我们考虑了一类新的手征超场约束，得到了四维时空中的超对称非线性σ模型，它严格地将内部对称破缺和自发超对称破缺联合收割机结合起来.由此产生的无质量模可以是唯一的南武-戈德斯通玻色子，没有它们的复杂伙伴和在内部对称下带电的戈德斯通玻色子。大质量模的质量与对称破缺的尺度之间存在着一种特殊的关系。
We consider a novel class of constraints on chiral superfields to obtain supersymmetric nonlinear sigma models in four spacetime dimensions, which strictly combine the internal symmetry breaking with spontaneous supersymmetry breaking. The resultant massless modes can be exclusively Nambu–Goldstone bosons without their complex partners and the goldstino that is charged under the internal symmetry. The massive modes show a peculiar relation among their masses and the scales of symmetry breakings.
