Abstract
We examine the interrelation between the (2,0) supersymmetric six dimensional effective action for the A_1 theory, and the corresponding low-energy theory for the collective coordinates associated to supersymmetric selfdual BPS strings. We argue that this low-energy theory is a two-dimensional N = 4 supersymmetric sigma model.
