Abstract

A Higher Spin Gravity in five dimensions is constructed. It was shown recently that constructing formally consistent classical equations of motion of higher spin gravities is equivalent to finding a certain deformation of a given higher spin algebra. A strong homotopy algebra encoding the interaction vertices then follows. We propose two different and novel realizations of the deformed higher spin algebra in the case of five dimensions: one in terms of the universal enveloping algebra of su(2, 2) and the other by means of oscillator variables. Both the new realizations admit supersymmetric extensions and the N = 8 case underlies the massless sector of tensionless strings. (C) 2019 The Author(s). Published by Elsevier B.V.
