Supersymmetric quantum chiral higher spin gravity

Abstract

We study quantum properties of supersymmetric mathcal{N} = 1 and mathcal{N} = 4 extensions of the four dimensional bosonic Chiral Higher Spin Gravities (HiSGRAs). We discuss the spectra, the classical actions and define the Feynman rules in mathcal{N} = 1 and mathcal{N} = 4 superspaces in the light-front gauge. Using these Feynman rules, we compute tree and one-loop amplitudes for these systems. A dimensional reduction to a system with mathcal{N} = 2 supersymmetry and with massive higher spin fields is performed and quantum properties of this system are discussed.
