Goldstone-type superfields and partial spontaneous breaking of D=3, N=2 supersymmetry

We consider the modified superfield constraints with constant terms for the D = 3, N = 2 Goldstone-Maxwell gauge multiplet which contains Goldstone fe rmions, real scalar and vector fields. The partial spontaneous breaking N = 2 --> N = 1 is possible for the non-minimal self-interaction of this modif ied gauge superfield including the linear Fayet-Iliopoulos term. The dual d escription of the partial breaking in the model of the self-interacting Gol dstone chiral superfield is also discussed. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
