Newton Law on the Generalized Singular Brane with and without 4d Induced Gravity
نویسندگان
چکیده
Newton law arising due to the gravity localized on the general singular brane embedded in AdS5 bulk is examined in the absence or presence of the 4d induced Einstein term. For the RS brane, apart from the subleading correction, Newton potential obeys 4d-type and 5d-type gravitational law at longand short-ranges if it were not for the induced Einstein term. The 4d induced Einstein term generates an intermediate range at short distance, in which the 5d Newton potential 1/r2 emerges. For Neumann brane the long-range behavior of Newton potential is exponentially suppressed regardless of the existence of the induced Einstein term. For Dirichlet brane the expression of Newton potential is dependent on the renormalized coupling constant v. At particular value of v Newton potential on Dirichlet brane exhibits a similar behavior to that on RS brane. For other values the long-range behavior of Newton potential is exponentially suppressed as that in Neumann brane. ∗Email:[email protected] †Email:[email protected] ‡Email:[email protected] 1

Newton Law in Brane-World Scenario with 4d Induced Gravity: Singular Quantum Mechanical Approach
From the viewpoint of the singular quantum mechanics the effect of the energy-dependent coupling constant for δ-function potential is examined. The energy-dependence of the coupling constant naturally generates the timederivative in the boundary condition of the Euclidean propagator. This is explicitly confirmed by making use of the simple 1d model. The result is applied to the linearized gravi...
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...

In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
متن کاملCorrection terms to Newton law due to induced gravity in AdS background
We calculate small correction terms to gravitational potential on RandallSundrum brane with an induced Einstein term. The behaviors of the correction terms depend on the magnitudes of AdS radius k−1 and a characteristic length scale λ of model. We present the gravitational potential for arbitrary k and λ at all distances. ∗E-mail address: [email protected] 1 Braneworld is based on t...
متن کاملStrong Coupling Holography
We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4 + d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong coupling scale of the 4D theory. This connection persists in the limit in which gravity can be consistently decoupled. We demonstrate this e...
