Twistor formulation of massless 6D infinite spin fields

We construct massless infinite spin irreducible representations of the six-dimensional Poincare group in the space of fields depending on twistor variables. It is shown that the massless infinite spin representation is realized on the two-twistor fields. We present a full set of equations of motion for two-twistor fields represented by the totally symmetric SU(2) rank 2s two-twistor spin-tensor and show that they carry massless infinite spin representations. A field twistor transform is constructed and infinite spin fields are found in the space-time formulation with an additional spinor coordinate. (C) 2021 The Authors. Published by Elsevier B.V.
