Model Restrictions


The Standard Model (SM) is implemented in both Feynman and unitary gauge. A switch FeynmanGauge has been created. To switch between the two simply set FeynmanGauge = True/False inside your mathematica notebook after loading the model but before doing any calculations with it (finding vertices for example.) FeynmanGauge is set to False by default.


  • SM.nb: This is an example Mathematica® notebook that loads and calculates Feynman rules.


The SM implementation was extensively tested on various 2-to-2 processes. A selection is shown in this table. (Note that the discrepancy with MG stock simply comes from the fact that MG stock has the 4 higgs vertex not implemented).


This model implementation is known to work with the following interfaces:
