Comment 3 for bug 1949450

Hi Olivier,

I'm not sure how to fix this in the best way. The issue is, as far as I can tell, that there is nowhere in the model/code that the new g-g-H interaction contains, in fact, a strong coupling squared. It's always simply labelled as a new order 'QNP', but not that 'QNP=QCD^2*QED'. Hence, the code doesn't know that in the QCD running, it should include two extra powers of alpha_S coming from QNP as compared to what is expected from the QCD power alone.

I guess the cleanest way would be to fix this directly in the model. But since I'm not familiar with UFO, I do not know if this feature exists and how madgraph treats it in NLO processes.
