Linearized conformal supergravity in the harmonic approach
Evgeny Ivanov, Nikita Zaigraev
Using the harmonic superspace approach, we construct the superconformal harmonic action for Weyl supermultiplet. The fundamental objects of the theory are unconstra…
Supersymmetry at BLTP: Recent Progress in Two Directions
I. L. Buchbinder, E. A. Ivanov
Ten years ago, in a paper \cite{60}, a brief historical survey of the research activity in the Sector ``Supersymmetry'' at the Bogoliubov Laboratory of Theoretical Physics (BLTP) f…
Off-shell invariants of linearized supergravity in the harmonic approach
Evgeny Ivanov, Nikita Zaigraev
Using the harmonic superspace approach, we construct, at the linearized level, supersymmetric curvatures generalizing scalar curvature, Ricci curvature and Weyl ten…
Higher Spins by Harmonic Superspace Methods
Evgeny Ivanov
Harmonic superspace was discovered in 1984 as the powerful tool of the geometric superfield off-shell description of supersymmetric field theories wit…
AdS hypermultiplets in harmonic superspace
Evgeny Ivanov, Nikita Zaigraev
We present the harmonic superspace formulation of hypermultiplet in AdS background, starting from the proper realization of superconformal g…
Towards higher-spin supergravity
Ioseph Buchbinder, Evgeny Ivanov, Nikita Zaigraev
We review the superfield formulation of higher-spin supergravity theory in harmonic superspace. The analysis of both the hypermultiplet higher-spin supersymmetries…
