Problem Of Generating Process

Asked by shibasipu

Hello Madgraph Team,
                                         I am generating the following process in the context of SM. It is showing the command interrupted with error. Please have a look to the following.

MG5_aMC> generate p p > h vl vl~ , ( h > j j )

Hi,

They are no tree-level diagram in the SM for such process, so this is correct.
In version2.3 which should be in beta very soon, it will be possible to generate loop induce process but this is not the case yet.

The syntax will be
generate p p > h vl vl~ [QCD]

The decay-chain syntax will not be supported for the moment.

Cheers,

Olivier
