研究了四维时空中${\cal N}=1$ SUSY非线性σ模型，得到了BPS壁和结.本文发现了一个具有单手征标量超场的非线性σ模型，它的模空间拓扑为S^1 $，模空间中任意点都有BPS壁和结点。新的BPS结解决方案连接$N$离散真空也发现了几个手征标量超场的非线性西格玛模型。有关我们的结果的更详细的说明可以在参考文献[1]中找到。引用{NNS}。
The ${\cal N}=1$ 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 superfield is found which has a moduli space of the topology of $S^1$ and admits BPS walls and junctions connecting arbitrary points in moduli space. New BPS junction solutions connecting $N$ discrete vacua are also found for nonlinear sigma models with several chiral scalar superfields. More detailed exposition of our results can be found in Ref.\cite{NNS}.
