Title: Domain walls and their junctions from N=1 quarks and gluons
Abstract: In this talk we are going to discuss multiplicities and junctions of BPS domain walls interpolating between different chiral vacua in N=1 supersymmetric QCD (SQCD) with the SU(N) gauge group and a varying number of fundamental quarks. Depending on the number of flavors F two distinct classes of degenerate domain walls emerge: (i) locally distinguishable, i.e. those which differ from each other locally, in local experiments; and (ii) those which have identical local structure and are differentiated only topologically, through judicially chosen compactifications. In the first class two-wall junctions exist while in the second class such junctions do not exist. Acharya and Vafa counted topologically distinguishable walls in pure super-Yang-Mills. Ritz, Shifman and Vainshtein counted the locally distinguishable walls in F=N SQCD. In both cases the multiplicity of k walls was the same, N!/[(N−k)!k!]. We study the general case 0<=F<=N, with mixed sets of walls from both classes (i) and (ii) simultaneously, and demonstrate that the above overall multiplicity remains intact. We argue that the growth of the quark masses exhibits no phase transition at any finite masses. The locally distinguishable walls can turn into topologically distinguishable only at m=infinity. An evolution of the low-energy wall world sheet theory in passage from small to large m is briefly discussed. We also propose a candidate for the low-energy description of wall junctions.
