Gauge Invariance with Mass: Higher Spins in Cosmological Spaces
نویسنده
چکیده
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 must tend to zero. Invited lecture, Francqui Conference, “Strings and Gravity: Tying the Forces Together”, Brussels, October 2001.

New Properties of Matter in (A)dS and their Consequences
I review briefly, primarily for relativists, a series of recent results, obtained with A. Waldron, on the novel behavior of massive higher (s > 1) spin systems in constant curvature backgrounds. We find that the cosmological constant Λ, together with the mass parameter, define a “phase plane” in which partially massless gauge invariant lines separate allowed regions from forbidden, non-unitary,...
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 کاملPhotons and Gravitons as Goldstone Bosons , and the Cosmological Constant
We reexamine a scenario in which photons and gravitons arise as Goldstone bosons associated with the spontaneous breaking of Lorentz invariance. We study the emergence of Lorentz invariant low energy physics in an effective field theory framework, with non-Lorentz invariant effects arising from radiative corrections and higher order interactions. Spontaneous breaking of the Lorentz group also l...
متن کامل(Dis)continuities of Massless Limits in Spin 3/2–mediated Interactions and Cosmological Supergravity
We extend to its spin 3/2 supersymmetric partner the very recent demonstration that the massless limit of massive spin 2 exchange amplitudes can be made continuous in background AdS spaces, in contrast to the known flat space discontinuities for both systems. In an AdS background, unlike spin 2 where the limit m → 0 is the massless one, spin 3/2 “masslessness” requires m → √ −Λ/3 , the supergra...
