Massless infinite spin (super)particles and fields

Abstract

A new twistorial field formulation of a massless infinite spin particle is derived. We find a twistorial infinite spin field and derive its helicity decomposition. The twistorial equations of motion for infinite spin fields in the cases of integer and half-integer helicities are derived. We show that the infinite integer-spin field and infinite half-integer-spin field form the $\mathcal{N}=1$ infinite spin supermultiplet. The corresponding supersymmetry transformations are presented. We prove that the supersymmetry algebra is closed on-shell.
