Hi

I'm trying to calculate cross section of a process with a decay chain by using madspin. However it gives me the following error:

Error detected in "generate_events run_02"
write debug file /home/jack/packages/MG5_aMC_v2_4_0/chachabar/run_02_tag_2_debug.log
If you need help with this issue please contact us on https://answers.launchpad.net/mg5amcnlo
MadGraph5Error : h3 particles with pdg code 45 is in conflict with MG convention name for particle 36.
Use -modelname in order to use the particles name defined in the model and not the MadGraph5_aMC@NLO convention

The problem is I'm already importing the model by using 'import model $model --modelname' which generated by SARAH and masses and decay tables were calculated by SPheno with proper flags for madgraph. I also tried to run it directly from madspin itself instead of launching it from mg5, however it gave me the same error all the time. Is there any way to fix this?

Thanks

Best regards
Jack

Hi,

If it works without MadSpin then it seems to me to be a bug there, but not with the model. So, you should contact the authors. I won't be able to help with that.
Alternatively, you can search for the file which fixes the MG naming conventions and edit that by hand.

Cheers
