Wall and Anti-Wall in the Randall-Sundrum Model and A New Infrared Regularization
نویسنده
چکیده
Abstract An approach to find the field equation solution of the Randall-Sundrum model with the S/Z2 extra axis is presented. We closely examine the infrared singularity. The vacuum is set by the 5 dimensional Higgs field. Both the domain-wall and the anti-domain-wall naturally appear, at the ends of the extra compact axis, by taking a new infrared regularization. The stability is guaranteed from the outset by the kink boundary condition. A continuous (infrared-)regularized solution, which is a truncated Fourier series of a discontinuous solution, is utilized.The ultraviolet-infrared relation appears in the leading order of the solution.

A Solution of the Randall-Sundrum Model and the Mass Hierarchy Problem
Abstract A solution of the Randall-Sundrum model for a simplified case (one wall) is obtained. It is given by the 1/k-expansion (thin wall expansion) where 1/k is the thickness of the domain wall. The vacuum setting is done by the 5D Higgs potential and the solution is for a family of the Higgs parameters. The mass hierarchy problem is examined. Some physical quantities in 4D world such as the ...

متن کاملFrom soft walls to infrared branes
Five-dimensional warped spaces with soft walls are generalizations of the standard Randall-Sundrum compactifications, where instead of an infrared brane one has a curvature singularity (with vanishing warp factor) at finite proper distance in the bulk. We project the physics near the singularity onto a hypersurface located a small distance away from it in the bulk. This results in a completely ...
متن کاملSolitons in Brane Worlds
We study some aspects of dilatonic domain walls in relation to the idea on the noncompact internal space. We find that the warp factor in the spacetime metric increases as one moves away from the domain wall for all the supersymmetric dilatonic domain wall solutions obtained from the (intersecting) BPS branes in string theories through toroidal compactifications, unlike the case of the Randall-...
متن کاملEntropy of the Randall-Sundrum black brane in the brick-wall method
We calculate the entropy of the black brane of the Randall-Sundrum(RS) model by using the brick-wall method. The modes along the extra dimension are semi-classically quantized on the orbifold. The number of modes in the extra dimension is remarkably given as a simple form with the help of the RS mass relation, and then the entropy for the scalar modes in the fivedimensional spacetime is describ...
