高阶累积量的堆积修正
Pileup corrections on higher-order cumulants
摘要：
我们提出了一种方法来消除堆积事件的贡献，从高阶累积量和事件的粒子分布的时刻。假设堆积事件是由两个独立的单碰撞事件的叠加，我们表明，在每个多重性箱的真实时刻可以得到递归从较低的多重性事件。在校正过程中，必要的信息仅是堆积事件的概率。其他术语是从实验数据中提取的。我们证明，真正的累积量可以成功地重建这种方法在简单的模型。系统地讨论了触发失效和校正参数。
英文摘要：
We propose a method to remove the contributions of pileup events from higher-order cumulants and moments of event-by-event particle distributions. Assuming that the pileup events are given by the superposition of two independent single-collision events, we show that the true moments in each multiplicity bin can be obtained recursively from lower multiplicity events. In the correction procedure the necessary information are only the probabilities of pileup events. Other terms are extracted from the experimental data. We demonstrate that the true cumulants can be reconstructed successfully by this method in simple models. Systematics on trigger inefficiencies and correction parameters are discussed.
