在有质量矢量场局域化机制中包含规范对称性

Including gauge symmetry in the localization mechanism of massive vector fields

Rommel Guerrero, R. Omar Rodriguez

摘要:

在AdS $_5$翘曲几何的四维扇区上,标准的电磁相互作用可以通过Ghoroku - Nakamura定域机制用大质量矢量场来模拟。我们将规范对称性,以这个理论,找到所需的相互作用项之间的矢量玻色子和引力场的情况。在大质量本征态的基础上展开矢量场,得到了由麦克斯韦项和斯图克伯格场塔定义的四维有效理论,其中零模与谱的其余部分解耦。计算了由静电势引起的质量规范场的修正。

英文摘要:

On the four-dimensional sector of an AdS$_5$ warped geometry the standard electromagnetic interaction can be simulated by massive vector fields via the Ghoroku - Nakamura localization mechanism. We incorporate gauge symmetry to this theory by finding the required interaction terms between the vector bosons and the gravitational field of the scenario. The four-dimensional effective theory defined by a Maxwell term and a tower of Stueckelberg fields is obtained after expanding the vector fields on a massive eigenstates basis where the zero mode is uncoupled from the rest of the spectrum. The corrections generated by the massive gauge fields set to the electrostatic potential are also calculated.
