Main_Model_File

Main Model File

General

The main model file is the most important piece of information about an implemented model SARAH: it contains all information about the particle content, the local and global symmetries, and about the interactions.

Head of the model file

At the very beginning of a model file, some additional information about the model implementation can be given: what’s the name of the model (in LaTeX syntax as well as string without any special character), who is the author of the model file and when was the last change:

Model`Name = "BLSSM";
Model`NameLaTeX ="B-L-SSM";
Model`Authors = "L.Basso, F.Staub";
Model`Date = "2012-09-01";

Definition needed for the gauge eigenstates

  1. Global symmetrie are defined in an array Global, see Global Symmetries SUSY and Global Symmetries non-SUSY
    Global[[/1|1]] = {...

  2. Gauge structure of the model given by the vector superfields, see Gauge Symmetries non-SUSY and Gauge Symmetries SUSY
    Gauge[[/1|1]] = {...

  3. Matter content given by either chiral superfields, see Particle Content SUSY
    SuperFields[[/1|1]] = { ...
    or fermion and scalar fields for non-SUSY models, see Particle Content non-SUSY

  5. Gauge fixing terms: since version 3.1 no longer needed as input, see Gauge fixing

  6. Additional couplings or redefinition of existing couplings, see Additional terms in Lagrangian
    DEFINITION[$EIGENSTATES][Additional]= { ...

  7. Definition of Dirac spinors, see Dirac Spinors
    DEFINITION[$EIGENSTATES][DiracSpinors]= { ...
