翘曲空间中零模的中间尺度顶点修正
Intermediate-scale vertex corrections for zero mode in warped space
摘要：
本文研究了具有弯曲额外维的非阿贝尔规范理论作为一种中间尺度的量子场论，这种中间尺度被认为远低于几何稳定化和普朗克尺度。零模顶点的环路修正可以在中间尺度的微扰中图解计算。每个图的贡献可以与四维理论中的对应图进行比较。结果发现，对于一部分的贡献的系数的对数标度具有相同的值的四维结果。本文还讨论了处理高维算子修正的观点。
英文摘要：
Non-Abelian gauge theory with a warped extra dimension is studied as a quantum field theory at an intermediate scale that is regarded as being much lower than the scale of the geometry stabilization and the Planck scale. Loop corrections for zero-mode vertices are diagrammatically calculable in perturbation at the intermediate scale. The contribution for each diagram can be compared to the correspondent in the four-dimensional theory. It is found that for a part of the contributions the coefficient for the logarithmic scaling has the same value as the four-dimensional results. A viewpoint to treat corrections associated with higher-dimensional operators is also discussed.
