论文摘要
在LHC融合模型的框架中研究了LHC能量下PP相互作用的两个分离速度间隔中粒子数量之间的相关性的强大变量的性质。我们在冲击参数平面中执行字符串分布的MC模拟,以考虑PP碰撞的实验条件。我们说明字符串融合过程,导致弦簇的形成,将有限晶格(网格)嵌入撞击参数平面中。结果,我们发现了该变量对观测窗口中心之间的距离的依赖性及其在几个初始能量下的Minbias PP碰撞的宽度。分析这些依赖关系,我们可以提取有关字符串簇属性的重要信息。我们表明,在LHC能量的PP碰撞中,字符串融合效应对这种强度强度变量的行为产生了重大影响。这些影响的作用是随着碰撞的初始能量和中心性的增加而增加。特别是,我们发现,该变量随着初始能量的增加是由于在PP相互作用中引起的弦构构中的融合字符串簇的一部分而发生的。
The properties of the strongly intensive variable characterizing correlations between the number of particles in two separated rapidity interval in pp interactions at LHC energies are studied in the framework of the string fusion model. We perform the MC simulations of string distributions in the impact parameter plane to take into account the experimental conditions of pp collisions. We account the string fusion processes, leading to the formation of string clusters, embedding a finite lattice (a grid) in the impact parameter plane. As a result, we found the dependence of this variable both on the distance between the centers of the observation windows and their width for the minbias pp collisions at several initial energies. Analyzing these dependencies we can extract the important information on the properties of string clusters. We show that in pp collisions at LHC energies the string fusion effects have a significant impact on the behavior of this strongly intensive variable. The role of these effects is increasing with the initial energy and centrality of collisions. In particular, we found that the increase of this variable with initial energy takes place due to the growth of the portion of the fused string clusters in string configurations arising in pp interactions.
