Duality invariance in massive theories

TL;DR

This paper demonstrates how duality symmetry can be incorporated into massive theories through gauge-invariant actions, including a new approach for massive gravitons.

Contribution

It introduces a novel gauge-invariant action for massive gravitons and shows duality invariance in massive theories at the action level.

Findings

Duality symmetry can be implemented in massive theories with appropriate gauge-invariant actions.

A new gauge-invariant formulation for massive gravitons is proposed.

Duality invariance is achieved for both vector and graviton fields.

Abstract

In this work, we show that duality symmetry can be implemented for massive theories at the level of the action, whenever we can formulate appropriates gauge invariant actions. For a massive vectorial field, we use a known gauge invariant description, while for a massive graviton, we introduce a novel gauge invariant action in order to show duality invariance.
