Abstract

We discuss recent results on one-loop contributions to the effective action in N=4 supersymmetric Yang-Mills theory in four dimensions. Contributions with five external vector fields are compared with corresponding ones in open superstring theory in order to understand the relation with the F5 terms that appear in the nonabelian generalization of the Born-Infeld action.
