标题： A New Stability Equation for the Abelian Higgs-Kibble Model with a Dim.6 Derivative Operator

摘要： 我们证明，在阿贝尔希格斯-基布尔模型中，补充了一个六维导数算符的标量希格斯场的动力学，在量子层面上可以通过某个稳定性方程进行约束。该方程在朗道规范下成立，并且是在最近提出的扩展场形式中推导出来的，其中物理标量由一个规范不变的场变量描述。讨论了稳定性方程的物理含义。 显示英文摘要

摘要： We show that the dynamics of the scalar Higgs field in the Abelian Higgs-Kibble model, supplemented with a dimension 6 derivative operator, can be constrained at the quantum level by a certain stability equation. The latter holds true in the Landau gauge and is derived within the recently proposed extended field formalism where the physical scalar is described by a gauge-invariant field variable. Physical implications of the stability equation are discussed.
