CalcHEP

Feyn Rules model, error code 139

Asked by Ekaterina

Hello, dear CalcHEP experts!
We created a new model in FeynRules. This model contains a new scalar particle. This particle must decay into two positrons and gamma. Charge conjugation was explicitly introduced into the model Lagrangian.
Next, I use the WriteCHOutput command to create a model file for calchep. However, when importing the model into calchep, I noticed that the funcX.mdl and lgrngX.mdl files are empty. However, two more files are created in the mdl1 and mdl2 formats (for example, funcX.mdl1, funcX.mdl2). If you use these files instead of funcX.mdl, and run CHECK MODEL, then an error will appear
30744 Segmentation fault (core dumped) $CALCHEP/bin/s_calchep $*
CalcHEP has finished with error code 139
The Lagrangian entered in FeynRules is as follows
Lag = X1 anti[CC[e]].(a1 + b1 Ga[5]).e + HC[ X1 anti[CC[e]].(a1 + b1 Ga[5]).e ] - ee ebar.Ga[mu].e.A[mu]
What needs to be done to make this model work?
Thank you!
With the best regards, Ekaterina!

Dear Ekaterina,

please send your model files to <email address hidden>

as well as let me know your Lagrangian.

Regards,

Alexander
