论文摘要
在间歇性分析的框架内，正在进行寻找关键波动的搜索，以在量子染色体动力学相图中找到可能的临界点。在这项研究中，临界蒙特卡洛（CMC）模型的自相似临界波动已被纳入级联超偏移量子分子动力学（URQMD）模型中。该混合级会+CMC模型在$ \ sqrt {s_ \ mathrm {nn}} $ = 7.7-200 GEV中表现出对带电粒子的缩放阶乘矩阵的明确幂律行为。通过将URQMD+CMC模型与Star实验的级联模型进行比较，发现计算出的缩放指数的值落入实验测量范围内时，当1-2 \％的间歇性波动信号添加到URQMD样本中。
Within the framework of intermittency analysis, a search for critical fluctuations is ongoing to locate the possible critical point in the quantum chromodynamics phase diagram. In this study, self-similar critical fluctuations from a critical Monte Carlo (CMC) model have been incorporated into the cascade ultrarelativistic quantum molecular dynamics (UrQMD) model. This hybrid UrQMD+CMC model exhibits a clear power-law behavior of scaled factorial moment for charged particles in Au+Au collisions at $\sqrt{s_\mathrm{NN}}$ = 7.7-200 GeV. By comparing the UrQMD+CMC model results with those from the STAR experiment, it is found that the value of a calculated scaling exponent falls in the range of the experimental measurement when 1-2 \% signal of intermittency fluctuations is added into the UrQMD sample.
