Higher Spins in Harmonic Superspace
Abstract
We report on a recent progress in constructing off-shell N=2, 4D supersymmetric integer higher-spin theory in terms of unconstrained harmonic analytic gauge superfields and their cubic interaction with the matter hypermultiplets. For even superspins a new equivalent representation of the hypermultiplet couplings in terms of analytic ω superfield is presented. It involves both cubic and quartic vertices.
