Matter coupling in partially constrained vielbein formulation of massive gravity
We consider a linear effective vielbein matter coupling without introducing the Boulware-Deser ghost in ghost-free massive gravity. This is achieved in the partially constrained vielbein formulation. We first introduce the formalism and prove the absence of ghost at all scales. As next we investigate the cosmological application of this coupling in this new formulation. We show that even if the...
متن کاملFrom Massive Gravity to Dark Matter Desity
Massive gravity previously constructed as the spin-2 quantum gauge theory is studied in the classical limit. The vector graviton field v which does not decouple in the limit of vanishing graviton mass gives rise to a modification of general relativity. The modified Schwarzschild solution contains a contribution from the v-field which can be interpreted as the dark matter mass density. ∗e-mail: ...

متن کاملAnti-gravity and/or dark matter contributions from massive gravity
Recently, the static spherically symmetric solution of the gravitational field equations have been found in theories describing massive graviton with spontaneous breaking of the Lorentz invariance [1]. These solutions, which show off two integration constants instead of one in General Relativity, are discussed. They are candidates for modified black holes provided they are stable against small ...
