GoSam 2.0:在标准模型内和之外自动进行单回路计算

GoSam 2.0: Automated one loop calculations within and beyond the Standard Model

Nicolas Greiner

摘要:

我们提出了GoSam 2.0,一个全自动的框架,用于在多腿过程中生成和评估一个循环的振幅。新版本在代方面以及减少方面都提供了许多改进。这导致在标准模型内和之外的计算的更快和更稳定的代码。此外,它还包含Monte Carlo程序的标准化接口的扩展版本,可以与其他现有工具轻松组合。我们简要地描述了概念的创新,并提出了一些唯象的结果。

英文摘要:

We present GoSam 2.0, a fully automated framework for the generation and evaluation of one loop amplitudes in multi leg processes. The new version offers numerous improvements both on generational aspects as well as on the reduction side. This leads to a faster and more stable code for calculations within and beyond the Standard Model. Furthermore it contains the extended version of the standardized interface to Monte Carlo programs which allows for an easy combination with other existing tools. We briefly describe the conceptual innovations and present some phenomenological results.
