Massless higher-spin supermultiplets in 5D harmonic superspace
Abstract
A bstract Off-shell actions for massless higher-spin $$ \mathcal{N}=1 $$ N = 1 supermultiplets in five dimensions (5D) are constructed in harmonic superspace in terms of unconstrained prepotentials. Cubic couplings of these supermultiplets to the q -hypermultiplet are derived. We also provide a detailed derivation of the unconstrained prepotential for the 5D Weyl supermultiplet which has been used within the conformal superspace approach to $$ \mathcal{N}=1 $$ N = 1 supergravity-matter systems.
