The inclusive production cross sections at forward rapidity of [Formula: see text], [Formula: see text], Formula: see text and Formula: see text are measured in [Formula: see text] collisions at [Formula: see text] with the ALICE detector at the LHC. The analysis is based on a data sample corresponding to an integrated luminosity of 1.35 pb[Formula: see text]. Quarkonia are reconstructed in the dimuon-decay channel and the signal yields are evaluated by fitting the [Formula: see text] invariant mass distributions. The differential production cross sections are measured as a function of the transverse momentum [Formula: see text] and rapidity [Formula: see text], over the ranges [Formula: see text] GeV/c for [Formula: see text], [Formula: see text] GeV/c for all other resonances and for [Formula: see text]. The measured cross sections integrated over [Formula: see text] and [Formula: see text], and assuming unpolarized quarkonia, are: [Formula: see text] [Formula: see text]b, [Formula: see text] [Formula: see text]b, [Formula: see text] nb and [Formula: see text] nb, where the first uncertainty is statistical and the second one is systematic. The results are compared to measurements performed by other LHC experiments and to theoretical models.
利用大型强子对撞机（LHC）上的ALICE探测器，在质心能量为[公式：见文本]的[公式：见文本]碰撞中，测量了[公式：见文本]、[公式：见文本]、公式：见文本和公式：见文本在正向快度下的包含性产生截面。该分析基于一个对应于1.35 pb[公式：见文本]积分亮度的数据样本。夸克偶素在双μ子衰变通道中重建，信号产额通过拟合[公式：见文本]不变质量分布来评估。微分产生截面作为横向动量[公式：见文本]和快度[公式：见文本]的函数进行测量，测量范围为：对于[公式：见文本]，[公式：见文本]GeV/c；对于所有其他共振态，[公式：见文本]GeV/c；对于[公式：见文本]，[公式：见文本]。在[公式：见文本]和[公式：见文本]上积分并假设夸克偶素未极化的情况下，测量得到的截面为：[公式：见文本][公式：见文本]b、[公式：见文本][公式：见文本]b、[公式：见文本]nb和[公式：见文本]nb，其中第一个不确定度是统计性的，第二个是系统性的。将结果与其他LHC实验的测量结果以及理论模型进行了比较。
