Three String Junction and N=4 Dyon Spectrum

Understand

The exact spectrum of dyons in a class of N=4 supersymmetric string theories gives us information about dyon spectrum in N=4 supersymmetric gauge theories.

• This in turn can be translated into prediction about the BPS spectrum of three string junctions on a configuration of three parallel D3-branes.
• We show that this prediction agrees with the known spectrum of three string junction in different domains in the moduli space separated by walls of marginal stability.
