Who's afraid of higher spin theories?
A seminar to celibrate the 20th anniversary of the Newton Institute.
Interacting theories of higher spin gauge fields are a very nontrivial generalisation of Einstein gravity. They seem to be consistently defined only in spacetimes with a non-zero cosmological constant where their strucutre is powerfully constrained by the large symmetry. In recent times, these theories (on anti de sitter space) have proved to be very interesting laboratories for non-supersymmetric versions of the AdS/CFT correspondence. I will give an overview of these topics and why they might be of interest even beyond the string theory context.
