Localizing Gravity on a 3-brane in Higher Dimensions
Tony Gherghetta
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 fro…
Living Inside a Hedgehog: Higher-dimensional Solutions that Localize Gravity
Tony Gherghetta, Ewald Roessl, Mikhail Shaposhnikov
We consider spherically symmetric higher-dimensional solutions of Einstein's equations with a bulk cosmological constant and n transverse dimensions. In contrast to the case of one…
New Directions for New Dimensions: From Strings to Neutrinos to Axions to...
Keith R. Dienes
In this talk, I discuss recent developments concerning the possibility of large extra spacetime dimensions. After briefly reviewing how such dimensions can lower the fundamental GU…
Localizing Gravity on a String-Like Defect in Six Dimensions
Tony Gherghetta, Mikhail Shaposhnikov
We present a metric solution in six dimensions where gravity is localized on a four-dimensional singular string-like defect. The corrections to four-dimensional gravity from the bu…
Bulk Fields and Supersymmetry in a Slice of AdS
Tony Gherghetta, Alex Pomarol
Five-dimensional models where the bulk is a slice of AdS have the virtue of solving the hierarchy problem. The electroweak scale is generated by a ``warp'' factor of the induced me…
