Gluon PDF constraints from the ratio of forward heavy-quark production at the LHC at [Formula: see text] and 13 TeV

We discuss production of charm and bottom quarks at forward rapidity in pp collisions at the LHC, updating the QCD predictions for the run at [Formula: see text]  TeV. We show that, while the absolute rates suffer from large theoretical systematics, dominated by scale uncertainties, the increase rel...

description We discuss production of charm and bottom quarks at forward rapidity in pp collisions at the LHC, updating the QCD predictions for the run at [Formula: see text]  TeV. We show that, while the absolute rates suffer from large theoretical systematics, dominated by scale uncertainties, the increase relative to the rates precisely measured at 7 TeV can be predicted with an accuracy of a few percent, sufficient to highlight the sensitivity to the gluon distribution function.
