String theory provides landmarks fixing RS branes' positions: Possibility to deduce large mass hierarchy from small numbers

TL;DR

This paper generalizes the RS-I two-brane model within higher-dimensional string-inspired theories, demonstrating how brane positions and mass hierarchies depend on the dimensionalities of extra subspaces.

Contribution

It introduces a higher-dimensional string-inspired framework for the RS model, linking brane positions and mass hierarchy to the dimensions of additional subspaces.

Findings

Mass hierarchy depends on the dimensionalities of extra subspaces.

Brane positions can be fixed using string theory landmarks.

The model extends RS scenarios to higher dimensions with dilaton and form fields.

Abstract

Two-branes RS-I 5-dimensional model is generalized in higher dimensional string-induced theory with dilaton and $n$-form field. It is supposed that "hidden" and "visible" Randall-Sundrum branes are located at the boundaries of region of space-time where low-energy supergravity description is valid. This permits to determine mass scale hierarchy which calculated value proves to be strongly dependent on dimensionalities of subspaces.
