Titre  Higher spin physics 
Résumé  I will review two aspects in which higher spin fields play an important role. Firstly, higher spin states seem to be inevitable in models of quantum gravity, e.g. within AdS/CFT correspondence and in string theory. One of the simplest examples relates theories with massless higherspin fields, known as higher spin gravities, to (ChernSimons) vector models that describe many second order phase transitions in the real world and were conjectured to exhibit a number of dualities, including the 3d bosonization duality. I will review the progress towards constructing exact models of AdS/CFT along these lines and how higher spin symmetry is manifested on the CFT side and can be used to prove the 3d bosonization duality. Secondly, any massive and rotating compact object, e.g. a black hole, can be modelled by a higher spin particle. I will review the recent progress in constructing theories with massive higher spin fields with applications to the description of gravitational wave radiation from compact binaries.
