论文摘要
对分布及其累积物的高阶力矩的研究构成了一种敏感工具，用于研究高能相互作用中产生的粒子之间的相关性。在我们以前的工作中，我们使用了TSALLIS $ Q $统计，NBD，Gamma和移位的Gamma分布来描述$π^ - $ -Nucleus和$ P $ -Nucleus固定目标相互作用的多重分布，从P $ _ {lab} $ = 27 GEV到800 GEV等各种能量。在本研究中，我们通过在这些固定目标实验数据中使用Tsallis模型来计算矩来扩展分析。通过使用TSALLIS模型，我们还计算了平均电荷多样性及其对能量的依赖性。发现Tsallis统计数据的平均电荷多样性和矩与实验值非常吻合，并表明TSALLIS模型在来自视觉检测器的数据上取得了成功。对矩的研究还表明，KNO缩放假设在这些能量方面有好处。
The study of higher-order moments of a distribution and its cumulants constitute a sensitive tool to investigate the correlations between the particle produced in high energy interactions. In our previous work we have used the Tsallis $q$ statistics, NBD, Gamma and shifted Gamma distributions to describe the multiplicity distributions in $π^-$ -nucleus and $p$ -nucleus fixed target interactions at various energies ranging from P$_{Lab}$ = 27 GeV to 800 GeV. In the present study we have extended our analysis by calculating the moments using the Tsallis model at these fixed target experiment data. By using the Tsallis model we have also calculated the average charged multiplicity and its dependence on energy. It is found that the average charged multiplicity and moments predicted by the Tsallis statistics are in much agreement with the experimental values and indicates the success of the Tsallis model on data from visual detectors. The study of moments also illustrates that KNO scaling hypothesis holds good at these energies.
