Excitation Function of Net Charge Fluctuations at RHIC

Excitation Function of Net Charge Fluctuations at RHIC We present measurements of dynamical net charge fluctuations in Au+Au collisions at √{<i>sNN</i>} = 0, 130 and 200 GeV using the measure &nu;+-, dyn. The dynamical fluctuations are finite and exhibit a rather modest dependence on beam energy. We also find they violate the trivial 1/<i>N</i> scaling expected for nuclear collisions consisting of independent nucleon–nucleon interactions. We speculate this may be due to a combination of thermalization and radial flow effects. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Physica Hungarica Series A, Heavy Ion Physics Springer Journals

Abstract

We present measurements of dynamical net charge fluctuations in Au+Au collisions at √{<i>sNN</i>} = 0, 130 and 200 GeV using the measure &nu;+-, dyn. The dynamical fluctuations are finite and exhibit a rather modest dependence on beam energy. We also find they violate the trivial 1/<i>N</i> scaling expected for nuclear collisions consisting of independent nucleon–nucleon interactions. We speculate this may be due to a combination of thermalization and radial flow effects.
