Net charge fluctuations in Au+Au collisions at root s(NN)=130 GeV Academic Article uri icon

abstract

  • We present the results of charged particle fluctuations measurements in [Formula Presented] collisions at [Formula Presented] using the STAR detector. Dynamical fluctuations measurements are presented for inclusive charged particle multiplicities as well as for identified charged pions, kaons, and protons. The net charge dynamical fluctuations are found to be large and negative providing clear evidence that positive and negative charged particle production is correlated within the pseudorapidity range investigated. Correlations are smaller than expected based on model-dependent predictions for a resonance gas or a quark-gluon gas which undergoes fast hadronization and freeze-out. Qualitative agreement is found with comparable scaled [Formula Presented] measurements and a heavy ion jet interaction generation model calculation based on independent particle collisions, although a small deviation from the [Formula Presented] scaling dependence expected from this model is observed. 2003 The American Physical Society.
