Massive Gravity Acausality Redux
Massive gravity (mGR) is a 5(=2s+1) degree of freedom, finite range extension of GR. However, amongst other problems, it is plagued by superluminal propagation, first uncovered via a second order shock analysis. First order mGR shock structures have also been studied, but the existence of superluminal propagation in that context was left open. We present here a concordance of these methods, by ...
متن کاملMore on Massive 3D Gravity
We explore the space of static solutions of the recently discovered three-dimensional ‘New Massive Gravity’ (NMG), allowing for either sign of the Einstein-Hilbert term and a cosmological term parametrized by a dimensionless constant λ. For λ = −1 we find black hole solutions asymptotic (but not isometric) to the unique (anti) de Sitter vacuum, including extremal black holes that interpolate be...
متن کاملMassive Loop Amplitudes from Unitarity
We show, for previously uncalculated examples containing a uniform mass in the loop, that it is possible to obtain complete massive one-loop gauge theory amplitudes solely from unitarity and known ultraviolet or infrared mass singularities. In particular, we calculate four-gluon scattering via massive quark loops in QCD. The contribution of a heavy quark to five-gluon scattering with identical ...
متن کاملMassive Spin-5/2 Fields Coupled to Gravity: Tree-Level Unitarity vs. the Equivalence Principle
I show that the gravitational scattering amplitudes of a spin-5/2 field with mass m ≪ MP l violate tree-level unitarity at energies √ s ≈ √ mMP l if the coupling to gravity is minimal. Unitarity up to energies √ s ≈ MP l is restored by adding a suitable non-minimal term, which gives rise to interactions violating the (strong) equivalence principle. These interactions are only relevant at distan...
متن کاملFe b 20 16 Holographically Viable Extensions of Topologically Massive and Minimal Massive Gravity ?
Recently [1], an extension of the topologically massive gravity (TMG) in 2+1 dimensions, dubbed as minimal massive gravity (MMG), which is free of the bulk-boundary unitarity clash that inflicts the former theory and all the other known three dimensional theories, was found. Field equations of MMG differ from those of TMG at quadratic terms in the curvature that do not come from the variation o...
