Nonlinear 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...
متن کاملGeometric Formulation for Partially Massless Fields
The manifestly gauge invariant formulation for free symmetric higher-spin partially massless fields in (A)dSd is given in terms of gauge connections and linearized curvatures that take values in the irreducible representations of (o(d−1, 2)) o(d, 1) described by two-row Young tableaux, in which the lengths of the first and second row are, respectively, associated with the spin and depth of part...
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 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 کاملNon-linear duality invariant partially massless models?
Article history: Received 10 November 2015 Accepted 9 December 2015 Available online 15 December 2015 Editor: M. Cvetič We present manifestly duality invariant, non-linear, equations of motion for maximal depth, partially massless higher spins. These are based on a first order, Maxwell-like formulation of the known partially massless systems. Our models mimic Dirac–Born–Infeld theory but it is ...
