Charged multiplicity distribution (MD) in a pseudo-rapidity window is formulated under the assumption that the charge conservation is satisfied in full phase space. At first, we analyze measured charged particle MDs in pseudo-rapidity windows in the LHC experiments by the CMS and ALICE collaborations with the two probability distributions. One is the convolution of negative binomial and Poisson distributions, and the other is the Glauber–Lachs (GL) formula. Each distribution is considered as an analogy of the quantum optics. Next, we analyze the data with the sum of two GL formulae for |η| < 1.5 and |η| < 2.4 at 7 TeV by the CMS collaboration, and for |η| < 1.5 at 7 and 8 TeV by the ALICE collaboration to describe the global structure of measured distributions.

伪快速窗口中的电荷多重分布 (MD) 是在全相空间满足电荷守恒的假设下制定的。首先，我们通过 CMS 和 ALICE 合作分析了 LHC 实验中伪快速窗口中测量的带电粒子 MDs 与两种概率分布。一种是负二项式和泊松分布的卷积，另一种是 Glauber-Lachs (GL) 公式。每个分布都被认为是量子光学的类比。接下来，我们用两个 GL 公式的总和来分析数据 | η | < 1.5 和 | η | < 2.4 at 7 TeV 由 CMS 合作，并为 | η| < 1.5 at 7 和 8 TeV 由 ALICE 合作描述测量分布的全局结构。
