Abstract
A measurement of the balance function for Au+Au collision at √SNN=130 GeV was stimulated by the prediction that the width of the balance function should be significantly reduced by late hadronization. As such, a narrowing of the balance function was observed for more central collisions for all charged particle pairs and for charged pion pairs. Only for peripheral collisions was the width consistent with HIJING predictions treating the Au+Au collision as a superposition of independent nucleon-nucleon scatterings.
