Pasti-Sorokin-Tonin Actions in the Presence of Sources

TL;DR

This paper extends the Pasti-Sorokin-Tonin actions for self-dual and Maxwell fields to include sources, maintaining manifest Lorentz invariance and duality, using a method adapted from previous formalisms.

Contribution

It generalizes existing Lorentz-invariant actions to incorporate sources, enhancing their applicability in physical theories involving self-dual fields and duality.

Findings

Successfully incorporates sources into Pasti-Sorokin-Tonin actions.

Maintains manifest Lorentz invariance and electromagnetic duality.

Provides a framework for future applications with sources.

Abstract

Pasti, Sorokin and Tonin have recently constructed manifestly Lorentz-invariant actions for self-dual field strengths and for Maxwell fields with manifest electromagnetic duality. Using the method of Deser, Gomberoff, Henneaux and Teitelboim, we generalize these actions in the presence of sources.
