[Flexiblesusy] Find for a Complete List of Available Functions and Symbols in the Boundary Conditions

[Alexander Voigt]

Dear Song Li,

I'm afraid there is not jet an official exhaustive documentation of the
list of all symbols that can be used in the boundary conditions (BCs).
You may find some first guidance here:

https://github.com/FlexibleSUSY/FlexibleSUSY/blob/master/doc/model_file.rst

However, I can of course give you some additional guidance.  :)

The following symbols can be used in the all boundary conditions (of
course the names of the symbols depend on your particular model):

* any input parameter (TanBeta, m0, m12, ... for example in the CMSSM)
* any running model parameter (Mhh, MFu, MVZ, g1, g2, ...)
* any pole mass (Pole[Mhh], Pole[MVZ], ...)
* any derived parameter (ThetaW, VEV, ...)
* renormalization scale: SCALE
* beta function: BETA (see BetaSM example model file)
* GUT normalization factors, for example GUTNormalization[g1] etc.

In addition you can use in the low-scale constraint the symbols:

* MZPole (input Z pole mass)
* EMSbar, EDRbar (running electromagnetic gauge coupling in the model)
* THETAW (running theta_w in the model)
* CKM (input CKM matrix)
* PMNS (input PMNS matrix)
* running fermion masses in the model: upQuarksDRbar, downQuarksDRbar,
  downLeptonsDRbar, neutrinoDRbar

One can infer the list of available symbols from the C preprocessor
definitions in templates/two_scale_low_scale_constraint.cpp.in etc.

In addition you can use large expressions of all of the above paramters.
For examples you can have a look at the following models:

  model_files/MSSMNoFV/FlexibleSUSY.m.in
  model_files/HSSUSY/FlexibleSUSY.m.in

I'm not sure what you are trying to do, but if you are more specific I
can give you some more hints or examples.  :)

Best regards
Alexander Voigt

P.S.: The FlexibleSUSY mailing list is not used so frequently,
unfortunately.  If you like, you can also ask a question on github,
which will be checked by all of the FlexibleSUSY developers more regularly.
