We investigate domain wall junctions in a generalized Wess-Zumino model with a Z(N) symmetry. We present a method to identify the junctions which are potentially BPS saturated. We then use a numerical simulation to show that those junctions indeed saturate the BPS bound for N=4. In addition, we study the decay of unstable non-BPS junctions.doi:10.1016/s0370-2693(00)00087-3 fatcat:rq7fbh6kbndxzc5xrjqrpixyx4
