论文摘要
PP碰撞中的充电粒子多重性波动在$ \ sqrt s $ = 13 TEV已通过量表段落的方法进行了研究（$η$ - $ ϕ $）相位空间。对于URQMD模拟数据，已经观察到了强烈的间歇性波动。利用缩放阶乘矩的间歇性波动的系统研究被用来提取伪重复率（η），方位角角（$ ϕ $）和二维各向异性（$η$ - $ - $ - $ ϕ $）相位空间中的异常分形维度。在Ginzburg-Landau理论的二阶相变理论中，通过分析使用阶乘方法搜索了夸克 - 戴隆相变。
Charged particle multiplicity fluctuations in pp collisions at $\sqrt s$ = 13 TeV have been studied by the method of scaled factorial moment for the minimum bias events generated by Ultra Relativistic Quantum Molecular Dynamics (UrQMD) model in the pseudo-rapidity (η), azimuthal angle ($ϕ$) and two dimensional anisotropic ($η$-$ϕ$) phase space. Strong intermittent type of fluctuations have been observed for the UrQMD simulated data. Systematic studies of intermittent fluctuations in terms of scaled factorial moments was utilized to extract the anomalous fractal dimension in the pseudo-rapidity (η), azimuthal angle ($ϕ$) and two dimensional anisotropic ($η$-$ϕ$) phase space. Search for the quark-hadron phase transition in the framework of Ginzburg-Landau theory of second-order phase transition by the analysis with the factorial moment method has also been performed.
