How to build a compact brane

TL;DR

This paper introduces a new class of five-dimensional braneworld models with a scalar field that controls the brane's thickness, enabling the creation of a compact brane profile in infinite extra dimension scenarios.

Contribution

It presents a novel family of models where a scalar field parameter tunes the brane's thickness, leading to compact brane configurations in warped geometries.

Findings

A scalar field parameter controls brane thickness.

The models produce compact brane profiles.

The approach extends previous braneworld constructions.

Abstract

This work deals with braneworld models in a five dimensional curved geometry with a single extra dimension of infinite extent. The investigation introduces a new family of models, generated from a source scalar field that supports kinklike structures described through the presence of a real parameter, capable of controlling the thickness of the warp factor that describes the five dimensional geometry. The mechanism shows how to get a brane that engenders a compact profile.
