Abstract

We consider SU(2) gauge theory with a scalar field in the fundamental representation. The model is known to contain electric field solutions sourced by the scalar field that are distinct from embedded Maxwell electric fields. We examine the perturbative stability of the solution and identify a region of parameter space where the solution is stable. In the regime where the scalar field has a negative mass squared, the solution has two branches, and we identify an instability in one of the branches.

非阿贝尔电场解的微扰稳定性

在基本表示中考虑带标量场的SU(2)规范理论。已知该模型包含由标量场产生的电场解，这些解与嵌入的麦克斯韦电场不同。我们检验了解的微扰稳定性，并在参数空间中确定了解稳定的区域。在标量场质量平方为负的情况下，解有两个分支，我们在其中一个分支中确定了不稳定性。2025年由美国物理学会出版
