supersymmetric σ - models
Supersymmetric non–linear σ–models are described by a field dependent Kähler metric determining the kinetic terms. In general it is not guaranteed that this metric is always invertible. Our aim is to investigate the symmetry structure of supersymmetric models in four dimensional space-time in which metric singularities occur. For this purpose we study a simple anomaly-free extension of the supe...
متن کاملThe Geometry of Supersymmetric Σ-models
We review non-linear σ-models with (2,1) and (2,2) supersymmetry. We focus on off-shell closure of the supersymmetry algebra and give a complete list of (2, 2) superfields. We provide evidence to support the conjecture that all N = (2, 2) non-linear σ-models can be described by these fields. This in its turn leads to interesting consequences about the geometry of the target manifolds. One immed...
متن کاملGeometry and Duality in Supersymmetric Σ - Models
The Supersymmetric Dual Sigma Model (SDSM) is a local field theory introduced to be nonlocally equivalent to the Supersymmetric Chiral nonlinear σ-Model (SCM), this dual equivalence being proven by explicit canonical transformation in tangent space. This model is here reconstructed in superspace and identified as a chiral-entwined supersymmetrization of the Dual Sigma Model (DSM). This analysis...
متن کاملSupersymmetric σ-Models on Toric Varieties: A Test Case
In this letter we study supersymmetric σ-models on toric varieties. These manifolds are generalizations of P manifolds. We examine here σ-models, viewed as gauged linear σ-models, on one of the simplest such manifold, the blow-up of P(2,1,1), and determine their properties using the techniques of topological-antitopological fusion. We find that the model contains solitons which become massless ...
متن کاملMatter coupling and anomaly cancellation in supersymmetric σ - models
Generalized matter couplings to four-dimensional supersymmetric sigma models on general Kähler manifolds are presented, preserving all holomorphic symmetries. Our generalization allows assignment of arbitrary U(1) charges to additional matter fermions, in all representations of (the holomorphic part of) the isometry group. This can be used to eliminate unwanted γ5 anomalies, in particular for t...
