## Idea

The target space spectrum of the string sigma-model contains beyond the massless particles of the effective supergravity theory an infinite tower of massive excitations, of ever higher spin. There are, however, certain limits in which all these masses become negligible to a reference energy scale, notably for compactifications on anti de Sitter spaces of small radius. In this limit the string spectrum looks like a an infinite collection of massless spinning particles for ever higher spin. Due to their common orgin in the string, these share intricate relations among each other, which are described by what Vasiliev termed higher spin gauge theory.
