论文摘要
通过使用不同的统计分布，研究了顶点检测器的正向区域中的不同型号$η$的不同窗口中的$ \ sqrt s $ = 7 tev的质子 - 质子碰撞中的带电颗粒多重性。将三个分布与数据进行了比较，并计算了分布的矩。分析了构成两组的数据，最小偏差事件之一和另一个硬性QCD事件。根据基于潜在的相互作用动力学的不同功能形式得出的分布。该分析补充了LHCB在蒙特卡洛事件发生器方面进行的多样性分析。目前的分析是从不同的角度使用统计分布的。
Charged particle multiplicities in proton-proton collisions measured in the LHCb detector at a centre-of-mass energy of $\sqrt s$=7 TeV in different windows of pseudorapidity $η$, in the forward region of the vertex detector are studied by using different statistical distributions. Three distributions are compared with the data and the moments of the distributions are calculated. The data constituting two sets, one of minimum bias events and another of hard QCD events are analysed. The distributions considered derive from different functional forms based on underlying interaction dynamics. The analysis complements the multiplicity analysis done by LHCb in terms of Monte Carlo event generators. The present analysis is from a different perspective, using statistical distributions.
