ValueError : String ... cannot be simplified to a number!
I'm testing a new model (two universal extra dimensions from FeynRules UFO output) in MG5 and am running into errors with my QED interactions and the command output. Some of the errors include:
Another error I get is for the process: p p > t t~ t t~ QCD=6 QED=6 ,
INFO: Generating Helas calls for process: g g > t t~ t t~ QED=6 QCD=6
Command "output pp_ttbarttbar" interrupted with error:
ValueError : String 1/4 Nc^2 T(-1000,3) T(-1000,6) cannot be simplified to a number!
I've attached the debug file as MG_debug_2 in the MG_debug.tgz file.
I haven't had any problems with QCD processes, so I'm not sure if this is my model or a bug.
For the process, p p > e1p+ e1p- where e1p is an essentially a heavier electron I get the following errors when I invoke the command: output pp_e1pe1p
ALOHAERROR : unknow type in Lorentz Evaluation
I've attached the MG_debug file as MG_debug_1 in the MG_debug.tgz file.
Thanks for any assistance!!
