Description
The formulation of consistent theories involving particles with arbitrary spin represents an old open theoretical challenge. In the massless case the corresponding gauge theories provide far-reaching generalisations of Yang-Mills theory and General Relativity, while massive higher-spin states are known to represent essential ingredients of the spectrum of String Theory. I will describe the basics of higher-spin constructions in flat and (Anti-) de Sitter backgrounds and review some recent progress on the subject, aiming to better frame the question of how to provide a bridge between the massless regime and its possible broken phases.
