GKZ系统的$l$ -圈香蕉振幅和相对Calabi-Yau周期

The $l$-loop Banana Amplitude from GKZ Systems and relative Calabi-Yau Periods

Albrecht Klemm, Christoph Nega, Reza Safari

摘要:

我们使用GKZ描述的周期和某些类的相对周期的家庭的Barth-Nieto Calabi-Yau $(l-1)$折叠,以解决$l$环香蕉振幅与其一般的质量依赖性。作为例子,我们计算香蕉振幅的质量依赖性的三个回路的情况下,并检查结果对特定的质量值的已知结果。

英文摘要:

We use the GKZ description of periods and certain classes of relative periods on families of Barth-Nieto Calabi-Yau $(l-1)$-folds in order to solve the $l$-loop banana amplitudes with their general mass dependence. As examples we compute the mass dependencies of the banana amplitudes up to the three-loop case and check the results against the known results for special mass values.
