论文摘要
我们通过其Mellin-Barnes代表来解决Multiloop Feynman积分的评估问题。在简要介绍了可用功能的开源工具包及其在各种情况下的应用程序之后，我们引入了一个新的代码mbcreate，该代码允许人们自动推论出一个简洁的Mellin-Barnes代表，以获得给定的参数积分。提供了有关其实施和使用的详尽讨论。
We address the problem of evaluation of multiloop Feynman integrals by means of their Mellin-Barnes representation. After a brief overview of available capabilities though open source toolkits and their application in various circumstances, we introduce a new code MBcreate which allows one to automatically deduce a concise Mellin-Barnes representation for a given parametric integral. A thorough discussion of its implementation and use is provided.
