A search for power-law fluctuations within the framework of the intermittency method is ongoing to locate the critical point of the strongly interacting matter. In particular, experimental data on proton and pion production in heavy-ion collisions are analyzed in transverse-momentum, $p_T$, space.

In this regard, we have studied the dependence of the second scaled factorial moment $F_2$ of particle multiplicity distribution on the number of subdivisions of transverse momentum-interval used in the analysis. The study is performed using a simple model with a power-law two-particle correlation function in $p_T$. We observe that $F_2$ values depend on the size and position of the $p_T$ interval. However, when we convert the non-uniform transverse-momentum distribution to uniform one using cumulative transformation, $F_2$ calculated in subdivisions of the cumulative $p_T$ becomes independent of the cumulative-$p_T$ interval. The scaling behaviour of $F_2$ for the cumulative variable is observed. Moreover, $F_2$ follows a power law with the number of subdivisions of the cumulative-$p_T$ interval with the intermittency index close to the correlation function's exponent.

在间歇法的框架内寻找幂律波动的研究正在进行中，以定位强相互作用物质的临界点。特别是，在横向动量中分析了重离子碰撞中质子和π介子产生的实验数据，${磷}_{吨}$， 空间。

在这方面，我们研究了第二个缩放阶乘矩的相关性 $F_2$分析中使用的横向动量区间细分数的粒子多重性分布。该研究使用具有幂律二粒子相关函数的简单模型进行${磷}_{吨}$. 我们观察到$F_2$ 值取决于大小和位置 ${磷}_{吨}$间隔。然而，当我们使用累积变换将非均匀横向动量分布转换为均匀分布时，$F_2$ 按累计细分计算 ${磷}_{吨}$ 变得独立于累积 -${磷}_{吨}$间隔。的缩放行为$F_2$因为观察到累积变量。而且，$F_2$ 遵循具有累积细分数的幂律 -${磷}_{吨}$ 间隔指数接近相关函数的指数。
