Abstract

By the model with the fusion of quark-gluon strings on a transverse lattice the correlations between observables from separated rapidity intervals in high-energy hadronic interactions are considered. The asymptotes of the long-range rapidity correlation coefficients between the multiplicities (n–n) and between the event-mean transverse momentum and the multiplicity of charged particles (pt–n) in these observation windows at large string density were explicitly calculated with the additional condition fixing the total number of initial strings. It is shown that this condition, which imitates in our model the fixation of the collision centrality class, has a significant impact on the behavior of the n–n and pt–n correlation coefficients for both homogeneous and inhomogeneous distribution of strings in the transverse plane.

横向格上带字符串融合的模型的远程快速相关性的计算

摘要

通过将夸克-胶子串融合在横向晶格上的模型，考虑了在高能强子相互作用中来自分离的速度区间的可观测值之间的相关性。在这些观测窗口中，在大弦密度下，多重性（n – n）之间以及事件平均横向动量和带电粒子的多重性（pt – n）之间的远距离快速相关系数的渐近线是用以下公式明确计算的：确定初始字符串总数的附加条件。结果表明，这种情况在我们的模型中模仿了碰撞中心性类别的固定，对n –的行为具有重大影响。n和pt – n相关系数对于弦在横向平面上的均匀分布和不均匀分布都是如此。
