E_{11} and Higher Spin Theories
arXiv:hep-th/0701026 · doi:10.1016/j.physletb.2007.03.061
Abstract
We consider the previous proposal of the author to use an extension of spacetime obtained by taking the non-linear realisation of the semi-direct product of E_{11} with a set of generators belonging to one of the fundamental representations of E_{11}. We determine, at low levels, the symmetries that the associated point particle moving in this generalised spacetime should possess and write down the corresponding action. Quantisation of similar actions has been shown to lead to the unfolded formulation of higher spin theories and we argue that the generalised coordinates will lead in the non-linear realisation to an infinite number of propagating higher spin fields.
