1. Fluctuations and correlations in STAR

Author

Westfall, Gary D and Collaboration), (for the STAR

Abstract

We report measurements for the balance function, pt fluctuations and net charge fluctuations from Au+Au collisions at , 130 and 200 GeV as well as p+p and d+Au collisions at GeV using STAR at RHIC. For Au+Au collisions at 200 GeV, we observe a narrowing of the balance function in central collisions. We observe dynamic pt fluctuations at all incident energies. Observables related to pt fluctuations and net charge fluctuations are similar for peripheral Au+Au collisions and inclusive p+p collisions while central Au+Au collisions deviate significantly from HIJING predictions.

2. Widths of the balance function for charged kaon pairs from Au+Au at <MATH ALT=""/> GeV and p+p at <MATH ALT=""/> GeV at RHIC

Author

Westfall, Gary D and Collaboration), (for the STAR

Abstract

The balance function is based on the principle that charge is locally conserved when particles are pair produced. Balance functions have been measured for identified charged pion pairs, and identified charged kaon pairs in Au+Au collisions at GeV and p+p collisions at GeV at the relativistic heavy ion collider using STAR. Balance functions for all observed particles from Au+Au scale smoothly with centrality to the p+p value. Balance functions for pions are narrower in central collisions than in peripheral collisions consistent with trends predicted by models incorporating late hadronization. Balance functions for kaon pairs also represent a strangeness balance. Balance functions for kaons are narrower than those for pion pairs and show less dependence on centrality.
