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…

Novel higher-spin supercurrents

Nikita Zaigraev

We study cubic interactions of massless integer-spin gauge supermultiplets in harmonic superspace. We construct the complete class of abelian $(\mathbf{s},\mathbf{s_…

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…

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…
