Gravitational Localization of Matters in 6D

TL;DR

This paper introduces a new six-dimensional brane model with a negative cosmological constant, demonstrating that gravity alone can localize all types of matter fields on the brane.

Contribution

It provides a novel 3-brane solution in 6D spacetime with a stringlike defect, showing gravitational localization of matter fields without additional interactions.

Findings

All local fields are localized on the brane via gravity.

The solution features a decreasing scale function approaching a finite value.

The model extends brane-world scenarios to six dimensions with a negative cosmological constant.

Abstract

We present a new 3-brane solution to Einstein's equations in (1+5)-spacetime with a negative bulk cosmological constant. This solution is a stringlike defect solution with decreasing scale function approaching a finite non-zero value in the radial infinity. It is shown that all local fields are localized on the brane only through the gravitational interaction.
