%0 Journal Article %T Complex BPS domain walls and phase transition in mass in supersymmetric QCD %A A. Smilga %A A. Veselov %J Physics %D 1997 %I arXiv %R 10.1103/PhysRevLett.79.4529 %X We study the domain walls connecting different chirally asymmetric vacua in supersymmetric QCD. We show that BPS - saturated solutions exist only in the limited range of mass. When m exceeds some critical value, the domain wall either ceases to be BPS - saturated or disappears altogether. In any case, the properties of the system are qualitatively changed. %U http://arxiv.org/abs/hep-th/9706217v2
