在N=2超对称（SUSY） QED中，得到了三个大质量超多重态的畴壁结的精确解。接合处保留了八个超对称性中的两个。超多重态的结解需要（磁性）Fayet-Iliopoulos （FI）项和复质量。自发破动、SUSY和U(1)对应的模式为零。在N=1超场和分量中，所有破缺和未破缺的超对称性电荷都在Wess-Zumino规范中得到了明确的计算。阐明了与五个维度模型的关系。
An exact solution of domain wall junction is obtained in N=2 supersymmetric (SUSY) QED with three massive hypermultiplets. The junction preserves two out of eight SUSY. Both a (magnetic) Fayet-Iliopoulos (FI) term and complex masses for hypermultiplets are needed to obtain the junction solution. There are zero modes corresponding to spontaneously broken translation, SUSY, and U(1). All broken and unbroken SUSY charges are explicitly worked out in the Wess-Zumino gauge in N=1 superfields as well as in components. The relation to models in five dimensions is also clarified.
