Hi, We are trying to run SM-CKM model in SARAH. This model file is running without error in Mathematica. But once we do MakeUFO, it displays that "{vu, vd} parameter is not defined in the parameter.m". It would be very much helpful if any one points out where is the error or we are missing something...

Hello Florian Sorry for the question which is probably trivial. I am interested in relic Density in micrOMEGAs and I have a problem about DirectDetection files. I want to use your MSSM files for relic density calculation in micrOMEGAs To use direct Detection and I type "make main=CalcOmega_with_DDet...

Hi Florian,

Using SARAH, how can one check for gauge coupling unification in case of mSUGRA models with very large universal scalar mass m_0?

Thanks in advance,
Amin

We are trying to build a new non-SUSY model with SARAH/SPheno with three Higgs doublets and we have encountered a problem which we couldn’t resolve ourselves. Basically, when we run our model file and generate TeX repository with SARAH, it works absolutely fine without any error messages whatsoever....

Dear Florian, I am trying to find the coupling value of a four-point vertex which contains all scalars. I am using MakeCHep[] to create a lgrng1.mdl file which contains the list of vertices. I am trying to follow the instructions as written in in the manual ( https://arxiv.org/pdf/1503.04200.pdf ) p...

Hello Florian Staub, Sorry to bother you, I am currently working in an implementation of a new model in SARAH (excelent tool by the way) but i was facing an issue that i was not able to work out. In fact i find the same Warning when i run the NMSSM model, the one that comes with the program. If i ru...

Dear Florian, I would like to ask your comments on the internal behaviour of SARAH/SPheno which is not perfectly clear to me concerning the renormalisation procedure with high energy boundary conditions. I will take as an example the MSSM generated by SARAH 4.9.3. If I have understood correctly, the...

Hi Florian, We face another trouble with U(1)_Dark extension implementation in SARAH. It seems that the calcHEP model file generated by SARAH is giving different results for SM Higgs decay width into Z ZD (ZD = dark photon) channel (i.e. h_SM ---> Z ZD) with and without enabling the unitary gauge ch...

Hi Florian, I am wondering how exactly SARAH is interpreting conj[...] when writing non-supersymmetric model files. It is not clear to me if this is hermitian or charge conjugation, and I have seen contradictory examples. Furthermore, even if it was clear which operation is implied by conj[] , the q...

Hi Florian, I am trying to write the code for SPheno using SARAH, however I was wondering if it is possible to input using pMSSM type boundary conditions in the high scale model. Specifically, to decouple the first and second generation soft scalar masses from the third generation to input them at a...
