A Note About Localized Photons on the Brane

TL;DR

This paper investigates the localization of photons in a five-dimensional model with a brane, concluding that massive photons cannot be confined to the brane using the Randall-Sundrum mechanism.

Contribution

It provides a first order formulation for Maxwell fields in five dimensions and analyzes photon localization, revealing limitations of the Randall-Sundrum mechanism.

Findings

Massive photons cannot be localized on the brane.

First order formulation aids in analyzing higher-dimensional gauge fields.

Abstract

A first order formulation for the Maxwell field in five dimensions is dimensionally reduced using the Randall-Sundrum mechanism. We will see that massive photons can not be localized on the brane.
