Hello, I have encountered a case where, in a model with two real SU(2) triplets, I get the error RGEs::StillEntangled during MakeSPheno[]. I have attached a minimal test case where two real triplets are simply added to the Standard Model (similar to SM+Triplet/Real). Here are the error messages: RGE...

I’ve been trying to make files for a model with multiple generations of inert real triplet scalars, but depending on the names I choose for the mixing matrices in the model files, I get some strange compiler errors when compiling SPheno. The basic setup looks like this (but also see the attached mod...

I’ve been trying to implement a model with multiple generations of a real scalar “phi”, which leads to a parameter with four indices if the quartic self-interaction LagNoHC = … - λ4 phi.phi.phi.phi; is included. The corresponding SPheno source code created by MakeSPheno[] yields compiler errors with...

Of course, Dirac and Majorana neutrinos are different. But the spinor Fv -> {vL, 0} doesn’t really describe a Dirac fermion – it’s just a Weyl spinor disguised in the four-component spinor formalism. Using the correct translation (gamma matrices instead of Pauli matrices etc.) to the four-component ...

In the included model files for the Standard Model (model “SM”), the Dirac spinor for the neutrinos is defined as DEFINITION[EWSB][DiracSpinors]={ … Fv ->{ vL, 0}}; In models with radiative neutrino masses (e. g. the scotogenic/radiative seesaw model), it should be possible to use a nonzero value fo...

Running any SARAH-generated SPheno version produces a file called “Messages.out” containing some warnings. For example, for the SARAH model SM+Triplet/Real, running “bin/SPhenoTSM LesHouches.in.TSM” gives sugra 1 .-iteration sugra 2 .-iteration Problem in Function B0, divergence for k->0, m1=m2=0 Pr...

I just ran into this issue and honestly, I consider it to be very dangerous that the SPheno version generated by SARAH silently reads incorrect values from the SLHA input files if not every line follows the format “index, value, comment”, especially since this isn’t documented anywhere! This does no...

Hi, it seems that this is another case where the possibility of negative masses wasn't thought of, i.e. Abs() missing again. I don't have time right now to run it my own, but I guess the patch in the attachment should work... if not, please come back. Cheers, Florian It seems to work now – thanks a...

Hi, the problem was that it tried to take the log of a negative mass. I have added the missing abs(). The patch is attached. In addition, I think you should also change your model and add a phase for your vector-like states: DEFINITION[EWSB][Phases]= { {doub1p, PhaseD} }; Otherwise, you'll see that...

In the file CalcOmega.cpp generated by SARAH, there is the line “ForceUG = 1;”. It seems that that’s supposed to mean “force unitary gauge”, but where does that actually make a difference? Do we have to set ForceUG = 1 for micrOMEGAs model files generated by SARAH? Unfortunately, I couldn’t find any...
