E. A. Bergshoeff, M. de Roo, A. Sevrin

TL;DR
This paper reviews an iterative method to construct the supersymmetric non-abelian Born-Infeld action up to second order in field strength, revealing deviations from the symmetrized trace proposal due to kappa-invariance.
Contribution
It introduces a new iterative approach to derive the supersymmetric non-abelian Born-Infeld action, highlighting deviations from existing symmetrized trace models.
Findings
Kappa-invariance determines the ordering of terms.
Deviations from the symmetrized trace proposal are identified.
Action constructed up to second order in field strength.
Abstract
We review an iterative construction of the supersymmetric non-abelian Born-Infeld action. We obtain the action through second order in the fieldstrength. Kappa-invariance fixes the ordenings which turn out to deviate from the symmetrized trace proposal.
