Recently, Randall and Sundrum proposed a solution to the hierarchy problem where the background spacetime is five dimensional. There are two 3-branes, and the mass scale for fields that propagate on one of the 3-branes is exponentially suppressed relative to the fundamental scale of the theory, which is taken to be the Planck mass MPl. In this Brief Report we show that bulk fields with a five dimensional mass term of order MPl have, after integrating over the extra dimension, modes with four…

Bulk Higgs field in a Randall-Sundrum model with a nonvanishing brane cosmological constant
We consider the possibility of the Higgs mechanism in the bulk in a generalized Randall-Sundrum model, where a nonvanishing cosmological constant is induced on the visible brane. This scenario has
Cosmology of Randall–Sundrum models with an extra dimension stabilized by balancing bulk matter
Abstract We provide the cosmological solutions for Randall–Sundrum models with the bulk energy-momentum T 5 5 incorporated. It alters the Friedmann equation for the brane scale factor. We make a
Stability analysis of the Randall-Sundrum braneworld in presence of bulk scalar
Abstract The stability problem of Randall–Sundrum braneworld is readdressed in the light of stabilizing bulk scalar fields. It is shown that in such scenario the instability in general persists
Mass hierarchy from recoiling D-branes
Using conformal field theory methods we construct a metric that describes the distortion of space-time surrounding a D(irichlet)-brane (solitonic) defect after being struck by another D-brane. By
Braneworlds, conformal fields and the gravitons
We investigate the dynamics of Randall–Sundrum AdS5 braneworlds with five-dimensional conformal matter fields. In the scenario with a compact fifth dimension the class of conformal fields with weight
Quantised bulk fields in the Randall-Sundrum compactification model ∗
Abstract The quantisation of a scalar field in the five-dimensional model suggested by Randall and Sundrum is considered. Using the Kaluza–Klein reduction of the scalar field, discussed by Goldberger
Matter-gravity interaction in a multiply warped braneworld,
The role of a bulk graviton in predicting the signature of extra dimensions through collider-based experiments is explored in the context of a multiply warped spacetime. In particular it is shown
Braneworlds and dark energy
In the Randall–Sundrum scenario, we analyse the dynamics of an AdS5 braneworld when conformal matter fields propagate in five dimensions. We show that conformal fields of weight −4 are associated
We construct an inflation model on the Randall–Sundrum I (RSI) brane where a bulk scalar field stabilizes the inter-brane separation. We study impact of the bulk scalar field on the inflationary
Moduli fields and brane tensions: Generalizing the junction conditions
Taking the Randall-Sundrum models as a background scenario, we derive generalized Israel-Lanczos-Sen thin-shell junction conditions for systems in which several bulk scalar fields are nonminimally


Inflation in the five-dimensional universe with an orbifold extra dimension
Abstract New inflationary solutions to the Einstein equation are explicitly constructed in a simple five-dimensional model with an orbifold extra dimension S 1 / Z 2 . We consider inflation caused by
Exponential and Power-Law Hierarchies from Supergravity
Abstract We examine how a d-dimensional mass hierarchy can be generated from a d+1-dimensional set up. We introduce a d+1-dimensional scalar, the hierarchon, which has a potential as in gauged
A Large mass hierarchy from a small extra dimension
We propose a new higher-dimensional mechanism for solving the hierarchy problem. The weak scale is generated from the Planck scale through an exponential hierarchy. However, this exponential arises
SN1987A Constraints on Large Compact Dimensions
Recently there has been a lot of interest in models in which gravity becomes strong at the TeV scale. The observed weakness of gravitational interactions is then explained by the existence of extra
An Alternative to compactification
Conventional wisdom states that Newton's force law implies only four noncompact dimensions. We demonstrate that this is not necessarily true in the presence of a nonfactorizable background geometry.
Cosmology of One Extra Dimension with Localized Gravity
We examine the cosmology of the two recently proposed scenarios for a five dimensional universe with localized gravity. We find that the scenario with a non-compact fifth dimension is potentially
