to the minimal supersymmetric standard model, and to determine the g-2 of the W-bosons in the limit of large top mass.
