Pasti-Sorokin-Tonin Actions in the Presence of 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.Comment: 6 pages, LaTe
