116
So that in the example above QCD=2 restricts the born amplitude to have at[0m
117
most QCD=2 and loop amplitudes at most QCD=2+2 (because QCD loops are considered)[0m
118
> The coupling restrictions after ']' restrict the orders of the matrix element, [0m

namely the squared amplitudes. In the example above QCD=6 correspond to born[0m
120
amplitudes with QCD=2 squared against loop amplitudes with QCD=4, adding up to 6.[0m

virt= : Generate only the loop diagrams, read for MadLoop standalone checks/runs.[0m
124
real= : Generate only the real-emission diagrams, for use with alternative OLP. [0m
125
> For processes without born amplitudes (i.e. loop-induced like g g > z), please use [0m
126
the 'virt=' NLO mode. aMC@NLO cannot integrate these processes, but standalone MadLoop5[0m

can still handle these.[0m
