Stop decay into c quark

Asked by Juan Pablo on 2018-08-31

Hi,
Im trying to generate the process t1 > c n1 in Madgraph using the mssm model, however I get the following warning from the program "Command "generate t1 > c n1" interrupted with error:
NoDiagramException : No amplitudes generated from process Process: t1 > c n1 @1. Please enter a valid process", I read in a previous post (https://answers.launchpad.net/mg5amcnlo/+question/455773) that it could be due to the decay not been included in the madgraph model, an that I should use the MSSM_SLHA-full model, nonetheless I haven't found it in any version of Madgraph.

Does anyone know where can I find this model ?

Best,

Juan Pablo

just do "import model MSSM_SLHA-full"
and it will work.

Cheers,

Hi Olivier,

Thanks for your suggestion, it work, madgraph indeed import the model, however I still get the same warning when i try to generate t1 > c n1.

What could be the reason to it ?

Hi,

Looks like that interaction is indeed not part of that model.
You should check on the FR website (or the SARAH one) a model which includes the FeynmanRules for such vertex.

Cheers,

Olivier
