Correlations and Fluctuations in STAR

Correlations and Fluctuations in STAR We report measurements for the balance function and <i>pt</i> fluctuations from Au+Au collisions at √{<i>sNN</i>} = 20, 130 and 200 GeV as well as p+p and d+Au collisions at √{<i>sNN</i>} = 200 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 <i>pt</i> fluctuations at all incident energies. Observables related to <i>pt</i> fluctuations are similar for peripheral Au+Au collisions and inclusive p+p collisions while central Au+Au collisions deviate significantly from HIJING predictions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Physica Hungarica Series A, Heavy Ion Physics Springer Journals

Abstract

We report measurements for the balance function and <i>pt</i> fluctuations from Au+Au collisions at √{<i>sNN</i>} = 20, 130 and 200 GeV as well as p+p and d+Au collisions at √{<i>sNN</i>} = 200 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 <i>pt</i> fluctuations at all incident energies. Observables related to <i>pt</i> fluctuations are similar for peripheral Au+Au collisions and inclusive p+p collisions while central Au+Au collisions deviate significantly from HIJING predictions.
