tZ FCNC (BSM) model selection

Asked by Muhammad Shoaib

Hi Dears,

I am doing single top FCNC study (tZ fcnc) and getting confused in importing model for FCNC. I have ready many articles about tZ FCNC where mentioned UFO model with various PDFs sets and many others.

My naive question is, since there are many models which being used to generate tZ fcnc events using Madgraph so which should be adopted with what justification.

Since I have not knowledge of the model and who created such model.
I'm afraid that I can not help for that. My only advise is to read the paper/documentation to check what is inside each model and if you find one that include the physics that you are interested, you are good to go.
Many person have develop their own UFO model due to personal preference of convention/... So in such cases, they are not really a better UFO model.



Can you help with this problem?
