论文摘要
当系统接近临界点时，局部密度波动预计将作为通用幂律扩展。通过测量（$η$，$ ϕ $）相位空间的标准化阶乘矩，在间歇性的框架内研究了这种幂律的波动。报道了使用毕曲（Pythia8/angantyr）在2.76 TEV和5.02 TEV的PB-PB碰撞中对电荷颗粒进行的间歇性分析的观测和结果。对于狭窄的p $ _t $ bins研究的任何中心性，我们都没有观察到粒子生成的缩放行为。缩放指数$ν$不显示对中心性范围的依赖。
Local density fluctuations are expected to scale as a universal power-law when the system approaches critical point. Such power-law fluctuations are studied within the framework of intermittency through the measurement of normalized factorial moments in ($η$, $ϕ$) phase space. Observations and results from the intermittency analysis performed for charged particles in Pb-Pb collisions using PYTHIA8/Angantyr at 2.76 TeV and 5.02 TeV are reported. We observe no scaling behaviour in the particle generation for any of the centrality studied in narrow p$_T$ bins. The scaling exponent $ν$ shows no dependence on the centrality ranges.
