Supersymmetric Chern-Simons models in harmonic superspaces
B. M. Zupnik
We review harmonic superspaces of the D=3, N=3 and 4 supersymmetries and gauge models in these superspaces. Superspaces of the D=3, N=5 supersymmetry use harmonic coordinates of th…
Chern-Simons D=3, N=6 superfield theory
B. M. Zupnik
We construct the D=3, N=5 harmonic superspace using the SO(5)/U(1) x U(1) harmonics. Three gauge harmonic superfields satisfy the off-shell constraints of the Grassmann and harmoni…
Gauge theory in deformed N=(1,1) superspace
I. L. Buchbinder, E. A. Ivanov, O. Lechtenfeld +2
We review the non-anticommutative Q-deformations of N=(1,1) supersymmetric theories in four-dimensional Euclidean harmonic superspace. These deformations preserve chirality and har…
Gauge Model in D=3, N=5 Harmonic Superspace
B. M. Zupnik
We construct the Grassmann-analytic gauge superfields in D=3, N=5 harmonic superspace using the SO(5)/U(1)xU(1) harmonics. These gauge N=5 superfields contain an infinite number of…
Non-anticommutative N=(1,1) Euclidean Superspace
E. Ivanov, O. Lechtenfeld, B. Zupnik
We study deformations of four-dimensional N=(1,1)Euclidean superspace induced by non-anticommuting fermionic coordinates. We essentially use the harmonic superspace approach and co…
Invariance of interaction terms in new representation of self-dual electrodynamics
B. M. Zupnik
A new representation of Lagrangians of 4D nonlinear electrodynamics is considered. In this new formulation, in parallel with the standard Maxwell field strength F, an auxiliary bis…
