Gravity localization with a domain wall junction in six dimensions

TL;DR

This paper investigates how gravity can be localized on a four-dimensional brane within a six-dimensional supergravity-inspired model, revealing that domain wall junctions can trap massless gravitons with tension cancellation effects.

Contribution

It demonstrates gravity localization via domain wall junctions in six dimensions with a supergravity-motivated scalar potential, highlighting tension cancellation mechanisms.

Findings

Massless graviton localized on the junction.

Tension cancels locally due to metric effects.

Distinct from global supersymmetric models.

Abstract

We study gravity localization in the context of a six-dimensional gravity model coupled with complex scalar fields. With a supergravity-motivated scalar potential, we show that the domain wall junction solutions localize a four-dimensional massless graviton under an assumption on the wall profile. We find that unlike the global supersymmetric model, contributions to the junction tension cancel locally with gravitational contributions. The wall tension vanishes due to the metric suppression.
