TL;DR

This paper proposes a mechanism using a five-dimensional Stueckelberg-like action to localize abelian gauge fields and Kalb--Ramond fields on thick branes, identifying conditions for normalizable zero modes.

Contribution

It introduces a novel localization mechanism for abelian gauge and Kalb--Ramond fields on thick branes using a five-dimensional Stueckelberg-like action.

Findings

Normalizable zero modes for gauge fields are achieved.

The mechanism is applicable to both gauge and Kalb--Ramond fields.

A suitable coupling function is identified for localization.

Abstract

In this work, we explore a mechanism for abelian gauge field localization on thick branes based on a five-dimensional Stueckelberg-like action. A normalizable zero mode is found through the identification of a suitable coupling function between the brane and the gauge field. The same mechanism is studied for the localization of the abelian Kalb--Ramond field.
