Vacuum Expectation Value Profiles of the Bulk Scalar Field in the Generalized Randall-Sundrum Model
In the generalized Randall-Sundrum warped brane-world model the cosmological constant induced on the visible brane can be positive or negative. In this paper we investigate profiles of vacuum expectation value of the bulk scalar field under general Dirichlet and Neumann boundary conditions in the ge...

| description | In the generalized Randall-Sundrum warped brane-world model the
cosmological constant induced on the visible brane can be positive
or negative. In this paper we investigate profiles of vacuum
expectation value of the bulk scalar field under general Dirichlet
and Neumann boundary conditions in the generalized warped brane-world model. We show that the VEV profiles generally depend on the value
of the brane cosmological constant. We find that the VEV profiles of
the bulk scalar field for a visible brane with negative cosmological
constant and positive tension are quite distinct from those of
Randall-Sundrum model. In addition we show that the VEV profiles for
a visible brane with large positive cosmological constant are also
different from those of the Randall-Sundrum
model. We also verify that Goldberger and Wise mechanism can work under nonzero Dirichlet
boundary conditions in the generalized Randall-Sundrum model. |
