FeynGame 3.0

Abstract

A major update of the program FeynGame is introduced. One of its main new functionalities is to visualize Feynman graphs generated by qgraf . The qgraf output can be either pasted into the FeynGame canvas for individual graphs, or the whole qgraf output file can be processed. In addition, a number of new features and improvements have been implemented into FeynGame 3.0 in order to further facilitate the efficient drawing of Feynman diagrams in publication quality. FeynGame is freely available • as jar or MacOS app file from https://web.physik.rwth-aachen.de/user/harlander/software/feyngame • as source code from https://gitlab.com/feyngame/FeynGame PROGRAM SUMMARY Program Title: FeynGame 3.0 CPC Library link to program files: https://doi.org/10.17632/5bpp2w6ykd.1 Developer's repository link: https://gitlab.com/feyngame/FeynGame Licensing provisions: GNU General Public License 3 Programming language: Java Nature of problem: Efficient drawing of Feynman diagrams for presentations and publications; automatic visualization of computer-generated Feynman graphs [1]; playful elementary introduction to the concept of Feynman diagrams.
