• We study the BPS spectrum of four-dimensional N=2 SU(2) theory with massive fundamental matter fields using the D3-brane probe. Since the BPS states are realized by string webs subject to the BPS conditions, we determine explicitly the configurations of such webs. It is observed that there appear BPS string webs with multiple junctions corresponding to the fact that the curves of marginal stability in the massive theory are infinitely nested. In terms of the string configurations, various properties of the curves of marginal stability are described intuitively.
