Nonrelativistic EFT description are planned for the future. Strong interactions of heavy quarks, extensions to other systems that admit a Operations that are common in nonrelativistic EFT calculations are implemented This is achieved byĮxploiting the novel features of FeynCalc that support manipulations ofĬartesian tensors, Pauli matrices and nonstandard loop integrals. Next you extract those files and place the folder HighEnergyPhysics in the subdirectory AddOns/Applications of the Mathematica tree. Documentation integrated into Mathematicas Documentation Center. Now, if B is just a shortcut for a tensor made out of products of 4-vectors and metric tensors, things become. Uncontract B LorentzIndex mu, LorentzIndex mu, Momentum W, W, Pair -> All Otherwise you could also omit DeclareFCTensor. Nonrelativistic EFTs (NREFTs) at tree- and 1-loop level. Then you go to the FeynCalc site and download the zip file that is compatible with your Mathematica version. Notice that DeclareFCTensor is only needed if you also want to be able to uncontract the indices as in. Have created a powerful framework for automatizing calculations in Building upon FeynCalc, anĮxisting Mathematica package for symbolic evaluation of Feynman diagrams, we Nonrelativistic Effective Field Theories (EFTs). Purpose software toolkit for semi-automatic symbolic calculations in Authors: Nora Brambilla, Hee Sok Chung, Vladyslav Shtabovenko, Antonio Vairo Download PDF Abstract: We present new results on FeynOnium, an ongoing project to develop a general
