Modification of "Stueckelberg-MSSM" Model in SARAH to Include FI Terms
Posted: 20. Sep 2020, 08:01
Hello,
I (and a colleague) have been trying to modify the model "Stueckelberg-MSSM" in SARAH to include FI terms. (The existing model only works for the case FI parameters are not included and it seems to skip some terms including \Xi* s M which has an important role, in case FI terms are included .)
The way I could think of was to turn D-terms off and add them in terms of component fields to the model. There is a linear term in the lagrangian though : M1ar Xi[Bp] (Ss+conj[Ss]) , adding which causes () and {} to appear in the outputs and leads to errors in deriving vertices. I am attaching my files. I will be truly thankful if you help me with getting rid of this error and if there is a better way to implement this modification to "Stueckelberg-MSSM"(in particular can the auxiliary part of vector superfield be included in lagrangian? )
Best regards
