We discuss production of charm and bottom quarks at forward rapidity in 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.
我们讨论了大型强子对撞机（LHC）碰撞中前向快度下粲夸克和底夸克的产生情况，更新了对[公式：见正文] TeV运行的量子色动力学（QCD）预测。我们表明，虽然绝对产率受到以标度不确定性为主的较大理论系统误差的影响，但相对于在7 TeV精确测量的产率的增加可以以百分之几的精度进行预测，这足以突出对胶子分布函数的敏感性。
