$\mathcal{N}=2$ higher-spin theories and harmonic superspace
Abstract
A brief review of the harmonic superspace approach to the construction of supersymmetric higher spin theories is given. We define off-shell analytic harmonic gauge potentials of supersymmetric higher-spin multiplets and of superconformal higher-spin multiplets for an arbitrary integer highest spin. The component contents of these higher-spin supermultiplets are explicitly presented. We also construct their cubic couplings to the hypermultiplet. This short report summarizes the basic results of the series of published papers [1-3] as well as announces those of the forthcoming article [4].
