论文摘要
我们使用$ su(2)\ times u(1)$计对象构建了非对称仪表理论的非容器弦乐解决方案,该解决方案是通过开发两个Doublet Higgses的真空期望值来自发地分解为$ u(1)$的。这是静电串的超对称延伸,而超对称不间断。我们通过扰动讨论了非流行字符串的经典稳定性。我们表明,经典稳定性仅由两个参数确定,并且允许的区域基本上与Electroweak字符串相同。
We construct a non-topological string solution for a supersymmetric gauge theory with $SU(2)\times U(1)$ gauge symmetry which is spontaneously broken to $U(1)$ by 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 non-topological string by perturbations. We show that the classical stability are determined only by two parameters, and that the allowed region becomes essentially the same as in the electroweak string.
