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. |
NAME | MODEL | PROCESS(ES) | QCD | QED | Comment |
---|---|---|---|---|---|
H + 2 jets | sm | pp> hjj | 0 | 99 | Higgs production through weak-boson fusion. |
H + 2 jets | heft | pp> hjj | 99 | 0 | Higgs production through a top loop (shrunk). |
W + up to 3 jets | sm | pp> e- ve~ pp> e- ve~ j pp> e- ve~ jj pp> e- ve~ jjj | 99 | 2 | Inclusive production of a W-boson in association with 0,1,2,3 jet. Events generated with this code are suitable to be run through a matching algorithm (such as MLM or CKKW) with a PS, so to obtain an inclusive W+jet sample. |
ttbb: signal and backgrounds | sm | pp>h>tt~bb~ pp>tt~bb~ pp>tt~bb~/h | 2 99 2 | 2 0 2 | Joint generation of signal and background for associated production of Higgs and a pair of tops. |
single top | sm | pp>tj, t~j pp>tb~,tb~ pp>tW-,t~W+ | 0 0 1 | 2 2 1 | Joint generation of the three channels for single top production: t-channel, s-channel and W-associated. |
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. |
