Madgraph version

[amaliab2]

Hello,
I am running a BSM model in MadGraph with MG5_aMC_v2_3_3, the model files were generated by SARAH and for the param_card.dat I use the SPheno.spc. I am having a problem with a decay, and I asked the MadGraph team about this and they say I have to update the version, so I was wondering which version of MadGraph should I use with files generated by SARAH and with the param_card.dat the SPheno.spc?

Thank you

Hi,

I tested some time ago v2_6_0 and it worked fine. Note, it might be that the SLHA reader of MG has problems reading the DECAY1L blocks. If you have those in your spc file, try to delete them (or run SPheno with flag 16 set to 0).

Cheers

Thank you for your reply.

Actually, in the LesHouches file there is no flag 16 and there are no DECAY1L blocks in the SPheno.spc file.

On the other hand, I tried to use MG5_aMC_v2_6_0, but once I launch this is what I get:

Error detected in "generate_events run_01"

What could be the problem here?
Thank you.

Did you set

Code: Select all

 78 1               # Output for MadGraph (writes also vanishing blocks) 

?

[amaliab2]

Actually, the flag 78 is not in my LesHouches file.
I am attaching the file.

Thank you!

[FStaub]

Maybe you use an old SARAH version?

[amaliab2]

Yes, I am using SARAH.4.9.1. When I try compiling the model in SPheno using the output from SARAH.4.12.1 I get and error. I am attaching the SPheno.m file, maybe it needs updating to work with the new version?

Thank you!
Amalia

What kind of error message?
I don't think that the origin is SPheno.m, but some recent updates which might not be totally compatible with your model.

Cheers,

Hello,
This is the error I get from SPheno:

Thank you!

It seems that you use an old Mathematica version which doesn't know StringRiffle.
If you don't need loop decays, try the option IncludeLoopDecsys->False of MakeSPheno
