FeynGraph - A Modern High-Performance Feynman Diagram Generator — •Jens Braun — Institute for Theoretical Physics, Karlsruhe Institute of Technology

We present FeynGraph, a modern high-performance Feynman diagram generator designed to integrate seamlessly with modern computational workflows to calculate scattering amplitudes. FeynGraph is designed as a high-performance Rust library with easy-to-use Python bindings, allowing it to be readily used in other tools. With additional features like arbitrary custom diagram selection filters and automatic diagram drawing, FeynGraph strives to be a fully-featured Feynman diagram toolkit at any loop order.
