Dear Florian, I am writing a model having SM with a new singlet scalar and a fermion, and added all allowed couplings. I used MakeSPheno[], and trying to compile it, which ended with the following error dialogue- """" ar -ruc -U ../lib/libSPhenoMSM6.a Couplings_MSM6.o rm -f Couplings_MSM6.o gfortran...

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


Thanks,
Shivam

Hi, sorry for the inconvenience, i have copied the error message with some additional dialogues in beginning and end. """" Writing all vertices ... Generic class: SSS . Expanding and writing: 3/3 .

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.

Hi,

Thanks for the suggestions.

One more query. Is it possible to assign a different Z2 charges within SU(2) doublet in SARAH ?

Thanks,
Shivam

Thank You !

Dear All, As I have not had much experience with SARAH and not having any other SARAH user to discuss with. I want to implement an axion model(KSVZ). Is it possible to write such model which contain dimension five terms(axion-gluon, axion-photon coupling) ? Please help me in this regard. Thanks All,...

Hi, i am writing this here because i felt not to stated my problem properly. I have wrote a model = SM +Type I seesaw+ Z2 symmetry, such that only R-neutrino is odd under Z2. But this raise a problem of non-invariant of dirac neutrino mass term under Z2. Can i rescue this model without introducing a...

Dear Sir,

I have a wrote a model consisting SM and Type I Seesaw. I want to make right neutrino as Dark matter. How do tell micromega, without adding any new fields ?
I have attached the model folder with this mail. Please find it.

Hi, my problem is solved, i am using SARAH 4.14.1, so one need to change flag no.55 from 0 to 1 in Leshouche.in file.

Thanks you.
