Cosmic Acceleration and the Helicity-0 Graviton
Claudia de Rham, Gregory Gabadadze, Lavinia Heisenberg +1
We explore cosmology in the decoupling limit of a non-linear covariant extension of Fierz-Pauli massive gravity obtained recently in arXiv:1007.0443. In this limit the theory is a…
Resummation of Massive Gravity
Claudia de Rham, Gregory Gabadadze, Andrew J. Tolley
We construct four-dimensional covariant non-linear theories of massive gravity which are ghost-free in the decoupling limit to all orders. These theories resum explicitly all the n…
Generalization of the Fierz-Pauli Action
Claudia de Rham, Gregory Gabadadze
We consider the Lagrangian of gravity covariantly amended by the mass and polynomial interaction terms with arbitrary coefficients, and reinvestigate the consistency of such a theo…
Selftuned Massive Spin-2
Claudia de Rham, Gregory Gabadadze
We calculate the cubic order terms in a covariant theory that gives a nonlinear completion of the Fierz-Pauli massive spin-2 action. The resulting terms have specially tuned coeffi…
Field Theory for a Deuteron Quantum Liquid
Lasha Berezhiani, Gregory Gabadadze, David Pirtskhalava
Based on general symmetry principles we study an effective Lagrangian for a neutral system of condensed spin-1 deuteron nuclei and electrons, at greater-than-atomic but less-than-n…
