Harmonic Superspace: Some New Trends

نویسنده

Evgeny A. Ivanov

چکیده

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.

1 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 ...

Effective Action of N = 2 Supersymmetric Field Theories in Harmonic Superspace Approach

The paper is a brief review of the works devoted to problem of effective action in N = 2 super Yang-Mills theories in harmonic superspace approach. The formulation of N = 2 superfield models in harmonic superspace is discussed, background field method for N = 2 super Yang-Mills theory is constructed and general structure of effective action in harmonic superspace is investigated. It is shown ho...

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...

The Mini - Superspace Limit of the Sl ( 2 , C ) / Su ( 2 ) - Wznw Model

Many qualitatively new features of WZNW models associated to noncompact cosets are due to zero modes with continuous spectrum. Insight may be gained by reducing the theory to its zero-mode sector, the mini-superspace limit. This will be discussed in some detail for the example of SL(2,C)/SU(2)-WZNW model. The mini-superspace limit of this model can be formulated as baby-CFT. Spectrum, structure...
