> Notice that in this format, decay chains are not allowed.[0m
> The LoopOrder(s) defined specify the kind of loops to consider (only QCD for now).[0m
> The coupling restrictions before '[' restrict the orders of born *amplitudes*.[0m
So that in the example above QCD=2 restricts the born amplitude to have at[0m
most QCD=2 and loop amplitudes at most QCD=2+2 (because QCD loops are considered)[0m
> 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
amplitudes with QCD=2 squared against loop amplitudes with QCD=4, adding up to 6.[0m
> The optional <NLO_mode=> can be any of the following ('all=' by default if absent):[0m
all= : Generate all the real-emission and loop diagrams, ready for aMC@NLO runs.[0m
virt= : Generate only the loop diagrams, read for MadLoop standalone checks/runs.[0m
real= : Generate only the real-emission diagrams, for use with alternative OLP. [0m
> For processes without born amplitudes (i.e. loop-induced like g g > z), please use [0m
the 'virt=' NLO mode. aMC@NLO cannot integrate these processes, but standalone MadLoop5[0m
can still handle these.[0m
