BPS Walls and Junctions in $\mathcal{N}=1$ SUSY Nonlinear Sigma Models

Masashi Naganuma, Muneto Nitta, Norisuke Sakai

The $\mathcal{N}=1$ SUSY nonlinear sigma models in four spacetime dimensions are studied to obtain BPS walls and junctions. A nonlinear sigma model with a single chiral scalar superfi…
