Compilation error Mac

Dear Florian, We had some compilation errors on Mac (MacOS 10.13.6, gfortran 6.3.0, Xcode 9.4.1). The error message is /Applications/Xcode.app/Contents/Developer/usr/bin/make F90=gfortran ../lib/libSPhenoSUSY_EW_ISS.a gfortran -c -g -ffree-line-length-none -J../include -I../include Settings.f90 ar -...

Problem with SARAH 4.13.0/SPheno

Dear Florian, I was testing my models for the electrowek scale inverse seesaw with the new version of SARAH (it is on the model database https://sarah.hepforge.org/trac/wiki/inverse-Seesaw-SUSY-EW ). Now I have just created the output files as with SARAH 4.12.2 but suddenly the SPheno output does no...

Loop factor in LaTeX-output of self energies

Dear Florian, I hope nobody asked this question before but I could not find anything about it. So I apologise if this is already clarified somewhere else. I have the strong feeling that the notation used in the LaTeX output and your documentation is not quite consistent, i.e. there is a loop factor ...

Re: Feynman gauge vs. unitary gauge

Dear Florian,

Indeed you are correct. The problems my colleague mentioned occurred in the context of simplified models.

Sorry for bothering and thanks a lot,
Martin

Re: Feynman gauge vs. unitary gauge

Hi Florian, I am not totally sure about this. In the model we studied I could not yet find a point which differs. But one of my collaborators, who has much more experience with CalcHep and micromegas, had problems with this kind of conflict before. He said this is more obvious in Higgs observables a...

Feynman gauge vs. unitary gauge

Dear Florian, We were using SARAH to generate some CalcHep Output. We have used MakeChep[FeynmanGauge -> True]. The generated model files seem to be fine, but in the created *.cpp files there is the line ForceUG=1; This forces micromegas to use unitary gauge and the results are likely to be wrong. I...

I vs. i in TeXOutput

Hi, In our model we would like to label mixing matrices and fields with a capital 'I', e.g. {ZVI, { LaTeX -> "Z^I", OutputName -> ZVI, LesHouches -> ZVI }}, and {SvIm, { Description -> "CP-odd Sneutrino", LaTeX -> "\\tilde{\\nu}^{I}"}} Unfortunately in the TeX-file generated the capital 'I' ar repla...
