Description

Hi,

I have a question regarding Gluino Gluino pair production in

SHERPA. I am trying to use Amegic to do this, however, it appears that it always throw an exception:Cluster_Algorithm::Set4Colours(): Cannot set colours for. Do you kindly tell me if anyone has already generate this process before. It is quite interesting that I could not have gg>gg process generated with Amegic as well.

Thanks,

Wenhan

Dear Wenhan,

SUSY QCD particles cannot currently be treated with Sherpas parton shower module (more precisely by the interface between matrix element and parton shower). This is a known shortcoming of version 1.2.0 and is likely to be resolved in version 1.2.1.

Regards

Stefan

Dear Wenhan,

Release 1.2.1 has been published now, so feel free to try again and report back if it still doesn't work.

Cheers, Frank
