Partial spontaneous breaking of the three-dimensional N = 2 supersymmetry

The superfield models with partial spontaneous breaking of the global D 3, N = 2 supersymmetry are discussed. The Abelian gauge model describes low-energy interactions of the substantial scalar field with three-dimensional vector and fermion fields. The new Goldstone-Maxwell representation of the 3D gauge field is introduced and the possibility of the partial spontaneous violation of the N = 2 → N = 1 for a nonminimal self-action of this modified gauge superfield is proved. The dual description of partial violation in the model of the Goldstone self-acting chiral superfield is also considered. These models have constant vacuum solutions and describe correspondingly the N = 1 interactions of the Goldstone multiplets
