Comment 3 for bug 1829266

Thanks you for helping me out Oliver,

I am fairly new to this game so excuse the dumb questions that follows:

1. "your quark/antiquark are in the correct 3/3bar representation."

what do you exactly mean by this? Are you referring to SU(3) irreducible representation? Do I have control over quarks representations in the model file? How can I correct this (if it is wrong)

2. "While your model name is inside our web database of model, I'm not able to generate your process and your param_card does not match the one expected for the online model."

Yes I used the DMsimp_s_spin1 model, but I have made some changes to this model. My model file is attached this message.

3. " But the problem is likely within your model definition where the colour structure of the u u~ g vertex is not correct. Can you check it?"

I do not know to modify colour structures of u u~ g in model file. I thought it is being imported from SM model. How can I check that? Where to look for this definition?

4. When I import model sm and do "display interactions u u~ g" I get the same message as you do. but when I also import my model file ie. DMsimp_s_spin1_UFO, I get:
"No matching for any interactions"
Now what does that mean? What can be done to resolve this?

5. "Also do you have warning about colour structure when loading your model?"

loading my model to where? If you mean Mathematica, then the answer is no, I do not see any message related to colour. If you mean MadGraph, then the answer is also no. This is the only message I get when I import my model to Madgraph after I imported sm model to it:

Thank you,
