| 15 | === Model Restrictions === |

| 16 | * [http://europa.fyma.ucl.ac.be/~duhr/twiki/pub/Main/StandardModel/Massless.rst Massless.rst]: Only the top, bottom and charm quarks, and the tau lepton are massive. |

| 17 | * [http://europa.fyma.ucl.ac.be/~duhr/twiki/pub/Main/StandardModel/DiagonalCKM.rst DiagonalCKM.rst]: The CKM maktrix is diagonal. |

| 18 | * [http://europa.fyma.ucl.ac.be/~duhr/twiki/pub/Main/StandardModel/Cabibbo.rst Cabibbo.rst]: 3rd generation mixing is off. |

| 19 | === Instructions === |

| 20 | |

| 21 | 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. |

| 22 | === Examples === |

| 23 | * [http://europa.fyma.ucl.ac.be/~duhr/twiki/pub/Main/StandardModel/SM.nb SM.nb]: This is an example Mathematica® notebook that loads SM.fr and calculates Feynman rules. |
