The best way to generate NLO event (ggH)
Hello all,
I am generating the following process:
import model heft
generate p p > h j, h > l- vl~ l+ vl
I am struggling to work out at what order MadGraph calculates this event at (presumably leading order?). I would like to calculate the cross-section at next-leading-order, for which I think I need to specify a QCD value (although I'm not sure what). I have assumed QED is not important here as the processes do not involve photons - is this assumption correct?
eg. is the following sufficient?
generate p p > h j, l- vl~ l+ vl QCD=2
I thought if I specified a higher QCD value, there would be additional diagrams (eg. with trees and loops), but this does not appear to be the case.
Thanks for any help,
James
