论文摘要
我们提出了Feyncalc 9.3，这是一个新的稳定版本，用于符号量子场理论（QFT）计算功能强大且多功能的Mathematica软件包。详细解释了一些有趣的新功能，例如与其他软件包的高度改进的互操作性，1循环积分的紫外线发散部分自动提取，对Majorana Fermions的振幅的支持以及具有明确的Dirac Indices的$γ$ -Matrices。此外，我们讨论了在包装的日常使用中可能引起的一些常见问题和误解，从而提供了解释和解决方法。
We present FeynCalc 9.3, a new stable version of a powerful and versatile Mathematica package for symbolic quantum field theory (QFT) calculations. Some interesting new features such as highly improved interoperability with other packages, automatic extraction of the ultraviolet divergent parts of 1-loop integrals, support for amplitudes with Majorana fermions and $γ$-matrices with explicit Dirac indices are explained in detail. Furthermore, we discuss some common problems and misunderstandings that may arise in the daily usage of the package, providing explanations and workarounds.
