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…
Hierarchy of N=8 Mechanics Models
Evgeny Ivanov, Olaf Lechtenfeld, Anton Sutulin
Using the N=4 superspace approach in one dimension (time), we construct general N=8 supersymmetric mechanics actions for the multiplets (b,8,8-b) classified in hep-th/0406015, with…
Nonlinear Realizations in Tensorial Superspaces and Higher Spins
Evgeny Ivanov
In the first part of the talk I report on surprising relations between higher spin (HS) theory and nonlinear realizations of the supergroup OSp(1|8), a minimal superconformal exten…
Planar Super-Landau Models Revisited
Thomas Curtright, Evgeny Ivanov, Luca Mezincescu +1
We use the methods of PT-symmetric quantum theory to find a one-parameter family of ISU(1|1)-invariant planar super-Landau models with positive norm, uncovering an `accidental', an…
