Abstract

For a brane world embedded in various ten or eleven-dimensional geometries, we calculate the corrections to the four-dimensional gravitational potential due to graviton modes propagating in the extra dimensions, including those rotating around compact directions. Due to additional "warp" factors, these rotation modes may have as significant an effect as the s-wave modes which propagate in the large or infinite extra dimension.
