can not find |cu|, segmentation fault

1) Font problem
Open file calchep.ini and write

fontFamily *

2) Before you try to compile process, check your model. Use menu

    Edit Model
           Check Model.

You should get some error message.

I have written the couplings of this extra fermion with Z_R and also all the couplings of Z_R with the SM fermions. My model files are "ok" when I check them in calchep. I try to generate a process like X0,X0 -> u,U and I get the diagram with Z_R mediator. After squaring the diagram when I try to do "symbolic calculation" or "make&launch n_calchep", it does not do anything just that calculation in progress. If I quit the program at that stage I get:

Hi,

  Thanks for the reply but I am not so much worried about the font as other processes run without the correct font.

  My main problem is that the process is not running. I have checked the model file using the Edit Model -> Check Model and it says "Model is ok" but still it does not compile as I had written above. I am not sure if I am doing something wrong or if it is a bug in Calchep.

Thank you.

Best Regards,
Ayon

ok, send me your model.

Problem has been solved. I was using g(m*) instead of G(m*) in the lagrangian file. Thanks a lot Alexander.
