Supersymmetric quantum chiral higher spin gravity

Abstract

Abstract We study quantum properties of supersymmetric N $$ \mathcal{N} $$ = 1 and N $$ \mathcal{N} $$ = 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 N $$ \mathcal{N} $$ = 1 and N $$ \mathcal{N} $$ = 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 N $$ \mathcal{N} $$ = 2 supersymmetry and with massive higher spin fields is performed and quantum properties of this system are discussed.
