通过推导两个双重态希格斯的真空期望值，构造了具有自破缺规范对称的超对称规范理论的非拓扑弦解。它是电弱弦的超对称延伸，而超对称是不破缺的。用微扰讨论了非拓扑弦的经典稳定性。我们证明了经典稳定性仅由两个参数决定，并且允许区域与电弱弦中的基本相同。
We construct a nontopological string solution for a supersymmetric gauge theory withgauge symmetry which is spontaneously broken toby developing the vacuum expectation value of two doublet Higgses. It is a supersymmetric extension of the electroweak string while supersymmetry is unbroken. We discuss the classical stability of the nontopological string by perturbations. We show that the classical stability is determined only by two parameters, and that the allowed region becomes essentially the same as in the electroweak string.
