Dear Florian,

In the leptoquark model, this field can be a vector boson, which does not come from a new gauge. How can we implement this new field and the corresponding interactions in SARAH?

Best regards,
Keping

Dear Florian, I met 2 problems when working on UFO with MadGraph or HERWIG. First, how can I generate VBF with MadGraph? the default model files of MadGraph do not include the Higgs couplings to the SM fermions. Therefore, we can invoke "generate p p > h j j $$ w+ w- z". However, UFO generated by SA...

Dear Florian, Thank your for your reply. Just one follow up question. Did you consider the latest MadDM for DM study? I generate the UFO files for MadGraph, which is workable. But when I switch to the MadDM, I met some incompatibilities between SPheno output as param_cart.dat and MadDM reader as fol...

Hi Florian, I have question about the possibility of parallelization of MicrOmegas with simple BASH script. We need to run the import different spectrum and rotation matrix files generated by SPheno into MicrOmegas. As default, the MicrOmegas code generated by SARAH can only read the file name as SP...

Hi Florian, I am Keping Xie. I am still a little confused about the SPheno to calculate 1-loop mass. As we know, the mass is the pole of propagator. So in paper 1709.03501, [eig M(p^2=mi^2)]=mi^2 give the right pole. But when I loop at the code, I am not sure whether the code does it correctly. Such...

Hi Florian, Sorry for this bothering. I have tried it out the solution for this problem. The answer lies that I have to rerun all the part of the SARAH codes from the beginning, not just generating the SPheno code part. The key point seems to the following steps. ModelOutput[EWSB, VerticesForLoops -...

Dear Florian, I emailed you once to point it out the phase of doubly chargino in SUSY triplet model. This is not a problem if the observable is determined by the absolute value of couplings, such as decay. But for the loop correction to W, it will create a problem when it involve only one doubly cha...

Dear Florian, Thank you for your reply. The big jump of mass seems to result from the 1-loop corrections. When I switch the option 55 (Calculate loop corrected masses) on, I got a warning Problem in OneLoophh 7.4228703961003235E-016 5.1321914971975651E-016 5.5606867633741281E-016 5.7852942888222340E...

Dear Guy, I am Keping Xie. I am focus on the 1-loop rho parameter calcualtions within SPheno. This is 1-loop is very simple, only need calculate Pi1LoopVZ and Pi1LoopVWm. But when SPheno invoke these two functions in the section of calculating the low energy contraints, the input mass of will update...
