Problem with Higgs characterization model, gluon fusion
Dear experts,
I am writing since I am trying to run the Higgs characterization model to calculate the p p > h, p p > h j at NLO.
I followed the README list of recommendations and looked at the launchpad, and everybody seems to have no issues in running the process by doing:
>import model HC_NLO_X0_UFO-heft
>generate p p > x0 / t [QCD] @0
>add process p p > x0 j / t [QCD] @1
However, I am not able to do it. When I type the first generate:
MG5_aMC>generate p p > x0 / t [QCD] @0
Setting the born squared orders automatically in the process definition to QED^2<=2 QCD=0 QNP=0.
If this is not what you need, please regenerate with the correct orders.
-------
No Born diagrams found. Now switching to the loop-induced mode.
Please also cite ref. 'arXiv:1507.00020' when using results from this mode.
-------
Command "generate p p > x0 / t [QCD] @0" interrupted with error:
Exception :

Can you see if I am missing something?
