Conformal 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 کاملMassless 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 کاملNull Propagation of Partially Massless Higher Spins in (A)dS and Cosmological Constant Speculations
We show explicitly that all partially and strictly massless higher spins s ≤ 3 propagate on the (A)dS null cone. Assuming that this property holds also for s > 3 we derive the mass-cosmological constant tunings for all higher spin partially massless theories. As s increases, the unitarily allowed region for massive spins in cosmological backgrounds is squeezed around Λ = 0 so that an infinite t...
متن کاملPM1⁄4EM? Partially massless duality invariance
is almost coeval with Maxwell’s equations themselves, although a proof of its validity awaited over a century [1,2]. In addition to countless generalizations of ‘‘duality’’ in field and string theory, it has led to an enormous variety of more precise analogs, in particular to spin 2 [2,3], then to all free massless (integer or half-integer) spin s > 0 systems in flat space [4,5]. In de Sitter (...
متن کاملNonlinear partially massless from massive gravity?
We show that consistent nonlinear partially massless models cannot be obtained starting from ‘‘f-g’’ massive gravity, with ‘‘f’’ the embedding de Sitter space. The obstruction, which is also the source of f-g acausality, is the very same fifth constraint that removes the notorious sixth ghost excitation. Here, however, it blocks extension of the gauge invariance (appearing for mass to de Sitter...
