Model Files

• SM.fr​: This is the main file.

Model Restrictions

• ​Massless.rst: Only the top, bottom and charm quarks, and the tau lepton are massive.
• ​DiagonalCKM.rst: The CKM maktrix is diagonal.
• ​Cabibbo.rst: 3rd generation mixing is off.

Instructions

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.

Examples

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