Re: Interactions violating the charge

Thanks for your reply.
I can't find detailed debug info of MG.
Maybe I should ask MG team to offer.
Best Wishes!

what's the meaning of "dummy value"?

Dear Florian, Sometimes, I use the command: WriteTemplatesParFiles[] to write the particles.m or parameters.m, but I get the following information in the particle.m.template. ElectricCharge -> 0 (* this is just a dummy value for the electric charge! => CHECK! *), what's the meaning of "dummy value"?...

Interactions violating the charge

Dear Florian, I used SARAH's command MakeUFO to generate the UFO files of model 331-v2, then I started up MadGraph 2.5.4, run the following command: MG5_aMC>import model 331v2 -modelname INFO: load particles INFO: load vertices INFO: The model has interaction violating the charge: charge Kept defini...

A Strange DEFINITION

Dear Florian, I have a puzzling problem. I find in some model files, there are definitions like the following definition codes: DEFINITION[EWSB][GaugeES]={ Fd1 ->{ FdL, 0}, Fd2 ->{ 0, FdR}, Fu1 ->{ Fu1, 0}, Fu2 ->{ 0, Fu2}, Fe1 ->{ Fe1, 0}, Fe2 ->{ 0, Fe2} }; What's the meaning of [EWSB][GaugeES]? I...

About toolbox-2.0.3 with SARAH-4.9.3 and MicrOmegas-4.3.1

Hi Florian, When I use toolbox-2.0.3 with SARAH-4.9.3 and micromegas_4.3.1 by butler, I found some compiling errors. Because micromegas_4.3.1 use different directory name(change sources to include), so we should modify all the related files. It's easy to solve, but I found another problem, in the fi...

About SPhenoInOut.m

Hi Florian, When I use toolbox-2.0.3 with SARAH-4.9.3, I found a compiling error in SPheno/InputOutput_DiracTMSSMLow.f90 about the code lines including Alpha_MSbar(mZ, mW) and alpha_MSbar(mZ, mW). I modified the SARAH-4.9.3/Package/SPheno/SPhenoInOut.m, solved this problem. The attached file is my m...

Re: SARAH-SPheno compiling error

Hi, Florian, Thanks for your reply! Yes, from the physical point of view, I think you are right: "...this will hide the problem mentioned above and people might then do studies which are no longer well defined because they are not aware of the problem". This indeed is not a big problem for my study,...

SARAH-SPheno compiling error

Hello Florian, I am a student from China ITP. I work with Bin Zhu. Bin created a model named DiracTMSSMLow, see the attachment. Under toolbox 2.0.1 or 2.0.3, We did the following steps: 1) write a Mathematica nb file to make spheno/chep files(according to 1109.5147v1) SetDirectory[...]; << SARAH.m; ...
