Beam-energy and system-size dependence of dynamical net charge fluctuations

Abstrak
We present measurements of net charge fluctuations in Au + Au collisions at $\sqrt {s_{NN} } $ = 19.6, 62.4, 130, and 200 GeV, Cu + Cu collisions at $\sqrt {s_{NN} } $ = 62.4, 200 GeV, and p + p collisions at $\sqrt s $ = 200 GeV using the net charge dynamical fluctuations measure ν+ −,dyn. The dynamical fluctuations are non-zero at all energies and exhibit a rather modest dependence on beam energy. We find that at a given energy and collision system, net charge dynamical fluctuations violate 1/Nch scaling, but display approximate 1/Npart scaling. We observe strong dependence of dynamical fluctuations on the azimuthal angular range and pseudorapidity widths.
