Abstract
We present measurements of net charge fluctuations in Au+Au collisions at √[subscript s[superscript [NN]]=19.6, 62.4, 130, and 200 GeV, Cu+Cu collisions at √[subscript s[superscript [NN]]=62.4 and 200 GeV, and p+p collisions at √s=200 GeV using the dynamical net charge fluctuations measure ν[subscript +-,dyn]. We observe that the dynamical fluctuations are nonzero at all energies and exhibit a modest dependence on beam energy. A weak system size dependence is also observed. We examine the collision centrality dependence of the net charge fluctuations and find that dynamical net charge fluctuations violate 1/N[subscript ch] scaling but display approximate 1/N[subscript part] scaling. We also study the azimuthal and rapidity dependence of the net charge correlation strength and observe strong dependence on the azimuthal angular range and pseudorapidity widths integrated to measure the correlation.
