摘要
用单个强子发射源的(βN/〈N〉)1+νKν(βΝ/〈N〉多重数标度分布来刻画多重产生问题,作者在考虑了强子发射源的相对论Doppler运动与AD效应之后,不仅质量效应被明显地揭示出来;而且说明高阶关联的实验数据(s=22-1800GeV)、积分关联参数、奇斜度、峭度和统计矩(〈Nq〉/〈N〉q,q=2,3,4)是质量效应的理论基础;同时,表明基于[c‖0]半群对称性(重整化群方程)的兰道不等式亦得到实验的支持.
Using the saling multiplicty distribution (βN/〈N〉)I+νKν(βN/〈N〉) of a hadron emission source,on account of the relativistic Doppler movement of the source and the effects of anomalous dimension of quantum fields, the mass effects are demonstrated by the experimental data of the correlations with high order (integrated correlation parameter,Skewness,Kurtosis,Statistical moments 〈Nq〉/〈N〉q,q=2,3,4) which are explained by (βN/〈N〉)I+νKν(βN/〈N〉) distribution, where βπ=2[1-2γB(gR)],ν=1/2-4γB(gR) and γB(gR)=-[0.045±0.002]. And the experiments of hadron production support the Landau's inequality of semigroup symmetry in multihadron dynamics.
