在CERN SPS装置上，用150 AGeV/c的40 Ar +45 Sc碰撞寻找了致密强相互作用物质的临界点。测量了质子多重性分布的二阶标度阶乘矩与横动量空间细分数的关系。使用横向动量和累积横向动量进行不透明度分析。这是第一次，统计上独立的数据集用于每个细分号码。所获得的结果未表明任何统计学显著的不稳定性模式。通过与幂律模型的比较，得到了关联质子对比例和关联函数幂的上限。
The critical point of dense, strongly interacting matter is searched for at the CERN SPS in40Ar +45Sc collisions at 150AGe V /c. The dependence of second-order scaled factorial moments of proton multiplicity distribution on the number of subdivisions of transverse momentum space is measured. The intermittency analysis is performed using both transverse momentum and cumulative transverse momentum. For the first time, statistically independent data sets are used for each subdivision number. The obtained results do not indicate any statistically significant intermittency pattern. An upper limit on the fraction of correlated proton pairs and the power of the correlation function is obtained based on a comparison with the Power-law Model developed for this purpose.
