Flow and non-flow correlations from four-particle multiplets in STAR
A. H. Tang, STAR Collaboration
Abstract
Elliptic flow results are presented for Au + Au collisions at sNN = 130 GeV in RHIC. This signal is investigated as a function of transverse momentum, rapidity and centrality. Results from four-particle correlation analysis, which can filter out contributions to the flow signal from correlations unrelated to the event reaction plane (``non-flow''), are presented and compared to the conventional method, in which non-flow effects are treated as part of the systematic uncertainty.
