Warped and compact extra dimensions: 5D branes in 6D models

TL;DR

This paper explores six-dimensional brane world models with compact and warped extra dimensions, demonstrating how they can address the hierarchy problem using a single positive tension brane.

Contribution

It introduces a class of 6D models with a single 5D brane and a finite warped extra dimension, combining features of ADD and Randall-Sundrum models.

Findings

Hierarchy problem solvable on a single positive tension brane

Models exhibit features from both ADD and Randall-Sundrum scenarios

Finite warped extra dimension with a compact brane dimension

Abstract

We consider six dimensional brane world models with a compact and a warped extra dimension with five dimensional branes. We find that such scenarios have many interesting features arising from both ADD and Randall-Sundrum -models. In particular we study a class of models with a single 5D brane and a finite warped extra dimension, where one of the brane dimensions is compact. In these models the hierarchy problem can be solved on a single positive tension brane.
