反常三规范玻色子耦合的注记

Remarks on an anomalous triple gauge boson couplings

Patricio Gaete, J. A. Helayël-Neto, L. P. R. Ospedal

摘要:

我们解决了一个异常的三重规范玻色子耦合的标准模型的电弱部门的物理观测的效果,当$SU(2)_{L}\otimes U(1)_{Y}$对称性自发破缺的希格斯机制$U(1)_{em}$。我们的计算是在规范不变的框架内进行的,但路径依赖的变量形式主义,这是替代的威尔逊圈的方法。结果表明,相互作用能是一个Yukawa势和一个线性势之和,导致静态探针电荷的禁闭。然而,我们要强调的一点是,反常的三重规范玻色子耦合($Z γγ$)对核内尺度上的距离限制有贡献。

英文摘要:

We address the effect of an anomalous triple gauge boson couplings on a physical observable for the electroweak sector of the Standard Model, when the $SU(2)_{L}\otimes U(1)_{Y}$ symmetry is spontaneously broken by the Higgs mechanism to $U(1)_{em}$. Our calculation is done within the framework of the gauge-invariant, but path-dependent variable formalism which is alternative to the Wilson loop approach. Our result shows that the interaction energy is the sum of a Yukawa and a linear potential, leading to the confinement of static probe charges. The point we wish to emphasize, however, is that the anomalous triple gauge boson couplings ($Z γγ$) contributes to the confinement for distances on the intranuclear scale.
