摘要:

分布的高阶矩及其累积量的研究是研究高能相互作用中粒子间关联的一个敏感工具。在我们以前的工作中,我们已经使用Tsallis $q$统计,NBD,伽玛和移位伽玛分布来描述$π^-$ -核和$p$ -核固定靶相互作用中的多重数分布在不同的能量范围从P $_{Lab}$ = 27 GeV到800 GeV。在本研究中,我们已经扩展了我们的分析,通过计算的时刻,使用Tsallis模型在这些固定的目标实验数据。利用Tsallis模型计算了平均带电多重数及其与能量的关系。结果表明,Tsallis统计量预测的平均带电多重数和矩与实验值吻合较好,表明Tsallis模型在视觉探测器数据上的成功.矩的研究也说明了KNO标度假说在这些能量下是成立的。

英文摘要:

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.
