Higher Spins in Harmonic Superspace (2306.10401v3)

Published 17 Jun 2023 in hep-th, math-ph, and math.MP

Abstract: We report on a recent progress in constructing off-shell ${\cal N}=2, 4D$ 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 $\omega$ superfield is presented. It involves both cubic and quartic vertices.
