Charged particle multiplicity fluctuations in simulated pp collisions at \(\sqrt s = 13\;{\text{TeV}}\) 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 \((\eta )\), azimuthal angle (\(\phi\)) and two-dimensional anisotropic \((\eta - \phi )\) phase space. Strong intermittent types of fluctuations have been observed for the UrQMD simulated data. Systematic studies of intermittent fluctuations in terms of scaled factorial moments have been utilized to extract the anomalous fractal dimension in the pseudo-rapidity \((\eta )\), azimuthal angle (\(\phi\)) and two-dimensional anisotropic \((\eta - \phi ) \) phase space. Search for the quark-hadron phase transition in the framework of Ginzburg–Landau theory of the second-order phase transition in the light of the scaled factorial moment method has also been performed.

通过比例因式矩方法研究了超相对论量子分子动力学所产生的最小偏差事件，研究了模拟pp碰撞在\（\ sqrt s = 13 \; {\ text {TeV}} \）下的带电粒子多重性涨落。（UrQMD）模型位于伪快速\（（\（eta）\），方位角（\（\ phi \））和二维各向异性\（（\ eta-\ phi）\）相空间中。对于UrQMD模拟数据，已经观察到强烈的间歇性波动类型。已利用按比例阶乘矩进行的间歇性波动的系统研究来提取伪快速度\（（\ eta）\），方位角（\（\ phi \）中的异常分形维数）和二维各向异性\（（（eta-\ phi）\）相空间。在金兹堡-兰道理论的框架下，根据比例阶乘矩法，还研究了夸克-强子相变。
