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…
Fuzzy CP(n|m) as a quantum superspace
Evgeny Ivanov, Luca Mezincescu, Paul K. Townsend
The `Chern-Simons Quantum Mechanics' of a particle on CP(n|m) is shown to yield the fuzzy descriptions of these superspaces, for which we construct the non-(anti)commuting position…
Exact N=4 Supersymmetric Low-Energy Effective Action in N=4 Super-Yang-Mills Theory
I. L. Buchbinder, E. A. Ivanov
We review a recent progress in constructing the low-energy effective action of N=4 SYM theory. This theory is formulated in terms of N=2 harmonic superfields corresponding to N=2 v…
Towards higher-N superextensions of Born-Infeld theory
E. Ivanov
We give a brief account of supersymmetric Born-Infeld theories with extended supersymmetry, including those with partially broken supersymmetry. Some latest developments in this ar…
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…
Modifying N=2 Supersymmetry via Partial Breaking
Evgeny Ivanov, Boris Zupnik
We study realization of N=2 SUSY in N=2 abelian gauge theory with electric and magnetic terms within a manifestly supersymmetric formulation. We find that after dualization of…
