论文摘要
提出了Feyngrav的软件包Feyngrav，以处理Feyncalc内的Feynman重力规则。我们提出了一个框架，以处理相对相对论和非对称物质的相应Feynman规则，最小化与重力耦合。包装的适用性通过2-> 2的壳树水平重力散射，偏振算子和一环标量 - 重大互动结构进行测试。
Package FeynGrav which provides a framework to deal with Feynman rules for gravity within FeynCalc is presented. We present a framework to deal with the corresponding Feynman rules for general relativity and non-supersymmetric matter minimally coupled to gravity. Applicability of the package is tested with 2 -> 2 on-shell tree level graviton scattering, polarization operators, and one-loop scalar-gravitational interaction structure.
