Localizing gravity on a 3-brane in higher dimensions
INTERNATIONAL JOURNAL OF MODERN PHYSICS A | WORLD SCIENTIFIC PUBL CO PTE LTD | Published : 2001
We present metric solutions in six and higher dimensions with a bulk cosmological constant, where gravity is localized on a 3-brane. The corrections to four-dimensional gravity from the bulk continuum modes are power-law suppressed. Furthermore, the introduction of a bulk "hedgehog" magnetic field leads to a regular geometry, and can localize gravity on the 3-brane with either positive, zero or negative bulk cosmological constant.
