论文摘要
在Abelian Higgs模型中，外部电荷（和电流）的电气（和电流）由标量场筛选。在这项贡献中，对Ishihara和Ogawa的最新研究进行了补充，我们提出了使用扰动方法以电荷强度作为扩展参数的扰动方法进行详细研究。它显示了如何从高斯定理中得出完美的全球和非常好的本地筛选，以及远离来源的领域的渐近形式。扰动结果显示出与数值相比的比较。
In the Abelian Higgs model electric (and magnetic) fields of external charges (and currents) are screened by the scalar field. In this contribution, complementing recent investigations of Ishihara and Ogawa, we present a detailed investigation of charge screening using a perturbative approach with the charge strength as an expansion parameter. It is shown how perfect global and remarkably good local screening can be derived from Gauss' theorem, and the asymptotic form of the fields far from the sources. The perturbative results are shown to compare favourably to the numerical ones.
