# Walls of marginal stability and dyon spectrum in N = 4 supersymmetric string theories

@article{Sen2007WallsOM, title={Walls of marginal stability and dyon spectrum in N = 4 supersymmetric string theories}, author={Ashoke Sen}, journal={Journal of High Energy Physics}, year={2007}, volume={2007}, pages={039-039} }

The spectrum of quarter BPS dyons in N = 4 supersymmetric string theories can change as the asymptotic moduli cross walls of marginal stability on which the dyon can break apart into a pair of half BPS states. In this paper we classify these marginal stability walls and examine this phenomenon in the context of exact dyon spectrum found in a class of N = 4 supersymmetric string theories. We argue that the dyon partition functions in different domains separated by marginal stability walls are…
