Create a New Model File for UMSSM writing all extra charges in terms of a new parameter

[felipeagf]

Hello Florian

I am studying the general U(1) Extension of MSSM called UMSSM already implemented in SARAH-4.9.3. This model has some charges related to the extra U(1) symmetry which appears as 9 Extra parameters in the parameters.m file of the model. I would like to create a new model file where these charges are all written in terms of a mixing angle ¨ThetaE6¨ that mixes the 2 U(1) symmetries U(1)' = cosθE6 U(1)χ + sinθE6 U(1)ψ as this is the case that appears in E6-Extended SUSY models after breaking E6 symmetry into SU(3) X SU(2) X U(1) X U(1)'.

I wrote in the model file of this model all the U(1)' charges as functions of the mixing angle ThetaE6. This seemed to be accepted by SARAH.
But when I run SARAH, it says that there is an Unknown keyword Latex in parameter file after the Initialization process. In the parameter file I defined the mixing angle ThetaE6 as a new parameter and wrote for all the U(1)' charges their corresponding expressions in terms of the mixing angle using DependenceNum ->. In the Checking model files operation, SARAH says that the Parameter file is buggy and says also that there is an UnknownKeywordParameter, but SARAH does not write this Unknown Keyword Parameter. How can I find it?

I attached here the original parameter file of UMSSM together with the model file with my modifications and the results shown by SARAH in my screen.


Thank you!!!

Hi,

according to your screenshot, it complains about the keyword Latex what should read LaTeX.

Hi Florian

When I run the command CheckModel[] in SARAH with my modified model files, SARAH shows a Mathematica warning in the operation called "Checking particle definitions for GaugeES". In Transpose::nmtx, it says that "The first two levels of {} cannot be transposed". In General::stop, it says that "Further output of Transpose::nmtx will be suppressed during this calculation". Is there a way to solve this problem in such a way that these error messages will not appear again?

The particle file and the screen image that shows this error messages are attached here.

Thank you
