Scaling properties of fluctuation results from the PHENIX experiment at RHIC

  • J. T. Mitchell

The PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has made measurements of event-by-event fluctuations in the charged-particle multiplicity as a function of collision energy, centrality, collision species, and transverse momentum in several heavy-ion collision systems. It is observed that the fluctuations in terms of σ 2/μ 2 exhibit a universal power law scaling as a function of Nparticipants that is independent of the transverse momentum range of the measurement.
