[Category:FlavorKit](/Category:FlavorKit "wikilink") FlavorKit involves several public codes. We proceed to describe how to download and install them.
|
|
|
|
|
|
1. **FeynArts /FormCalc**
|
|
|
FeynArts and FormCalc can be downloaded from
|
|
|
`www.feynarts.de/`
|
|
|
|
|
|
It is also possible to use the script `FeynInstall`, to be found on the same site, for an automatic installation.
|
|
|
|
|
|
2. '''SARAH and PreSARAH '''
|
|
|
SARAH can be downloaded from
|
|
|
`sarah.hepforge.org/`
|
|
|
|
|
|
No installation or compilation is necessary. Both packages just need to be extracted by using `tar`.
|
|
|
|
|
|
> tar -xf SARAH-4.2.0
|
|
|
> tar -xf PreSARAH-1.0.0
|
|
|
|
|
|
`PreSARAH needs the paths to load FeynArts and FormCalc. These have to be provided by the user in the file PreSARAH.ini `
|
|
|
|
|
|
FeynArtsPackage = "FeynArts/FeynArts.m";
|
|
|
FormCalcPackage = "FormCalc/FormCalc.m";
|
|
|
|
|
|
|
|
|
This would work if FeynArts and FormCalc have been installed in the `Application` directory of the local Mathematica installation. Otherwise, absolute paths should be used, e.g.
|
|
|
|
|
|
FeynArtsPackage = "/home/$user/$path/FeynArts-3.7/FeynArts.m";
|
|
|
FormCalcPackage = "/home/$user/$path/FormCalc-8.1/FormCalc.m";
|
|
|
|
|
|
|
|
|
3. **SPheno** : SPheno can be downloaded from
|
|
|
spheno.hepforge.org
|
|
|
|
|
|
After extracting the package, `make` is used for the compilation.
|
|
|
|
|
|
> tar -xf SPheno-3.3.0.tar.gz<
|
|
|
> cd SPheno-3.3.0
|
|
|
> make
|
|
|
|
|
|
