论文摘要
在这项工作中,我们介绍了使用动量空间技术的ADS $ _ {D+1} $环路振幅的系统研究。受树级计算中最新进展的启发,我们构建了一个差分运算符,该操作员可以对标量因子起作用,以生成gluon和graviton循环集成:这使任何给定的循环级别witten图的计算系统化。然后,我们在这种形式主义中提供一般处方,并讨论泡沫,三角形和盒子图。
In this work we present a systematic study of AdS$_{d+1}$ loop amplitudes for gluons and gravitons using momentum space techniques. Inspired by the recent progress in tree level computation, we construct a differential operator that can act on a scalar factor in order to generate gluon and graviton loop integrands: this systematizes the computation for any given loop level Witten diagram. We then give a general prescription in this formalism, and discuss it for bubble, triangle, and box diagrams.
