$N = 2$ Higher Spins by Harmonic Superspace Methods

Evgeny Ivanov

Harmonic $N = 2$ superspace was discovered in 1984 as the powerful tool of the geometric superfield off-shell description of $N = 2, 4 D$ supersymmetric field theories wit…

$N = 2$ AdS hypermultiplets in harmonic superspace

Evgeny Ivanov, Nikita Zaigraev

We present the harmonic superspace formulation of $N = 2$ hypermultiplet in AdS $_{4}$ background, starting from the proper realization of $4 D, N = 2$ superconformal g…

Towards $N = 2$ higher-spin supergravity

Ioseph Buchbinder, Evgeny Ivanov, Nikita Zaigraev

We review the superfield formulation of $N = 2$ higher-spin supergravity theory in harmonic superspace. The analysis of both the hypermultiplet higher-spin supersymmetries…

$N = 2$ superconformal gravitino in harmonic superspace

Evgeny Ivanov, Nikita Zaigraev

We present the harmonic superspace formulation of $N = 2$ gravitino multiplet, the simplest $N = 2$ half-integer spin gauge supermultiplet. It is shown that, quite…
