Non-anticommutative deformation of N=(1,1) hypermultiplets
Evgeny Ivanov, Olaf Lechtenfeld, Boris Zupnik
We study the SO(4)xSU(2) invariant and N=(1,0) supersymmetry-preserving nilpotent (non-anticommutative) Moyal deformation of hypermultiplets interacting with an abelian gauge multi…
Non-Anticommutative Deformations of N=(1,1) Supersymmetric Theories
E. A. Ivanov, B. M. Zupnik
We discuss chirality-preserving nilpotent deformations of four-dimensional N=(1,1) Euclidean harmonic superspace and their implications in N=(1,1) supersymmetric gauge and hypermul…
Non-anticommutative chiral singlet deformation of N=(1,1) gauge theory
S. Ferrara, E. Ivanov, O. Lechtenfeld +2
We study the SO(4)x SU(2) invariant Q-deformation of Euclidean N=(1,1) gauge theories in the harmonic superspace formulation. This deformation preserves chirality and Grassmann har…
A Super-Flag Landau Model
Evgeny Ivanov, Luca Mezincescu, Paul K. Townsend
We consider the quantum mechanics of a particle on the coset superspace , which is a super-flag manifold with `body'. By incorporat…
Scale Invariant Low-Energy Effective Action in N=3 SYM Theory
I. L. Buchbinder, E. A. Ivanov, I. B. Samsonov +1
Using the harmonic superspace approach we study the problem of low-energy effective action in N=3 SYM theory. The candidate effective action is a scale and γ_5-invariant functional…
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…
