DIVERSITY 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 × ...
متن کاملN = ( 4 , 4 ) Twisted Multiplets in N = ( 2 , 2 ) Superspace
We describe four different types of the N =(4, 4) twisted supermultiplets in two-dimensional N =(2, 2) superspace R (1,1|2,2). All these multiplets are presented by a pair of chiral and twisted chiral superfields and differ in the transformation properties under an extra hidden N =(2, 2) supersymmetry. The sigma model N =(2, 2) superfield Lagrangians for each type of the N =(4, 4) twisted super...
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 کاملGauge Model with Hypermultiplets in Harmonic Superspace
We provide a manifestly N = 2 supersymmetric formulation of the N = 2 U(Nc) gauge model constructed in terms of N = 1 superfields in hep-th/0409060. The model is composed of N = 2 vector multiplets in harmonic superspace and can be viewed as the N = 2 U(Nc) Yang-Mills effective action equipped with the electric and magnetic Fayet-Iliopoulos terms. We generalize this gauge model to an N = 2 U(Nc...
متن کاملIN SU ( 2 ) xSU ( 2 ) HARMONIC SUPERSPACE
The N =8 , 1D analytic bi-harmonic superspace is shown to provide a natural setting for N =8 supersymmetric mechanics associated with the off-shell multiplet (4, 8, 4). The latter is described by an analytic superfield q 1,1 , and we construct the general superfield and component actions for any number of such multiplets. The set of transformations preserving the flat superspace constraints on ...
