    "abstract": "The cumulant method is applied to study elliptic flow ($v_2$) in Au+Au\ncollisions at $\\sqrt{s}=200$AGeV, with the UrQMD model. In this approach, the\ntrue event plane is known and both the non-flow effects and event-by-event\nspatial ($\\epsilon$) and $v_2$ fluctuations exist. Qualitatively, the hierarchy\nof $v_2$\u0027s from two, four and six-particle cumulants is consistent with the\nSTAR data, however, the magnitude of $v_2$ in the UrQMD model is only 60% of\nthe data. We find that the four and six-particle cumulants are good measures of\nthe real elliptic flow over a wide range of centralities except for the most\ncentral and very peripheral events. There the cumulant method is affected by\nthe $v_2$ fluctuations. In mid-central collisions, the four and six-particle\ncumulants are shown to give a good estimation of the true differential $v_2$,\nespecially at large transverse momentum, where the two-particle cumulant method\nis heavily affected by the non-flow effects.",
