Re: SPHENO

Hi, SPheno is is a stand-alone program which calculates masses and decay properties of supersymmetric particles for some models. SARAH generalizes this to a wide range of models including non-supersymmetric ones. It generates a Fortran code which uses generic routines provided by the SPheno package....

Re: Model implementation in SARAH

Hi,
as far as I can see all the terms are given in the LRLR models which is one of the LRmodels. You can find the corresponding input files in the folder Models/LRmodels/LRLR

Re: Vector-like Lepton Model

Hello Kilian, per default all the spinors in SARAH are left-handed Weyl spinors to start with. This is one of the reasons why one has to add the conjugation at various places. Therefore I do not fully understand your second comment that vl1 and ve1 are right-handed. The warning about the mixing you ...

Re: Implementataion of Alternative Left right model

Hi,
you have to define a contraction struction like in the LRLR model which you can find in the Models directory.

Re: Model implementation in SARAH

Hi,
I do not understand \ \alpha_2 chi^{\dagger} \phi \phi^{\dagger}\chi and \alpha \chi^{\dagger}\tilde{\phi}^{\dagger}\tilde{\phi}\chi can be both LR invariant. What precisely do you mean by \tilde{\phi}^{\dagger} ?

Hi,

with the current implementation this not possible.

Re: Weird Higgs sector in linear seesaw model

Hi,

I presume that you are using the latest version of SARAH. Could you please let me know which Mathematica version you are using?

Re: MadAnalysis 5 not working with UFO from Sarah

Dear Pradipta,

I have tried a simple example myself and I did not encounter any problems but I have also a different python version. Which error messages do you get?

Best,
