Dear developers, I seem to have stumbled across a bug in FeynArts output. In feynarts.m there is a line setting the gauge parameter for Goldstone bosons: WriteString[outputfile,"GaugeXi[S["<>ToString[FeynArtsNr[PART[S][[i,1]]]]<>",1]] = GaugeXi["<>ToString[Select[GoldstoneBosons[InitalizedVertexCalc...

Sorry for the misunderstanding and thank you for pointing in the right direction! Turns out, that I had introduced typos in the block SMINPUTS, when making a scanning package...now it all matches nicely. Thanks again!

Regards,

Simonas

I have attached the model and thank you for having a look.

Hello,

I have downloaded the new version and included the new 19th flag but the deviation remains.
Maybe you could specify the special combination of flags so that I can try it out?

Hello, I have a question about comparing the input vs. output at tree level. What I have tried looking at is essentially the potential of the two Higgs doublet model in the Higgs basis. I do have some of the tree level expressions relating physical quantities to the input parameters at tree level. I...

Dear Florian, I did some more digging and in their code documentation they reference this paper: https://doi.org/10.1016/j.amc.2014.01.170 , which I could not access for free. I think that by using Takagi's factorization they are able to bypass actually having M^{Dagger}M, but they do get square roo...

Dear Florian, so in essence, the minimal mass of neutrinos in the complex case is limited by 10^(-30)*MR^2 instead of 10^(-30)*MR? I took a little peek at the code in FlexibleSUSY. As far as I can tell, it does not try to deal with asymmetric matrices. Specifically, only the upper triangle of the Mv...

Dear Florian, thank you for the fixes and looking into it! Though, I am still bumping into problems. I did replace the MathematicsQP.f90 file, the lines in TreeMasses_MODEL and recompiled everything. I no longer get NaNs, but with purely imaginary Yukawa I get this error: Calculating mass spectrum 1...

Thanks, it's nice to have a confirmation! However, I now return to problems of having complex neutrino Yukawa couplings...I am trying to implement a model with two Higgs doublets and heavy Majorana neutrino. I have attached the model files. I have edited the src/Makefile, recompiled SPheno and also ...

Dear Florian, I'll join in on questioning about QP precision. In the wiki it is said, that one needs to enable QP precision in the model file and I can't seem to find that statement anywhere else. Is it enough to delete the -DONLYDOUBLE flag and recompile, or should one also use, for example, Quadru...
