Hi,

In MadGraph5, they are no special meaning for "darkmatter" so they are no way to define a particle as dark matter.
Now you have some other code, which can use the pdg code to determine that your particle is a darkmatter (code like plotting ones typically use that).

If you use some MG5aMC plugin (like maddm or maddump), then you have special meaning for darkmatter and those plugin introduce special syntax for that.

Cheers,

Olivier
