Make some requirements for the intermediate propagator

Asked by 王世钰

Dear madgraph expert, I now need to require that the intermediate propagator of the follow-up process of my generate must have an X particle, of course, it can also contain other particles (that is, all the X particles in the intermediate process are not required). Is there such a command? , By the way, is there any literature such as the madgraph command list, if you have, can you send a link?

The best way to have all syntax is to use the help command.
Otherwise, you have the various paper that describe everything. But the help command is stuff to read.

Cheers,

Olivier

Thank you very much for your help. In the generate command of madgraph, I found a $ command, but after many times of practice and application, I don’t know what is the use of this command. I hope you can explain it to me.

The best explanation for that command is in tutorial:
