论文摘要
我们提出了一个新版本的Pyr@te，这是一种用于计算一般非苏格米对称仪表理论的重新归一化组方程的Python工具。它的新核心依赖于Poole＆Thomsen（Arxiv：1906.04625）最近的一篇论文来计算$β$ - 功能。在此框架中，量规动力学混合是自然实现的，并且仪表，四分之一和Yukawa耦合之间的Weyl一致性关系自动满足。主要的新功能之一是用户可能将量规耦合到三环订单的量规耦合。 PYR@TE代码的大部分已被改写和改进，包括组理论模块Pylie。结果，计算速度方面的总体性能得到了极大的提高，模型文件更加灵活和用户友好。
We present a new version of PyR@TE, a Python tool for the computation of renormalization group equations for general, non-supersymmetric gauge theories. Its new core relies on a recent paper by Poole & Thomsen (arXiv:1906.04625) to compute the $β$-functions. In this framework, gauge kinetic mixing is naturally implemented, and the Weyl consistency relations between gauge, quartic and Yukawa couplings are automatically satisfied. One of the main new features is the possibility for the user to compute the gauge coupling $β$-functions up to the three-loop order. Large parts of the PyR@TE code have been rewritten and improved, including the group theory module PyLie. As a result, the overall performance in terms of computation speed was drastically improved and the model file is more flexible and user-friendly.
