Towards a Supersymmetric Non-Abelian Born-Infeld Theory.

We define an iterative procedure to obtain a non-abelian generalization of the BornInfeld action. This construction is made possible by the use of the severe restrictions imposed by kappa-symmetry. We have calculated all bosonic terms in the action up to terms quartic in the Yang-Mills field strength and all fermion bilinear terms up to terms cubic in the field strength. Already at this order the fermionic terms do not satisfy the symmetric trace-prescription. [ABSTRACT FROM AUTHOR]
