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…
New representation for Lagrangians of self-dual nonlinear electrodynamics
E. A. Ivanov, B. M. Zupnik
We elaborate on a new representation of Lagrangians of 4D nonlinear electrodynamics including the Born-Infeld theory as a particular case. In this new formulation, in parallel with…
Geometry of solutions of N=2 SYM-theory in harmonic superspace
B. M. Zupnik
In harmonic superspace, the classical equations of motion of supersymmetric Yang-Mills theory for Minkowski and Euclidean spaces are analyzed. We study dual superfield r…
Short harmonic superfields and light-cone gauge in super-Yang-Mills equations
B. M. Zupnik
We analyze the superfield equations of the 4-dimensional N=2 and N=4 SYM-theories using light-cone gauge conditions and the harmonic-superspace approach. The harmonic superfield eq…
Solving N=3 super-Yang-Mills equations in harmonic superspace
B. M. Zupnik
We analyze the superfield constraints of the D=4, N=3 SYM-theory using light-cone gauge conditions. The SU(3)/U(1)xU(1) harmonic variables are interpreted as auxiliary spectral par…
