Su (2) × Su (2) Harmonic Superspace and (4,4) Sigma Models with Torsion
نویسنده
چکیده
We review a manifestly supersymmetric off-shell formulation of a wide class of torsionful (4, 4) 2D sigma models and their massive deformations in the harmonic superspace with a double set of SU(2) harmonic variables. Sigma models with both commuting and non-commuting left and right complex structures are treated.

Harmonic superspace geometry of (4,4) supersymmetric sigma models with torsion.
Starting from the dual action of (4, 4) 2D twisted multiplets in the harmonic superspace with two independent sets of SU(2) harmonic variables, we present its generalization which hopefully provides an off-shell description of general (4, 4) supersymmetric sigma models with torsion. Like the action of the torsionless (4, 4) hyper-Kähler sigma models in the standard harmonic superspace, it is ch...
متن کامل1 99 4 BONN - TH - 94 - 02 hep - th / xxxxxx April 1994 Sigma models in ( 4 , 4 ) harmonic superspace
We define basics of (4, 4) 2D harmonic superspace with two independent sets of SU (2) harmonic variables and apply it to construct new superfield actions of (4, 4) supersymmetric two-dimensional sigma models with torsion and mutually commuting left and right complex structures, as well as of their massive deformations. We show that the generic off-shell sigma model action is the general action ...
متن کاملHarmonic Superspace: Some New Trends
We give a brief account of two recent applications of the harmonic superspace method: (i) an off-shell description of torsionful (4, 4) supersymmetric 2D sigma models in the framework of SU(2) × SU(2) harmonic superspace and (ii) the harmonic superspace formulation of “small” N = 4 SU(2) superconformal algebra and the related super KdV hierarchy.
متن کاملApril 1996 MORE ON ( 4 , 4 ) SUPERMULTIPLETS IN SU ( 2 ) × SU ( 2 ) HARMONIC SUPERSPACE
We define the SU (2) × SU (2) harmonic superspace analogs of tensor and non-linear (4, 4), 2D supermultiplets. They are described by constrained analytic super-fields and provide an off-shell formulation of a class of torsionful (4, 4) supersym-metric sigma models with abelian translational isometries on the bosonic target. We examine their relation to (4, 4) twisted multiplets and discuss diff...
متن کاملDIVERSITY OF OFF – SHELL TWISTED ( 4 , 4 ) MULTIPLETS IN SU ( 2 ) x SU ( 2 ) HARMONIC SUPERSPACE
We elaborate on four different types of twisted N = (4, 4) supermultiplets in the SU (2) × SU (2), 2D harmonic superspace. In the conventional N = (4, 4), 2D superspace they are described by the superfieldsˆq i a , ˆ q i a , ˆ q i a , ˆ q i a subjected to proper differential constraints, (i, i, a, a) being the doublet indices of four groups SU (2) which form the full R-symmetry group SO(4) L × ...
