$\sqrt{s}$ =8,7和2.76时$pp$碰撞中带电粒子的产生LHC时TeV--个例研究

Charged particle production in $pp$ collisions at $\sqrt{s}$=8, 7 and 2.76 TeV at the LHC -- a case study

R. Aggarwal, M. Kaur

摘要:

本文分析了LHC上$\sqrt{s}$ = 8,1,7和1,2.76~TeV的$pp$碰撞的ALICE实验在宽赝快度范围内测量的带电${\text -}$粒子多重数分布。分析提供了一个新的分布,移动Gompertz分布的范围内的高能碰撞粒子产生的理解。将数据与分布进行了比较,并计算了分布的矩。本文还提出了一种改进的分布形式,并用于改进对由两种不同的事件类组成的数据的描述:非弹性和非${\text -}$单${\text -}$衍射以及它们在不同赝快度窗口中的子集,$η$。用于分析数据的分布对不同领域的过程具有广泛的适用性,并补充了ALICE合作在各种LHC事件发生器和IP-Escomma计算方面所做的分析。

英文摘要:

We analyse the charged${\text -}$particle multiplicity distributions measured by the ALICE experiment, over a wide pseudorapidity range, for $pp$ collisions at $\sqrt{s}$=8,\,7\,and\, 2.76~TeV at the LHC.~The analysis offers an understanding of particle production in high energy collisions in the purview of a new distribution, the shifted Gompertz distribution.~Data are compared with the distribution and moments of the distributions are calculated.~A modified version of the distribution is also proposed and used to improve the description of the data consisting of two different event classes; the inelastic and the non${\text -}$single${\text -}$diffractive and their subsets in different windows of pseudorapidity, $η$.~The distribution used to analyse the data has a wide range of applicability to processes in different fields and complements the analysis done by the ALICE collaboration in terms of various LHC event generators and IP-Glasma calculations.
