Oscillations of moments in high-energy nucleus-nucleus collisions

<正>The definitions of density function and moment of multiplicity distribution are introduced, and the method of moment analysis in e+e- and proton-proton (pp) interactions is extended into nu-cleus-nucleus (AA) interactions. We analyze the data for relativistic nucleus-nucleus collisions and cal-culate the values of Hq for charged particle multiplicity distributions, by which we study systematically the dependences of Hq on incident energy, mass of colliding system, pseudorapidity interval, centrality and truncation of multiplicity. We compare the oscillation structures induced by e+ e- , pp and AA inter-actions , and the comparison and analysis are carried out between experimental data and QCD predic-tion. The latest results are given in this paper.
