Interactions in Higher-Spin Gravity: a Holographic Perspective — •Charlotte Sleight — Université Libre de Bruxelles, Brussels, Belgium

A long standing problem in theoretical physics is understanding if gauge fields of spin s > 2 can interact in a consistent manner. In this talk we review how the AdS/CFT correspondence (holography) seems to naturally imply the existence of consistent interacting theories of higher-spin gauge fields, which are believed to capture the high-energy regime of string theory. We also briefly discuss recent results which employ AdS/CFT to construct a possible non-linear action for higher-spin theories on an AdS background, free from auxiliary fields.
