Massless Higher Spins and Holography
We treat free large N superconformal field theories as holographic duals of higher spin (HS) gauge theories expanded around AdS spacetime with radius R. The HS gauge theories contain massless and light massive AdS fields. The HS current correlators are written in a crossing symmetric form including only exchange of other HS currents. This and other arguments point to the existence of a consiste...
متن کاملGauge Invariance with Mass: Higher Spins in Cosmological Spaces
I review recent work on massive higher (s > 1) spins in constant curvature (deSitter) spaces. Some of the novel properties that emerge are: partial masslessness and new local gauge invariances, unitarily forbidden ranges of mass, correlation between fermions/bosons and nagative/positive cosmological constant Λ and finally the consistency requirement that in the limit of infinite spin towers, Λ ...
متن کاملConformal Invariance of Partially Massless Higher Spins
We show that there exist conformally invariant theories for all spins in d = 4 de Sitter space, namely the partially massless models with higher derivative gauge invariance under a scalar gauge parameter. This extends the catalog from the two known gauge models – Maxwell and partially massless spin 2 – to all spins.
متن کاملInconsistencies of Massive Charged Gravitating Higher Spins
We examine the causality and degrees of freedom (DoF) problems encountered by charged, gravitating, massive higher spin fields. For spin s=3/2, making the metric dynamical yields improved causality bounds. These involve only the mass, the product eMP of the charge and Planck mass and the cosmological constant Λ. The bounds are themselves related to a gauge invariance of the timelike component o...
متن کاملNonlinear Realizations in Tensorial Superspaces and Higher Spins
In the first part of the talk I report on surprising relations between higher spin (HS) theory and nonlinear realizations of the supergroup OSp(1|8), a minimal superconformal extension of N = 1, 4D supersymmetry with tensorial charges. The second part is a review of the “master” model of HS particle which makes manifest the classical equivalence of two previously known HS particle formulations ...
