2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/203515We present first results on event-by-event elliptic flow fluctuations in nucleus-nucleus collisions corrected for effects of non-flow correlations where the magnitude of non-flow correlations has been independently measured in data. Over the measured range in centrality, we see large relative fluctuations of 25-50%. The results are consistent with predictions from both color glass condensate and Glauber type initial condition calculations of the event-by-event participant eccentricity fluctuations.4 pages, 3 figures, Quark Matter 2008 ProceedingsNuclear Experimenttext
