Clarified the role of spontaneous SUSY breaking in the superfield framework.

Provided insights into the structure of N=2 vector supermultiplets.

Abstract

The relation between a N = 2 nonlinear supersymmetric (SUSY) model and a linear SUSY (free) theory for $N = 2$ vector supermultiplet accompanying the spontaneous SUSY breaking is systematically worked out in two-dimensional superfield formulation.
