matrix1.f: undefined reference to `aloha_m7450478851985516657_1_' in MG5

Asked by Abhaya Kumar Swain

Dear MG5 experts,

I have implemented my model file in the Feynrules and the UFO file is then used in MG5_aMC_v2_7_2. The process I generate is,

generate p p > b b~ chi chi

where chi is a new Majorana fermion in my model. When I import the model file, it initially shows the error regarding four fermion interaction but I have commented the corresponding line in the file "models/import_ufo.py" to ignore that error. After that I could import the model successfully but I am getting the following error after "launch",

Error detected in "generate_events "
write debug file /home/abhaya/Downloads/HEP_software/MG5_aMC_v2_7_2/bbBar_PlusMissingEnergy_HQGDM/run_01_tag_1_debug.log

Hi,

This type of function "aloha_m7450478851985516657_1_" is only generated as shortcut name for functions where the normal name would be very very long. The issue is likely related to that. I would need your UFO model in order to look at this in details.

Cheers,

Olivier

(PS you can not attach file to question, you can either sent th UFO model to my email --please put a link to this question-- or create a bug report where you can add attachment)

Hi,

Thanks for the model,

Here is a patch that fixed the (actually two) issues:

Hello,

Thank you very much for your quick response. The above patch was really helpful and it indeed fixed the error. But now I am getting another error,

Looks like your matrix-element always returns zero:
