Charged particle multiplicities are studied in proton-proton collisions in the forward region at a centre-of-mass energy of [Formula: see text]TeV with data collected by the LHCb detector. The forward spectrometer allows access to a kinematic range of [Formula: see text] in pseudorapidity, momenta greater than [Formula: see text] and transverse momenta greater than [Formula: see text]. The measurements are performed using events with at least one charged particle in the kinematic acceptance. The results are presented as functions of pseudorapidity and transverse momentum and are compared to predictions from several Monte Carlo event generators.
利用大型强子对撞机底夸克探测器（LHCb）收集的数据，在质心能量为[公式：见原文]TeV的情况下，对前向区域质子 - 质子碰撞中的带电粒子多重性进行了研究。前向谱仪可探测到赝快度在[公式：见原文]、动量大于[公式：见原文]以及横向动量大于[公式：见原文]的运动学范围。测量是使用在运动学接受度内至少有一个带电粒子的事件进行的。结果以赝快度和横向动量的函数形式呈现，并与几个蒙特卡罗事件发生器的预测结果进行了比较。
