Off - Shell Formulation of N = 2 Non - Linear Σ - Models
We study d = 2, N = (2, 2) non-linear σ-models in (2, 2) superspace. By analyzing the most general constraints on a superfield, we show that through an appropriate choice of coordinates, there are no other superfields than chiral, twisted chiral and semi-chiral ones. We study the resulting σ-models and we speculate on the possibility that all (2, 2) non-linear σ-models can be described using th...
متن کاملThe Quantum Geometry of N = (2, 2) Non-linear Σ-models
We consider a general N = (2, 2) non-linear σ-model in (2, 2) superspace. Depending on the details of the complex structures involved, an off-shell description can be given in terms of chiral, twisted chiral and semi-chiral superfields. Using superspace techniques, we derive the conditions the potential has to satisfy in order to be ultraviolet finite at one loop. We pay particular attention to...
متن کاملGauging N=2 Supersymmetric Non-Linear σ-Models in the Atiyah-Ward Space-Time
We build up a class of N=2 supersymmetric non-linear σ-models in an N=1 superspace based on the Atiyah-Ward space-time of (2+2)–signature metric. We also discuss the gauging of isometries of the associated hyper-Kählerian target spaces and present the resulting gauge-covariant supersymmetric action functional. e-mail address: [email protected] e-mail address: [email protected]
متن کاملOff - shell N = 2 tensor supermultiplets
A multiplet calculus is presented for an arbitrary number n of N = 2 tensor supermultiplets. For rigid supersymmetry the known couplings are reproduced. In the superconformal case the target spaces parametrized by the scalar fields are cones over (3n − 1)-dimensional spaces encoded in homogeneous SU(2) invariant potentials, subject to certain constraints. The coupling to conformal supergravity ...
متن کاملDeformations with maximal supersymmetries part 2: off-shell formulation
Continuing our exploration of maximally supersymmetric gauge theories (MSYM) deformed by higher dimensional operators, in this paper we consider an offshell approach based on pure spinor superspace and focus on constructing supersymmetric deformations beyond the first order. In particular, we give a construction of the BatalinVilkovisky action of an all-order non-Abelian Born-Infeld deformation...
