No Ghost State in the Brane World
We discuss the role of the trace part of metric fluctuations h M N in the Randall-Sundrum scenario of gravity. Without the matter, this field (h = η M N h M N) is a gauge-dependent term, and thus it can be gauged away. But, including the matter source T M N , this field satisfies the linearized equation 2 4 h = 16πG 5 T µ µ. This may correspond to the scalar ξ 5 in the bending of the brane due ...
متن کاملGhost Condensation in the Brane-World
Motivated by the ghost condensate model, we study the Randall-Sundrum (RS) brane-world with an arbitrary function of the higher derivative kinetic terms, P(X), where X = −(∂φ)2. The five-dimensional Einstein equations reduce to two equations of motion with a constraint between P(X) and the five-dimensional cosmological constant on the brane. For a static extra dimension, P(X) has solutions of t...
متن کاملStandard Cosmology in the DGP Brane Model
In recent years large extra dimensions which can only be probed by gravitons and eventually non-standard matter have attracted a lot of attention. These models usually yield the correct Newtonian (1/r)-potential at large distances because the gravitational field is quenched on submillimeter transverse scales. This quenching appears either due to finite extension of the transverse dimensions [1]...
متن کاملNewton Law in DGP Brane-World with Semi-Infinite Extra Dimension
Newton potential for DGP brane-world scenario is examined when the extra dimension is semi-infinite. The final form of the potential involves a self-adjoint extension parameter α, which plays a role of an additional mass (or distance) scale. The striking feature of Newton potential in this setup is that the potential behaves as seven-dimensional in long range when α is nonzero. For small α ther...
