MadGraph 5 Process Cards

Note that the web didn't allow all the possibility of a personal computer. For such reason some proc_card maybe not functional or refused. In general:

You cann't specify any path in the proc_card
You cann't use any external script

Process	card	Comments
top pair	generate p p > t t~ QED=2 QCD=2 output launch	By default, MadGraph 5 imports the standard model. Therefore, no specic command required for that. Note that if the couplings are not present, MG5 will take the minimal QED one for process having only QED/QCD order. And will not restrict the order otherwise.
Stop pair	import model mssm generate p p > t1 t1~ add process p p > t2 t2~ output -f
Slepton pair production	import model mssm define sl- = el- mul- ta1- er- mur- ta2- define sl+ = el+ mul+ ta1+ er+ mur+ ta2+ generate p p > sl+ sl- output	Example using user define multi-particles
W jets	generate p p > w+ j j output -f	Note that QED is set automaticaly to it's minimal value (i.e. one)
W jets	generate p p > w+ j j QED=3 output -f	Including all QED contributions
Gluino decay	generate go > ul > u~ u n1 output	The result will be given in GeV
top pair decay	generate p p > t t~ QED=0, \ (t > W+ b, W+ > j j), \ (t~ > w- b~, W- > l- vl~) output	note that the "\" allow the line splitting.
