Quasicomplex N = 2 , d = 1 Supersymmetric Sigma Models
We derive and discuss a new type of N = 2 supersymmetric quantum mechanical sigma models which appear when the superfield action of the (1,2,1) multiplets is modified by adding an imaginary antisymmetric tensor to the target space metric, thus completing the latter to a non-symmetric Hermitian metric. These models are not equivalent to the standard de Rham sigma models, but are related to them ...
متن کاملManifestly Supersymmetric Effective Lagrangians on BPS Solitons
A systematic method to obtain the effective Lagrangian on the BPS background in supersymmetric gauge theories is worked out, taking domain walls and vortices as concrete examples. The Lagrangian in terms of the superfields with four preserved supercharges is expanded in powers of the slow-movement parameter λ. The expansion gives the superfield form of the BPS equations at O(λ0), and all the fl...
متن کاملNew symmetries of supersymmetric effective Lagrangians.
We consider the structure of effective lagrangians describing the low-energy dynamics of supersymmetric theories in which a global symmetry G is spontaneously broken to a subgroup H while supersymmetry is unbroken. In accordance with the supersymmetric Goldstone theorem, these lagrangians contain Nambu–Goldstone superfields associated with a coset space G/Ĥ, where G is the complexification of G...
متن کاملThe Geometry of Supersymmetric D = 2 Nonlinear Sigma Models
This paper will consider supersymmetric nonlinear sigma models in two space-time dimensions. First, the rich variety of possible supersymmetries in two dimensions will be discussed. Next, a slight detour into some complex geometry will be taken to gather some useful definitions and results. Finally, it will be shown that requiring the sigma model to have extended supersymmetry imposes various g...
متن کاملSupersymmetric Nonlinear Sigma - Models in 4 D , N = 1 Superspace
Using 4D, N = 1 superfield techniques, a discussion of the 6D sigmamodel possessing simple supersymmetry is given. Two such approaches are described. Foremost it is shown that the simplest and most transparent description arises by use of a doublet of chiral scalar superfields for each 6D hypermultiplet. A second description that is most directly related to projective superspace is also present...
