The oscillation of moment in high-energy nucleus-nucleus collision
Yang Hong · Journal of Central China Normal University · 2000
This paper introduces the definitions of density function and moment of multiplicity distributions,and extends the moment analysis method in e +e and pp interactions into the nucleus nucleus interactions.It also analyses the data for relativistic nucleus nucleus collisions from EMU01 experiment,calculates the ratio H q of factorial cumulant and factorial moment for charged particle multiplicity distributions,by which it studies systematically the dependences of H q on incident energy,mass of projectile and target,pseudorapidity interval and collision centrality and compares the oscillation structure of the simple colliding system (e +e ,pp) and the complicated one(nucleus nucleus) to search for the possible physics connecting with quantum chromodynamics process.
