赝快度窗口中的多重数分布与电荷守恒

Multiplicity distribution in pseudo-rapidity windows and charge conservation

N. Suzuki, M. Biyajima, T. Mizoguchi

摘要:

在全相空间满足电荷守恒的假设下,给出了赝快度窗口中的电荷多重数分布。首先,我们利用CMS和ALICE合作,利用这两种概率分布,分析了LHC赝快度窗口内带电粒子多重数分布的测量结果。一个是负二项分布和泊松分布的卷积,另一个是Glauber-Lachs公式。每个分布被认为是量子光学的类比。接下来,我们分析的数据与双GL公式$|η|<2.4$在7 TeV的CMS合作和$|η|<1.5$在8 TeV的ALICE合作,以描述测量分布的全球结构。

英文摘要:

Charged multiplicity distribution in a pseudo-rapidity window is formulated under the assumption that the charge conservation is satisfied in the full phase space. At first, we analyze measured charged particle multiplicity distributions in pseudo-rapidity windows in LHC by 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 formula. Each distribution is considered as an analogy of the quantum optics. Next, we analyze the data with the double GL formulae for $|η|<2.4$ at 7 TeV by the CMS collaboration and for $|η|<1.5$ at 8 TeV by the ALICE collaboration to describe the global structure of measured distributions.
