N = 4 Supersymmetric Mechanics in Harmonic Superspace
We define N =4, d=1 harmonic superspace HR 1+2|4 with an SU(2)/U(1) harmonic part, SU(2) being one of two factors of the R-symmetry group SU(2)× SU(2) of N =4, d=1 Poincaré supersymmetry. We reformulate, in this new setting, the models of N =4 supersymmetric quantum mechanics associated with the off-shell mul-tiplets (3, 4, 1) and (4, 4, 0). The latter admit a natural description as constrained...
متن کاملN , p , q ) Harmonic Superspace G . G . Hartwell and P .
A family of harmonic superspaces associated with four-dimensional Minkowski spacetime is described. Applications are given to free mass-less supermultiplets, invariant integrals and super Yang-Mills. The generalisation to curved spacetimes is given with emphasis on confor-mal supergravities.
متن کاملHarmonic 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 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...
