FeynOnium is a FeynCalc add-on that facilitates calculations in Nonrelativistic Effective Field Theories (NREFTs) in particular Nonrelativistic QCD (NRQCD) and potential Nonrelativistic QCD (pNRQCD)
FeynOnium is designed as an add-on for FeynCalc. To use it you need at least FeynCalc 9.3 and Mathematica 8. Many of the supplied examples also require the FeynHelpers(https://github.com/FeynCalc/feynhelpers) add-on.
