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…

Connection between the Green functions of the supersymmetric pair of Dirac Hamiltonians

Ekaterina Pozdeeva

The Sukumar theorem about the connection between the Green functions of the supersymmetric pair of the Schrödinger Hamiltonians is generalized to the case of the supersymmetric pai…

N=4 superconformal Calogero models

Anton Galajinsky, Olaf Lechtenfeld, Kirill Polovnikov

We continue the research initiated in hep-th/0607215 and apply our method of conformal automorphisms to generate various N=4 superconformal quantum many-body systems on the real li…

Path integral representations in noncommutative quantum mechanics and noncommutative version of Berezin-Marinov action

D. M. Gitman, V. G. Kupriyanov

It is known that actions of field theories on a noncommutative space-time can be written as some modified (we call them -modified) classical actions already on the commutative s…

Darboux Transformation of the Green Function for the Dirac Equation with the Generalized Potential

Ekaterina Pozdeeva

We consider the Darboux transformation of the Green functions of the regular boundary problem of the one-dimensional stationary Dirac equation. We obtained the Green functions of t…

Quantization of Donaldson-Uhlenbeck-Yau theory

S. L. Lyakhovich, A. A. Sharapov

A covariant path-integral quantization is proposed for the non-Lagrangian gauge theory described by the Donaldson-Uhlenbeck-Yau equation. The corresponding partition function is sh…

BRST approach to Lagrangian construction for fermionic higher spin fields in AdS space

I. L. Buchbinder, V. A. Krykhtin, A. A. Reshetnyak

We develop a general gauge invariant Lagrangian construction for half-integer higher spin fields in the AdS space of any dimension. Starting with formulation in terms of auxiliary…

Quartet unconstrained formulation for massless higher spin fields

I. L. Buchbinder, A. V. Galajinsky, V. A. Krykhtin

We construct simple unconstrained Lagrangian formulations for massless higher spin fields in flat space of arbitrary dimension and on anti de Sitter background. Starting from the t…
