Dear Florian

Sorry for delay. Its working, However I wonder if there is a mathematical difference between SARAH vers 4.8.6 and 4.9.2b2. I'm observing quite a difference in SPheno outputs, probably due to tadpole equations.

Also I believe Oliver didn't updated MG5 yet after your suggestions, I'll let you know if I can catch any difference.

Thanks for your help
Best regards

Hi,

good that this works.
How big are the differences that you get? There have been small changes, which might give differences in the masses on the permille-percent level. If you find more, could you please provide your input file.

Cheers,
Florian

Dear Florian

After playing abit around, I realized that probably I hit the edge. So far I been able to reproduce some of my previous results but I observed 1 to 3 GeV difference in scalar neutrino masses and neutralino masses. Adding both SPheno outputs to the attachment. Don't know if its good or bad result can be adjusted, so its not that important but I wanted to understand the reason behind the difference.

Also I dont know if there is a final state dependent reading problem in MG5, which sounds really meaningless, but MG5 doesn't read param card when I have jet final states but it works when I have say neutralino final states, here is the error

process is mono and dijet + DM

MadGraph5Error : decay (23,) not define

Do you think it is because of SPheno or should I tell them, I could understand SPheno specific blocks had compatibility problems but I can not understand minpar, softmasses etc.

Thank you very much

Best regards

Hi,

there have been small changes in 4.9.0 in the matching to the SM. This gives for your point a bit different value of the running bottom Yukawa coupling which obviously has some impact on the running.

No idea about the MG problem. It complaints about the missing decay of the Z-boson (23) which are indeed not calculated by SPheno by default. However, I don't know if it needs it for this particular process.
