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:
  1. You cann't specify any path in the proc_card
  2. You cann't use any external script

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.

SUSY decay chain mssm uu>(ul>u n1)(ul>u(n2>e+e-n1)) 2 4 Select only diagrams compatible with the specified decay chain. Specified intermediate particles are restricted to be close to the mass shell (within a number of widths specified by the bwcutoff parameter in the run_card.dat).
Note that multiparticle labels can be used only in initial and final states, not for intermediate particles.
