| Jul 23, 2018 at 7:37 | comment | added | vsht | @Rohan As far as diagram generators are concerned, there are no other Mathematica packages than FeynArts. Many people also use QGRAF, but this Fortran code lacks a GUI or even a diagram plotter and is more difficult to use than FeynArts. As for FeynCalc-like packages, have a look at HEPMath (hepmath.hepforge.org) and Package-X (packagex.hepforge.org). AFAIK HEPMath is not actively developed anymore, but the last release was not so long time ago, so it should still work with the recent Mathematica versions. Package-X is still actively developed, but it has no interface to FeynArts. | |

Thanks for the Advice @Mr.Wizard. In addition, can you name any such packages for Mathematica other than FeynArts or FeynCalc for High Energy Physics for calculating Cross Sections and other relevant details?

@Rohan As I said I am not surprised; the package may require a complete rewrite for contemporary versions of Mathematica. Among many other things NonCommutativeMultiply is now a built-in function and not necessarily compatible with the package Symbol of the same name; you may need context manipulation to get around this. Honestly if you can find an alternative to using this package I recommend you do so, as it may be a lot of work for you otherwise.

The error message is suppressed but the problem remains whenever anything related to Spinor.m is encountered. @Mr.Wizard
