Contribution
It introduces a method to identify BPS-saturated junctions and confirms their saturation via numerical simulation for N=4, also studying decay of unstable junctions.
Findings
BPS saturation confirmed for N=4 junctions
Method to identify BPS junctions in the model
Decay behavior of non-BPS junctions analyzed
Abstract
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.
