Dear Florian,

I have wrote an extension of SM in SARAH, which is working fine until "MakeCHep". It is showing some error with MakeCHep[ ] operation, which i could not make out. I have uploaded screenshot of the following. Please help me out.

Thanks,
Shivam Gola

Hi,

I don't see any screenshots. Unfortunately, a PHP update on the server has broken some features of the forum. Since it is going to move soon, I hesitate to reinstall everything. Sorry. Could you copy&past the error messages?

Cheers,
Florian

Hi, sorry for the inconvenience, i have copied the error message with some additional dialogues in beginning and end.

Hi,

does the model come with a second SU(3) ? That's not supported by CalcHep.

Cheers,
Florian

Ooo.... it comes with second SU[3].


Thanks,
