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…

superconformal gravitino in harmonic superspace
Evgeny Ivanov, Nikita Zaigraev
We present the harmonic superspace formulation of gravitino multiplet, the simplest half-integer spin gauge supermultiplet. It is shown that, quite…
