摘要:

在不久的将来,随着来自世界各地不同实验的数据量的迅速增加,超标准模型研究将变得越来越重要。BSM模型的全面研究通常是一项非常耗时的任务,涉及长时间和困难的计算。实际上,在这些模型中手工进行详尽的预测是不可能的,特别是如果想要用数据和SM进行统计比较的话。在这里,我们提出了MARTY(现代人工理论物理学家),一个新的C++框架,完全自动化计算从拉格朗日到物理量,如振幅或横截面。这个框架可以完全简化,自动和象征性的,物理量在一个非常大的各种各样的模型。MARTY还可以计算有效理论中的Wilson系数。这将极大地促进BSM模型在风味物理中的研究。与该领域现有的公共代码相反,MARTY旨在为研究预测BSM模型的高能物理学家提供一个独特的,免费的,开源的,强大的和用户友好的工具,有效或完整的理论高达1-loop级别,不依赖于任何外部软件包。通过几行代码,可以收集最终的表达式,这些表达式可以进行数值计算以进行统计分析。像自动生成和手动编辑费曼图,全面的手册和文档,清晰和易于处理的用户界面等功能都是MARTY的显着特点。

英文摘要:

Studies Beyond the Standard Model (BSM) will become more and more important in the near future with a rapidly increasing amount of data from different experiments around the world. The full study of BSM models is in general an extremely time-consuming task involving long and difficult calculations. It is in practice not possible to do exhaustive predictions in these models by hand, in particular if one wants to perform a statistical comparison with data and the SM. Here we present MARTY (Modern ARtificial Theoretical phYsicist), a new C++ framework that fully automates calculations from the Lagrangian to physical quantities such as amplitudes or cross-sections. This framework can fully simplify, automatically and symbolically, physical quantities in a very large variety of models. MARTY can also compute Wilson coefficients in effective theories. This will considerably facilitate the study of BSM models in flavor physics. Contrary to the existing public codes in this field MARTY aims to give a unique, free, open-source, powerful and user-friendly tool for high-energy physicists studying predictive BSM models, in effective or full theories up to the 1-loop level, which does not rely on any external package. With a few lines of code one can gather final expressions that may be evaluated numerically for statistical analysis. Features like automatic generation and manual edition of Feynman diagrams, comprehensive manual and documentation, clear and easy to handle user interface are amongst notable features of MARTY.
