    2124   * [/feynrules/attachment/wiki/StandardModel/Cabibbo.rst Cabibbo.rst]: 3rd generation mixing is off.
    2225=== Instructions ===
    23 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.
     26The 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. The NLO counterterms have been computed and can be found in the
     27[/attachment/wiki/StandardModel/SMQCD.nlo SMQCD.nlo]. They can be exported in the UFO format to Madgraph5/aMCatNLO.
    2428=== Examples ===
    2529   * [/attachment/wiki/StandardModel/SM.nb SM.nb]: This is an example Mathematica® notebook that loads SM.fr and calculates Feynman rules.
     
    2731=== Validation ===
    2832The SM implementation was extensively tested on various 2-to-2 processes. A selection is shown in [/attachment/wiki/StandardModel/XS1.jpg this table]. (Note that the discrepancy with MG stock simply comes from the fact that MG stock has the 4 higgs vertex not implemented).
     33The counterterms analytic expressions have been checked with the literature and the UFO compared with the built in version of SM in Madgraph5/aMCatNLO.
