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.
Validation
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).
Interfaces
This model implementation is known to work with the following interfaces:
