Cosmology of Randall-sundrum Models∗
For past two years, many particle physicists and cosmologists were excited by the development of two ideas, the brane world and the warped extra dimensions, both of which are based on the existence of extra dimensions. The basic idea of the brane world is that standard model particles are localized on a (3+1)-dimensional brane (or a set of branes) embedded in a higher dimensional spacetime, whi...
متن کاملGravity in the randall-sundrum brane world
We discuss the weak gravitational field created by isolated matter sources in the Randall-Sundrum brane world. For the case of a single wall of positive tension, the field stays localized near the wall if the source is stationary. We calculate the leading Kaluza-Klein corrections to the linearized gravitational field of a nonrelativistic spherical object, which is different from the Schwarzschi...
متن کاملGravity in Randall-Sundrum Brane World Revisited
We point out some subtleties with gauge fixings (which sometimes include the so-called “brane bending” effects) typically used to compute the graviton propagator on the Randall-Sundrum brane. In particular, the brane, which has non-vanishing tension, explicitly breaks some part of the diffeomorphisms, so that there are subtleties arising in going to, say, the axial gauge or the harmonic gauge. ...
متن کاملTunneling into the Randall-Sundrum Brane World
We suggest a modification of the Randall-Sundrum scenario which doesn’t involve branes with the negative tensions. In our scenario four-dimensional brane world is produced by the external field. The probability of this process is calculated and the physical features of the model are discussed. 1. The alternative to compactification suggested recently in [1] attracts a lot of attention nowadays....
متن کاملRandall - Sundrum Gauge in the Brane World
We discuss the Randall-Sundrum (RS) gauge in the brane-world. We begin with the de Donder gauge (transverse-tracefree) in five dimensions for comparison. One finds that h55 = 0 and h5μ has a tachyonic mass. Hence we have to set h5μ = 0. This leads to the RS gauge. It appears that the RS gauge is so restrictive for the five massless states, whereas it is unique for describing the massive states....
