Dear SARAH developers,

Short comment to Alex's report.The reason why doesn't crash is because the wrong model gets loaded (MSSM instead or MSSMCPV) Regards,

Hi Florian, I'm continuing to experiment with SPheno versions with CKM matrix. What I observe is that whether or not of diagonal (tree-level) decays work is connected with the order of fields in the Yukawa interactions. Take for example the build in SM. The Yukawa terms there are LagHC = -(Yd conj[H...

Hi,

There doesn't seem to be any difference between v4.12.3 and 4.13.0 in that respect. Both files say cheers,
Wojciech

Hi Florian, We're currently trying to reproduce a result from literature for the mu to e conversion using FlavorKit. Unfortunately, without success. Therefore we started looking inside the code to pin point the difference. Would be great if you could clarify some points about the internals of Flavor...

Hi,

As always, thanks a lot for help. That solved my problem.

cheers,
Wojciech

Hi Florian,

Is it possible to get from SPheno loop-induces decays that go through a CKM matrix? Somethink like t -> c h? If so, can you point me to an example as it seems that none of CKM subfolders in Models directory contain a SPheno steering file.

Regards,
Wojciech

Hi Florian, Sorry about that (and also about a very late reply). I got confused because I didn't notice that you've used the Gordon identity to express operator with \sigma by the one with a scalar product. Now, if I look how OA2lSL and OA2lSR are calculated you set all the diagrams which are tagged...

Hi Florian, We're looking now into the mu -> e gamma process, which goes through operators you call OA2lSL and OA2lSR. As an example, the left one is defined in FlavourKit as {OA2lSL,Op[6] Pair[ec[3],k[1]]} If I compare it with footnote 9 in your paper 1405.1434 I would expect sth like {OA2lSL,Op[-6...

Hi Florian, I have a question about how the parameters are run to the scale at which the low energy observables are computed. In CalculateLowEnergyConstraints subroutine you first run to the top scale and calculate quark-related observables. Then you run to the mZ to do the same for the lepton ones....

Hi Florian, The generation indices inside of the ScatteringEigenvalues subroutine are undefined. Maybe some for loops are missing? Here's an example error message SPhenoMRSSM.f90:4662:45: scatter_matrix(155,685) = (-(g1**2*Delta(gen1,gen2)*Delta(gen3,gen4)) - g2**2*Delta(gen1,gen2)*Delta(gen3,gen4))...
