On the Non-Abelian Born-Infeld Action

Abstract

We discuss some asp ects of the generalization of the Born-Infeld action to non-abelian gauge groups and show how the discrepancy between Tseytlin’s symmet rized trace proposal and string theory can be corrected at order F ⁶. We also comment on the possible quadratic order fermionic terms. UMR 8549 du Centre National de la Recherche Scientifique et de l’École Normale Supérieure.
