摘要:

我们提出的第一个结果,在核-核碰撞事件的椭圆流波动校正的非流相关性的影响,非流相关性的幅度已被独立测量的数据。在中心性的测量范围内,我们看到25- 50%的相对波动。结果是一致的预测从彩色玻璃冷凝物和Glauber型初始条件计算的事件,事件参与者的偏心率波动。

英文摘要:

We 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.
