Localized Gravity in String Theory

TL;DR

This paper presents a string theory model that localizes gravity on an AdS4 brane within an AdS5 background using D-branes, providing a concrete realization of gravity localization.

Contribution

It introduces a string theory setup with M D5 branes in the near horizon geometry of N D3 branes to realize localized gravity on an AdS4 brane.

Findings

Successful construction of a string model localizing gravity.

Demonstration of gravity localization in the AdS4/AdS5 setup.

Potential implications for holography and brane-world scenarios.

Abstract

We propose a string realization of the AdS4 brane in AdS5 that is known to localize gravity. Our theory is M D5 branes in the near horizon geometry of N D3 branes, where M and N are appropriately tuned.
