Oscillations of moments in high-energy nucleus-nucleus collisions

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 nucleus-nucleus (AA) interactions. We analyze the data for relativistic nucleus-nucleus collisions and calculate the values of H_q for charged particle multiplicity distributions, by which we study systematically the dependences of H_qon 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 interactions, and the comparison and analysis are carried out between experimental data and QCD prediction. The latest results are given in this paper.
