D+ production discrepancy to FONLL and MC@NLO at forward-rapidity at 7TeV
I'm computing the production spectrum of D+ at 7TeV with aMC@NLO, using Herwig++ as the event generator.
At mid rapidity, this is consistent with the results from FONLL (arXiv:1205.6344, figure 2), but at forward rapidity (arXiv:1205.6344, figure 3), my results for pT > 5GeV differ from FONLL by north of an order of magnitude. The plotted MC@NLO also diverge by a similar factor, but they do so only at far higher energies.
My results for B+ are fully consistent with FONLL.
To produce D+, I import the loop_sm-c_mass model to have massive charm, remove charm from the proton definition, generate 'p p > c c~ [QCD]', remove jet cuts on charm by adding 'maxjetflavor=3' to the run card (as suggested here: https:/
Is there anything else I should add to my configuration to attain results consistent with FONLL, or are these discrepancies to be expected?
