# Photon mass via current confinement

## TL;DR

This paper demonstrates that photon mass can arise from current confinement in a three-dimensional parity invariant Dirac theory, without spontaneous symmetry breaking, highlighting a novel mechanism for photon mass generation.

## Contribution

It introduces a new mechanism where current confinement in a three-dimensional Dirac theory imparts mass to the photon, independent of symmetry breaking.

## Key findings

- Photon becomes massive due to current confinement.
- Mass generation is independent of spontaneous symmetry breaking.
- The theory is parity invariant with two massive Dirac fields.

## Abstract

A parity invariant theory, consisting of two massive Dirac fields, defined in three dimensional space-time, with the confinement of a certain current is studied. It is found that the electromagnetic field, when coupled minimally to these Dirac fields, becomes massive owing to the current confinement. It is seen that the origin of photon mass is not due to any kind of spontaneous symmetry breaking, but only due to current confinement.
